Introduction
Historically, Vietnam’s mountainous and forested landscapes formed a vital foundation for its economic, cultural, and strategic development. In the premodern era, forests supplied timber for construction and shipbuilding, yielded a wide range of valuable products, and served as natural frontiers essential to the defense of the realm. Yet scholarship on forests and human-forest relations in Vietnamese history remains limited. Most existing research concentrates on the colonial and modern periods rather than earlier dynastic contexts.
McElwee’s Forests Are Gold: Trees, People, and Environmental Rule in Vietnam (2016) traces the evolution of forest management from the colonial era to the Reform (Doi Moi) period, highlighting how socio-economic transformations contributed to deforestation and the emergence of barren hills. Likewise, Aso’s Rubber and the Making of Vietnam: An Ecological History, 1897–1975 (2018) examines the political ecology of rubber cultivation and its influence on medicine, agriculture, and nation-building. Thomas (2009) further explored the institutionalization of conservation under French forestry in Indochina. While insightful, these studies share a common temporal focus on modernity.
In contrast, research on timber and forest resources in early modern Vietnam is exceptionally scarce. Only two short studies exist: Nguyen (2022a) on agarwood (tram huong) in Vietnam’s economic history, and Nguyen (2022b) on timber exploitation and management between the fifteenth and eighteenth centuries. Beyond these, both Vietnamese and Western scholarship have paid limited attention to premodern forest exploitation and administration. Addressing this gap is essential not only to enrich Vietnamese environmental historiography but also to reveal how forest management functioned as a mechanism of governance in precolonial Southeast Asia.
This study approaches the subject through the analytical frameworks of environmental governance and political ecology, situating forest management within broader statesociety-nature interactions. By examining how the Nguyen state conceptualized, regulated, and mobilized forest resources, it reconstructs administrative mechanisms while revealing how these practices reflected deeper notions of environmental order, sovereignty, and statecraft. By linking empirical reconstruction with conceptual interpretation, the article helps bridge the divide between descriptive and analytical approaches in Vietnamese environmental history.
Extending the temporal horizon backward from the colonial to the dynastic period enables a comparative perspective on institutional continuity and change. By juxtaposing Nguyen dynasty regulations with those of the Le and Tay Son dynasties, the study traces the evolution of forest governance from tributary and corvée-based extraction to a more bureaucratized and codified system. These continuities and contrasts foreshadow the emergence of colonial forestry in Indochina during the late nineteenth century.
Accordingly, this article offers a new perspective on the environmental history of premodern Vietnam by focusing on the exploitation, management, and perception of forests under the Nguyen dynasty (1802–1883). This period was selected because it marks the final Vietnamese monarchy, characterized by abundant and well-preserved official records providing detailed documentation of forest-related policies, and because its territorial scope corresponds closely to modern Vietnam. Through this focus, the study seeks to clarify how the Nguyen state balanced extraction and protection, order and ecology, thereby contributing to the longue durée of environmental governance in Vietnamese history.
Research Methods
Adopting an environmental history approach, this article employs qualitative historical analysis to examine chronicles and geographical accounts that document the exploitation, use, and management of forests, as well as contemporary perceptions of their significance during the Nguyen period. The principal source is the Veritable Records of the Great South, compiled by the Nguyen dynasty’s Office of State Historiography. Although primarily political and administrative in focus, the Records contain numerous entries on natural phenomena—forests, mountains, rivers, and seas—revealing the extent to which environmental conditions intersected with governance.
A second major source is the Comprehensive Encyclopaedia of the Great South, produced by the same institution. This encyclopaedia offers systematic descriptions of provincial geography, climate, population, scenic sites, mountains, rivers, and natural products, thereby providing a complementary spatial perspective on forest management across the realm. Together, these two works constitute the most extensive and reliable corpus for examining forest governance in nineteenth-century Vietnam.
Grounded in a theoretical framework that emphasizes the dynamic relationship between human societies and their environments, this approach clarifies how the Nguyen state and its subjects exploited, utilized, and regulated forest resources. Perspectives from landscape and ecological history are employed to interpret forests as both ecological systems and cultural landscapes (Lu, 2025). By analyzing how these sources record forest-related practices and perceptions, the study illuminates transformations in forest landscapes and ecosystems during the nineteenth century, particularly under the influence of state regulation, labor mobilization, and frontier expansion.
The analytical framework integrates three complementary perspectives: (i) environmental history, which situates human-nature interactions within temporal and social contexts; (ii) political ecology, which analyzes how power relations shape access to and control over natural resources; and (iii) resource governance theory, which explains institutional mechanisms for regulation, taxation, and conservation. Combining these perspectives enables a multidimensional understanding of forest management under the Nguyen dynasty—linking ecological transformation with administrative policy and socio-economic impact.
This study is qualitative in nature. Quantitative data on forest cover, biomass, or resource yields during the nineteenth century are unavailable. Nonetheless, future research could incorporate Geographic Information Systems (GIS), environmental archaeology, and historical cartography to quantify long-term changes in forest distribution and ecological structure.
The following sections examine in detail the Nguyen dynasty’s forest-related regulations on exploitation, taxation, reclamation, conservation, and frontier defense. Through close textual analysis of these edicts, the study assesses their implementation, effectiveness, and socio-economic implications—thereby reconstructing how the premodern Vietnamese state sought to govern nature as both a resource and a realm.
Results and Discussion
Forest Conditions in Early Nineteenth-Century Vietnam
The descriptions of forests in the Nguyen Dynasty Official State Histories (NDOSH) reflect not a neutral environmental survey but the administrative gaze of the Nguyen state. Their emphasis on timber quality, tribute value, and provincial capacities reveals a bureaucratic logic oriented toward fiscal extraction, infrastructure building, and frontier security. Although these records contain rich ecological detail, they remain fundamentally administrative documents—produced to monitor resources, regulate obligations, and standardize provincial reporting rather than to catalogue biodiversity. Even so, they make it possible to reconstruct general patterns in the distribution and exploitation of forests under the Nguyen dynasty (Table 1).
In the section devoted to Thua Thien prefecture, the Comprehensive Encyclopaedia lists roughly thirty-five timber types and more than sixty tree species (NDOSH, 2006). In provinces such as Thanh Hoa, Nghe An, and Quang Nam, cinnamon was regarded as the most valuable forest product, prized for its fragrance, medicinal uses, and symbolic association with prosperity. The leaves of the cinnamon tree were believed to cure edema, and its cultural significance was immortalized in imperial iconography: in 1836 (the seventeenth year of Minh Mang’s reign), cinnamon was engraved on one of the Nine Dynastic Urns (Cuu Dinh) in the Imperial Citadel of Hue (NDOSH, 2006). This gesture illustrates how the Nguyen court perceived flora and forest wealth not merely as economic assets but as integral elements of the state’s moral and cosmological order.
In the northern provinces, the Encyclopaedia describes abundant forests yielding diverse and valuable timbers and forest products. Even in the six provinces of Cochinchina (Nam Ky), where plains and river networks dominated the landscape, substantial tracts of woodland remained, supplying both the court and local populations with timber and other forest goods. Such evidence suggests that despite demographic expansion and agricultural reclamation, Vietnam in the early nineteenth century still retained significant forest cover.
While the Comprehensive Encyclopaedia provides a rich catalogue of forest species and products, it represents the worldview of court historiographers rather than empirical observation. Its emphasis lies on the fiscal, symbolic, and utilitarian dimensions of forests—sources of tribute, shipbuilding materials, and royal prosperity—rather than ecological conditions. This descriptive bias mirrors the administrative logic of the Nguyen state, which viewed forests primarily as strategic and economic domains to be governed rather than ecosystems requiring conservation.
Regional variation recorded in Table 1 reveals a distinct spatial pattern. Valuable timbers and forest products were concentrated in the northern and central provinces—areas long incorporated into the imperial heartland—whereas the southern plains, with thinner forest cover, reflected frontier dynamics shaped by settlement, migration, and state-building. Forest abundance, therefore, depended less on natural endowment than on political geography and demographic movement.
From a political-ecology perspective, these records underscore that forests under the Nguyen dynasty were not passive environmental backdrops but dynamic political landscapes. Their richness and depletion alike were consequences of governance, taxation, and social organization. Forests functioned simultaneously as fiscal resources, strategic frontiers, and arenas of negotiation between local communities, provincial officials, and the imperial court. The balance between economic demand and ecological sustainability remained fragile, revealing both the reach and the limits of state authority in a pre-industrial polity.
The Comprehensive Encyclopaedia further indicates that early nineteenth-century Vietnam possessed a rich and diverse forest ecosystem concentrated mainly in the northern and central provinces. These forests supplied the royal court with timber for shipbuilding, palaces, temples, and public works, as well as materials for trade. They yielded not only valuable hardwoods but also a wide range of plant and animal products—resins, spices, varnishes, aromatic woods, and game—demonstrating the essential role forests played in the social and economic life of the Nguyen realm.
The official records, however, reveal little about the social dimensions of forest use—how extraction was organized, who benefited, or how labor and taxation shaped access. This absence reflects the priorities of Nguyen historiography, which privileged fiscal and strategic concerns over environmental or social dynamics.
Beyond Vietnamese sources, Western observers who visited the region during the nineteenth century also remarked on the abundance and commercial value of its forest resources, particularly species traded with China and other parts of Asia. One of the earliest and most detailed accounts comes from John White, an American naval officer aboard the brig Franklin, which visited Saigon in 1819. Describing the wealth of Cochinchina, White noted that its forests produced fragrant woods such as eaglewood, rosewood, and sappan, as well as ironwood, varnish trees, dammar, gamboge, bamboo, and rattan—along with timbers used for dyeing, construction, and artisanal crafts. He also listed an extensive array of forest and animal products: cinnamon, honey, wax, pelts, areca nut, betel, tobacco, cotton, raw silk, sugar, musk, cassia, cardamom, pepper, indigo, sago, ivory, gold dust, rhinoceros horn, and six varieties of rice (White, 1824).
By the mid-nineteenth century, as the French advanced into Vietnam, the country’s forests—especially their potential for naval shipbuilding—had attracted significant colonial attention. As McElwee (2016) notes, French administrators viewed these forests as both valuable and mismanaged. Clovis Thorel, a naval physician and botanist, offered a critical assessment of forestry practices in Indochina. He argued that inhabitants—Vietnamese and Chinese alike—relied on destructive methods: burning forests to cultivate rice, maize, or cotton; clearing them to ease travel or hunting; or setting fires for diversion. According to Thorel, the widespread use of fire devastated nearly half of Indochina’s forested land annually, even on mountain slopes. Such practices, he observed, contrasted sharply with temperate forestry, resulting in severe degradation and leaving only remote areas with pristine forest (Thorel, 2001).
Taken together, Vietnamese and Western accounts present a paradoxical image of abundance and decline. While Nguyen sources celebrated forest wealth as a marker of prosperity and royal virtue, European observers emphasized waste and ecological loss. Reconciling these perspectives suggests that by the mid-nineteenth century, localized deforestation had already occurred—especially near densely populated deltas and coastal plains—while upland forests remained relatively intact, sustained by monsoon-driven regeneration and limited extraction.
This dual image—of wealth and vulnerability—provides essential context for understanding the Nguyen dynasty’s evolving forest policies. The apparent abundance of natural forests prompted the formulation of regulations, taxes, and conservation measures that sought to transform the empire’s ecological resources into a structured regime of management and control. The following section examines these institutional responses in detail, tracing how the state attempted to reconcile economic utility with environmental restraint.
Regulations on Forest Governance in Vietnam under the Nguyen Dynasty
With its extensive and diverse forest resources—crucial for both socio-economic development and national defense—the management of forests under the Nguyen dynasty was a matter of central importance. Yet until the French conquest in the mid-nineteenth century, no formal legal code specifically addressed forest management or conservation. Even so, the chronicles compiled by royal historiographers preserve valuable evidence of how the court governed, exploited, and protected forested lands (Fig. 1).
Although no specialized forestry code existed, the Nguyen system nonetheless embodied an implicit regime of governance. The chronicles reveal a blend of command-based control, moral regulation, and fiscal extraction—characteristic features of premodern environmental administration in Southeast Asia. Forests were regarded simultaneously as economic and moral resources: vital to state-building, military security, and the cultivation of imperial virtue. Through forest-related decrees, the court articulated expectations of loyalty, labor, and tribute from both officials and local communities.
Such an implicit order reflects what scholars describe as “governance without codification,” in which administrative practice, rather than statutory law, served as the primary vehicle of regulation. This form of practice-based governance was shaped by the decentralized nature of imperial authority in premodern Vietnam. Royal edicts, bureaucratic instructions, and moral injunctions collectively constituted a functional—though uncodified—framework for managing forest resources. Through a web of administrative mechanisms, including fiscal incentives, ritual prohibitions, and disciplinary sanctions, the Nguyen state sustained resource extraction while asserting sovereignty over forested landscapes.
From a comparative perspective, this “governance without codification” parallels the environmental administration of other Southeast Asian polities, where control over natural resources emerged less from formal legal codes than from the moral economy of kingship. The Nguyen dynasty’s pragmatic mode of environmental governance reconciled state extraction with moral obligation, administrative flexibility, and the broader ideological foundations of imperial rule.
Regulations on the Exploitation of Timber and Forest Products
The chronicles contain numerous entries showing that the Nguyen court routinely dispatched officials to procure timber and other forest products for state use. In the fifth month of 1835, for example, Guard Supervisor Nguyen Trong Tinh led six clerks into forested areas to acquire timber planks (NDOSH, 2007, vol. 4, p. 645). Likewise, in 1836, Guard Leader Vu was assigned to purchase timber for government projects (NDOSH, 2007). To stimulate productivity, the court established explicit reward schemes. In 1819, workers in Quang Tri received 7 tien for an ironwood plank 11 feet long and 4 inches wide, 6 tien for a 10-foot plank, and 5 tien for a 9-foot plank; rosewood of similar dimensions earned an additional half-coin (NDOSH, 2002).
Incentives were coupled with punishments. In 1809, Guard Commander Van Nguyen was convicted of sending soldiers to exploit timber illegally and harass villagers; he was flogged 70 times and dismissed from office (NDOSH, 2002). Conversely, some citizens voluntarily supported state timber initiatives. In 1839, Ngo Viet Duc of Huong Tra discovered a rich timber source at Thach Han and petitioned the Ministry of Public Works to mobilize labor there (NDOSH, 2007). These cases illustrate a bureaucratic chain linking royal decrees, ministries, and local laborers. The combination of rewards and sanctions reflects an early form of bureaucratic management grounded in both moral regulation and fiscal logic.
Forest exploitation served multiple state purposes, particularly construction and shipbuilding. In 1804, the court ordered provinces from Quang Duc to Nghe An to supply timber for newly planned warehouses (NDOSH, 2002). In 1839, Acting Commander Tran Huu Le led 1,500 soldiers into the forests to collect timber for pavilions and towers (NDOSH, 2007). Shipbuilding was especially significant: in 1805, workers in Quang Tri gathered timber for a hai đao vessel and received monetary and rice rewards (NDOSH, 2002). In 1824, Commander Nguyen Tai Nang supervised the construction of royal boats and mobilized 1,000 border soldiers (NDOSH, 2007). By 1834, three large copper-plated ships—Van Dien, An Duong, and Dinh Duong—were completed under the supervision of Phan Huu Tam and Doan Kim (NDOSH, 2007).
The large-scale mobilization of labor highlights how forest exploitation primarily supported infrastructure, military security, and royal projects rather than private commerce. It demonstrates the state’s infrastructural power: transforming natural landscapes into the material base of sovereignty. Before mechanization, timber extraction depended heavily on human labor and was highly vulnerable to climate. In 1805, extreme heat halted operations (NDOSH, 2002); in 1825, 5,000 soldiers became ill from rain and heat and were released from service (NDOSH, 2007).
The chronicles also record regulations concerning wildlife and mineral resources. In 1815, the court required the annual presentation of wild animals for ancestral rites (NDOSH, 2002). By 1820, this practice was abolished to avoid burdening the population (NDOSH, 2007). In 1831, a new edict mandated that animals for major rituals be sourced only from the royal park Loc Uyen; hunting for ritual use was permitted solely by imperial command (NDOSH, 2007).
In 1836, the court issued a comprehensive annual regulation on forest and marine products for the southern provinces (Table 2). Each locality was assigned specific tribute items according to its ecological characteristics (NDOSH, 2007).
Thirty-seven years later, in 1873, the Ministry of Revenue introduced a new regulation targeting high-value forest and wildlife products—elephant tusks and rhinoceros horns (Table 3). These items were classified as tribute commodities and subject to strict quality requirements, based on size-based grading categories (Table 4). Prices were standardized at 3 quan per can (≈ 0.6 kg) for tusks and 50 quan per can for horns, with provincial adjustments in Binh Thuan (NDOSH, 2007). Despite the regulation’s long-term intent, several provinces eventually fell behind in their tribute obligations.
Taken together, these records show that forest exploitation under the Nguyen dynasty was never purely economic. It was inseparable from political authority, ritual obligations, and fiscal control. The monarchy’s management of timber, wildlife, and forest products balanced state necessity with moral governance—forming a flexible and pragmatic system that reconciled extraction with ethical responsibility. This model represented a distinctly Vietnamese mode of environmental governance, rooted in administrative rationality and the moral economy of Confucian statecraft.
Regulations on the Taxation of Forestry
Recognizing the economic value of timber and forest products, the Nguyen court imposed levies on both categories. In the twelfth month of 1846, patrol stations in Thua Thien, Quang Tri, Binh Thuan, Phu Yen, and Bien Hoa collected a one-tenth tax on goods purchased from the Khmer population or extracted from nearby forests, with payment permitted either in kind or in cash (NDOSH, 2007).
The taxation system thus served both economic and disciplinary functions. Levies generated state revenue while extending administrative oversight into upland and frontier regions. By taxing forest goods gathered by Khmer and other highland groups, the state incorporated peripheral populations into tributary relations mediated through commercial exchange.
Timber taxation was closely monitored. In the first month of 1847, Acting Governor-General of An-Tinh Dang Duc Thiem submitted a petition regarding excessive requisitions of ironwood (go lim). He reported that the districts of Quy Chau, Tuong Duong, and Nghia Duong were already burdened by multiple obligations, including taxes on cinnamon and ironwood, levies on beeswax and coarse cloth, military service, and the poll tax. With a shortage of male labor and forests nearing depletion, he proposed redistributing the tax burden to neighboring districts—Luong Son, Thanh Chuong, Quynh Chau, Huong Son, and La Son— and assigning river communities (van, administrative boatmen’s units) to assist with transport using tax funds for wages. The king rejected the proposal, emphasizing that timber procurement was conducted at official purchase prices rather than as forced extraction, and that existing obligations could not be offset. Timber collection, he insisted, was a duty of any locality possessing forest resources; shifting responsibilities would constitute evasion (NDOSH, 2007).
Beyond taxation, the chronicles record numerous exemptions and reductions in timber levies and corvée labor—granted largely for hardship relief or administrative pragmatism rather than environmental protection. As early as the third month of 1802, the court reduced by one-third the tax on am son specialists skilled in locating agarwood (NDOSH, 2002). In 1804, localities that annually presented valuable forest and marine products received full tax exemptions (NDOSH, 2002). The following year, Nghe An was allowed to offset arrears in ironwood taxes with rosewood and obtained a 40 percent reduction in the paddle-tax (NDOSH, 2002). That same year, a rattan, water, and charcoal tax imposed on the Dong Sach Tu team in Quang Binh was abolished after its members fled conscription; the king approved the petition (NDOSH, 2002).
Such remissions reveal the flexibility of the Nguyen fiscal apparatus. They aimed to reduce unrest, encourage labor, or accommodate local conditions rather than promote conservation. These pragmatic adjustments enabled continued extraction without exhausting human or natural resources.
In 1805, workers in Quang Duc and Quang Tri who had paid taxes in timber were exempt from additional corvée duties. Able-bodied men were required to supply two trees each (≈ 10 m long, 8 inches in diameter), while the elderly or infirm owed half this amount (NDOSH, 2002). In 1807, lam cong workers in Quang Tri received a one-year exemption from timber taxes (NDOSH, 2002).
Exemptions continued into later reigns. In 1820, the Ministry of Public Works sought to collect timber taxes in advance from Quang Tri, but the king rejected the proposal, citing an earlier decree remitting taxes for that year. He remarked that the ink on the edict had hardly dried and questioned how public trust could be maintained if the government reversed itself. Should timber be insufficient, he added, state funds ought to compensate the shortfall (NDOSH, 2007). In 1821, the poll tax was waived for two forest-worker teams in Quang Tri (NDOSH, 2007). In 1833, Nghe An—struggling with ironwood-tax arrears—received a 20 percent reduction for the current year and full cancellation of earlier debts (NDOSH, 2007). Later, in 1857, new taxes were levied on reclaimed farmland in Son Tay, but exemptions were granted to dense forests, rocky uplands, and landslide-prone areas unsuited to cultivation (NDOSH, 2007).
Taken together, these measures show that Nguyen forest taxation was not a fixed legal code but a negotiated process balancing state objectives, local compliance, and environmental constraints. The result was a form of pragmatic environmental governance in which regulation, taxation, exemption, and moral authority coexisted in shifting equilibrium—simultaneously sustaining and straining Vietnam’s forest frontiers.
Regulations on the Reclamation of Dense Forests and the Control of Wild Animals
Although vast, dense, and uncultivated forests yielded significant economic returns in timber and rare forest products, they also posed serious risks—including miasmatic disease, the concealment of bandits, and attacks by wild animals that threatened nearby inhabitants. Consequently, forest clearance and wildlife control became central concerns of Nguyen state governance. The chronicles record numerous edicts addressing both land reclamation and the regulation of wild animals.
Regarding forest clearance, several entries note that dense forests and rugged terrain impeded military operations and public safety. In the sixth month of 1812, in Quang Ngai, mountain roads had become impassable while thick forests sheltered bandits; the court ordered Phan Tien Hoang to mobilize 300 villagers to reopen the routes (NDOSH, 2002). Likewise, in the third month of 1837, after learning that runoff from upland forests in Ninh Binh fouled streams and caused malaria among officials and soldiers, King Minh Mang instructed provincial authorities to provide water-storage jars and ordered that stream water be consumed only two to three days after rainfall (NDOSH, 2007). These measures show that forest clearance was treated not merely as an economic undertaking but also as a public-health and security strategy—a form of “geopolitical hygiene” designed to domesticate the landscape for imperial order.
Forests were also cleared to expand arable land and establish new settlements. In the ninth month of 1838, the Ministry of War directed guard units to clear land at the foot of the Truc Lam and Thach Han mountains for cultivation, rewarding workers one quan per truong of reclaimed land (NDOSH, 2007). Similarly, in the sixth month of 1857, Tonkin officials were ordered to survey plains, forests, and coastal areas; all unused land suitable for cultivation was designated as state farms (so don dien). Soldiers, prisoners, and convicts (with shackles removed) were resettled and organized under appointed officers to oversee cultivation (NDOSH, 2007). These farms transformed wilderness into productive space through military and penal labor—projecting sovereignty into frontier zones and blurring the boundary between punishment and colonization.
To improve travel safety, in the third month of 1859 the king ordered provinces along the route from Khanh Hoa southward to recruit local laborers to build roadside shelters for food and rest. Workers received 15–20 quan per house, with repayment waived if the settlements survived three years. Soldiers were tasked with cutting trees and hunting wild animals to secure the roads (NDOSH, 2007). This integration of road building, clearance, and wildlife control illustrates how environmental management was woven into broader infrastructural policy.
Edicts to prevent wild-animal attacks were among the most frequent. In the intercalary ninth month of 1832, the court ordered relay stations on dangerous routes in Phu Yen, Binh Hoa, and Binh Thuan to keep five bird guns (dieu sang), powder, and fifty rounds of ammunition; couriers were required to carry one or two guns and fire upon sighting wild beasts (NDOSH, 2007). In the fourth month of 1833, from Phu Yen southward to Ha Tien, the king instructed provinces to select skilled marksmen among soldiers and civilians, equipping them with firearms and powder, and to reward tiger kills (NDOSH, 2007). In the ninth month of 1836, Khanh Hoa hired laborers to clear roadsides; hunters were issued arms, surrendering elephant tusks and rhinoceros horns but keeping other products (NDOSH, 2007). This hybrid system—licensed hunting combined with mandatory tribute—transformed wildlife into a taxable imperial resource.
In the twelfth month of 1837, the court standardized rewards for capturing wild animals and distributed state weapons (bird guns, small cannons, gunpowder) to relay stations from Hue to Cochinchina. Rewards were calibrated by species and size (Table 5).
By 1839, a new proclamation required all localities from Quang Binh southward to maintain firearms and gunpowder for hunting. Officials were held accountable for safety, and campaigns had fixed deadlines—one month for remote provinces and fifteen to twenty days for nearer ones. Reports listing kills by species were to be submitted for royal review (NDOSH, 2007). Later that year, bounty rates were revised and standardized (see Table 6), and a specialized expeditionary force of thirty marksmen and soldiers was deployed to Binh Dinh, Phu Yen, Binh Thuan, and Khanh Hoa with one hundred rounds each (NDOSH, 2007). Wildlife management thus evolved from localized defense into a state-supervised enterprise grounded in administrative oversight and military discipline.
The chronicles also note localized campaigns. In 1838, reports from Binh Dinh prompted an order for provincial governors and judicial officers to lead or dispatch troops to exterminate tigers, with each kill earning 10 quan (NDOSH, 2007). In 1839, soldiers of the Vong Thanh Guard killed seven tigers in Quang Tri, receiving silver and cash rewards (NDOSH, 2007). In 1840, Deputy Captain Phan Ngoc Luong led 300 troops in Phu Loc district to capture a tiger, receiving 30 quan (NDOSH, 2007). That same year, the Khanh Hoa surveillance officer Vu Doan Cung petitioned to form a permanent Forest Hunting Unit (Lam xa doi) of fifty men (NDOSH, 2007). By the 1850s, such units signified a gradual institutionalization of environmental security.
Later, in 1857, residents of Binh Thuan and Khanh Hoa suffering repeated tiger attacks received state relief funds to restore livelihood and safety (NDOSH, 2007). Such measures show that, beyond strict control, the court acknowledged humanitarian obligations and sought to balance coercion with compassion.
The chronicles also hint at a moral dimension in the treatment of animals. In 1844, a stele was erected for O Long, the king’s war elephant, honoring its service. The king reflected that elephants, long used in warfare, symbolized harmony between human authority and nature. The Elephant Corps, together with the Navy and the Five Armies, formed the Seven Armies (That quan), maintaining a shrine with regular offerings (NDOSH, 2007). Elephants and other royal animals thus held sacred status within the Nguyen moral cosmos. Their reverent treatment reflected an early ecological ethic rooted in Confucian benevolence and Buddhist compassion—exploitation tempered by reverence.
Taken together, these records reveal how the Nguyen dynasty combined environmental management, fiscal incentives, and moral restraint to govern the forest frontier. Wildlife control was not merely a defensive act but a moral and administrative project that transformed the natural world into both resource and realm.
Construction of Guard Posts and Forts for Forest Protection and the Prevention of Banditry
The vast forests of Vietnam during the Nguyen dynasty not only yielded economic value through timber and forest products but also played vital defensive roles. Mountainous forests often became refuges for bandits and insurgents, while upland zones served as strategic outposts guarding the realm’s frontiers. As a result, the Nguyen court issued numerous decrees for constructing guard posts and forts in forested and mountainous areas to maintain order and suppress banditry.
These records portray forests as securitized landscapes—simultaneously resource zones and arenas of disorder. By viewing uplands as both sources of revenue and threats to stability, the Nguyen state embedded environmental management within a broader project of imperial control. Forest governance thus became part of frontier policy, in which environmental modification and military policing coevolved to extend state presence into marginal terrains.
The earliest recorded case dates to the tenth month of 1812, when the court ordered the construction of Chi Ne fortress (bao) in Thanh Binh. After a survey deemed the upper Thanh Binh region—long a bandit refuge—strategically important, officials proposed Chi Ne commune in Yen Hoa district as the fortress site. The king approved the plan, dispatched an envoy to supervise construction, and assigned Defense Envoys (Phong ngu su) Quach Cong Chuyen and Quach Cong Huynh to command more than 370 men from Lac Tho district to garrison the fort (NDOSH, 2002).
In 1817, noting that the forested districts of Dong Thanh and Quynh Luu (Nghe An) had become havens for bandits, the king ordered the construction of new forts and the stationing of troops (NDOSH, 2002). These fortifications marked the gradual militarization of the landscape—linking garrisons, roads, and cleared forest corridors. Clearance enabled patrols, and patrols secured clearings—a cyclical process typical of premodern Southeast Asian statecraft.
In 1822, recurrent banditry in Nong Cong district, Thanh Hoa, prompted the establishment of two security outposts in the forested highlands of An Nam commune (NDOSH, 2007). Later, in 1867, the court allocated additional gunpowder and ammunition to multiple provinces for defending forested, mountainous, and coastal areas (NDOSH, 2007). These measures reflected a persistent administrative commitment to frontier defense through material reinforcement.
A major shift occurred in the 1870s with the establishment of the Forest Defense Office (Nha Son phong), signaling the institutional convergence of environmental governance and state security.
In 1875, three Forest Defense Offices were founded in Son Tay, Quang Nam, and Ha Noi. In Son Tay, Governor-General Hoang Ta Viem reported that the forested districts of My Luong and Bat Bat sheltered spies and bandits. He proposed creating a Forest Defense Office to supervise reclamation and establish don dien (military-agricultural colonies) under capable commissioners (NDOSH, 2007).
In the same month, another Forest Defense Office was established in Quang Nam. Nguyen Tao, Financial Commissioner of Nam Dinh and a native of Quang Nam, argued that upland areas along the river between Bao Dinh and Phuoc Son contained extensive fertile land. He proposed appointing local leaders, deploying one company of militia (huong binh), pardoning select convicts to settle and cultivate, and recruiting impoverished peasants exempted from corvée labor to expand cultivation (NDOSH, 2007).
These offices embodied dual purposes: to pacify and to cultivate. By combining military oversight, agricultural colonization, and penal reform, they linked the governance of nature with the governance of people. Through this mechanism, the Nguyen court transformed ecological space into administrative territory, extending imperial authority into forested frontiers.
A third office was founded that same year in Ha Noi, based on a memorial by provincial commissioners Tran Binh and Pham Than Duat. They noted that forested areas spanning Ung Hoa, Hoai Yen, and Chuong Duc were fertile yet unsupervised. They proposed placing a Forest Defense Office under the provincial governor and consolidating six hundred tenant farmers into two companies stationed at garrisons for land reclamation. Assistant Commissioner Nguyen Vi also volunteered to recruit additional settlers (NDOSH, 2007).
In 1876, another Forest Defense Office was created in Hung Hoa. Governor Hoang Ta Viem reported that upper districts contained vast forested hills with concealed paths used by bandits. He proposed staffing the office with officers trained in both garrison and reclamation duties and recruiting settlers to cultivate forested zones. Settlement was systematically organized: 50–100 adult male settlers formed a hamlet; 8–10 hamlets formed a village; and each village (≈ 500 people) was entered into administrative registers (NDOSH, 2007).
This structure—hamlets aggregated into registered villages—illustrated the state’s drive to render populations legible and taxable. Forest reclamation thus became a tool of surveillance and governance, transforming shifting livelihoods into fixed, controllable communities.
From early fortresses (bao) to later Forest Defense Offices, the management of forested and mountainous regions remained central to the Nguyen court’s strategic vision. The evolution from isolated strongholds to institutionalized frontier offices demonstrates the dynasty’s intent to integrate security, administration, and agrarian expansion in the highlands.
Viewed comparatively, this represents a pragmatic model of frontier governance—fusing security, agrarianization, and environmental modification into a negotiated landscape of forts, clearings, and settlements that sustained imperial authority across the forested frontiers of nineteenth-century Vietnam.
Prevention of Forest Exploitation and Promotion of Forest Conservation
Recognizing the strategic and economic importance of forests, the Nguyen court issued a series of decrees to prevent overexploitation and promote forest protection. In June 1840, the king warned the Ministry of Public Works that excessive logging had severely depleted local forests. He emphasized that mountain trees required 30–50 years to mature, and that unrestrained felling would hinder regeneration while timber demand and tax obligations continued to rise. Consequently, he ordered that timber be harvested only under official authorization (NDOSH, 2007).
This edict reflected an early principle of sustainable resource management: a pragmatic attempt to balance construction and shipbuilding needs against the natural rhythms of forest regrowth. Conservation here was strategic rather than moral—an administrative mechanism to safeguard long-term resource supply.
The Nguyen state thus viewed forests not merely as extractive assets but as renewable resources requiring regulation. Aware that valuable hardwoods could take decades or even a century to mature, the court understood that reckless felling threatened both economic and strategic interests. The 1840 decree therefore represents an embryonic form of ecological governance grounded in administrative rationality rather than modern environmentalism.
Large-scale logging was monopolized by the royal court, which simultaneously prohibited private timber trade. In February 1831, an edict banned commoners from trading ironwood (go lim) in any form. Penalties were scaled: under 0.04 kg incurred 100 cane strokes; 0.04–0.23 kg added one month in the cangue; 0.23–0.38 kg carried three years of penal servitude; and above 0.38 kg resulted in exile with military conscription. Confiscated timber was appropriated for state use, and forfeited property was divided evenly between the informer and the state.
Accountability extended beyond offenders. Neighbors or headmen who concealed violations faced 100 strokes, while complicit officials were punished as accomplices. District magistrates who failed to enforce the decree were subject to disciplinary review. Timber already in private possession had to be surrendered at official valuation; concealment was treated as illicit trade. Temples built before the decree were exempt, but officials exploiting the regulation for extortion were punished under fraud statutes (NDOSH, 2007).
In December 1832, the court likewise prohibited private trade in táu timber (Vatica spp.), applying identical penalties. Prior purchasers were required to surrender the wood for compensation, while timber used legitimately before the edict remained exempt. Officials misusing the law faced punishment for coercion or deceit (NDOSH, 2007).
Together, these decrees established a regime of command-monopoly governance: coercive enforcement to ensure compliance, balanced by state purchase to maintain legitimacy. By criminalizing private trade while compensating voluntary surrender, the Nguyen court centralized extraction within official channels—transforming timber into both a strategic material and a taxable commodity.
Illegal logging was subject to retroactive prosecution. In March 1833, Governor-General Nguyen Van Que of An-Bien reported that subordinates of Le Van Duyet—Commandant Ho Van Trieu and Deputy Commandants Nguyen Van Bot and Nguyen Huu Khoi—had illegally harvested timber the previous year, sold it to Qing traders, and used it to build private boats (NDOSH, 2007). The prosecution underscored the court’s determination to discipline regional elites and reaffirm imperial authority. Forest regulation thus operated not only as resource control but also as political accountability across administrative hierarchies.
The Nguyen dynasty also protected sacred forests surrounding royal tombs (son lang). In November 1816, strict prohibitions delineated tomb boundaries with stone markers. Within these zones, cutting trees, gathering firewood, grazing livestock, or lighting fires was forbidden; outsiders were barred from entry, and passing officials were required to dismount and lower umbrellas as a gesture of reverence (NDOSH, 2002). These sacred precincts effectively created ritual forest buffers that doubled as conservation zones— “sacred groves” where environmental restraint embodied moral piety and reinforced dynastic legitimacy.
Forest fires also received administrative attention. In May 1823, a blaze outside a royal-tomb boundary spread to Ngoc Duong Mountain, burning several hundred pines. Remarkably, the trees regenerated within months. Following the fire, Commander Ton That Dao and other officials organized replanting and strengthened surveillance of the area (NDOSH, 2007). This sequence—fire, assessment, reforestation—constituted an early form of empirical forest management, combining observation with administrative action.
Although ad hoc, such responses anticipated later silvicultural practices. Conservation under the Nguyen dynasty thus emerged as both an ethical and administrative responsibility—anchored in ritual reverence, fiscal logic, and practical governance. Taken together, these measures are summarized in Fig. 2, which highlights the Nguyen court’s multifaceted approach to preventing forest overexploitation and promoting conservation through administrative control, legal prohibition, sacred protection, and restorative practices.
In sum, although the Nguyen dynasty lacked a codified forestry law, it developed a diverse regulatory repertoire to curb overexploitation, prohibit illegal timber trade, protect sacred groves, and respond to forest fires. These measures collectively reveal an emergent environmental consciousness that integrated economy, defense, and moral order.
Taken together, these decrees exemplify a pragmatic mode of environmental governance—an assemblage of prohibitions, monopolies, sacred protections, and restorative measures that sought to balance extraction with regeneration. Through such practices, the Nguyen court forged enduring linkages between sovereignty, ritual authority, and the managed life of forests—an early Vietnamese experiment in reconciling utility with restraint.
Conclusion
Forests have long occupied a central position in Vietnamese history, shaping ecological systems, livelihoods, and cultural imagination. Ecologically, they served as the “green lungs” of the environment; economically, they generated timber, non-timber products, and tax revenues; and strategically, they functioned as defensive frontiers. Their symbolic and moral significance endures in the proverb “forests are gold” and in the myth of Lady Au Co, who led her children to the mountains to establish Van Lang—the earliest polity of the Lac Viet.
During the Nguyen dynasty (1802–1883), Vietnam possessed extensive forests from north to south, rich in valuable timber and rare products. Although no codified forestry law or systematic survey existed, chronicles such as the Comprehensive Encyclopaedia of the Great South provide qualitative evidence on forest types, resources, and local classifications. The royal court issued numerous regulations on extraction, taxation, clearance, and frontier defense, while simultaneously promulgating conservation measures such as bans on unauthorized logging and reforestation after fires. These actions reveal a dual logic of governance: the integration of resource extraction for fiscal and strategic purposes with an emerging awareness of ecological sustainability—an early expression of what political ecologists describe as “state-managed nature.”
Viewed through the lens of environmental history, Nguyen forest governance embodied a dynamic interplay between human agency, institutional authority, and ecological constraints. Pragmatic regulation of timber and forest labor reflected both the assertion of state power and the moral imperative to preserve social and cosmic order. Forest management thus operated as a form of moral ecology—linking governance, ritual, and stewardship—and the forest itself became a political and ethical landscape in which legitimacy and sustainability were co-produced.
The historical record is largely qualitative rather than quantitative, consistent with premodern Vietnamese historiography, which privileged synthesis over enumeration. The absence of numerical data—such as forest cover or timber inventories—limits precise environmental assessment; such metrics appeared only in the late nineteenth century under French colonial administration. Likewise, the chronicles seldom discuss the social impacts of forest exploitation on local communities. These gaps underscore the potential of interdisciplinary approaches—combining textual analysis with GIS-based spatial reconstruction and environmental archaeology—to bridge historical and ecological evidence.
Comparatively, the Nguyen dynasty’s forest regime—rooted in moral regulation, selective taxation, and localized enforcement—differed from both the commercialized extraction of the Le-Trinh administration in the Northern Realm (Dang Ngooi) and the technocratic forestry apparatus later introduced under French Indochina. When contrasted with the Qing dynasty’s blend of ritual protection and utilitarian forestry, Vietnam’s experience reveals both convergence in moral environmentalism and divergence in bureaucratic sophistication.
By situating the Nguyen dynasty within broader debates in Southeast Asian and global environmental history, this study highlights how early modern states negotiated the relationship between sovereignty, ecology, and morality. It demonstrates that premodern forest governance was not merely extractive but constitutive of political order and cultural identity. In this respect, the Nguyen dynasty’s environmental governance offers enduring insights into Vietnam’s long tradition of reconciling state developmental imperatives with ecological sustainability.
