How many fish bones did the archeologists find? The information is used to inform agencies like the CDFW, OSPR, restoration managers, wildlife rehabilitation groups and state, national and local parks.

And were rewarded with are very first tail slap. They seek a source of fresh water, to drink and help groom their thick fur, and good supplies of prey. At such high levels, some of these contaminants can have negative impacts on otter ranging from poor survivorship to sterility or infertility.

Isadore sees otters as a way in to understanding relationships between other things—how otter prey like the endangered coho rise and fall, whether local improvements in water quality outweigh the new pressures of climate change for otters.

Life history studies have shown that otter are dependent upon permanent watersheds, and otter may be found in rivers, lakes ponds, small streams, marshes and other inland wetlands. I came across this lovely one that seemed to be missing someone important.

River Otter

Like all true members of the weasel family, they travel overland in a loping or bounding manner, and prints may vary considerably with terrain, ground surface and stride.

They will move along the ground or down a slope on their belly. Otter do maintain home ranges, but little in the way of documented territorial disputes exists, as family groups have been noted to avoid one another.

Externally, ticks, fleas, and lice can be found. Reproduction Adult river otters breed with more than one mate in their lifetime, and the breeding season may span from December to May, depending on geographic location.

As ofROEP has catalogued more than 1, sightings and added to that tally close to 5, camera-trap videos and photos and roughly 1, samples of otter scat.

Young adult males leave after a year and strike out on their own to find and establish their own territory. I personally am thrilled that otters can serve as the ambassadors to our creeks systems and get folks thinking of water health.


Each female gives birth to between one and four pups and then, shortly after, will breed with a male in preparation for the following winter. Males and females are reproductively mature in their second year, but occasionally one-year-olds have been found to have given birth.

Throughout most of their range, there is a close relationship between beaver and river otter populations, indicated by a positive relationship between annual trapper harvests of the two species. Today, scientists confirm that otters occupy much of their former Bay Area territory. We are having quite an adventure in beaver-less Mendocino.


Otters were trapped for two reasons: This accumulating effect results in elevated levels of pollutants in river otter due to the ingestion of contaminated food items.The River Otter Ecology Project is a citizen science project to Fill key gaps in biology/ecology of River Otters in San Fran Bay.

The River Otter Ecology Project is a registered (c)(3) EIN # non-profit organization dedicated to the welfare of river otters and our watershed. We receive no government funding, and depend solely on financial support from our friends. This alert has been closed and is no longer available. River Otters Are Back!

Presentation with Megan Isadore, Executive Director of the River Otter Ecology Project. The River Otter Ecology Project works to build understanding and shed light on the conservation status and ecology of the North American river otter and the ecosystems they inhabit in the San Industry: Environmental Services.

We are gratefully adopting the protocol of the River Otter Ecology Project.
