River otters are making a comeback in Sonoma County and across the Bay Area thanks in part to improved water quality and habitat restoration projects, according to ecologists.
In recognition of last week’s World Otter Day, local otter fans are hosting a Saturday lecture and series of kids’ activities at the Petaluma Regional Library from 11 a.m. to 1 p.m.
The message of the lecture will be one of resiliency and recovery, said Megan Isadore, executive director of the River Otter Ecology Project, which is hosting the North Bay event. A second event is also taking place in the South Bay.
Pollution of the San Francisco Bay and surrounding waterways decimated river otters during the middle of the last century, Isadore said, causing them to retreat to less polluted areas.
