Area of Expertise:Riparian Ecology
My research is focused on the biology of the Northern tamarisk beetle (Diorhabda carinulata) and its colonization of Western Riparian zones, largely in relation to the issue of tamarisk management and riparian restoration. This interest roughly began in 2005 during my undergraduate Senior Thesis, in which I looked at the dissimilar seedling abundances of cottonwoods (Populus deltoides) and invasive tamarisk (Tamarix ramosissima) along the Dolores River, in Colorado.
Area of Expertise:Wildfire, restoration, land-use change, conservation biology
My interests are in fire ecology and its role with change in ecosystems. I am specifically interested in large scale landscape fire projects and the role of policy and environmental change associated with these types of projects.
Before coming to the University of Arizona, I was an Environment Peace Corps Volunteer in the Dominican Republic. There I worked in a rural area on water quality and sanitation projects with a fisherman’s group and with a women’s group on a small business development project.
Area of Expertise:I’m interested in improving rain harvest for arid areas through experimental rain basins at Biosphere 2. Eventually, I will communicate my results to a wider professional and public audience to guide any large-scale implementation.
Area of Expertise:environmental management
Area of Expertise:Use of thatch to reduce buffelgrass seedling emergence
Invasive buffelgrass (Pennisetum ciliare) is a major threat to the Sonoran Desert ecosystem. Manual removal continues to be an important method of buffelgrass control in southern Arizona. A problem of traditional manual removal practices is that they create areas of bare, disturbed soil that are often very favorable for buffelgrass seedling emergence. I am testing the use of thatch comprised of uprooted buffelgrass plants as a means of limiting seedling emergence in treated areas. I am investigating whether light attenuation resulting from thatch is a major fact
Area of Expertise:invasive plant ecology and management, vegetation monitoring, restoration/revegetation of severely disturbed arid ecosystems, coordination of regional vegetation management efforts
Starting in 1999, I began working with the Natural Resources Conservation Service Plant Materials Center in Tucson. I assisted with the production and maintenance of field and greenhouse plantings, made seed and propagule collections from the field, and assisted with the installation of experimental in situ plantings and the evaluation of research results. I became familiar with concepts of plant breeding systems, problems with selection on growing wildland plants in crop settings, and the selection of propagule source populations for maintenance of genetic diversity in new

On August 30th, the School of Natural Resources and the Environment welcomed all graduate students to attend the SNRE Back-to-School Reception with faculty.
Each Professor prepared a slide to introduce themselves and discuss their research. For those that were not able to attend, the slides can be found here: New Student Orientation - About Our Faculty.
SNRE Seminar: Advancing the Field of Landscape-scale Approaches to Conservation, Resource Management, and Sustainability
08/26/2011 - 1:00pm
Location:Bio Sciences East Rm 225
Speaker: Shawn Johnson, Center for Natural Resources and Environmental Policy, University of Montana
University of Arizona scientists and extension personnel will be featured speakers in a 2-day workshop on climate and forests. Lead conference organizer Chris Jones, UA Gila County cooperative extension agent, and colleagues from the UA School of Natural Resources and the Environment and the School of Earth and Environmental Sciences worked with colleagues from the USDA National Institute of Food and Agriculture and other universities and agencies to bring together natural resource extension agents, forest ecosystem scientists, and others from around the U.S.
