Department U.S. Department of Agriculture and published by CreateSpace. This book was released on 2015-01-02 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecoregional conservation planning for priority landbirds requires methods that explicitly link populations to habitat conditions at multiple scales. We developed Habitat Suitability Index (HSI) models to assess habitat quality for 40 priority bird species in the Central Hardwoods and West Gulf Coastal Plain/Ouachitas Bird Conservation Regions. The models incorporated both site and landscape environmental variables derived from one of six nationally consistent datasets: ecological subsections from the National Ecological Unit Hierarchy, National Land Cover Dataset, National Elevation Dataset, National Hydrography Dataset, State Soil Geographic Database, and Forest Inventory and Analysis data.

Book excerpt: Ecoregional conservation planning for priority landbirds requires methods that explicitly link populations to habitat conditions at multiple scales. We developed Habitat Suitability Index (HSI) models to assess habitat quality for 40 priority bird species in the Central Hardwoods and West Gulf Coastal Plain/Ouachitas Bird Conservation Regions. The models incorporated both site and landscape environmental variables derived from one of six nationally consistent datasets: ecological subsections from the National Ecological Unit Hierarchy, National Land Cover Dataset, National Elevation Dataset, National Hydrography Dataset, State Soil Geographic Database, and Forest Inventory and Analysis data. We initially defi ned potential habitat for each species from unique landform, landcover, and successional age class combinations. Species-specific environmental variables identifi ed from the literature were used to refi ne initial habitat estimates. We verified models by comparing subsection-level HSI scores and Breeding Bird Survey (BBS) abundance via Spearman rank correlation. To validate models, we developed generalized linear models that predicted BBS abundance as a function of HSI score and Bird Conservation Region. We considered models that included a significant (P [less than or equal to] 0.100) positive coefficient on the BBS predictor to be valid and useful for conservation planning.

Available in PDF, EPUB and Kindle. Book excerpt: Selected by Forbes.com as one of the 12 best books about birds and birding in 2016 This much-anticipated third edition of the Handbook of Bird Biology is an essential and comprehensive resource for everyone interested in learning more about birds, from casual bird watchers to formal students of ornithology. Wherever you study birds your enjoyment will be enhanced by a better understanding of the incredible diversity of avian lifestyles. Arising from the renowned Cornell Lab of Ornithology and authored by a team of experts from around the world, the Handbook covers all aspects of avian diversity, behaviour, ecology, evolution, physiology, and conservation. Using examples drawn from birds found in every corner of the globe, it explores and distills the many scientific discoveries that have made birds one of our best known - and best loved - parts of the natural world. This edition has been completely revised and is presented with more than 800 full color images. It provides readers with a tool for life-long learning about birds and is suitable for bird watchers and ornithology students, as well as for ecologists, conservationists, and resource managers who work with birds. The Handbook of Bird Biology is the companion volume to the Cornell Lab’s renowned distance learning course, Ornithology: Comprehensive Bird Biology.

This book was released on 2011-08-03 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume addresses a rising concern among natural resource scientists and management professionals about decline of the many plant and animal species associated with early-successional habitats, especially within the Central Hardwood Region of the USA. These open habitats, with herbaceous, shrub, or young forest cover, are disappearing as abandoned farmland, pastures, and cleared forest patches return to forest. There are many questions about “why, what, where, and how” to manage for early successional habitats. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address questions on such topics as wildlife, water, carbon sequestration, natural versus managed disturbance, future scenarios, and sustainable creation and management of early successional habitat in a landscape context.

Book excerpt: A review and synthesis of existing information were used to develop a model for evaluating wintering habitat quality for the northern pintail along the Gulf of Mexico. The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimum habitat). Habitat suitability indices are designed for use with the Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.

This book was released on 1991 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat Suitability Index (HSI) models were developed to assess the sensitivity of wildlife to habitat perturbations. Because most models consider a single species, their generality is limited. We evaluate the feasibility of combining such models for species occupying similar habitats to create more general models of wildlife-habitat relations. We base our evaluation on an analysis of HSI models for 16 forest bird species. Standardization of both measurement and definition of minimum area and life requisites is necessary to permit model aggregation. Validation should focus especially on assumptions about factors limiting population density and productivity and about how SI values are combined in equations to produce overall HSI values. We emphasize the importance of manipulative field experiments and model sensitivity analyses in such validation activities. We compare the 'bottom-up' approach, in which individual models are aggregated to develop more general models, to the 'top-down' approach of beginning with broad statements about a system and adding in detail only as it is needed. Any attempts to model wildlife-habitat interrelations, whether they apply to single species or suites of species, must also consider the importance of the spatial and temporal scales of resolution used and must treat habitat units as part of a larger landscape mosaic.
