My research (carried out in collaboration with Drs. Jeremie Fant, Kayri Havens, Krissa Skogen and Dan Larkin) as part of our Conservation And Restoration in Changing Environments project uses the tools of ecological genetics to answer questions aimed at making ecological restoration practices as economically feasible and successful as possible. Most of this work takes place in the western United States, where there is a great need for restoration on a large-scale. Restoration efforts are often hampered by a lack of information about which species and seed sources should be used to maximize restoration success. Even when this information is known, the availability of seeds often limits what can be done for the restoration. I use ecological genetics research to inform the selection of species and seed sources for restoration, and to support the development of native plant material that will allow species diversity and ecosystem function to be restored to degraded arid environments in the western U.S.
I am also working with collaborators here at Chicago Botanic Garden, the University of Wyoming, and Middle Tennessee State University on a project that, if funded, will quantify the genetic and environmental controls on critical stages of plant recruitment success (seed dormancy, germination and establishment) for an array of native species spanning the central United States. Results of this research will help us understand the ability of plant species to respond to changing climates.

Conservation and Restoration in Changing Environments (CARICE)
Much of the native habitat in the western United States is degraded as a result of changes imposed by invasive species, altered fire regimes and land use patterns, and a shifting climate. These changes will only become more prevalent in the future. To ensure the region's unique plant and animal diversity, and the ecosystem services it provides, is resilient in the face of these changes, restoration on a large-scale is needed. To help make restoration efforts as efficient and effective as possible, we conduct applied research to inform restoration in the arid environments of the western U.S. (particularly the Colorado Plateau and Great Basin).We focus on two broad research themes: 1) Identifying, developing, and using appropriate native plant material for successful restoration; AND 2) Quantifying and restoring ecosystem function that has been lost
Botanic Gardens Conservation International
Botanic Gardens Conservation International maintains information on plant conservation and education around the world, highlighting the important work of botanic gardens and partners in achieving the Global Strategy for Plant Conservation. From 2008 - 2013 I was Executive Director of BGCI in the United States and helped develop numerous projects in support of the Global Strategy for Plant Conservation, including ex situ conservation of exceptional species, botanical capacity in the United States, a North American assessment of ex situ collections, and developing conservation interpretation materials for public gardens.
Seeds of Success
The national Seeds of Success program, established in 2001 by the Bureau of Land Management and the Royal Botanic Gardens Kew Millennium Seed Bank, is working to collect, conserve, and develop native plant materials for stabilizing, rehabilitating and restoring lands in the United States. Many botanic gardens, including the Chicago Botanic Garden, are partners on this nationwide project. I learned a lot about the power of partnership from this program, and am proud that my research helps inform its work.
Center for Plant Conservation's National Collection of Endangered Plants
As an endangered plant specialist, I managed a two-year, collaborative project (funded by the Institute of Museum and Library Services, or IMLS) to create CPC's National Collection of Endangered Plants website. This site outlines what the network of CPC-member botanic gardens are doing to help conserve more than 575 threatened and endangered plants in the United States, and details each species' current status, as well as management and research needs. This project was completed in December 2002, and the site is now hosted and continually updated on the Center for Plant Conservation's website. This project allowed me to interact with the wonderful network of researchers at botanic gardens around the country who are working to conserve the nation's imperiled plants, and also showed me the significant need for more research to help guide management decisions for these rarest of plants. This experience strongly influenced my decision to pursue my Ph.D. and conduct research with real on-the-ground applications.
Plants of Concern
As a Garden intern, I worked with Garden scientists on research aimed at understanding the population biology of threatened/endangered plant species in the Midwest (including Viola conspersa, Platanthera leucophaea, and Lespedeza leptostachya). This research helped form the basis for long-term monitoring protocols on rare species in the Chicago region, in what is now the Garden's Plants of Concern program.
