September 2016 – MVSD is proud to announce our new partnership with the River Otter Ecology Project (ROEP) based in Marin County. Using a series of camera traps, we will try to figure out how river otters use the District’s wetlands and how many otters the wetlands support. Because of all of the spraints (otter scat) and other clues we frequently come across in the marsh system, we know we have a significant population of otters, but exactly how many and how they use and move through the wetlands is not currently understood.

We will be posting some of the videos we retrieve from the cameras and posting them here. As more video becomes available we will include new footage of otters and possibly other species including beaver, mink, coyote, fox, muskrat, raccoons, and others — so check back frequently! MVSD is grateful to Megan Isadore and Karen James for helping us to get this project off the ground.

More information about the River Otter can be found at the River Otter Ecology or their Facebook page.
