2014 Informal Status Review for the Northern Distinct Population Segment of the North American Green Sturgeon (Acipenser medirostris)

Based on the last status review in 2005, NOAA Fisheries concluded that the Northern Distinct Population Segment (DPS) of green sturgeon did not warrant listing under the Endangered Species Act (ESA), but designated the species as a Species of Concern, due to concerns about fisheries harvest, alterations to freshwater habitat, and the lack of population data. This review summarizes our evaluation of and conclusions based on the new information that has become available since 2005 about the Northern DPS’ abundance, productivity, distribution, life history characteristics, and threats.
