Wetland and Riparian Assessment on the Reservation

Wetland and Riparian Assessment on the Reservation
In September, the environmental department wrapped up its one-year assessment of the wetlands on the Chumash Reservation. Overall, the wetland areas and riparian corridor that run along Zanja de Cota Creek are in good ecological condition. Although invasive plant species are scattered throughout the creek, native vegetation communities are mostly intact and dominant. In fact, the native plant species diversity and coverage on the reservation was determined to be relatively high in relation to other similar riparian habitats in the Santa Ynez Valley. This riparian habitat provides important ecological functions such as habitat for native plants and wildlife, water quality filtration, flood control, and groundwater recharge. The table below outlines the vegetation communities that were identified on the reservation and mapped as part of the riparian assessment.
