The rapidly increasing global population has dramatically increased the demands for natural resources and has caused significant changes in quantity and quality of natural resources. To achieve sustainable resource management, it is essential to obtain insightful guidance from emerging disciplines such as landscape ecology. This text addresses the links between landscape ecology and natural resource management. These links are discussed in the context of various landscape types, a diverse set of resources and a wide range of management issues. A large number of landscape ecology concepts, principles and methods are introduced. Critical reviews of past management practices and a number of case studies are presented. This text provides many guidelines for managing natural resources from a landscape perspective and offers useful suggestions for landscape ecologists to carry out research relevant to natural resource management. In addition, it will be an ideal supplemental text for graduate and advanced undergraduate ecology courses.

Abstract: Studies on forest loss and fragmentation have found that proportion of forest cover, forest patch size, shape and isolation, and matrix quality affect mammal species richness and occurrence in tropical landscapes. However, how do these characteristics influence mammal species in a landscape like Hong Kong where the deforestation process has been lengthy and interrupted by waves of forest contraction and expansion, and that has resulted in a mammal community of habitat generalists? We have a good understanding of the mammal distributions in Hong Kong; however, we know very little about the factors affecting this. This study investigated if forest at the patch- and landscape-scale influences the species richness and relative abundance of mammal species in Hong Kong. Camera trapping data from a separate, Hong Kong-wide study, undertaken from 2000-2003 (which recorded 20 non-flying mammals species), was used to evaluate the influence of patch metrics (patch size/area and shape) and landscape attributes (forest cover, number of forest patches, mean inter-patch isolation distance, matrix quality and urban developed area cover) at two spatial scales (100 hectare buffer and 450 hectare buffer) on mammal species richness and relative abundance (using occurrence index). Patch metrics were measured from 32 focal patches and landscape attributes were measured from 21 landscape buffers, across Hong Kong. At the patch-scale, patch shape and size/area were not found to have an influence on extant and common mammal species richness or relative abundance. This is probably because the most sensitive species have already disappeared from Hong Kong, and the wide range of habitats in the matrix may be sufficient for the extant mammal species to survive and reproduce outside of forest patches. At the landscape-scale, Melogale moschata, Felis catus and Prionailurus bengalensis were associated with landscape buffers comprising a lower patch number and reduced patch isolation, indicating that whilst not forest obligates, these species may have some reliance on forest. In addition, the study found greater records of presence in forest habitat compared to matrix habitat for Hystrix brachyura, Macaca mulatta, Paguma larvata, Viverricula indica, Sus scrofa and Prionailurus bengalensis. Therefore, while the mammal species are likely to be able to use the matrix for survival, forest habitat is still likely to be important in Hong Kong for its terrestrial mammals. Matrix quality was not found to influence mammal species richness or relative abundance. The use of the matrix, which predominantly comprises natural habitats (e.g. shrubland and grassland) in Hong Kong, by the mammal generalists may help to mitigate the negative effects of forest fragmentation. The results of the study appeared to be strongly influenced by the geographic locations of the forest patches and landscape buffers. As the obvious patterns associated with patch metrics and landscape attributes were not strongly apparent, further examination of the mammal communities, particularly within different regions may be necessary. In addition given the rarity of some of the 'outlier' species omitted from the analyses, association or possible reliance on forest habitat/patches may make them more vulnerable. Therefore, further assessment of rare species is recommended. Subjects:

The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.

While the research and management of wildlife has traditionally emphasised studies at smaller scales, it is now acknowledged that larger, landscape-level patterns strongly influence demographic processes in wild animal species. This book is the first to provide the conceptual basis for learning how larger scale patterns and processes can influence the biology and management of wildlife species. It is divided into three sections: Underlying Concepts, Landscape Metrics and Applications and Large Scale Management.

Area sensitivity of North American grassland birds is a significant conservation concern; yet, its causes are not known. I used point count data from 20 tall-grass prairie patches in Southern Manitoba to assess the relative importance of patch size, edge proximity, and landscape composition on the densities and species richness of grassland songbirds. The degree to which the landscape surrounding point count plots was open, as opposed to forested or urban, had a positive effect on species richness and the densities of most focal species, and was more important than patch size, edge proximity, or habitat amount. These results suggest that landscape openness, not patch size (with which it is usually correlated) drives area sensitivity. Small grassland patches embedded in open landscapes are less susceptible to area sensitivity and may be of high conservation value for grassland birds.

Habitat loss and degradation that comes as a result of human activity is the single biggest threat to biodiversity in the world today. Habitat Fragmentation and Landscape Change is a groundbreaking work that brings together a wealth of information from a wide range of sources to define the ecological problems caused by landscape change and to highlight the relationships among landscape change, habitat fragmentation, and biodiversity conservation. The book: synthesizes a large body of information from the scientific literature considers key theoretical principles for examining and predicting effects examines the range of effects that can arise explores ways of mitigating impacts reviews approaches to studying the problem discusses knowledge gaps and future areas for research and management Habitat Fragmentation and Landscape Change offers a unique mix of theoretical and practical information, outlining general principles and approaches and illustrating those principles with case studies from around the world. It represents a definitive overview and synthesis on the full range of topics that fall under the widely used but often vaguely defined term "habitat fragmentation."
