A Landscape Atlas of the Chesapeake Bay Watershed


Book Description

A "landscape" approach is needed to assess ecological conditions over such a large area. Some of the most important aspects of environmental change occur at the broad spatial scale of whole landscapes, and these cannot always be detected in small-scale studies. Because landscape patterns and trends are the context for the condition of embedded ecosystems, such information has proven useful for both local and regional assessments.




An Ecological Assessment of the United States Mid-Atlantic Region


Book Description

"The assessment was done using measurements derived from satellite imagery and spatial data bases. The information presented in this atlas is intended to help the reader visualize and understand the changing conditions across the region and how the pattern of conditions can be used as a context for community-level situations. This atlas was developed as part of the Environmental Monitoring and Assessment Program (EMAP) and is part of a larger, multi-organizational effort to assess environmental condition in the mid-Atlantic region."--From the publisher.




Chesapeake Gardening and Landscaping


Book Description

What if, one step at a time, we could make our gardens and landscapes more eco-friendly? Barbara W. Ellis's colorful, comprehensive guide shows homeowners, gardeners, garden designers, and landscapers how to do just that for the large and beautiful Chesapeake Bay watershed region. This area includes Maryland, Virginia, Delaware, Washington, D.C., and part of West Virginia (translating to portions of USDA Zones 6, 7, and 8). Here, mid-Atlantic gardeners, from beginners to advanced, will find the essential tools for taking steps to make their gardens part of the solution through long-term planning and planting. The guide is built from the ground up around six simple but powerful principles that anyone can use: * Reduce lawn * Build plant diversity * Grow native plants * Manage water runoff * Welcome wildlife * Garden wisely Included are detailed instructions for assessing and designing your particular garden or landscape site; choosing and caring for trees, shrubs, vines, ground covers, and flowers; and succeeding with such conditions as shade or poor soil. From rain gardens to woodland gardens, meadow gardens to wildlife gardens, and much more, this indispensable guide features more than 300 color photographs.




Landscape Ecology in Theory and Practice


Book Description

An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.




ENVIRONMENTAL INDICES : SYSTEMS ANALYSIS APPROACH - Volume I


Book Description

Environmental Indices: Systems Analysis Approach examines the theoretical development of environmental indices and their practical application. Indicators can be powerful tools in guiding data and information collection processes, and careful development will lead to more focused and cost-effective global monitoring and observing systems at international level. The authorship is drawn from a group of internationally distinguished scientists and researches who are actively working towards a comprehensive set of tools and protocols such as simulation models, fuzzy clustering analysis and GIS methodologies that will lead to the development of meaningful environmental indices. This book will be a vital reference work for students, teachers and researches, together with policy makers, planners and all professional involved in development programs.




The Maryland Amphibian and Reptile Atlas


Book Description

The definitive resource for finding, identifying, and conserving Maryland’s amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity—and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.
