Abstract:

SUMMARYExtractive reserves are conservation units that are concurrently expected to sustain subsistence and cash economies of reserve residents, often through use of non-timber forest products (NTFPs). Brazil nut (Bertholletia excelsa) has been central to many Amazonian reserves and resident livelihoods therein, due to its basin-wide distribution, significance in global markets, and potential for sustainable use and forest conservation. Yet, do the benefits of this and other NTFPs extend to all extractive reserve residents? A livelihood survey, structured interviews, and Brazil nut inventories from 2008 to 2010, randomly sampling the widely dispersed households and corresponding forests across the three regions of Riozinho do Anfrísio Extractive Reserve (RDAER), revealed significant social and ecological heterogeneity among RDAER regions. There were differences in Brazil nut stand access, individual tree characteristics (including crown form and marginally, and fruit production), stand and tree management, multiple household characteristics that shape resident investment and dependence on NTFPs, and the contribution of Brazil nut to forest-based income. If Brazil nut and other NTFPs are to reconcile conservation and development in forest communities, then policies to regulate and promote NTFP use must integrate the socioecological heterogeneity inherent in these forest products and within reserve polygons.

Abstract:

Intensively managed forest plantations occur or are recommended in several Canadian provinces, in Oregon and Washington, in the southern United States and worldwide. Intensively managed plantations help meet increased demands for forest products in these areas. Northwest Ontario also will need increased wood production for increased present and future national and international wood markets. However, a recent Forest Accord for Northwest Ontario has almost doubled the areas reserved for parks and conservation reserves creating a dilemma where increased wood production will be needed from decreased areas of forest land available primarily for timber management. This dilemma can be partially resolved using intensive management for forest plantations established on productive (good site) forest lands. Intensively managed plantations have the potential for producing greatly increased quantity and quality of wood, thus partially resolving present and future wood supply needs. Concentrating wood production on selected good sites in Northwest Ontario also will allow us to dedicate increased areas of forest land to multiple-use management as well as more parks and conservation reserves. Key words: forest land zonation, site-quality evaluation tools, site-specific silviculture, stand and landscape diversity

Abstract:

Protected areas form a quintessential component of the global strategy to perpetuate tropical biodiversity within relatively undisturbed wildlands, but they are becoming increasingly isolated by rapid agricultural encroachment. Here we consider a network of 788 forest protected areas (PAs) in the world’s largest tropical country to examine the degree to which they remain intact, and their responses to multiple biophysical and socioeconomic variables potentially affecting natural habitat loss under varying contexts of rural development. PAs within the complex Brazilian National System of Conservation Units (SNUC) are broken down into two main classes—strictly protected and sustainable use. Collectively, these account for 22.6% of the forest biomes within Brazil’s national territory, primarily within the Amazon and the Atlantic Forest, but are widely variable in size, ecoregional representation, management strategy, and the degree to which they are threatened by human activities both within and outside reserve boundaries. In particular, we examine the variation in habitat conversion rates in both strictly protected and sustainable use reserves as a function of the internal and external human population density, and levels of land-use revenue in adjacent human-dominated landscapes. Our results show that PAs surrounded by heavily settled agro-pastoral landscapes face much greater challenges in retaining their natural vegetation, and that strictly protected areas are considerably less degraded than sustainable use reserves, which can rival levels of habitat degradation within adjacent 10-km buffer areas outside.

Abstract:

Conservation biology is increasingly concerned with preserving interactions among species such as mutualisms in landscapes facing anthropogenic change. We investigated how one kind of mutualism, mixed-species bird flocks, influences the way in which birds respond to different habitat types of varying land-use intensity. We use data from a well-replicated, large-scale study in Sri Lanka and the Western Ghats of India, in which flocks were observed inside forest reserves, in ‘buffer zones' of degraded forest or timber plantations, and in areas of intensive agriculture. We find flocks affected the responses of birds in three ways: (i) species with high propensity to flock were more sensitive to land use; (ii) different flock types, dominated by different flock leaders, varied in their sensitivity to land use and because following species have distinct preferences for leaders, this can have a cascading effect on followers' habitat selection; and (iii) those forest-interior species that remain outside of forests were found more inside flocks than would be expected by chance, as they may use flocks more in suboptimal habitat. We conclude that designing policies to protect flocks and their leading species may be an effective way to conserve multiple bird species in mixed forest and agricultural landscapes.

Abstract:

In the late 1980s the Ugandan Government decided to dedicate a fifth (3000 sq km) of the country's 15,000-sq-km forest estate to management as Strict Nature Reserves (SNRs)for the protection of biodiversity. The Forest Department subsequently undertook a 5-year programme of biological inventory and socioeconomic evaluation to select appropriate areas for designation. Sixty-five of the country's principal forests (including five now designated as National Parks) were systematically evaluated for biodiversity, focusing on five ‘indicator’ taxa (woody plants, birds, small mammals, butterflies and large moths). A scoring system was developed to compare and rank sites according to their suitability for nature reserve establishment and 11 key sites were identified, which, when combined with the country's 10 national parks, account for more than 95 per cent of Uganda's species. In order to satisfy multiple-use management objectives, the Man and the Biosphere model of reserve design is being applied at each forest, by designating a centrally located core area as SNR, with increasingly intensive resource use permitted towards the periphery of each reserve and adjacent rural communities.

Abstract:

The Rushworth Forest is a Box and Ironbark open sclerophyll forest in central Victoria that has been subject to a long history of gold mining activity and forest utilisation. This paper documents the major periods of land use history in the Rushworth Forest and comments on the environmental changes that have occurred as a result. During the 1850s to 1890s, the Forest was subject to extensive gold mining operations, timber resource use, and other forest product utilisation, which generated major changes to the forest soils, vegetation structure and species cover. From the 1890s to 1930s, concern for diminishing forest cover across central Victoria led to the creation of timber reserves, including the Rushworth State Forest. After the formation of a government forestry department in 1919, silvicultural practices were introduced which aimed at maximising the output of tall timber production above all else. During World War II, the management of the Forest was taken over by the Australian Army as Prisoner of War camps were established to harvest timber from the Forest for firewood production. Following the War, the focus of forestry in Victoria moved away from the Box and Ironbark forests, but low value resource utilisation continued in the Rushworth Forest from the 1940s to 1990s. In 2002, about one-third of the Forest was declared a National Park and the other two-thirds continued as a State Forest. Today, the characteristics of the biophysical environment reflect the multiple layers of past land uses that have occurred in the Rushworth Forest.

Abstract:

AbstractThe rusty-spotted cat Prionailurus rubiginosus is the smallest wildcat in the world, endemic to India, Nepal and Sri Lanka. Although new occurrence records have recently been reported from different geographic localities in India and Nepal, there is still a lack of information on its biology and habitat use that are required for its conservation planning. Herein, we report results from systematic, long-term (2014–2018) camera trapping in Kanha Tiger Reserve, India, to evaluate the habitat use, suitability and activity pattern of the rusty-spotted cat and model its local distribution with habitat and anthropogenic covariates. Thick canopied forest and rugged terrain were found to be extensively used and preferred by the rusty-spotted cat. It was also recorded in the multiple-use buffer zone forests in close proximity to agriculture. The species is nocturnal and its activity seems to coincide with its major prey. The guiding philosophy of tiger reserves in India is to use the tiger as an umbrella species for biodiversity conservation, and often these reserves are intensively managed to enhance tiger and prey populations. This approach, however, may not cater to the requirements of other less charismatic sympatric species, and those of the rusty-spotted cat also need to be considered for its continued survival.

Abstract:

The concept of biological diversity (biodiversity) is reviewed, with special attention to its measurement and natural trends. While generalizations regarding the necessity of biodiversity need to be interpreted with caution, it is argued that biodiversity should be protected in more ecosystem and landscape reserves, and that biodiversity is a reasonable management objective on timber lands as well. Maintaining biodiversity is important because we cannot always identify which individual species are critical to ecosystem sustainability, nor which species may be useful to mankind in future. Many wild species can provide useful natural products and genetic material, and can serve as ecological indicators. Diversity reduces pest and disease problems, and encourages recovery from disturbance. Uncertainty exists with regard to climate change and future socioeconomic values. It is therefore prudent to maximize flexibility by promoting a wide array of species and potential products. Suggestions are offered on how to promote biodiversity in multiple-use forests. Key words: biological diversity, climate change, environmental ethics, forest inventory, genetic conservation, integrated resource management, indicator species, landscape ecology, multiple-use, natural products, stability, uncertainty.

Abstract:

The recent development of new processing facilities in Meadow Lake, Saskatchewan has created a long-term market for timber in the region. Although these processing facilities are currently supplied by crown timber reserves, increasing pressure on public forest resources from multiple users has caused processors to consider private woodlots as a supplemental source of fibre. A survey was undertaken to investigate conditions under which landowners may respond to the emerging demand by managing their timber resources for harvest and sale.Survey results indicate that, although virtually no management or harvesting has occurred in the past, approximately half of those interviewed would consider timber management and harvesting in the future. Logit analysis identified landowner characteristics that were related to landowners' willingness to consider forest management and harvest in the future and the likelihood that they would consider a timber contract. Significant characteristics of landowners in influencing the propensity to manage and harvest their woodlots included: the diversity of farm operations, the length of family tenure of the land, the number of ways respondents use their forest land, and area of forest owned. A preferred timber contract was identified as having: a duration of 1 to 5 years, young growth established at the end of the contract term, and payments for harvesting and management services made through a crop share arrangement. Key words: private forestry, forest economics, timber contracts, landowner characteristics, woodlot management

Abstract:

Climate change is threatening our ability to manage forest ecosystems sustainably. Despite strong consensus on the need for a broad portfolio of options to face this challenge, diversified management options have yet to be widely implemented. Inspired by functional zoning, a concept aimed at optimizing biodiversity conservation and wood production in multiple-use forest landscapes, we present a portfolio of management options that intersects management objectives with forest vulnerability to better address the wide range of goals inherent to forest management under climate change. Using this approach, we illustrate how different adaptation options could be implemented when faced with impacts related to climate change and its uncertainty. These options range from establishing ecological reserves in climatic refuges, where self-organizing ecological processes can result in resilient forests, to intensive plantation silviculture that could ensure a stable wood supply in an uncertain future. While adaptation measures in forests that are less vulnerable correspond to the traditional functional zoning management objectives, forests with higher vulnerability might be candidates for transformative measures as they may be more susceptible to abrupt changes in structure and composition. To illustrate how this portfolio of management options could be applied, we present a theoretical case study for the eastern boreal forest of Canada. Even if these options are supported by solid evidence, their implementation across the landscape may present some challenges and will require good communication among stakeholders and with the public.

Abstract:

This is a historical study of the intersection of political economy with natural resources management, as played out on the national forests between 1945-1991. Specifically, it focuses on two core national forest management policies; sustained yield and multiple use. These two policy directives represent an attempt by the public and elected officials to apply principles of sustainable development to publicly-owned forest lands, and to ensure that a wide variety of both market and nonmarket forest values are preserved for the benefit of present and future generations. Interest groups, the Forest Service, and policy makers have conceived of sustained yield and multiple use in different and evolving ways over the years. This study explores how these principles have been variously defined and either implemented or thwarted. After World War Two, with escalating demands on national forest resources, the U.S. Forest Service turned to "intensive management" as a technological method of enhancing natural forest productivity and mitigating the environmental effects of increased use. But the agency's optimistic vision of efficient, sustained production of forest commodities through technical mastery over nature has met overwhelming fiscal, environmental, technical, and political obstacles. Nevertheless, agency leaders, industry advocates, and politicians have consistently promulgated an optimistic faith that intensive applications of labor, capital, and technology can maximize and harmonize multiple uses, rehabilitate damaged resources, and sustain high levels of outputs in perpetuity--despite repeated failures to achieve balanced multiple use management and to manage grazing and timber extraction at sustainable levels. The conspiracy of optimism ideologically justifies continued unsustainably high levels of resource extraction. Changing public values since the 1960s and the popularization of ecology have initiated a growing skepticism toward the premises of intensive management. At the same time, field level forest managers have grown frustrated with top-down imposition of resource production quotas and the lack of adequate political, fiscal, and organizational support for sound forest management. As the last old growth forests fall to the chainsaw, and as the federal subsidies required to access these remote timber stands on the national forests escalate, public controversy deepens. In this decade of the national forest centennial a revolt of conscience has erupted among grassroots Forest Service personnel, and a strong challenge from the environmental community has gained momentum. Another major period of policy evaluation and revision appears to be taking place. Whether the conspiracy of optimism can continue to sustain the old status quo is questionable.
