In 2009, Stewards began a partnership with Sonoma Water to monitor pinnipeds at or near the Russian River mouth in response to the need for a federal permit for incidental harassment of marine mammals during the activities associated with the requirements of the biological opinion.
The biological opinion (BO) is a 15-year recovery plan to implement the mandates of the National Marine Fisheries Service (NMFS) as they relate to threatened and endangered fish in the Russian River and its tributaries. More information is available on the Sonoma Water website.
Trained citizen monitors are counting seals at numerous locations in and around the Jenner Estuary during breaching activities and during the outlet channel formation that is recommended in the BO. Monthly baseline data collection is also scheduled twice a month.
Tasks: Pinniped monitors collect monitoring equipment at the Jenner Visitor center before their shift begins. With the equipment, they drive to the Jenner overlook and use the data sheets to record information such as weather, wind speed, number of individuals observed, and location of seals. Monitors return the equipment and completed data sheet to the Jenner Visitor Center after completing their shift.
Meeting times: Shifts are 4 hours scheduled twice per month, every month. Surveys are conducted Monday thru Friday with shift times starting at 11:30am.
Training and requirements: No prior experience is necessary! New volunteers should attend and register for a Pinniped Monitoring training. Volunteers will then shadow experienced volunteers until they feel comfortable on their own. New volunteers are required to attend one General Orientation, and encouraged to attend our affordable seminars to further their education.
Feel free to watch this recorded training from June 23, 2020
