    Applying Nature's Design
    Book Description:

    The fragmenting of habitats is endangering animal populations and degrading or destroying many plant populations throughout the world. To address this problem, conservationists have increasingly turned to biological corridors, areas of land set aside to facilitate the movement of species and ecological processes. However, while hundreds of corridor initiatives are under way worldwide, there is little practical information to guide their design, location, and management. "Applying Nature's Design" offers a comprehensive overview of current knowledge on corridors, their design, and their implementation. Anthony B. Anderson and Clinton N. Jenkins examine a variety of conceptual and practical issues associated with corridors and provide detailed case studies from around the world. Their work considers how to manage and govern corridors, how to build support among various interest groups for corridors, and the obstacles to implementation. In addition to assessing various environmental and ecological challenges, the authors are the first to consider the importance of socioeconomic and political issues in creating and maintaining corridors.

  5. 1 Introduction
    (pp. 1-10)

    Today’s biodiversity crisis is the direct result of the conversion and loss of natural habitat occurring worldwide at unprecedented rates and scales. Between 1945 and 1990, about 20 million square kilometers — or nearly 17 percent of the Earth’s vegetated area — became degraded (WRI 1992: 112). Logging and conversion have shrunk global forest cover by at least 20 percent, and some forest ecosystems — such as the dry tropical forests — are virtually gone (UNDP/UNEP/World Bank/WRI 2000). Over half of the world’s coral reefs are under serious stress resulting from destructive fishing practices, pollution, and global warming (Hughes et...

  6. 2 Conceptual Foundations of Corridors
    (pp. 11-26)

    This chapter reviews the foundations of the corridor concept, examines the wide array of terms associated with corridors and suggests their division into two basic types, and then assesses the scientific debate regarding corridor functions, benefits, and costs.

    The concept of corridor implementation as a conservation strategy derives from the assumption that maintaining or restoring connectivity at diverse scales is essential for conserving biodiversity in increasingly fragmented natural ecosystems and communities. The significance of connectivity for conservation rests on three conceptual frameworks: the equilibrium theory of island biogeography, the dynamics of populations separated into habitat patches (“metapopulations”), and principles of...

  7. 3 Corridor Design
    (pp. 27-50)

    There is no magic formula for designing biological corridors. Corridor design is highly specific to the unique requirements of the species, habitats, ecosystems, and ecological processes of concern (Friend 1991, Debinski and Holt 2000). Furthermore, design must account for not only the biophysical elements of a corridor but the socioeconomic and political factors influencing corridor configuration and implementation (e.g., Newmark 1993, Kaiser 2001). An understanding of corridor design can be obtained by reviewing how scientists and practitioners are approaching the problem, and by identifying guiding principles and recommending practical steps for the design process.

    When considering approaches to corridor design,...

  8. 4 Corridor Implementation
    (pp. 51-80)

    This chapter examines five key questions related to corridor implementation. The answers to these questions are likely to determine whether corridor implementation can begin in the first place, and whether it will be sustainable over the following years and decades. Following this discussion, the chapter concludes with an analysis of how issues such as incentives, resource management, and governance need to be addressed together as part of a corridor implementation strategy.

    The questions are:

    How do you manage corridors?

    What are the obstacles to implementing corridors?

    How do you build support for corridors?

    What are effective incentives for corridors?


  9. 5 Case Studies
    (pp. 81-196)

    Upon embarking on the search for corridor cases for this book, we expected that it would be possible to select only corridors under full implementation. Yet despite the existence of probably hundreds of corridor initiatives worldwide,¹ and after examining dozens of cases, we found that almost all are in the planning stage, extremely few are under implementation, and none has been under way for a sufficient time to allow a full evaluation of its results. This discovery led to a revision of the criteria for selecting potential case studies for this book. While implementation was still a factor in selection,...
