    First the forest: conservation, 'community' and 'participation' in South West Cameroon

    Get PDF
    Western concern with ‘conserving’ or ‘managing’ the rain forests of Africa has led to the setting up of a number of conservation projects. In such projects the ‘participation’ of the ‘community’ in forest conservation has become the new orthodoxy. However, proposals about local people's participation presume that defining the future of the forest is a straight contest between the alternatives of conservation or forest clearing. Such proposals also presume that the existence of communities is non-problematic. In contrast, this article documents that there is already considerable local debate about forest use and conservation, much of it among those excluded from the formal arena of politics and policy-making. Concern with ‘the environment’ includes concern about the perpetuation of society, and represents a clear continuation of West African village cosmologies focused on the societalisation of space. At the same time, conservation aims of ‘keeping the forest as it is’ have few resonances, since forest people see society itself as an artful, but often problematic, construction in which the conversion of the forest plays a central part. In conclusion, the article suggests that the key to environmental management must be for external agencies to articulate with the interests and values of those who hold a legitimate stake in African forest resources

    In-situ Conservation of wild forest coffee-Exploring the potential of participatory forest management in south west Ethiopia

    Maintaining the gene pool of Coffea arabica in the forests of South West Ethiopia, where this plant evolved and has its genetic hearth, is a challenge of global importance. Participatory Forest Management (PFM) and Biosphere Reserves (BR) are among the various initiatives being tested to maintain this forest and its biodiversity that includes major stands of wild Arabica coffee. This paper makes a comparative analysis of PFM and BR approaches to conservation as applied in Ethiopia. While BR legislation provides a framework for enforcement, there can be difficulties in achieving this on the ground especially with the pressures from communities on these forests and the limited resources of the state to enforce protection. In some cases because core zones are alienated from communities these areas are seen as open access by local communities and have suffered especially from fires and focused deforestation. An alternative approach for in situ conservation of wild coffee using PFM has been explored in South West forest of Ethiopia. PFM, by engaging local communities in the management of forests is believed to increase economic and environmental benefits while reducing costs of conservation..Monthly field monitoring by communities and annual reviews with the government have turned this forest from open access to community controlled. Critically the development of market links and value chains for forest products is motivating communities to maintain and improve their forest. It is hoped that PFM will create a win-win goal – enhancing the role played by the forest in rural development and ensuring the conservation of wild coffee genetic resources

    The Invisible Forest: Conservation Easement Databases and the End of the Clandestine Conservation of Natural Lands

    Get PDF
    Olmsted talks about invisible forest refers to forest lands -- and, for that matter, any other land types -- protected by a perpetual conservation easement, the existence and location of which are concealed from the public, whether deliberately or because of the opaque nature of the easement process. Because easements, like other forms of deeds, must be recorded at the local land registry or recorder\u27s office, they can never be made undiscoverable. But, despite the efforts of some states and conservation organizations to compile conservation easement data for public consumption, there are few functional systems that comprehensively track and provide easy access to conservation easement data

    Wetland biodiversity in coastal New South Wales: the Wallis Lake catchment as a case study

    Get PDF
    The floristic composition and environmental relations of wetland vegetation in the Wallis Lake catchment (32˚ 09’S; 152˚ 20’E), area 1292 km2, on the lower North Coast of NSW are described. The catchment supports wetlands listed as Endangered Ecological Communities (NSW Threatened Species Conservation Act 1995) and plant species of high conservation value. A methodology of air photo interpretation, site-based sampling (114 quadrats) and landscape differentiation was developed. A total of 393 vascular plant taxa were recorded (including 10% exotics). Wetland vegetation formations and subformations including mangrove forest, swamp sclerophyll forest, wet heathland, chenopod shrubland, tussock grassland, sedgeland and rushland are described using numerical classification. 31 plant species of national or regional conservation significance are identified. Four Endangered Ecological Communities are discussed – Coastal Saltmarsh, Swamp Oak Floodplain Forest, Swamp Sclerophyll Forest on Coastal Floodplains, and Freshwater Wetlands on Coastal Floodplains. A key recommendation is the completion of reliable wetland vegetation and soil landscape mapping for all land tenures in the catchment – to assess wetland condition and conservation significance, and representation in formal conservation reserves, thereby directing future priorities for the protection of wetland biodiversity on both public and private lands. The methodology developed can be applied to the survey and conservation of wetland biodiversity in other parts of coastal NSW

    Scientifically based biodiversity management in timber concessions: contribution to conservation and sustainable use of biodiversity

    Full text link
    During the past 25 years, forest laws in Central African countries have undergone major changes. Management plans were made mandatory: nearly 19 million hectares of timber concessions (38% of total granted concessions) were subject to a management plan in 2013 and the dynamics is currently underway. The management plan is based on a set of technical and scientific studies, including statistical surveys (management inventories) covering the whole concession and taking into account all timber species, large mammals and the main non timber forest products. These inventories allow, at concession level, to characterize ecosystems and to assess the forest conservation values, through floristic and faunal biodiversity indicators and by taking into account threats to the forest ecosystems, especially anthropogenic ones. Such management inventories are used especially for planning and forecasting harvests, while minimising environmental impacts on the forest structure and functioning, and retaining regeneration capacities of the timber species and the forest ecosystems. The knowledge gained on specific and ecosystemic biodiversity helps to define management rules to ensure the sustainability of different timber species' populations, noticeably the exploited ones. It is also used to design areas within the concessions were exploitation will not take place due to conservation interest (most biodiversity-rich areas, protection of rare or endangered species...). Such so-called “conservation series” therefore complement the protected areas network. Well-managed forest concessions can help conserve the regional forest ecosystems and maintain essential functions that they provide. However, management plans were up to now designed at the concession scale. Data acquired in forest concessions also significantly contribute to improve knowledge of the forest ecosystems and their functioning at the regional level. Using this data, the CoForChange Project (http://www.coforchange.eu) issued a map of the forest ecosystems developed in the "Sangha River Interval" region. This project suggested that those forest ecosystems could react differently to disturbance, and could need an adaptation of management methods to each ecosystem. Based on forest inventories, other initiatives are underway to map the forest types and the biomass stock at the scale of Central Africa, and might be of particular interest for policy decisions on forest ecosystems.

    Insights on the role of forest cover and on the changes in forest cover on thirty-five endangered mammal species distributions

    The changes in forest cover can determine the survival of terrestrial endangered mammal species in the wild. This study assessed the impacts of forest cover changes on endangered mammal species distribution at global scale aiming to understand how the changes in forest cover may have impacted the distributions of 35 endangered small and large-body terrestrial mammals. There were used forest data obtained from time-series analyses of Landsat images between 2000 and 2014, species occurrence records collected by observations between 2000 and 2015 of Global Biodiversity Information Facility and species range data of International Union for Nature Conservation (IUCN) of the year 2015, to test the ‘natural and resource conditions’ hypothesis. Hypothesis on ‘natural and resource conditions’ produced models with high prediction accuracy of above 70 percent for 88 percent of 35 species models. The changes in forest cover explained species occurrences in 10 percent of all species models. In average, 59 percent of species occurrence records overlapped with species range data. The 51 percent of all species had no occurrence records between 2000 and 2015. Species and forest data collection as well as transnational cooperation for conservation of species roaming in the wild in upland forested areas and in cross-border areas may be critical for endangered mammal species conservation

    Synergies of planning for forests and planning for Natura 2000: Evidences and prospects from northern Italy

    Improvements in the management of Natura 2000 sites are essential to achieve the targets set out by the Habitats and Birds Directives of the European Union. A current focus is on the development of management plans, which are fundamental instruments in the implementation of conservation measures. This study explores the viability of using existing forest plans to assist in this purpose. As case study, we consider the regulatory framework of the Veneto Region, northern Italy. We collected quantitative and qualitative data on forest plans at the regional and at three sub-regional spatial scales: local, district, and biogeographical. Forest plans cover about 54% of the terrestrial area of Natura 2000 sites in Veneto, and 75% of Sites of Community Importance in the Alpine biogeographical region. At the local scale of analysis, metrics from forest plans represent a valuable historical record which can be used to interpret the current state and future trends, especially for forests with long management records. These data can be used to assess biodiversity indicators for the monitoring of Natura 2000 forest and non-forest habitats, in compliance with Article 17 of the Habitats Directive. Moreover, the heterogeneous stand conditions which are promoted by some forest management approaches can improve the conservation efforts for some habitats and species. The scale of local forest plans are typically the most appropriate for implementing habitat management strategies. From this study, we conclude that management authorities should take advantage of the wide spatial coverage and distribution of existing forest plans, especially in mountain areas inside and outside the Natura 2000 network, for the successful conservation of European Union habitats and species

    Monitoring, reporting and vrification for national REDD+programmes: two proposals

    Get PDF
    Different options have been suggested by Parties to the UNFCCC (United Framework Convention on Climate Change) for inclusion in national approaches to REDD and REDD + (reduced deforestation, reduced degradation, enhancement of forest carbon stocks, sustainable management of forest, and conservation of forest carbon stocks). This paper proposes that from the practical and technical points of view of designing action for REDD and REDD + at local and sub-national level, as well as from the point of view of the necessary MRV (monitoring, reporting and verification), these should be grouped into three categories: conservation, which is rewarded on the basis of no changes in forest stock, reduced deforestation, in which lowered rates of forest area loss are rewarded, and positive impacts on carbon stock changes in forests remaining forest, which includes reduced degradation, sustainable management of forest of various kinds, and forest enhancement. Thus we have moved degradation, which conventionally is grouped with deforestation, into the forest management group reported as areas remaining forest land, with which it has, in reality, and particularly as regards MRV, much more in common. Secondly, in the context of the fact that REDD/REDD + is to take the form of a national or near-national approach, we argue that while systematic national monitoring is important, it may not be necessary for REDD/REDD + activities, or for national MRV, to be started at equal levels of intensity all over the country. Rather, areas where interventions seem easiest to start may be targeted, and here data measurements may be more rigorous (Tier 3), for example based on stakeholder self-monitoring with independent verification, while in other, untreated areas, a lower level of monitoring may be pursued, at least in the first instance. Treated areas may be targeted for any of the three groups of activities (conservation, reduced deforestation, and positive impact on carbon stock increases in forest remaining forest)

    Remnants of the Waikato: native forest survival in a production landscape

    This paper addresses the issue of conservation of native biodiversity on privately owned farmland in New Zealand. Based on surveys of Waikato dairy farmers as exemplars of intensive agricultural practice, it examines factors that influence the survival of native forest on land with potential for commercial production. Results suggest that a significant proportion of Waikato dairy farmers regard native forest favourably although the proportion of farmers who actively conserve their native forest is small. Factors that assist the persistence of native forest on dairy farms include personal characteristics of the farmer, past accidents of history which have left forest remnants in place, and physical characteristics of the farm such as topography. While the conservation of native biodiversity within this intensively farmed landscape is strongly influenced by political economy pressures that encourage production, non-utilitarian motives such as aesthetic enjoyment and family heritage can serve to counter the production ethic

    What Has to Change for Forests to be Saved? A Historical Example From the United States

    Get PDF
    This article looks at the conservation of American forests in the nineteenth and twentieth centuries to cast light on the prospects for global forest conservation in the twenty-first. At the beginning of the nineteenth century, Americans understood their forests as good only for cutting. By the end of the century a national scheme existed for comprehensive and permanent forest conservation. This new scheme became possible thanks to changes in scientific knowledge, the ideological self-image of the country, political institutions, and the imagination and moral commitments of citizens and social movements. A look at the changes that laid the foundations of national forest conservation might help to show what would have to happen for international forest conservation to emerge. Alternatively, it might highlight differences between those past developments and present circumstances, showing how past is not prologue. In this case, the upshot is some of both
