Online Map of Volunteer Projects
Are you working on a volunteer project to address invasive plants? Volunteer groups have begun adding their invasive plant management projects to an online map, with brief descriptions of the project. This allows volunteers to see what efforts are going on near them and who else is working on particular plants of concern.
Instructions for adding your projects to the Wildland Volunteer Map!
