Restoring Native Habitats in Urban Landscapes

Kara Smit

In this project, the student will work in Calvin鈥檚 greenhouses, tree nursery, and at sites on and off campus investigating the re-introduction of native plants and native habitats into urban areas. Part of this work will involve collecting and processing data from an experimental prairie planting near the Prince Conference Center, assessing the best soil conditions for establishing native prairie plants. The student will also work with Dr. Warners in designing and installing an expansion of this experimental restoration planting. This student will also assist with restoration projects done off campus by Plaster Creek Stewards, with particular focus on developing sampling protocol to monitor the success of these projects over time.
