Plant Science & Conservation
I’m a conservation scientist here at the Chicago Botanic Garden. I have an incredible job that allows me to work with many wonderful graduate students and a team of researchers to study ways to restore natural areas in the Colorado Plateau.
If you’ve ever visited national parks like the Grand Canyon or Arches, you’ve experienced at least some of what the Colorado Plateau (also known as the Four Corners region) has to offer. It includes more than 80 million acres across Utah, Colorado, New Mexico, and Arizona—and the largest concentration of national parks in the country.
Our research team heads out across a recently-burned area in search of data.
Although beautiful, the Colorado Plateau’s natural areas are facing many threats, including wildfires, a changing climate, and destructive invasive species such as cheatgrass (Bromus tectorum) and Russian knapweed (Acroptilon repens). Working with many partners, including the Bureau of Land Management, we are studying which native plants may be best able to handle these growing threats (we refer to them as “native winners”). The ultimate goal is to help make restoration of these plants and habitats as effective as possible in order to maintain healthy natural areas that support wildlife and pollinators, and help keep our air and water clean.
This is no small task. The invasive species that the native plants are up against are very impressive. For example, Russian knapweed is allelopathic (prevents other plants from growing nearby), and it has roots that can grow more than 20 feet deep, seeking the water table. Fortunately, some native species are also able to grow in these conditions, and some even appear to be evolving and adapting to be better competitors.
Three Northwestern University graduate students are working with me. Master’s student Nora Talkington is testing how different populations of a native grass are able to compete with Russian knapweed, while doctoral student Alicia Foxx is researching how different root structures of native plants help them compete with invasive species. Master’s student Maggie Eshleman is studying six native wildflower species including the smallflower globe mallow (Sphaeralcea parvifolia), which has tiny, fiery orange flowers. These wildflowers are likely “native winners” and are strong candidates for increased use when restoring habitat in the Colorado Plateau.

How cool is it to be able to take research that’s been done on a small scale and actually apply it to the real world? I feel so lucky to be able to do this work, and being here at the Chicago Botanic Garden has allowed me to build long-term partnerships that investigate the application of research, rather than just focusing on publishing it. Stay tuned for updates on how these native winners perform.
