Integrating Multiple Spatial Datasets to Assess Protected Areas: Lessons Learnt from the Digital Observatory for Protected Areas (DOPA)

The Digital Observatory for Protected Areas (DOPA) has been developed to support the European Union’s efforts in strengthening our capacity to mobilize and use biodiversity data so that they are readily accessible to policymakers, managers, researchers and other users. Assessing protected areas for biodiversity conservation at national, regional and international scales implies that methods and tools are in place to evaluate characteristics such as the protected areas’ connectivity, their species assemblages (including the presence of threatened species), the uniqueness of their ecosystems, and the threats these areas are exposed to. Typical requirements for such analyses are data on protected areas, information on species distributions and threat status, and information on ecosystem distributions. By integrating all these global data consistently in metrics and indicators, the DOPA provides the means to allow end-users to evaluate protected areas individually but also to compare protected areas at the country and ecoregion level to, for example, identify potential priorities for further conservation research, action and funding. Since the metrics and indicators are available through web services, the DOPA further allows end-users to develop their own applications without requiring management of large databases and processing capacities. In addition to examples illustrating how the DOPA can be used as an aid to decision making, we discuss the lessons learnt in the development of this global biodiversity information system, and outline planned future developments for further supporting conservation strategies.

Understanding local‐scale drivers of biodiversity outcomes in terrestrial protected areas

Conservation relies heavily on protected areas (PAs) maintaining their key biodiversity features to meet global biodiversity conservation goals. However, PAs have had variable success, with many failing to fully maintain their biodiversity features. The current literature concerning what drives variability in PA performance is rapidly expanding but unclear, sometimes contradictory, and spread across multiple disciplines. A clear understanding of the drivers of successful biodiversity conservation in PAs is necessary to make them fully effective. Here, we conduct a comprehensive assessment of the current state of knowledge concerning the drivers of biological outcomes within PAs, focusing on those that can be addressed at local scales. We evaluate evidence in support of potential drivers to identify those that enable more successful outcomes and those that impede success and provide a synthetic review. Interactions are discussed where they are known, and we highlight gaps in understanding. We find that elements of PA design, management, and local and national governance challenges, species and system ecology, and sociopolitical context can all influence outcomes. Adjusting PA management to focus on actions and policies that influence the key drivers identified here could improve global biodiversity outcomes.

Plant diversity and associated traditional ecological knowledge of Soliga tribal community of Biligiriranga Swamy Temple Tiger Reserve (BRTTR):A biogeographic bridge for Western and Eastern Ghats, India

The Biligiriranga Swamy Temple Tiger Reserve (BRTTR) is a chain of hills and important ecosystems, which forms the biogeographic ridge between two biodiversity rich areas namely the Western Ghats and the Eastern Ghats of India. The hills are being resided by the Soliga tribal community for the centuries and accorded with a status of Tiger reserve in December 2010 under Project Tiger administered by National Tiger Conservation Authority. The study was done on the traditional ecological knowledge of the people in healthcare system. A total of 108 plants belonging to 51 families have been identified, which the Soliga tribal community uses for curing various ailments. The local name, part used, disease cured and prescribed dosage are properly documented while developing detailed inventory on the plant biodiversity of the region. The ecological status of the plant species is also reported to understand their conservation status at global level. The ailments listed are categorized in major and minor ailments. The results indicate that 76% people still depend on traditional health care systems to cure minor ailments. However, 04% people depend on the traditional health care system to cure major diseases. And 33% people were found to be followed traditional and allopathic treatment for curing the major ailments like arthritis, asthma, diabetes, kidney stones, tuberculosis etc. Among the recorded species 09 are found under vulnerable category, followed by endangered (07), endemic (03), low risk-least concerned (02) and data deficient (01). Keeping change in policy scenario in view there would be possibility to relocate tribal community from some of the areas in core of BRTTR to other places. This shift coupled with various other factors for example restrictions on the collection of forest resources, change in socioeconomic setup, and acculturation which is taking place in the society, the ecological and indigenous knowledge of the region would face danger of vanishing. This study support India's initiatives of protecting TEK from patent issues where non-codified information was codified for the future use. And argues that the biodiversity conservation in protected areas requires regular monitoring of various species within the purview of human interactions on ecosystems for various needs.

Cross-cultural values and management preferences in protected areas of Norway and Poland

Protected areas provide important ecosystem services globally but few studies have examined how cultural differences influence the distribution of cultural ecosystem values and management preferences. We used internet-based public participation GIS (PPGIS) in the countries of Norway and Poland to identify ecosystem values and management preferences in protected areas held by regional residents and site users. We found significant differences in the type and quantity of ecosystem values with Norwegians mapping more values relating to use of resources (e.g., hunting/fishing, gathering) and Polish respondents mapping more environmental values such as scenery, biological diversity, and water quality. With respect to management preferences, Norwegians identified more preferences for resource utilization while Polish respondents identified more preferences for conservation. Norwegian respondents were more satisfied with protected area management and local participation which can be explained by historical, legal, and cultural differences between the two countries. For Norway, biodiversity conservation in protected areas will continue to be guided by sustainable use of protected areas, rather than strict nature protection, with management favoring local board control and active public participation. For Poland, change in protected area management to enhance biodiversity conservation is less certain, driven by national environmental values that conflict with local values and preferences, continuing distrust in government, and low levels of civic participation. Differential efficacy in PPGIS methods – Norway with greater participation from household sampling and Poland with greater response using social media – suggest different strategies will be required for effective public engagement in protected area planning and management.

Predicting the future effectiveness of protected areas for bird conservation in Mediterranean ecosystems under climate change and novel fire regime scenarios

AbstractAimGlobal environmental changes challenge traditional conservation approaches based on the selection of static protected areas due to their limited ability to deal with the dynamic nature of driving forces relevant to biodiversity. The Natura 2000 network (N2000) constitutes a major milestone in biodiversity conservation in Europe, but the degree to which this static network will be able to reach its long‐term conservation objectives raises concern. We assessed the changes in the effectiveness of N2000 in a Mediterranean ecosystem between 2000 and 2050 under different combinations of climate and land cover change scenarios.LocationCatalonia, Spain.MethodsPotential distribution changes of several terrestrial bird species of conservation interest included in the European Union's Birds Directive were predicted within an ensemble‐forecasting framework that hierarchically integrated climate change and land cover change scenarios. Land cover changes were simulated using a spatially explicit fire‐succession model that integrates fire management strategies and vegetation encroachment after the abandonment of cultivated areas as the main drivers of landscape dynamics in Mediterranean ecosystems.ResultsOur results suggest that the amount of suitable habitats for the target species will strongly decrease both inside and outside N2000. However, the effectiveness of N2000 is expected to increase in the next decades because the amount of suitable habitats is predicted to decrease less inside than outside this network.Main conclusionsSuch predictions shed light on the key role that the current N2000 may play in the near future and emphasize the need for an integrative conservation perspective wherein agricultural, forest and fire management policies should be considered to effectively preserve key habitats for threatened birds in fire‐prone, highly dynamic Mediterranean ecosystems. Results also show the importance of considering landscape dynamics and the synergies between different driving forces when assessing the long‐term effectiveness of protected areas for biodiversity conservation.

Assessing impact of forest cover change dynamics on high nature value farmland in Mediterranean mountain landscape

A general trend of scrub encroachment and natural forest expansion (old-field succession) has been occurring in the past fifty years in Mediterranean mountain areas. While this phenomenon enhances a series of ecological processes and environmental services, it may represent a threat for biodiversity conservation when occurring on high nature value (HNV) extensive farmland. These open areas, created by traditional farming systems, have been recognized as a critically important European biodiversity resource. Understanding the drivers of Land Use and Land Cover Change (LUCC) and their implications on the dynamics of forest and HNV farmland habitats plays a crucial role in biodiversity conservation in protected areas. In this perspective, the case study here presented aims to model recent (1989-2008) LUCC in a National Park of the Central Apennines (Italy) and to produce a mid-term forecast (2008-2020). In the past twenty years, 57% of the land uptake by shrubland and 46% by forest has been occurring on former HNV farmland. Mid-term projections (2008-2020) confirm further HNV farmland decline. Localization of HNV farmland habitats vulnerable to change is a valuable decision-making tool to tradeoff in protected areas the conservation of traditional landscapes with the increase of forest and shrubland areas. In this perspective, concrete socio-economical and silvicultural measures are outlined to preserve these socially and economically-fragile open habitats.

Towards sustainable financing of protected areas: A brief overview of pertinent issues

According to the International Union for the Conservation of Nature (IUCN) now known as the World Conservation Union (IUCN), a protected area refers to a clearly defined geographical space, recognised, dedicated and managed through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values. The recognition of the role of protected areas in biodiversity conservation is manifested in several regional and international policies and legislation underscoring the need for financing of protected areas. These policies and legislation include the Convention on Biodiversity, Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), World Heritage Convention and the Ramsar Convention on Wetlands. Most countries have ratified these conventions and consequently formulated national policies and legislation supporting biodiversity conservation and most are at implementation stage. However, protected areas are still not adequately funded regardless of their unique contribution to nature conservation. Challenges and opportunities in protected areas financing have been identified, conceptual frameworks for sustainable protected areas financing have been formulated and the various components that make a successful protected area are known. Key words: Protected area, sustainable financing, tourism, international conventions, values, biodiversity, conservation, heritage.

Climate change is predicted to negatively influence Moroccan endemic reptile richness. Implications for conservation in protected areas

The identification of species-rich areas and their prognosticated turnover under climate change are crucial for the conservation of endemic taxa. This study aims to identify areas of reptile endemicity richness in a global biodiversity hot spot (Morocco) under current and future climatic conditions and to investigate the role of protected areas in biodiversity conservation under climate change. Species distribution models (SDM) were performed over the distribution of 21 endemic reptiles, combined to estimate current species richness at 1 × 1 km resolution and projected to years 2050 and 2080 according to distinct story lines and ensemble global circulation models, assuming unlimited and null dispersion ability. Generalized additive models were performed between species richness and geographic characteristics of 43 protected areas. SDM found precipitation as the most important factor related to current species distributions. Important reductions in future suitable areas were predicted for 50 % of species, and four species were identified as highly vulnerable to extinction. Drastic reductions in species-rich areas were predicted for the future, with considerable variability between years and dispersal scenarios. High turnover rates of species composition were predicted for eastern Morocco, whereas low values were forecasted for the Northern Atlantic coast and mountains. Species richness for current and future conditions was significantly related to the altitude and latitude of protected areas. Protected areas located in mountains and/or in the Northern Atlantic coast were identified as refugia, where population monitoring and conservation management is needed.

Towards sustainable financing of protected areas: A case study of the Swaziland National Trust Commission (SNTC)

Conservation of biological diversity is one of the main elements of sustainable development, given that biodiversity is the basis of life on earth. The current and potential role of protected areas in biodiversity conservation cannot be overemphasized. The objective of the study was to provide protected area managers with new innovations in protecting area financing on how to improve and diversify funding sources, basically towards sustainable financing. This was a case study, using a qualitative research design where a purposive sample of various levels of management of the Swaziland National Trust Commission’s protected areas was selected for interviews. It can be concluded that the Swaziland National Trust Commission (SNTC) has great potential for the conservation of natural and cultural heritage in Swaziland, as well as venturing into tourism. However, the SNTC is faced with financing challenges and needs interim models to ensure sustainable financing through the transition phase (restructuring and commercialisation) which might take a long time. Seven recommendations were made. These are: development of a sustainable tourism framework; adopting a business approach; embarking on a joint natural product enterprise development; designing a set of criteria for a viable marketing strategy; considering project finance as an option; developing investment proposals; and a theoretical framework for long-term financing of SNTC’s protected areas. Key words: Protected area, sustainable financing, tourism, international conventions, values, biodiversity, conservation, heritage.

Current models broadly neglect specific needs of biodiversity conservation in protected areas under climate change.

BackgroundProtected areas are the most common and important instrument for the conservation of biological diversity and are called for under the United Nations' Convention on Biological Diversity. Growing human population densities, intensified land-use, invasive species and increasing habitat fragmentation threaten ecosystems worldwide and protected areas are often the only refuge for endangered species. Climate change is posing an additional threat that may also impact ecosystems currently under protection. Therefore, it is of crucial importance to include the potential impact of climate change when designing future nature conservation strategies and implementing protected area management. This approach would go beyond reactive crisis management and, by necessity, would include anticipatory risk assessments. One avenue for doing so is being provided by simulation models that take advantage of the increase in computing capacity and performance that has occurred over the last two decades.Here we review the literature to determine the state-of-the-art in modeling terrestrial protected areas under climate change, with the aim of evaluating and detecting trends and gaps in the current approaches being employed, as well as to provide a useful overview and guidelines for future research.ResultsMost studies apply statistical, bioclimatic envelope models and focus primarily on plant species as compared to other taxa. Very few studies utilize a mechanistic, process-based approach and none examine biotic interactions like predation and competition. Important factors like land-use, habitat fragmentation, invasion and dispersal are rarely incorporated, restricting the informative value of the resulting predictions considerably.ConclusionThe general impression that emerges is that biodiversity conservation in protected areas could benefit from the application of modern modeling approaches to a greater extent than is currently reflected in the scientific literature. It is particularly true that existing models have been underutilized in testing different management options under climate change. Based on these findings we suggest a strategic framework for more effectively incorporating the impact of climate change in models exploring the effectiveness of protected areas.

A Spectacular Eco‐Tour around the Historic Bloc: Theorising the Convergence of Biodiversity Conservation and Capitalist Expansion

Abstract: The simultaneous proliferation of protected areas for biodiversity conservation and neoliberal market expansion has sparked a growing body of work, which suggests that these are mutually reinforcing processes that reflect alliances between conservationist and capitalist agendas. Because this alliance is so counter intuitive to the ways in which biodiversity conservation is popularly understood, theoretical perspectives concerning these relationships have been slow in emerging. Drawing from Gramsci's ideas of hegemony and historic bloc, we propose a theoretical framework systematically to inform understandings and investigations of these transformations. We suggest that they are driven by the convergence of networks of interests, which work to resolve the apparent contradictions between demands for continued economic growth and growing concerns about what it portends for the future of our planet. These in turn rely on spectacular presentations of conservation interventions, conservation success stories, and their putative linkages to ecosystems and the global economy.

Potencial invasor de duas cultivares de Melinis minutiflora no cerrado brasileiro - características de sementes e estabelecimento de plântulas

A invasão biológica por espécies exóticas é considerada uma das principais ameaças para a conservação da biodiversidade em áreas protegidas. Devido à sua agressividade, Melinis minutiflora P. Beauv. (capim-gordura) é a gramínea que tem causado o maior impacto sobre a flora nativa no Cerrado brasileiro. Este estudo objetivou avaliar características de sementes e de estabelecimento de plântulas que podem afetar o potencial invasor de duas cultivares do Melinis minutiflora em uma área de Cerrado sensu stricto dentro de uma Unidade de Conservação. As avaliações de campo e laboratório mostram que a produção de sementes foi de 192 kg/ha (71.946 sementes viáveis/m²) e 171 kg/ha (81.690 sementes viáveis/m²) pelas cultivares Cabelo-de-Negro e Roxo, respectivamente, e as sementes recém-colhidas apresentaram alta viabilidade e alta dormência. No tocante à dinâmica de colonização, o enterrio de sementes reduz a emergência de plântulas, mas não impede a emergência de plântulas até a profundidade de 3 cm, entretanto a partir da profundidade de 4 cm as plântulas não conseguem emergir. A emergência de plântulas ocorre entre dezembro e março. Fatores adversos como sombreamento, competição intra e interespecífica, baixa fertilidade do solo e estresse hídrico não eliminam totalmente os indivíduos que se estabeleceram no período chuvoso. As cultivares de Melinis minutiflora mostraram comportamento reprodutivo bastante similar, e os fatores estudados ajudaram a explicar parcialmente o sucesso apresentado por essa gramínea em colonizar ambientes naturais no Cerrado brasileiro.

The Links between Protected Areas, Faiths, and Sacred Natural Sites

Most people follow and are influenced by some kind of spiritual faith. We examined two ways in which religious faiths can in turn influence biodiversity conservation in protected areas. First, biodiversity conservation is influenced through the direct and often effective protection afforded to wild species in sacred natural sites and in seminatural habitats around religious buildings. Sacred natural sites are almost certainly the world's oldest form of habitat protection. Although some sacred natural sites exist inside official protected areas, many thousands more form a largely unrecognized "shadow" conservation network in many countries throughout the world, which can be more stringently protected than state-run reserves. Second, faiths have a profound impact on attitudes to protection of the natural world through their philosophy, teachings, investment choices, approaches to land they control, and religious-based management systems. We considered the interactions between faiths and protected areas with respect to all 11 mainstream faiths and to a number of local belief systems. The close links between faiths and habitat protection offer major conservation opportunities, but also pose challenges. Bringing a sacred natural site into a national protected-area system can increase protection for the site, but may compromise some of its spiritual values or even its conservation values. Most protected-area managers are not trained to manage natural sites for religious purposes, but many sacred natural sites are under threat from cultural changes and habitat degradation. Decisions about whether or not to make a sacred natural site an "official" protected area therefore need to be made on a case-by-case basis. Such sites can play an important role in conservation inside and outside official protected areas. More information about the conservation value of sacred lands is needed as is more informed experience in integrating these into wider conservation strategies. In addition, many protected-area staff need training in how to manage sensitive issues relating to faiths where important faith sites occur in protected areas.

Efficiency and effectiveness in representative reserve design in Canada: The contribution of existing protected areas

To be effective, reserve networks should represent all target species in protected areas that are large enough to ensure species persistence. Given limited resources to set aside protected areas for biodiversity conservation, and competing land uses, a prime consideration for the design of reserve networks is efficiency (the maximum biodiversity represented in a minimum number of sites). However, to be effective, networks may sacrifice efficiency. We used reserve selection algorithms to determine whether collections of existing individual protected areas in Canada were efficient and/or effective in terms of representing the diversity of disturbance-sensitive mammals in Canada in comparison to (1) an optimal network of reserves, and (2) sites selected at random. Unlike previous studies, we restricted our analysis to individual protected areas that met a criterion for minimum reserve size, to address issues of representation and persistence simultaneously. We also tested for effectiveness and efficiency using historical and present-day data to see whether protected area efficiency and/or effectiveness varied over time. In general, existing protected areas did not effectively capture the full suite of mammalian species diversity, nor are most existing protected areas part of a near-optimal solution set. To be effective, Canada’s network of reserves will require at minimum 22 additional areas of >2700 km 2. This study shows that even when only those reserves large enough to be effective are considered, protected areas systems may not be representative, nor were they representative at the time of establishment.

Quantifying species richness at multiple spatial scales in a Natura 2000 network

Even if the establishment of nature reserves is to date a reality and the increase of protected areas is going to grow year after year, monitoring programs aiming to assess the effectiveness of the established protected areas for biodiversity conservation are still needed. That is the case for the Natura 2000 network in Europe, for which monitoring methods and programs are not yet well-established. A probabilistic sampling procedure is proposed and tested for quantifying and monitoring plant species diversity within a local network of protected areas, namely the Natura 2000 network in the Siena Province, Italy. On the basis of a sampling strategy of one 100 m 2 plot randomly located in each 1 km × 1 km cell, four Sites of Community Importance (SCIs) were investigated in 2005. The gradients in species composition at the plot scale were largely related to elevation and forest cover. The species richness values of the four SCIs were compared by means of sample-based rarefaction curves. Then, additive partiti...

The Importance of Law Enforcement for Protected Areas: Don't Step Back! Be Honest – Protect!

The role of protected areas in biodiversity conservation is widely accepted. Controversy, however, exists over the best way to ensure the long-term persistence of functional protected areas themselves. Strict protection is the most promising way, even if this means that benefits of individual human beings have to be compromised at times.

Ecological Networks as Conceptual Frameworks or Operational Tools in Conservation

The establishment of ecological networks (ENs) has been proposed as an ideal way to counteract the increasing fragmentation of natural ecosystems and as a necessary complement to the establishment of protected areas for biodiversity conservation. This conservation tool, which comprises core areas, corridors, and buffer areas, has attracted the attention of several national and European institutions. It is thought that ENs can connect habitat patches and thus enable species to move across unsuitable areas. In Europe, however, ENs are proposed as an oversimplification of complex ecological concepts, and we maintain that they are of limited use for biodiversity conservation for several reasons. The ENs are species specific and operate on species-dependent scales. In addition, the information needed for their implementation is only available for a handful of species. To overcome these limitations, ENs have been proposed on a landscape scale (and for selected "focal" species), but there is no indication that the structural composition of core areas, corridors, and buffer areas could ensure the functional connectivity and improve the viability of more than a few species. The theory behind ENs fails to provide sufficient practical information on how to build them (e.g., width, shape, structure, content). In fact, no EN so far has been validated in practice (ensuring connectivity and increasing overall biodiversity conservation), and there are no signs that validation will be possible in the near future. In view of these limitations, it is difficult to justify spending economic and political resources on building systems that are at best working hypotheses that cannot be evaluated on a practical level.

Alternative targets and economic efficiency of selecting protected areas for biodiversity conservation in boreal forest

We examine the relative merits of alternative forest biodiversity targets, which give different weights to species according to their conservation status and abundance. A site selection framework is used for choosing the habitat-protection strategy that maximizes biodiversity subject to an upper bound on funding with six alternative conservation goals. By using Finnish data on old-growth forests, we found that alternative conservation goals yield different benefit-cost tradeoffs. Goals relying on complementarity between protected stands result in great marginal costs at a high conservation level. Therefore, under these conditions it may not be economically efficient to establish a large conservation network to protect all species in a given area. In contrast, a large conservation network is more likely to be justified when the habitat-protection strategy focuses on species abundance. The trade-offs between alternative objectives are explicitly measured by incrementally varying the weights given to the species. We found that the targets for all species representation and species abundance can largely be met simultaneously. Protecting red-listed species reduces overall species coverage and species abundance particularly at low budget levels.

Protected areas: a prism for a changing world

The centrality of protected areas in biodiversity conservation has not changed over the past three decades, but we now know that biodiversity conservation represents a much more complex and dynamic picture than was once thought. In contrast to the earlier primarily aesthetic motivation (and still valid in its own right), the role of protected areas in biodiversity conservation is now widely accepted. Internationally, their importance has been recognized by the Convention on Biological Diversity and by the creation of intergovernmental funding agencies such as the Global Environmental Facility. As I discuss here, the rate of creation of new protected areas has increased rapidly to meet the need for a protected representative set of the ecosystems of the world. But that is only the start of the task.

Brazilian Protected Areas

Abstract: Although Brazil's first park was established in 1937, the past two decades have witnessed an explosion of protected areas. Until 1989 federal parks and reserves were created by the Brazilian Forest Development Institute (IBDF) and the Special Secretariat for the Environment (SEMA). In 1989 SEMA and IBDF were united to form the Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA). A formal, unified system for federal, state, and municipal parks, the National System for Protected Areas, was made law in 2000. In 1976 IBDF drew up a biogeographical model for siting protected areas for biodiversity conservation in the Amazon, based on representation of phytogeographic regions. There are three ongoing initiatives to determine the location of new protected areas: (1) protected areas were recommended for the majority of 900 priority areas for biodiversity conservation identified in workshops held for Brazil's major biomes (1998–2000); (2) establishment of biodiversity corridors with parks and reserves as key elements; and (3) the creation of protected areas in the 23 Amazonian ecoregions identified by World Wildlife Fund—Brazil (the ARPA program). Federal and state strictly protected areas now number 478 and total 37,019,697 ha, and there are 436 sustainable‐use areas totalling 74,592,691 ha. Other categories of protected areas in Brazil include private natural heritage reserves (RPPNs), which are generally small but proving important for the conservation of restricted‐range and highly threatened species, and indigenous reserves, which are increasingly recognized as vital for biodiversity conservation because of their enormous size. Although Brazil has created an enormous number of protected areas over the last two decades, enormous challenges remain—not only for their administration and management—but also to protect the parks themselves as Brazil continues with its ambitious developmental programs for energy, infrastructure, industry, and agriculture.
