This document is a cooperative effort among fifteen Federal agencies and partners to produce a common reference on stream corridor restoration. It responds to a growing national and international interest in restoring stream corridors.
The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.
The flagship publication of the National Parks Conservation Association, National Parks Magazine (circ. 340,000) fosters an appreciation of the natural and historic treasures found in the national parks, educates readers about the need to preserve those resources, and illustrates how member contributions drive our organization's park-protection efforts. National Parks Magazine uses images and language to convey our country's history and natural landscapes from Acadia to Zion, from Denali to the Everglades, and the 387 other park units in between.
IUCN's Protected Areas Management Categories, which classify protected areas according to their management objectives, are today accepted as the benchmark for defining, recording, and classifying protected areas. They are recognized by international bodies such as the United Nations as well as many national governments. As a result, they are increasingly being incorporated into government legislation. These guidelines provide as much clarity as possible regarding the meaning and application of the Categories. They describe the definition of the Categories and discuss application in particular biomes and management approaches.
The authors trace the evolution of the Western garden from the first plots cultivated for pleasure in the Middle East to today's diverse green spaces that challenge traditional ideas about what constitutes a garden. They examine the changing attitude toward nature--as something to be dominated or embraced, ordered or allowed to range freely, exploited or conserved. Examples of the highly prescribed hortus conclusus or enclosed spaces of the Middle Ages are found in the Italian Renaissance gardens and the symmetries of Versailles and Les Tuileries. After the rise of Romanticism in the late eighteenth century, English gardeners such as William Kent and "Capability" Brown embraced the concept that nature should prevail over man's manipulation of it and created gardens that broke through traditional enclosures. A century later, while the American West witnessed both the conquering spirit of the homesteaders and the first stirrings of the conservation movement, urban parks and gardens were created as oases to which all people had access. The book concludes with a look at contemporary gardens, where efforts to reclaim landscapes and repurpose crumbling infrastructure are taking place within an atmosphere of ecological sensitivity--appreciating the idea that the whole planet is a garden and all who live in it are gardeners.
One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.
