[EN] Enforcement of rural policy measures within National Parks may have a particular importance as they may contribute to reach socioeconomic objectives devised for such areas. So this paper approaches as case study the application of a relevant rural development measure in the Northumberland National Park (NNP) –England, North East— over the period 2000-2008 in order to explore whether NNP makes any difference in terms of enforcing rural policy measures. The main research findings indicate that NNP may have some sort of positive impact on rural development, but support relying on tourism monoculture may be a background reason for undesired negative consequences.

Amphibian declines and extinctions have been documented around the world, often in protected natural areas. Concern for this trend has prompted the U.S. Geological Survey and the National Park Service to document all species of amphibians that occur within U.S. National Parks and to search for any signs that amphibians may be declining. This study, an inventory of amphibian species in Big Cypress National Preserve, was conducted from 2002 to 2003. The goals of the project were to create a georeferenced inventory of amphibian species, use new analytical techniques to estimate proportion of sites occupied by each species, look for any signs of amphibian decline (missing species, disease, die-offs, and so forth.), and to establish a protocol that could be used for future monitoring efforts. Several sampling methods were used to accomplish these goals. Visual encounter surveys and anuran vocalization surveys were conducted in all habitats throughout the park to estimate the proportion of sites or proportion of area occupied (PAO) by each amphibian species in each habitat. Opportunistic collections, as well as limited drift fence data, were used to augment the visual encounter methods for highly aquatic or cryptic species. A total of 545 visits to 104 sites were conducted for standard sampling alone, and 2,358 individual amphibians and 374 reptiles were encountered. Data analysis was conducted in program PRESENCE to provide PAO estimates for each of the anuran species. All of the amphibian species historically found in Big Cypress National Preserve were detected during this project. At least one individual of each of the four salamander species was captured during sampling. Each of the anuran species in the preserve was adequately sampled using standard herpetological sampling methods, and PAO estimates were produced for each species of anuran by habitat. This information serves as an indicator of habitat associations of the species and relative abundance of sites occupied, but it will also be useful as a comparative baseline for future monitoring efforts. In addition to sampling for amphibians, all encounters with reptiles were documented. The sampling methods used for detecting amphibians are also appropriate for many reptile species. These reptile locations are included in this report, but the number of reptile observations was not sufficient to estimate PAO for reptile species. We encountered 35 of the 46 species of reptiles believed to be present in Big Cypress National Preserve during this study, and evidence exists of the presence of four other reptile species in the Preserve. This study found no evidence of amphibian decline in Big Cypress National Preserve. Although no evidence of decline was observed, several threats to amphibians were identified. Introduced species, especially the Cuban treefrog (Osteopilus septentrionalis), are predators and competitors with several native frog species. The recreational use of off-road vehicles has the potential to affect some amphibian populations, and a study on those potential impacts is currently underway. Also, interference by humans with the natural hydrologic cycle of south Florida has the potential to alter the amphibian community. Continued monitoring of the amphibian species in Big Cypress National Preserve is recommended. The methods used in this study were adequate to produce reliable estimates of the proportion of sites occupied by most anuran species, and are a cost-effective means of determining the status of their populations.

Na perspectiva ambiental, o Parque Nacional da Serra dos Órgãos (PARNASO) é o Parque Nacional mais pesquisado no Brasil e configura-se como uma importante Unidade de Conservação inserida no estado do Rio de Janeiro, devido à sua importância ambiental para o estado. Localizado em quatro municípios da região serrana: Teresópolis, Petrópolis, Magé e Guapimirim foi constatado que essa área tem passado por alguns problemas, relativamente recentes, de ocupação desordenada devido à expansão urbana em sua vizinhança caracterizada por pressão antrópica. Através do processamento de imagens digitais, mais especificamente as etapas de segmentação e classificação, foi possível ilustrar o processo de ocupação humana por meio de documentos cartográficos. Além de estes processos possibilitarem a geração de mapas de uso da Terra e cobertura vegetal, com o intuito de auxiliar e dar fomento à execução de atividades, o mapeamento digital configura-se numa importante ferramenta para a análise ambiental, contribuindo para o posterior zoneamento da área de estudo. Adotaram-se classes temáticas de uso e ocupação da Terra com o propósito de permitir a classificação das imagens digitais trabalhadas. São elas: afloramento rochoso, área urbana, agricultura e vegetação. Estudos foram feitos no sentido de indicar e explorar as funcionalidades das ferramentas SPRING e DEFINIENS e resultados foram comparados a partir do uso de imagens LANDSAT, CBERS, SPOT e IKONOS chegando-se a resultados de que no sistema SPRING, os melhores parâmetros a serem escolhidos foram similaridade 10 e área 400. Já para o sistema DEFINIENS, constatou-se que o processo de segmentação multinível permitiu o alcance de resultados mais rápidos, do ponto de vista computacional, do que o processo de segmentação único utilizado normalmente entre os sistemas de processamento de imagens digitais como o SPRING. Já sob a ótica do processo de classificação de imagens, a pesquisa constituiu em avaliar este mecanismo por meio de dois indicadores: o de exatidão/acurácia e o índice Kappa. Neste sentido, observaram-se tendências de melhores resultados no sistema SPRING.

Scientific and anecdotal observations during recent decades have suggested that the structure and function of the coral reef ecosystems around St. John, U.S. Virgin Islands have been impacted adversely by a wide range of environmental stressors. Major stressors included the mass die-off of the long-spined sea urchin (Diadema antillarum) in the early 1980s, a series of hurricanes (David and Frederick in 1979, and Hugo in 1989), overfishing, mass mortality of Acropora species and other reef-building corals due to disease and several coral bleaching events. In response to these adverse impacts, the National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment, Biogeography Branch (CCMA-BB) collaborated with federal and territorial partners to characterize, monitor, and assess the status of the marine environment around the island from 2001 to 2012. This 13-year monitoring effort, known as the Caribbean Coral Reef Ecosystem Monitoring Project (CREM), was supported by the NOAA Coral Reef Conservation Program as part of their National Coral Reef Ecosystem Monitoring Program. This technical memorandum contains analysis of nine years of data (2001-2009) from in situ fish belt transect and benthic habitat quadrat surveys conducted in and around the Virgin Islands National Park (VIIS) and the Virgin Islands Coral Reef National Monument (VICR). The purpose of this document is to: 1) Quantify spatial patterns and temporal trends in (i) benthic habitat composition and (ii) fish species abundance, size structure, biomass, and diversity; 2) Provide maps showing the locations of biological surveys and broad-scale distributions of key fish and benthic species and assemblages; and 3) Compare benthic habitat composition and reef fish assemblages in areas under NPS jurisdiction with those in similar areas not managed by NPS (i.e., outside of the VIIS and VICR boundaries). This report provides key information to help the St. John management community and others understand the impacts of natural and man-made perturbations on coral reef and near-shore ecosystems. It also supports ecosystem-based management efforts to conserve the region’s coral reef and related fauna while maintaining the many goods and ecological services that they offer to society.

NOAA’s National Centers for Coastal Ocean Science Biogeography Branch has mapped and characterized large portions of the coral reef ecosystems inside the U.S. coastal and territorial waters, including the U.S. Caribbean. The complementary protocols used in these efforts have enabled scientists and managers to quantitatively and qualitatively compare marine ecosystems in tropical U.S. waters. The Biogeography Branch used similar protocols to generate new benthic habitat maps for Fish Bay, Coral Bay and the St. Thomas East End Reserve (STEER). While this mapping effort marks the third time that some of these shallow-water habitats (≤40 m) have been mapped, it is the first time that nearly 100% of the seafloor has been characterized in each of these areas. It is also the first time that high resolution imagery describing seafloor depth has been collected in each of these areas. Consequently, these datasets provide new information describing the distribution of coral reef ecosystems and serve as a spatial baseline for monitoring change in the Fish Bay, Coral Bay and the STEER. Benthic habitat maps were developed for approximately 64.3 square kilometers of seafloor in and around Fish Bay, Coral Bay and the STEER. Twenty seven percent (17.5 square kilometers) of these habitat maps describe the seafloor inside the boundaries of the STEER, the Virgin Islands National Park and the Virgin Islands Coral Reef National Monument. The remaining 73% (46.8 square kilometers) describe the seafloor outside of these MPA boundaries. These habitat maps were developed using a combination of semi-automated and manual classification methods. Habitats were interpreted from aerial photographs and LiDAR (Light Detection and Ranging) imagery. In total, 155 distinct combinations of habitat classes describing the geology and biology of the seafloor were identified from the source imagery.

Coral reef ecosystems of the Virgin Islands Coral Reef National Monument, Virgin Islands National Park and the surrounding waters of St. John, U.S. Virgin Islands are a precious natural resource worthy of special protection and conservation. The mosaic of habitats including coral reefs, seagrasses and mangroves, are home to a diversity of marine organisms. These benthic habitats and their associated inhabitants provide many important ecosystem services to the community of St. John, such as fishing, tourism and shoreline protection. However, coral reef ecosystems throughout the U.S. Caribbean are under increasing pressure from environmental and anthropogenic stressors that threaten to destroy the natural heritage of these marine habitats. Mapping of benthic habitats is an integral component of any effective ecosystem-based management approach. Through the implementation of a multi-year interagency agreement, NOAA’s Center for Coastal Monitoring and Assessment - Biogeography Branch and the U.S. National Park Service (NPS) have completed benthic habitat mapping, field validation and accuracy assessment of maps for the nearshore marine environment of St. John. This work is an expansion of ongoing mapping and monitoring efforts conducted by NOAA and NPS in the U.S. Caribbean and replaces previous NOAA maps generated by Kendall et al. (2001) for the waters around St. John. The use of standardized protocols enables the condition of the coral reef ecosystems around St. John to be evaluated in context to the rest of the Virgin Island Territories and other U.S. coral ecosystems. The products from this effort provide an accurate assessment of the abundance and distribution of marine habitats surrounding St. John to support more effective management and conservation of ocean resources within the National Park system. This report documents the entire process of benthic habitat mapping in St. John. Chapter 1 provides a description of the benthic habitat classification scheme used to categorize the different habitats existing in the nearshore environment. Chapter 2 describes the steps required to create a benthic habitat map from visual interpretation of remotely sensed imagery. Chapter 3 details the process of accuracy assessment and reports on the thematic accuracy of the final maps. Finally, Chapter 4 is a summary of the basic map content and compares the new maps to a previous NOAA effort. Benthic habitat maps of the nearshore marine environment of St. John, U.S. Virgin Islands were created by visual interpretation of remotely sensed imagery. Overhead imagery, including color orthophotography and IKONOS satellite imagery, proved to be an excellent source from which to visually interpret the location, extent and attributes of marine habitats. NOAA scientists were able to accurately and reliably delineate the boundaries of features on digital imagery using a Geographic Information System (GIS) and fi eld investigations. The St. John habitat classification scheme defined benthic communities on the basis of four primary coral reef ecosystem attributes: 1) broad geographic zone, 2) geomorphological structure type, 3) dominant biological cover, and 4) degree of live coral cover. Every feature in the benthic habitat map was assigned a designation at each level of the scheme. The ability to apply any component of this scheme was dependent on being able to identify and delineate a given feature in remotely sensed imagery.

The Meteorological Section at the scientific camp 2009–2010 conducted a series of meteorological measurements in the region of Biała Góra. The exploration area is located about 2 km east of Międzyzdroje, at the research station of the AMU Faculty of Geographical and Geological Sciences. Members of the section made measurements in the six selected points. The location of points had to reflect the specifics of the area (from the beach to the car park at the research station). The section focused on three basic measurements: air temperature (2009–2010), relative humidity (2009–2010) and atmospheric pressure (2009). This article aims to analyse a topoclimate section of cliff coast in the Wolin National Park. The compilation recognised the impact of various land surfaces, sea and altitude on the variability of air temperature and relative humidity. It notes the varied course of the daily meteorological elements analysed, which is directly related to the value of radiation balance dependent upon the intensity of direct solar radiation. In this article, particular emphasis is applied to the analysis of temperature amplitudes and humidity at different measuring points.

The introduction of national parks to Scotland represents a significant shift in the evolution of protected area management within the UK. Although the National Parks (Scotland) Act 2000 adopts the established national park aims of conservation and recreation, provisions are also made for advancing notions of sustainable development. This paper provides an assessment of the degree to which the Scottish national park model is likely to enable the realisation of multiple national park objectives. Five key areas are considered for analysis. These relate to management aims, institutional arrangements, implementation, democratic accountability and funding. The evaluation reveals that whilst management provisions have been established in accordance with international sustainable development guidelines, a number of concerns relating to operational processes remain.

This paper provides a contemporary examination of policy making and participatory practice in the context of devolving governance in the UK. The paper takes Northern Ireland as its focus and is particularly timely considering the context of devolved governance, the ongoing transition from conflict to relative peace and the potential for rejuvenating democracy through participatory
governance. The paper concentrates on one particular policy process, namely the attempted designation of a national park in the Mournes Area of Outstanding Natural Beauty. A thematic analysis of qualitative data is drawn upon to analyse the structural factors that framed the policymaking process, in particular the role of power in determining how consultation processes were 2 initiated, designed and undertaken. Using Lukes’ model) as an analytical framework, power is shown to manifest at multiple levels within the policy-making process to influence policy outcomes. The paper reveals how the persistence of a top-down approach to policy development combined with a highly parochial political outlook undermined attempts to designate a Mourne National Park. The paper concludes that, given the immaturity of recently devolved government in
Northern Ireland, in this instance, the democratising intentions of devolved governance have not been met. This has implications for Northern Ireland’s recent reform of public administration which devolves certain planning powers to local authority level and the management of the internationally significant Mournes landscape.
