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 change, the factors that influence restoration effectiveness, and the ability of restored sites to perform key functions and services such as biodiversity support and nutrient cycling.

Ongoing research projects include:

  • Understanding the influence of phylogenetic diversity on prairie restoration outcomes (with collaborators at the Garden and The Morton Arboretum)
  • Ecology, genetics, and management of the invasive wetland grass Phragmites australis (with Jeremie Fant, Eric Lonsdorf, Vicky Hunt, and others)
  • Effects of vegetation change and restoration on wetland denitrification (with Paul Hartzog)
  • Responses of native-bee communities to grassland restoration (with Becky Tonietto)
