Dunn’s Woods is an active site for research by faculty and students. Areas of study include methods of Purple Wintercreeper control and native species restoration, the influence of the soil microbial community on growth of exotic vs. native plant species, and plant species traits such as drought tolerance. Research to date shows that hand-pulling of Purple Wintercreeper is the most effective removal technique, native plants can be slow to recover and are vulnerable to herbivory by rabbits and other animals, soil underneath Purple Wintercreeper has a unique microbial composition and promotes its growth, and Purple Wintercreeper is more tolerant of drought stress than common native species.

Invasive Species Maps
Community partner Monroe County Identify and Reduce Invasive Species (MC-IRIS) led mapping of the most common invasive plant species in Dunn's Woods using geographic information system (GIS) technology. The resulting maps show that Purple Wintercreeper (Euonymus fortunei) had invaded over 50% of the woodland by 2010. Sixteen other invasive exotic plant species were also mapped, including Japanese Bush Honeysuckle (Lonicera macckii), Tree-of-Heaven (Ailanthus altissima), Common Buckthorn (Rhamnus cathartica), and Multiflora Rose (Rosa multiflora). The GIS maps provide a baseline to track progress and an invaluable resource for planning efficient invasive removal efforts.
