The River Otter Ecology Project (ROEP) Produces Second Report for MVSD

MVSD and ROEP began a partnership in September 2016 to better understand the population of North American River Otters in the Peyton Slough Wetlands. This second report from ROEP highlights what was learned in the first 10 months of the study including otter presence, abundance and habitat use within Moorhen and McNabney marshes, sex ratios, and recommendations for mitigating disturbance to otter populations for tide gate closures and the Moorhen Marsh Western Pond Turtle Habitat Enhancement Project in 2017 and 2018.

We are also pleased to announce that we will be adding a prey study later this year to better understand otter diet and foraging ecology in the wetlands. To access the latest report, please click on the link below.
