However, because each of these three ecoregional classifications rest primarily on terrestrial classification criteria, they are not usually spatially suitable for regional freshwater biodiversity planning. This is due to the fact that freshwater biodiversity patterns and the source areas for threats to these patterns often correspond to drainage basins, whereas the borders of terrestrially-defined ecoregions often cut across basin boundaries. Freshwater planning conducted solely in the context of terrestrially defined boundaries may result in inaccurate priorities and inefficient conservation strategies that fail to consider ecological patterns, connectivity, and hydrologic issues adequately to maintain freshwater ecosystems.

Finally, geology determines the amount and distribution of relief, or variation in elevation, present across a watershed. Relief shapes several features of freshwater ecosystems. For example, the overall slope of the watershed determines how rapidly water runs off into its water bodies, and the gradient of a river determines how fast the river will flow and the size of a river’s bottom substrate material.

This chapter examines this dilemma and presents three questions that, when answered, can help practitioners determine how to focus their conservation efforts (adapted from Redford et al. 2003): • What biodiversity should be conserved? • Where should the biodiversity be conserved? • How can the biodiversity be most effectively conserved? This chapter also describes regional and local scale approaches for focusing freshwater biodiversity conservation efforts. 37 38 A PRACTITIONER’S GUIDE TO FRESHWATER BIODIVERSITY CONSERVATION WHAT BIODIVERSITY SHOULD BE CONSERVED AND WHERE SHOULD IT BE CONSERVED?
