Description

As we strive to manage the Columbia River Basin for its sustainable, productive, and diverse ecosystems, we are, in fact, managing these systems to provide an a array of ecological functions upon which these systems are based. These ecological functions avail themselves as an important tool with which to assess our historical and current habitat conditions, as well as proposed future or ideal conditions under differing management scenarios. So what are key ecological functions (KEFs) and which ones are involved? Key ecological functions refer to the major ecological roles played by an organism in its ecosystem that can affect environmental ... continued below

Description

As we strive to manage the Columbia River Basin for its sustainable, productive, and diverse ecosystems, we are, in fact, managing these systems to provide an a array of ecological functions upon which these systems are based. These ecological functions avail themselves as an important tool with which to assess our historical and current habitat conditions, as well as proposed future or ideal conditions under differing management scenarios. So what are key ecological functions (KEFs) and which ones are involved? Key ecological functions refer to the major ecological roles played by an organism in its ecosystem that can affect environmental conditions for themselves or other species, or that directly influences other organisms (Marcot and Vander Heyden 2001). Currently, 111 KEFs are identified for fish and wildlife species as a result of Task 1 of this project. Even though the assessment phase of this project encompasses the entire Columbia River Basin, only a subset of KEFs (58) that are associated with the lotic systems, which includes 7 anadromous fish, 20 co-occurring resident fish, and 137 wildlife species linked to salmon are addressed. Since the basin has not be systematically surveyed for each fish and wildlife species, baseline conditions for each KEF are determined by developing basin-wide species range maps using the following information: wildlife-habitat type associations, county and ecoprovince occurrence, literature (like individual state atlases), and expert peer review. This approach produced a set of species range maps that depict a species potential for occurrence given the current or historic conditions. It is this potential occurrence that serves as a baseline condition to determine the key ecological functions. The results offer a framework and a set of baseline assessments that can be done with existing databases. Thus, allowing resource managers the ability to assess future management activities against this norm and guide their activities in prioritizing inventory, monitoring, and mitigation efforts with ecosystem-based management. This project uses the species distributions in conjunction with a set of wildlife-habitat relationship matrices to construct and assess a functional analysis for each of the 62 subbasins. The analysis compares functional changes from historic to current conditions across the Columbia River Basin and address community functional patterns, geographic functional patterns, and species functional roles. Products from this work include: (1) current distribution maps for fish and wildlife species (including winter range maps for birds); (2) historic distribution maps for native fish and wildlife species; (3) list of KEFs for each anadromous, resident fish, and wildlife species (species functional profiles); (4) KEF assessment of community and geographic functional patterns for each of the 62 subbasins in the Columbia River Basin; and (5) a set of functional profiles based on the species and wildlife-habitat occurrence within each subbasin.
