Activities:
Ecological research that aims to bring about better conservation, restoration, management, monitoring, and understanding of natural areas and their floras/faunas-- mainly in human dominated landscapes.
Research:
Applied ecology in the Midwestern U.S., mainly related to:
---Conservation of Biodiversity;
---Non-native plant invasions;
---Restoration Ecology;
---Natural areas management;
---Urban Ecology;
---Fire Ecology;
---Human disturbance in natural areas;
---Floristic Quality Assessment;
---Oak-hickory forest regeneration;
---Vegetation monitoring
