Statement

Ecological restoration, "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed" (Society for Ecological Restoration International), is a vital conservation strategy that is difficult to do well. I am interested in what factors constrain the recovery of degraded habitats, and the extent to which different restoration approaches can overcome those constraints.

For example, invasive plant species can profoundly alter the habitats they invade, decreasing local diversity of plants and animals and changing aspects of the physical and chemical environment, nutrient cycling, and other processes. Restoration is not just a matter of removing the invasive species itself, but of dealing with the legacy invasion leaves behind.

My students and I conduct research to better understand the process of ecological recovery, the factors that limit restoration effectiveness, and the ability of restored sites to perform key functions and services such as biodiversity support, carbon storage, and nutrient cycling.

Ongoing projects include the following:

  • Effects of Rhamnus cathartica (buckthorn) invasion and woodland restoration on carbon-storage ecosystem services (with Jim Steffen)
  • Effects of prairie restoration on native bee communities (Ph.D. student Becky Tonietto)
  • Control of Lythrum salicaria (purple loosestrife) (with Joan O'Shaughnessy and M.S. student Jennifer Alyah)
  • Measuring restoration effectiveness in the Colorado Plateau (with Jeremie Fant, Krissa Skogen, and Emily Yates)
  • Genetics and ecology of Phragmites australis (common reed) invasion (with Jeremie Fant and M.S. student Amy Price)
  • Nutrient cycling in restored wetlands (Ph.D. student Paul Hartzog)
  • Effects of plant-community structure and restoration on use of wetlands by secretive marsh birds
