Site description
a highly degraded wetland area with boardwalk access, overgrown with a non-native species (e.g., reed canarygrass and Himalayan blackberry).
Restoration challenge
Client wished to remove non-native vegetation and restore a native wetland plant community to promote habitat and provide educational opportunities for the public and nearby school.
Restoration approach
UW-REN students, working with community members and local school teachers and children, removed non-native species from around the boardwalk and on the slopes surrounding the central wetland. Mulch was added to reduce reinvasion. Native trees, shrubs, grasses, and herbs were added with a focus on species to (1) rapidly establish a shade canopy to control reinvasion by non-natives such as reed canarygrass, (2) promote succession to a mature evergreen forested wetland (inplanting on forested edge) and, (3) create structural diversity in the vegetation for habitat. Interpretive signage was added and long term stewardship and involvement by the grade school was fostered.
