Available in PDF, EPUB and Kindle. Book excerpt: Geographic Information Systems (GIS) provide a powerful tool for the investigation of species-habitat relationships and the development of wildlife management and conservation programs. However, the relative ease of data manipulation and analysis using GIS, associated landscape metrics packages, and sophisticated statistical tests may sometimes cause investigators to overlook important species-habitat functional relationships. Additionally, underlying assumptions of the study design or technology may have unrecognized consequences. This volume examines how initial researcher choices of image resolution, scale(s) of analysis, response and explanatory variables, and location and area of samples can influence analysis results, interpretation, predictive capability, and study-derived management prescriptions. Overall, most studies in this realm employ relatively low resolution imagery that allows neither identification nor accurate classification of habitat components. Additionally, the landscape metrics typically employed do not adequately quantify component spatial arrangement associated with species occupation. To address this latter issue, the authors introduce two novel landscape metrics that measure the functional size and location in the landscape of taxon-specific ‘solid’ and ‘edge’ habitat types. Keller and Smith conclude that investigators conducting GIS-based analyses of species-habitat relationships should more carefully 1) match the resolution of remotely sensed imagery to the scale of habitat functional relationships of the focal taxon, 2) identify attributes (explanatory variables) of habitat architecture, size, configuration, quality, and context that reflect the way the focal taxon uses the subset of the landscape it occupies, and 3) match the location and scale of habitat samples, whether GIS- or ground-based, to corresponding species’ detection locations and scales of habitat use.

This book was released on 2012-08-01 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this book is an attempt to quantify the spatial pattern of landscape using various spatial pattern metrics & to develop an approach for monitoring the impact of LULC dynamics on wildlife habitat quality in the Betla National park. Satellite data of the year 1990 and 2000 were used to prepare LULC maps though hybrid classification. Different landscape metrics such as diversity, contagion, fractal dimension, fragmentation and connectivity, calculated using ArcInfo software & computer program written in C, were used to characterize the change in landscape pattern. Two indices namely habitat quality index (HQI) & overall suitability index were developed for quantitative assessment of the habitat quality. The values of HQI were found to be 0.4051 and 0.3762 respectively for the year 1990 and 2000. It indicates a deterioration of about 7.14% in habitat quality due to the landscape dynamics during study period. Despite of intense landscape dynamics, only a marginal deterioration was observed in forest habitat quality due to proper management practices and restoration measurements taken by the forest officials to nullify the negative effects of increased LULC dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: With the rapid advancement and popularity of geospatial technologies such as location-aware smartphones, mobile maps, etc., average citizens nowadays can easily contribute georeferenced wildlife data (e.g., wildlife sightings). Due to the wide spread of human settlements and lengthy living histories of citizens in their local areas, citizen-contributed wildlife data could cover large geographic areas over long time spans. Citizen science thus provides great opportunities for collecting wildlife data of extensive spatiotemporal coverage for wildlife habitat assessment. However, citizen-contributed wildlife data may be subject to data quality issues, for example, imprecise spatial position and biased spatial coverage. These issues need to be accounted for when using citizen-contributed data for wildlife habitat assessment. Geovisualization and geospatial analysis capabilities provisioned by geographic information systems (GISs) can be adopted to tackle such data quality issues. This chapter offers an overview of citizen science as a means of collecting wildlife data, the roles of GIS to tackle the data quality issues, and the integration of citizen science and GIS for wildlife habitat assessment. A case study of habitat assessment for the black-and-white snub-nosed monkey (Rhinopithecus bieti) using R. bieti sightings elicited from local villagers in Yunnan, China, is presented as a demonstration.

Available in PDF, EPUB and Kindle. Book excerpt: In our surrounding large number of species have been facing serious problem due to disturbance on their habitat. While these species play key role in environment but lack of adequate study on such species made them a vulnerable species. Due to puny information on their ecology, they are not getting priorities from conservationist that's why, they have to face myriad number of threats. In this context, this book helps to provide field based knowledge for the quantification of population, habitat and threats of a wild species. Similarly, this book explains a process to link remote sensing, GIS and people's perception in wildlife research. The main aim of this book is to explore the detail ecology, population, habitat and conservation issue of Lesser Adjutant Stork; a vulnerable species identified by IUCN in eastern lowlands of Nepal.

Download or read book Models for Planning Wildlife Conservation in Large Landscapes written by Joshua Millspaugh and published by Academic Press. This book was released on 2011-04-28 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: A single-resource volume of information on the most current and effective techniques of wildlife modeling, Models for Planning Wildlife Conservation in Large Landscapes is appropriate for students and researchers alike. The unique blend of conceptual, methodological, and application chapters discusses research, applications and concepts of modeling and presents new ideas and strategies for wildlife habitat models used in conservation planning. The book makes important contributions to wildlife conservation of animals in several ways: (1) it highlights historical and contemporary advancements in the development of wildlife habitat models and their implementation in conservation planning; (2) it provides practical advice for the ecologist conducting such studies; and (3) it supplies directions for future research including new strategies for successful studies.Intended to provide a recipe for successful development of wildlife habitat models and their implementation in conservation planning, the book could be used in studying wildlife habitat models, conservation planning, and management techniques. Additionally it may be a supplemental text in courses dealing with quantitative assessment of wildlife populations. Additionally, the length of the book would be ideal for graduate student seminar course.Using wildlife habitat models in conservation planning is of considerable interest to wildlife biologists. With ever tightening budgets for wildlife research and planning activities, there is a growing need to use computer methods. Use of simulation models represents the single best alternative. However, it is imperative that these techniques be described in a single source. Moreover, biologists should be made aware of alternative modeling techniques. It is also important that practical guidance be provided to biologists along with a demonstration of utility of these procedures. Currently there is little guidance in the wildlife or natural resource planning literature on how best to incorporate wildlife planning activities, particularly community-based approaches. Now is the perfect time for a synthestic publication that clearly outlines the concepts and available methods, and illustrates them. Only single resource book of information not only on various wildlife modeling techniques, but also with practical guidance on the demonstrated utility of each based on real-world conditions. Provides concepts, methods and applications for wildlife ecologists and others within a GIS context. Written by a team of subject-area experts

This book was released on 1998-04-28 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical habitats may contain more than a third of the world's plant and animal species; Costa Rica alone is home to one of the highest levels of biodiversity per unit area in the world, and stands at center stage in worldwide conservation efforts. Within such regions, the use of state-of-the-art digital mapping technologies—sophisticated techniques that are relatively inexpensive and accessible—represents the future of conservation planning and policy. These methods, which employ satellites to obtain visual data on landscapes, allow environmental scientists to monitor encroachment on indigenous territories, trace park boundaries through unmarked wilderness, and identify wildlife habitats in regions where humans have limited access. Focusing on the rich biodiversity of Costa Rica, the contributors demonstrate the use of geographic information systems (GIS) to enhance conservation efforts. They give an overview of the spatial nature of conservation and management and the current status of digital mapping in Costa Rica; a review of the basic principles behind digital mapping technologies; a series of case studies using these technologies at a variety of scales and for a range of conservation and management activities; and the results of the Costa Rican gap analysis project. GIS Methodologies for Developing Conservation Strategies provides powerful tools for those involved in decision-making about the natural environment, particularly in developing nations like Costa Rica where such technologies have not yet been widely adopted. For specialists in such areas as geography, conservation biology, and wildlife and natural resource management, the combination of conceptual background and case examples make the book a crucial addition to the literature.

Download or read book Predictive Species and Habitat Modeling in Landscape Ecology written by C. Ashton Drew and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most projects in Landscape Ecology, at some point, define a species-habitat association. These models are inherently spatial, dealing with landscapes and their configurations. Whether coding behavioral rules for dispersal of simulated organisms through simulated landscapes, or designing the sampling extent of field surveys and experiments in real landscapes, landscape ecologists must make assumptions about how organisms experience and utilize the landscape. These convenient working postulates allow modelers to project the model in time and space, yet rarely are they explicitly considered. The early years of landscape ecology necessarily focused on the evolution of effective data sources, metrics, and statistical approaches that could truly capture the spatial and temporal patterns and processes of interest. Now that these tools are well established, we reflect on the ecological theories that underpin the assumptions commonly made during species distribution modeling and mapping. This is crucial for applying models to questions of global sustainability. Due to the inherent use of GIS for much of this kind of research, and as several authors’ research involves the production of multicolored map figures, there would be an 8-page color insert. Additional color figures could be made available through a digital archive, or by cost contributions of the chapter authors. Where applicable, would be relevant chapters’ GIS data and model code available through a digital archive. The practice of data and code sharing is becoming standard in GIS studies, is an inherent method of this book, and will serve to add additional research value to the book for both academic and practitioner audiences.

Donaldson and published by . This book was released on 2006 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: As important habitats are being lost to human development, transportation agencies are facing increased expectations that their road projects avoid or minimize further habitat destruction and adverse effects on wildlife populations. Wildlife linkage or landscape corridor analyses are being conducted in an increasing number of states, and more transportation agencies are using this information during the planning of proposed road projects. The Virginia Department of Conservation and Recreation's Natural Heritage Program is creating a GIS tool, the Virginia Natural Landscape Assessment (VANLA), that identifies large patches of natural land cover (habitat cores) and the habitat linkages connecting these areas (landscape corridors). This analysis can be integrated into the Virginia Department of Transportation's (VDOT) existing GIS applications for access by staff involved with transportation planning and environmental scoping activities. Analyzing a proposed project in the early stages of project development would allow VDOT to identify important natural resource areas and habitat corridors to avoid or for which mitigation may be appropriate or necessary. This can result in fewer project delays, promote collaboration between VDOT and state natural resource and regulatory agencies, and meet the directives of the new habitat conservation provision in SAFETEA-LU, the federal transportation legislation. In addition, basing particular project decisions on a project's location relative to a habitat corridor can decrease the risk of costly animal-vehicle collisions.

This book was released on 2015-02-14 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of studies on wildlife-habitat relationships have provided important insights into the habitat requisites for many game and nongame species. Information gained from these studies has been used to develop wildlife habitat models (e.g., habitat suitability index [HSI] models; U.S. Fish and Wildlife Serv. 1980, 1981), the application of which enables assessment of current habitat conditions and predictions of how habitat suitability may change under management (e.g., habitat evaluation procedures; U.S. Fish and Wildlife Serv. 1980, 1981). Radio-telemetry (Rodgers 2001) and computing (e.g., geographic information systems; GIS) technology have enhanced our understanding of wildlifehabitat relationships, especially with regard to wildlife spatial ecology.
