- Closure of glades project
- As a follow-up the the species-richness study, investigated the utilization of old aerial photographs for delineating glades for future studies on closure of glades due to invasion of woody plants.
- Seed germination of cedar glade plants studies
- Preliminary manuscripts prepared and assessed for additional work on the following species: Forestiera ligustrina, Ligustrum sinense, Berchemia scandens.
- Enlisted a graduate student at the University of Kentucky (Lexington, KY) to conduct microscopy work on seeds of Berchemia scandens.

Impact of field ecology experiences on elementary student knowledge and attitude.
Field ecology experiences with elementary students can improve student knowledge about that particular system; however field experiences offer challenges that may impact attitude not associated with the classroom such as heat, insects, and lack or other amenities. Student collected data in this study was an accurate representation of existing literature on glade plant distribution.
Determinants of species richness on glades
Species richness on glades follows typical island biogeography theory. However, the invasion of exotic species does not support the diversity-resistance hypothesis. Thus, (1) glades of all sizes are important in conservation efforts particularly for acting as corridors and (2) exotic species invasion on glades is unique probably since community structure in glades is governed more by stress than competition.
First of its kind, a 1-day workshop was held to allow interaction among key stake-holders for cedar glades and facilitate focus on research needs of cedar glades.
