EARTH SANGHA | NATIVE ARBORETUM: REDISCOVERING OUR NATIVE FLORA
Our Native Arboretum project is transforming the Marie Butler Leven Preserve, a 20-acre park in McLean, Virginia, into an extensive collection of plants native to the greater Washington, DC, region.
Our objective is to create a botanical library. A broad range of native trees, shrubs, vines, and nonwoody plants will be available for viewing, accompanied by labels keyed to major field guides. The Native Arboretum will be a public resource for building ecological literacy, and for creating a stronger mandate for conservation.
The Native Arboretum project began in 2004. As you can see from the slide shows and other coverage available from this page, we have made very substantial progress. But the Preserve is heavily infested by invasive alien plants; we have had to fight the invasives for just about every square foot of area restored—and we still have an enormous amount of work to do. If you live in the DC area and would like to help, please consider volunteering!
