Final Recovery Plan for the Sei Whale (Balaenoptera borealis)
December 01, 2011
The 2011 Sei whale recovery plan which provides a research strategy to obtain data necessary to estimate population abundance, trends, and structure and identifies factors that may be limiting sei whale recovery
Sei whales are widely distributed in the world’s oceans. The sei whale has been listed as “endangered” under the Endangered Species Act since its passage in 1973. Because the current population status of sei whales is unknown, the primary purpose of this Recovery Plan is to provide a research strategy to obtain data necessary to estimate population abundance, trends, and structure and to identify factors that may be limiting sei whale recovery. These data will also provide greater understanding of natural and anthropogenic threats to the species.
