The plants listed below are an ongoing effort to document the many species that occur within the Environmental Studies Center. Data collection has taken place over the last ten years, and has been a collaborative effort involving faculty, students, volunteers and the Metro Greenspaces Program. Clicking on some plant names (as well as numbers listed after species name) will lead to photos that have been taken on campus.
