Landscape ecological planning for protected areas using spatial and temporal metrics

Mirkarimi, Hamed, hamed.mirkarimi@student.rmit.edu.au January 2007 (has links)
The natural characteristics of protected areas have changed for a variety of reasons through time. Changes in protected area landscapes can occur because of natural and/or cultural processes. Natural processes such as geomorphological disturbance and climatic condition can permanently and/or temporarily change the characteristics of the environment. In addition, changes in human needs, knowledge and activities are the cultural driving forces behind changing characteristics of landscape through time. These changes can be studied both spatially and temporally. Spatially, protected area landscape structures such as shape, size and location with respect to their neighbourhood context can be studied to describe landscape configuration. Temporally, landscape functions such as different geographical locations and land characteristics can be studied to determine the rate of temporal variability in landscape. Any changes in temporal characteristics may lead to changes in spatial characteristics of protected areas and vice versa. This thesis has developed a framework to enhance the landscape ecological planning approach with attention to changes in landscapes of protected areas. Considering landscape ecological concepts, this framework draws upon spatial and temporal characteristics of protected areas. Initially, a basic model of the landscape ecological approach to protected area planning and data requirements for landscape ecological planning was developed according to the concept of landscape ecological planning. In order to examine the model in the real world, the data requirements for landscape ecological planning were implemented using a case study method. The basic list of data required for landscape ecological planning was further developed through the case study approach by highlighting the importance of road metrics in the process of planning. In addition, the case study approach proved that spatial and temporal metrics can be used in the interpretation of spatial configuration and temporal variability of protected areas th rough a quantitative method. The framework was developed for three case studies in Iran and three case studies in Australia. A number of metrics were applied in order to quantify spatial and temporal aspects of the protected areas. A list of spatial and temporal criteria was developed to assist interpretation of area compaction, spatial fragmentation and temporal variability of protected areas. Using the criteria list, a new framework for spatial and temporal evaluation of protected areas has been developed. This can be used to determine spatial and temporal management issues of protected areas at the landscape scale. Then planning scenarios for spatial and temporal issues of protected areas at the landscape scale can be suggested. The developed framework has the potential to be applied to all protected areas even where detailed ecological data and information are not available. In addition, when all data required are available, the developed framework using spatial and temporal metrics has the potential to suggest a flexible zoning plan for protected areas.

Corredores ecológicos na reserva da biosfera do cinturão verde de São Paulo : Possibilidades e Conflitos / Ecological corridors system in São Paulo greenbelt biosphere reserve : conflicts and possibilities

Leite, Julia Rodrigues 12 July 2012 (has links)
Esta tese propõe o desenvolvimento de um sistema de corredores ecológicos para o setor Oeste da Reserva da Biosfera do Cinturão Verde (RBVC), área que foi delimitada seguindo a metodologia e os objetivos do Programa Homem e Biosfera, da UNESCO. A área estudada localiza-se na Região Metropolitana de São Paulo e possui diversos instrumentos legais, bem como algumas unidades de conservação que são de extrema importância para a manutenção dos serviços ambientais e ecológicos na região. Além disso, no entremeio dessa área, considerada como Zona Núcleo pela RBCV, existem fragmentos de vegetação típica de Mata Atlântica em diversos estágios sucessionais, sujeitos a maior fragmentação e perda de habitat, os quais ainda hoje possuem potencial para condução de fluxos ecológicos, tanto para biodiversidade como de recursos hídricos, todos fundamentais à preservação da vida silvestre. O objetivo do trabalho foi então apresentar e discutir os conflitos, as barreiras e oportunidades, avaliados por uma abordagem fundamentada em princípios de ecologia da paisagem e planejamento ecológico, de modo a manter e aumentar os fluxos ecológicos no setor estudado pelas indicações de soluções que possam minimizar os conflitos mais desafiadores. O desenho do sistema de corredores foi fundamentado em avaliações da paisagem natural, feitas por meio de matrizes e diversos mapas temáticos, que indicaram áreas com alta relevância para processos ecológicos e conectividade. A cada escala de avaliação do processo de planejamento, o desenho foi sendo aprimorado. Partiu-se de uma escala regional, até a definição do traçado do eixo principal e de cinco faixas indicativas secundárias que compõem o sistema estudado. Como resultado, foi obtido o traçado do sistema macro de corredores, estabelecendo-se áreas com maior potencial para a condução dos fluxos ecológicos e a definição dos principais conflitos e barreiras para o deslocamento de animais. Por fim, para o eixo principal e suas faixas indicativas secundárias, foi feita uma proposta de implementação dos corredores e sua integração com o tecido urbano, bem como apresentados alguns exemplos de infraestruturas, de maneira a implementar o desempenho dos importantes elos de conectividade que existem na área, podendo, assim, garantir uma maior eficiência da Reserva da Biosfera do Cinturão Verde de São Paulo. / Here is presented a proposal for the development of ecological corridors in the western sector of the São Paulo Metropolitan Region Green Belt Biosphere Reserve (RBCV). This area was delimitated under the methodology and goals of the UNESCO\'s Man and Biosphere Program. This area of the Metropolitan Region of São Paulo already have a number of legal instruments and some conservation areas that are of extreme importance for the maintenance of ecological services for the Region. Between them there are fragments of Atlantic Forest in various succession stages, but under stress of further fragmentation and loss of habitats. They are until now providing ecological flows, both for biodiversity and water resources, all fundamental to the wildlife preservation and quality of the human life. This thesis aims to present the ecological corridors system obtained, that leads to discuss the conflicts, barriers and opportunities that could be taken in order to keep and enhance the flows of the ecological system in this track of the RBCV, through a landscape ecology and planning approach, with the indication of the landscape designs that could deal with the most challenging of these conflicts.The system design was based on ecological assessments of the existing landscapes, indicating areas with the more high relevance for ecological processes and connectivity. Assessments were made through the use of matrix and thematic mapping overlays. In this process, we went from the scale of regional planning to a Master Plan of a local development, which originates from the main corridor swath. We got the general layout of corridors that came out from this design process. It indicated areas with the greatest potential for conducting ecological flows, defining the main conflicts and barriers to the movements of animals and finally, allowed the delineation of the possibilities for the corridors implementation and its integration with the urban fabric and the infrastructure network that cross the whole area. The ecological and land-use and landscape information gathered could be preliminarily processed to indicate the most significant natural elements that remains, and the new elements that should be added through landscape planning and design, that could be integrated in order to resolve the barriers and conflicts, that are restraining the performance of the crucial links that can give to the RBCV its needed full implementation.
