Chapter 8: Countering fragmentation of habitats under international wildlife regimes
The focus of this chapter is on the threat of habitat fragmentation, and the corresponding challenge of connectivity conservation. In particular, the chapter aims to identify the varying extents to which international wildlife regimes are conducive to, or even require, the maintenance or achievement of an adequate degree of ecological connectivity. The latter can be achieved, for instance, by maintaining or (re-)establishing corridors between protected areas, by equipping highways and other human infrastructure with wildlife overpasses, and other measures countering the fragmentation of habitats. Ensuring adequate connectivity was always an important element of wildlife conservation. Climate change is now adding to the challenge, as connectivity conservation is a central component of strategies to facilitate the adaptation of wild flora and fauna to climate change. The structure of the chapter is as follows. The next section contains a concise introduction to fragmentation as a biodiversity conservation problem, and of the associated need for connectivity conservation (Section 2). The subsequent sections are then composed of analyses reviewing relevant international legal wildlife regimes from a connectivity conservation perspective.
