Species Data Gaps – State Wildlife Action Plan

SPECIES OF GREATEST INFORMATION NEED

Oregon’s State Wildlife Action Plan (SWAP) identifies 176 Species of Greatest Information Need (SGIN), including 8 amphibians, 23 birds, 11 mammals, 2 reptiles, 34 fish, 7 plants, 3 algae, and 88 invertebrates. The SWAP SGIN list documents species that require more information to determine whether they should be elevated to Species of Greatest Conservation Need (SGCN) status.

SGIN are species potentially vulnerable or of concern, but for which current data and understanding are scarce. For these species, some basic information, such as habitat associations and general abundance, is not known. It is, therefore, not possible to determine whether they are truly at risk and should be designated as a SGCN. General areas in which SGIN are lacking basic information include taxonomy, distribution and range, population dynamics or trends, threats or stressors, and habitat requirements. For SGIN, conservation actions should be aimed at filling these data gaps.

The SGCN and SGIN lists are available for download in Excel table format.
