Examining spatial and social characteristics of customary trees owned by villagers on public forestlands in Jharkhand, India

Tree ownership is typically tied to land ownership in many societies worldwide. Still, in India, tribal communities have customary ownership over trees in public forestlands, raising questions about what those trees are, where they are located, their characteristics, and whether socioeconomic factors influence their distribution and density. To address these questions, we conducted household interviews and a Global Positioning System (GPS) mapping in Sahritola, a village in the State of Jharkhand, India. We employed Kruskal Wallis, Spearman correlation, and Moran's Index to analyze the collected data. The villagers have been protecting and managing over 18,000 trees in public forestlands, including species such as asan (Terminalia tomentosa), sal (Shorea robusta), and mahua (Madhuca longifolia). Over 80 % of those trees are under individual ownership, while around 20 % are under shared ownership. Additionally, over 60 % of households owned between 100 and 500 trees. Customarily-owned tree species sharing similar characteristics (e.g., height, crown width, and diameter-at-breast-height) tend to cluster together. The number of customarily owned trees is influenced by their economic value and socioeconomic factors (e.g., religion, forestland, etc.). Additionally, the type of customary ownership (individual or shared) influences the characteristics of trees. This study could guide policymakers in potentially developing forest policies that consider the concept of customary tree ownership to promote sustainable management of forest resources in India and beyond.

Towards sustainable management of forest residues in the southern Apennine Mediterranean mountain forests: a scenario-based approach

Key messageManaging forest residues according to the carbon content of the soil helps to minimize the ecological footprint of their removal.ContextIn Mediterranean mountain ecosystems, unsustainable harvesting of wood residues might contribute to land degradation, carbon, and nutrient depletion in forest soils.AimsThis study aimed to assess the amount of forest biomass residues that should be left on-site to minimize the depletion of soil fertility.MethodsWe estimated the availability of biomass residues in the public forest land of the Basilicata region of Southern Italy by collecting stand-scale inventory attributes from forest management plans. Subsequently, we quantified the amount of forest biomass residue released by implementing a scenario-based approach.ResultsApproximately 5800 m3 year−1 of forest residues could be potentially available for bio-based industries at the regional scale within the next 10 years. Such residues mainly belong to broadleaved forest types, having a high variability in their soil organic stock (228.5–705.8 Mg C ha−1) and altitudinally spanning from 400 to 1500 m a.s.l. In these forests, the simulated scenarios displayed a wide range of average harvestable residues from 2.5 to 5.5 m3 ha−1, containing approximately 1.1 to 2.1 Mg ha−1 of organic carbon.ConclusionOur study suggests that forest management plans are a useful source of information to estimate the available forest biomass residues consistently. In southern Mediterranean mountain forests, the management of forest residues according to soil carbon content helps to minimize the environmental impact and increase their sustainability.

Cumulative Severity of Thinned and Unthinned Forests in a Large California Wildfire

Studies pertaining to fire severity in commercially thinned versus unthinned forests are based on a comparison of tree mortality between the two categories. Commercial thinning is widely conducted on public and private forestlands as a fire management approach designed to reduce fire severity and associated tree mortality. However, tree mortality from thinning itself, prior to the occurrence of the wildfire, is generally not taken into account, which leaves a potentially important source of tree loss, with its associated forest carbon loss and carbon emissions, unreported. This study investigated the “cumulative severity” of commercially thinned and unthinned forests in a large 2021 wildfire, the Antelope fire, occurring within mixed-conifer forests on public lands in northern California, USA. Using published data regarding the percent basal area mortality for each commercial thinning unit that burned in the Antelope fire, combined with percent basal area mortality due to the fire itself from post-fire satellite imagery, it was found that commercial thinning was associated with significantly higher overall tree mortality levels (cumulative severity). More research is needed, in other large forest fires, to determine whether the finding, that commercial thinning killed more trees than it prevented from being killed, is common elsewhere.

Long-Term Ecosystem Nutrient Pool Status for Aspen Forest Harvest Simulations on Glacial Till and Sandy Outwash Soils

Sandy outwash and glacial till soils compose large amounts of public forestland due to historically poor agricultural yields. The outwash soils have low fertility, poor nutrient retention and are restricted from whole-tree harvesting (WTH) in some states, whereas the glacial till has medium nutrient retention and fertility, and is unrestricted from WTH. To assess the long-term sustainability of harvesting, a nutrient budget was constructed from field measurements, the National Cooperative Soil Survey (NCSS) database, and literature values for stem-only harvesting (SOH) and WTH at a 45-year rotation length and 11 rotations were simulated. The budgets showed that SOH and WTH recovery years, or the time necessary for the inputs to match outputs through leaching and one harvest, exceeded common rotation lengths for both soil types under all weathering scenarios, and the average WTH reduced the total available rotations by one harvest. The large variation in soil nutrient pools and harvest removals complicated the ability to identify the difference between SOH and WTH early in the model, but differences became apparent with sequential harvests. The recovery years were 2–20 times the 45-year rotation length under all weathering rates. Taken together, models in this study bridge the gap between short- and long-term studies and bring into question the sustainability of WTH and SOH practices on nutrient-poor soils.

Dual Discounting in Renewable Resource Planning under Risk.

Renewable resource planning and management projects entail evaluating economic and ecological criteria in the long term. During the past decade or so, dual discounting--ecological criteria discounted at a smaller rate than that for economic criteria--has been proposed for such projects as an alternative to the prevailing single-discounting scheme, out of theoretical and empirical considerations. We focus on how to apply this principle in planning problems that involve a multitude of risk in the attendant biological-economic system. A stochastic dynamic programming framework is introduced which allows dual discounting rates and finds the optimal decisions (passively) adapting to changes in the system. Furthermore, we show how to evaluate the variances of the criteria in this framework. With a case study of managing public forestlands in the US Pacific Northwestern region for both timber return and habitat preservation for the northern spotted owl (Strix occidentalis caurina), we illustrate the impacts that the dual-discounting scheme has on the trade-off between conflicting management objectives, the optimal planning strategy, the temporal development of the portion of the forestlands suitable for owl habitats, as well as its steady-state expected value and standard deviation.

Laws, Markets, and Local Politics Drive Outcomes of Minnesota’s County Managed Forests

Abstract There are frequently calls to increase local government control over forests in the US. Minnesota’s county forests contain approximately 30% of all local-government-managed forests in the United States. These forests are managed in ways that protect public access while providing a stable timber supply to mills. This happens because of the intersection of law, markets, and local politics. County forests are legally obligated to provide revenue to local tax districts while paying for management from money earned from timber sales. This pushes counties towards managing with the goal of providing a stable revenue stream from their lands, a goal that is supported by local politics in timber-dependent counties. The result is that counties are more production-oriented than other public forestland managers; however, they provide more consistent public access than private forest owners.

Mixed-conifer forest reference conditions for privately owned timberland in the southern Cascade Range.

The overwhelming majority of information on historical forest conditions in western North America comes from public lands, which may provide an incomplete description of historical landscapes. In this study we made use of an archive containing extensive timber survey data collected in the early 1920s from privately owned forestland. These data covered over 50,000ha and effectively represent a 19% sample of the entire area. The historical forest conditions reconstructed from these data fit the classic model of frequent-fire forests: large trees, low density, and pine-dominated. However, unlike other large-scale forest reconstructions, our study area exhibited relatively low overall variability in forest structure and composition across the historical landscape. Despite having low variability, our analyses revealed evidence of biophysical controls on tree density and pine fraction. Annual climatic variables most strongly explained the range in historical tree densities, whereas historical pine fraction was explained by a combination of topographic and climatic variables. Contemporary forest inventory data collected from both public and private lands within the same general area, albeit not a direct remeasurement, revealed substantial increases in tree density and greatly reduced pine fractions relative to historical conditions. Contemporary forests exhibited a far greater range in these conditions than what existed historically. These findings suggest that private forestland managed with multiaged silviculture may be similar to public forestland with respect to departure in forest structure and compositions from that of historical forests. However, there may be differences between management objectives that favor timber production, more typical on private lands, vs. those that favor restoration, increasingly supported on public lands.

Balancing Large-Scale Wildlife Protection and Forest Management Goals with a Game-Theoretic Approach

When adopted, wildlife protection policies in Canadian forests typically cover large areas and affect multiple economic agents working in these landscapes. Such measures are likely to increase the costs of timber for forestry companies operating in the area, which may hinder their acceptance of the policies unless harvesting remains profitable. We propose a bi-level wildlife protection problem that accounts for the profit-maximizing behavior of forestry companies operating in an area subject to protection. We consider the regulator with a wildlife protection mandate and forestry companies licensed to harvest public forest lands. We depict the relationship between the regulator and forestry companies as a leader-follower Stackelberg game. The leader sets the protected area target for each license area and the followers adjust their strategies to maximize payoffs while meeting the protection target set by the leader. The leader’s objective is to maximize the area-wide protection of spatially contiguous habitat while accounting for the followers’ profit-maximizing behavior. We apply the approach to investigate habitat protection policies for woodland caribou in the Churchill range, Ontario, Canada. We compare the game-theoretic solutions with solutions that do not consider the forest companies’ objectives and also with solutions equalizing the revenue losses among the companies.

Policies for establishing hybrid poplar plantations on private and public lands in western Canada for bioethanol feedstock: a forest-level financial analysis

A forest-level model is developed that estimates how policies towards hybrid poplar plantations on private and public land impact harvest levels and values for producing biofuel feedstock. We simulate three policy changes: (i) permitting an increase in harvest levels on public land as a result of establishing hybrid poplar plantations on private land; (ii) permitting the establishment of hybrid poplar plantations on public land; and (iii) including forest carbon emission offsets in the net benefits realized by the forest operator. We are interested in whether the increase in harvest created by the policies might be enough to supply a biorefinery, and how the value of the operation changes. Our results suggest that jointly managing public and private lands under sustained yield can increase harvest by between 7% and 93%, and increase the value of the operation by between 39% and 263%. Results also suggest that hybrid poplar plantations could enable a leaseholder of one million hectares of public forestland to initiate an allowable cut effect and thereby increase harvest enough to supply a new biorefinery, in addition to its existing pulp mill. Carbon offsets further increase the value of the forest, although harvest begins to decline at high carbon prices.

Dynamics of Large Corporate Forestland Ownerships in the United States

Abstract Ownership of forestland in the United States has changed in recent decades, including the proliferation of timber investment management organizations (TIMOs) and real estate investment trusts (REITs), with the potential to alter forest management and timber supply. This article quantifies forest ownership transitions among ownership categories between 2007 and 2017 and investigates how and why large corporate ownerships own and manage their forestlands. Ownership transitions were determined from refined USDA Forest Service, Forest Inventory and Analysis data; we also conducted a survey of large corporate forestland ownerships. Corporate forestland acreage increased between 2007 and 2017, while family and public forestland decreased. Large corporate landowners report multidimensional, financially focused land management, although industry, timber investment management organizations, real estate investment trusts, and other owners report some different motivations and income streams. This work provides a baseline to track future ownership transitions and the behaviors of large corporate forestland owners.

Reshaping forest management in Australia to provide nature-based solutions to global challenges

ABSTRACT It is time to move beyond the era of conflict and develop a new shared vision for the management of Australia’s public forests. We need more holistic approaches that encompass all forest values across the landscape, rather than the current approach of dividing public forest management up across different government agencies. More collaborative approaches will be required to galvanise the resources, skills and knowledge that enables this shift in shared governance. Recent bushfires in Australia have heightened concerns that the management of public forest lands has largely failed to ensure the health of forest ecosystems, build resilience, and secure a promised balance between economic, social and environmental values. Investment in efforts to adapt forest management to address climate change has been limited; and empowering and increasing the role of Indigenous Australians in forest management could be significantly improved. Furthermore, the COVID-19 pandemic has highlighted the need to improve the resilience of regional communities to major shocks and stresses caused by factors that encompass market dynamics, supply-chain disruptions and natural disasters. Three key strategies are proposed to strengthen forest management in Australia: first, establishing new shared governance models that bring together government agencies with Indigenous Australians and actors from the private sector and civil society; second, extending active and adaptive management across forest landscapes that builds resilience in our forests, local communities and society; and third, integrating traditional knowledge with scientific evidence and innovative technologies to enhance forest management for improved resilience and other outcomes.

The potential of agroforestry concessions to stabilize Amazonian forest frontiers: a case study on the economic and environmental robustness of informally settled small-scale cocoa farmers in Peru

Agroforestry Concessions, foreseen by the new Peruvian Forest Law, anticipate integrating thousands of small-scale farmers encroached on public forest land into the formal economy, to strengthen local livelihoods, stimulate land restoration, and halt deforestation. But, there are contrasting opinions regarding the potential of agroforestry and land tenure security to create economically and environmentally robust livelihoods. To better understand the relevance of this potential, this study analyses the economic and environmental robustness of 118 informally settled small-scale cocoa farmers in three districts in the Peruvian Amazon. The study shows that the vast majority of these farmers faced serious obstacles to overcome. Less than 20 % of the households have managed to establish economically robust livelihoods on a robust natural production basis. Farm size, specialization in cocoa, and participation in associations positively influenced the economic performance of the households but had little effect on the quality of natural resource management and on the capacity to conserve forests. To harness the potential of cocoa farming requires long-term support well adapted to local specificities. The legal recognition of sustainable land-use practices on public forest land is a meaningful step. To effectively address deforestation, however, requires broader integrated approaches that go far beyond the promotion of sustainable land-uses.

From deforestation to afforestation: Effect of slopeland use policies on land use/cover change in Taiwan

Understanding the effects of public policy on land-use/cover change is an important step for improving management strategies and policy. Few studies have constructed scholarly evidence on the effects of policy on slopeland change from deforestation to afforestation. This research adopted a land-use change analysis using GIS to evaluate the influence of the inducted slopeland-use policy on the slopeland-use change in Veterans Affairs Council (VAC) farms. Taiwan’s slopeland-use policies included Veteran Agricultural Reclamation Policy (VARP) (1955−1988), Farmland Release Policy (FRP) (1989–2004), and National Land Restoration Policy (NLRP) (2005−2015). The results showed that VARP quickly changed 21.15 % forestland into farmland to obtain economic benefits and cause potential negative environmental impacts through veterans’ migration. The potential labor and population migration should be considered on public policy decision-making for avoiding forestland-use change. The 7.36 % public farmland and 0.72 % private farmland changed into forestland in FRP. The 27.33 % public farmland and 3.53 % private farmland changed into forestland in NLRP. FRP changed public farmland into private farmland and obstructed afforestation. NLRP had a strong regulatory power for afforestation and potential ecological benefits with farmland reduction in public land. The effect of restoration policy was obstructed by private farmland. The potential land privatization should be taken into account for the efficacy of afforestation and conservation policy. This study also found critical information. The ecotourism and non-ecotourism strategies produced different slopeland-use changes and potential impacts. Ecotourism strategy increased 29.19 % and 9.72 % public forestland in two farm cases and reduced potential negative environmental impacts. Non-ecotourism strategy increased 9.81 % construction land and 2.05 % road on private land and reflected potential negative environmental impacts. Ecotourism strategy was suggested to be a suitable method to balance ecology and economy for sustainable development.

Exploring the process of, and potential demand for, water resource land acquisition in Japan

This study focused on the suspected conflict between Japanese public opinion and forest land acquisition by foreign investors in Japan’s water source areas. To establish whether the state of public anxiety and the regulatory efforts to address it corresponds with investors’ opinions and intentions, the study investigated the interest of investors from Taiwan and Hong Kong in acquiring land in these water source areas. An analysis of 618 responses, obtained through an online questionnaire, revealed the following: (1) recent land acquisition by foreign economic entities is concentrated on flat areas, rather than water source areas. (2) Almost all investors that acquired land were conscious of the need to maintain harmonious relations with local communities. (3) Land acquisition in water source areas is expected to continue in future, but the purpose is neither to hold assets without a clear purpose nor to resell them for profit, nor to develop water resources. (4) Investors had no intention of undermining the concerns of local residents. In future, developing an effective management plan for the water source region will depend upon creating a system of governance that allows for the sharing of consciousness and the exchange of information by local resident, cities, prefectures, and the country as a whole. Above all, it should have an accurate factual basis.

Lawless land in no man’s land: The undesignated public forests in the Brazilian Amazon

The Brazilian Amazon has 49.8 million hectares (Mha) of public forestlands not allocated by the federal or state governments to a specific tenure status: the so called undesignated public forests (UPF). Historically, these public forests have been vulnerable to land grabbers and land speculation. Here, we highlighted the imminent threat in UPF by quantifying their accumulated deforestation, all of which is illegal, for the period 1997–2018 and the potential illegal occupation. Based on the available government database, we found that 2.6 Mha of UPF had already been deforested by 2018 resulting in an emission of 1.2 billion tons of CO2 (Gt CO2). The accumulated deforestation was 5.4 times higher in federal UPF than in state UPF. Moreover, a total of 11.6 Mha of UPF have already been illegally registered as “private property” in the Brazilian Environmental Rural Registry (CAR), 70 % of these areas located in state UPF. If legalized as private proprieties, the carbon emissions resulting from additional deforestation will be roughly between 1.2 and 3.0 Gt CO2. The seriousness and precariousness of protection of Brazilian Amazon UPF, the rapid conversion of forests outside these areas and increased flexibility in land policies - calls for the immediate designation of these areas to some form of conservation, as to avoid irreparable damage to the world's largest rainforest.

Forest use strategies and their determinants among rural households in the Miombo woodlands of the Copperbelt Province, Zambia

Forest landscapes in tropical and subtropical areas support the livelihoods of their inhabitants through subsistence use of products, and cash income obtained from the sale of products. Despite its contribution to livelihoods, it remains unclear how forest products play a role in forest use strategies and what affects different forest use strategies, particularly in rural tropical Africa. A better understanding of forest-based livelihood strategies could be an important basis for the design of sustainable development policies. In this study, we use cluster analysis to identify forest use strategies and apply multinomial logistic regression to determine the factors affecting forest use strategy choices using data from 412 households in four sites in the rural Copperbelt province.Results reveal three strategic forest use choices undertaken by households: specialised charcoal sellers (32.3%), forest food and charcoal sellers (18.2%) and pure subsistence-orientated forest users (49.5%). Forest income varied strongly among forest use strategies; specialised charcoal sellers and forest food and charcoal sellers were the most remunerative strategies. We observed higher per capita extraction of firewood and charcoal produced in restricted landscapes compared to non-restricted landscapes. Distances to exclusively owned forestlands, access to permanent roads, restrictions on public forestlands and off-farm incomes were found to determine access to more lucrative forest use strategies. Alternatively, households with relatively older heads and larger sizes are associated with lower income (subsistence) strategies.The results suggest the need for the efficient enforcement of restriction regimes, but also the benefit of understanding forest resource governance. Charcoal production is a more remunerative forest use strategy for rural households and a relatively resource-intensive yet important component of the rural economy. In order to ensure sustainable production, the demand for charcoal should be compatible with Miombo's production capacity. Sustainable production can be achieved by introducing reforestation or coppicing systems that are consistent with the growing demands of Miombo.

Investigating the Impact of Land Parcelization on Forest Composition and Structure in Southeastern Ohio Using Multi-Source Remotely Sensed Data

Forestland parcelization (i.e., a process by which large parcels of forestland ownership are divided into many small parcels) presents an increasing challenge to sustainable forest development in the United States. In Southeastern Ohio, forests also experienced intensive forestland parcelization, where the majority of forest owners own parcels smaller than 10 acres currently. To better understand the impact of forestland parcelization on forest development, this study employed multi-source remotely sensed data and land ownership data in Hocking County, Ohio to examine the relationship between forestland parcel size and forest attributes, including forest composition and structure. Our results show that private forestland parcels are generally smaller than public forestland (the average parcel sizes are 21.5 vs. 275.0 acres). Compared with private lands, public lands have higher values in all forest attributes, including forest coverage, abundance of oak-dominant stands, canopy height and aboveground biomass. A further investigation focusing on private forestland reveals that smaller parcels tend to have smaller forest coverage, less greenness, lower height and aboveground biomass, indicating that forests in smaller parcels may experience more human disturbances than larger parcels. The results also show that logarithmic models can well quantify the non-linear relationship between forest attributes and parcel size in the study area. Our study suggests that forestland parcelization indeed has negative effects on forest development, so it is very important to take appropriate measures to protect forests in small ownership parcels.

Current Status of Forest Health Policy in the United States.

Federal policies related to forestry and forest health (specifically, insects and diseases) have the potential to affect management practices, terms of international and interstate trade, and long-term sustainability and conservation. Our objectives were to review existing federal policies, the role of federal agencies in managing forest health, and guidance for future policy efforts. Since the 1940s, various federal policies relevant to forest health have been established, and several US Department of Agriculture (USDA) agencies have been empowered to assist with prevention, quarantine, detection, management, and control of insects and diseases. Overall, our review showed that relatively few national policies directly address forest health as a stand-alone objective, as most of them are embedded within forestry bills. Federal funding for forest health issues and the number of personnel dedicated to such issues have declined dramatically for some agencies. Concomitantly, native species continue to gain pestiferous status while non-native species continue to establish and cause impacts in the US. To enhance our ability and capacity to deal with current and future threats, concerted efforts are needed to advocate for both resources and stand-alone policy tools that take seriously the complexity of emerging sustainability challenges in both private and public forestlands.

Economic Contributions of the Forest Industry and Forest-based Recreation in Florida in 2016

The state of Florida is half woods, with 26,807 square miles of forestland. Our extensive natural and planted pine and hardwood forests are used for production of a wide variety of wood building materials, consumer paper and packaging products, chemicals, and renewable biomass fuels. In addition to industrial forest-related activity, public forestlands in Florida support a variety of recreational activities, attract a significant number of recreational visitors, and provide many non-marketed environmental or ecosystem services. This 4-page fact sheet written by Christa Dean Court, Alan W Hodges, and Mohammad Rahmani and published by the UF/IFAS Food and Resource Economics Department describes a study that analyzed the economic contributions of the forest industry and forest-based recreation activities to the state of Florida in 2016. http://edis.ifas.ufl.edu/fe1051
