One of Central California’s most ancient fish, the green sturgeon, now has a plan that will steer it toward recovery. NOAA Fisheries released a final recovery plan under the Endangered Species Act (ESA) on August 21, 2018. The plan is non-regulatory and identifies steps that will guide state and federal actions to promote recovery of the green sturgeon’s threatened southern population.
Federal Protection
NOAA Fisheries biologists divided the green sturgeon into two distinct populations segments based on what we know about the species. In 2006, the southern population – covering Central California – was listed as threatened under the ESA. The northern population was more abundant so ESA-listing was not warranted at the time.
As part of the ESA protection for the southern population, NOAA Fisheries has been working with the states of California, Oregon, and Washington, other federal agencies, and non-governmental organizations to identify actions that will aid in the recovery of the southern population of green sturgeon.
Plan for Recovery
The recovery plan identifies a number of research, monitoring, and outreach actions for the southern population aimed at restoring fish passage and habitat, reducing sources of mortality, and addressing known threats including climate change, predation, and contaminants. Most recovery efforts focus on threats to freshwater and estuarine spawning and rearing habitats — the areas that are considered the greatest impediments to recovering the species.
“The recovery plan is a key step in promoting public awareness of green sturgeon and encouraging participation in restoring the southern population,” says Joe Heublein, a NOAA Fisheries biologist who coordinates the multi-agency recovery effort. Read more
