Invasive plants of southeastern US forests

Key Personnel
   Gary Ervin, lead PI
   Adrian Lazaro-Lobo, doctoral student
   David Mason (former Master's student)
   Rima Lucardi, Ph.D., former doctoral student, current collaborator with the US Forest Service
   Anna Greis, current collaborator with the US Forest Service

We have been involved in several projects investigating invasive plants of southeastern US forests.  As you'll notice below, most of what we've published in this area has dealt with cogongrass, (Imperata cylindrica).  Currently, both David Mason and Adrian Lazaro Lobo are working in this general area, with work by each student just getting underway, as of summer 2017.

We also were heavily involved with an online outreach project, the Invasive Plant Atlas of the Mid-South, that provides distribution maps of many invasive plants of the region, as well as fact sheets on some of the more problematic species.  Most of the distribution data from this project also are available via EDDMapS (Early Detection & Distribution Mapping System).
