My research empahsizes the temporal-spatial dynamics of rangeland ecosystems throughout western North America. I utilize remote sensing, GIS, and GPS technologies to address ecological questions. Areas of focus include 1) predicting optimal sage-grouse nesting and brood-rearing habitat at multiple spatial scales, 2) characterizing the effects of fragmentation and connectivity on wildlife habitat use, 3) assessing landscape-level affects on juniper woodland succession on ecosystem structure and process, and 3) monitoring wild horse disribution patterns and vegetation utilization. I am currently working with three graduate students; Matt Madsen (Ph.D.) - Effects of post-fire hydrophobicity on juniper hydrology; Bracken Davis (M.S.) - Predicting the probablity of occurance for several native forb species throughout Utah; Chris Balzotti (M.S.) - Predicting species distribution patterns detected from remote sensed imagery in Tropcial Forests of Guatemala. |
