All The National Park Service is looking for invasive plant interns in DC. NPS is conducting invasive plant control work in the Potomac Gorge; an area that contains globally-rare plant communities, stunning vistas, and minutes from the nation's capital.
If you are interested please apply through the Student Conservation Association: http://www.thesca.org/serve/position/rare-plant-and-vegetation-management-interns/po-00683722 The project will take place between Spring and Fall semesters so it is a great opportunity for current students.
