The West Multnomah Soil & Water Conservation District is working with Lewis & Clark College to create a conservation plan for about 59 acres owned and managed by the private college in Southwest Portland.
The conservation plan calls for controlling invasive plants, installing native plants and making the land more manageable for private landowners.
Lewis & Clarks property is located next to the 146-acre River View Natural Area recently purchased by the city of Portland from River View Cemetery, as well as the Tryon Creek State Natural Area.
The first phase of the conservation plan calls for crews to cut ivy and clematis from mature trees, a process known as air gapping, on 26 acres next to the campus, north of Southwest North Drive.
The second phase of the plan would improve 20 acres adjacent to Tryon Creek, including headwater tributaries.
The third phase covers the natural area around the Lewis & Clark graduate campus.
The soil and water district project hopes to engage Lewis & Clark students, faculty and staff, as well as community supporters working through SOLVE.
The soil and water district also has been working since 2011 on a conservation plan to improve native forest and other lands owned by River View Cemetery. Invasive plants were growing in some cases up to the crowns of the trees there. In February, more than 2,000 native plants will be installed there, among other ongoing work.
