Deserts are literally the coolest places on earth! My current research interests involve desert community ecology focusing on how disturbance, such as wildfire and grazing, affect the plant community. Recent research projects include using drones to quantify effects of invasion of exotic grasses in rare endemic plant habitat in the Mojave desert, how extreme drought and different grazing strategies will alter desert perennial grasslands on the Colorado Plateau. and how changes in preciptation timing and wildfire affect plant competition and invasion patterns by modifying community trophic interactions. I am also interested in using GIS platforms and remote sensing to track and map invasive grass species across the major deserts of the Western United States, and using hyperspectral imagery to link plant species to distribution and ecosystem change. Another cool project I am working on is using historical repeat photography to be able to quantify plant community change in the Colorado Plateau national parks from early 1900's. These photos can publicly be found on the NPS website.
Why This Research is Important“We didn’t start the fire” may be Billy Joel’s way of passing the buck on the world’s problems but unfortunately, it doesn’t quite apply now. It turns out, we are starting the fires. Fire regimes are changing worldwide and in the United States, humans have tripled the length of the fire season along with hotter and drier conditions linked to human accelerated climate change. Increased human ignitions of wildfire is of particular concern because of another major ecological issue: invasion of exotic grasses.
Mechanisms of successful exotic grass invasions are critical in understanding how, where, and why invasion may happen and what can be done about it. Invasion of exotic grasses increase they frequency and severity of wildfire in the US by providing ample fine fuel in otherwise fuel limited communities. Likelihood of wildfire increases 2-4 times when exotic grasses are present. However, less is known for how these invasions establish to the level of causing catastrophic fire. Life history traits such as phenology differences, prolific seed production, and typically “fast” growth as compared to natives are all linked to exotic invasion success. My research focused on elucidating mechanisms driving exotic grass invasion success in the context of wildfire, such as precipitation timing, top-down control from herbivores, and competitive interactions.
As wildfire is increasing across the globe, this research provides timely and critical evidence of community level mechanisms of successful plant invasions. This will continue to be necessary if we are to be successful in mitigating the life-threatening detriments of climate change and wildfire.
