Jason Kreitler, Ph.D.
I am a research geographer for the Western Geographic Science Center (WGSC).
I work on the conservation of biodiversity and ecosystem services, and the enhancement of natural resource and wildland fire management activities within socio-ecological or human-environment systems. I conduct interdisciplinary studies to understand the consequences of climate and land use change to determine priorities for conservation action or to inform natural resource management. I employ geographic information systems, passive and active remote sensing, environmental modeling, and high performance computing in my quantitative analyses. My area of interest and expertise is the western USA.

Remote Sensing of Invasive Annual Grasses -- Greater Yellowstone Ecosystem
Exotic annual grasses such as cheatgrass ( Bromus tectorum ) have heavily invaded portions of the western United States, rapidly degrading habitats and increasing wildfire risk. Cheatgrass and other ESIs (desert alyssum [Alyssum desertorum], and annual wheatgrass [Eremopyrum triticeum]) are an emerging threat to the Greater Yellowstone Ecosystem (GYE); climatic changes including earlier snowmelt...
Integrated Wildland Fire Science
The size and number of large wildland fires in the western United States have grown dramatically over the past decade, with a contingent rise in damages and suppression costs. This trend will likely continue with further growth of the wildland urban interface (WUI) into fire prone ecosystems, hazardous fuel conditions from decades of fire suppression, and a potentially increasing effect from...
Land Use and Climate Change Team
We are a research team focusing on understanding the rates, causes, and consequences of land change across a range of geographic and temporal scales. Our emphasis is on developing alternative future projections and quantifying the impact on environmental systems, in particular, the role of land-use change on ecosystem carbon dynamics. We are interested in how land-use and climate systems will...
Changes to Watershed Vulnerability under Future Climates, Fire Regimes, and Population Pressures
The project aimed to use existing models and data to understand how wildfires (number, size, and location) and land-use change will affect watersheds, and therefore water supply, under current conditions and future climates (through 2050) in the western U.S. The projected changes in temperature and precipitation are expected to affect water supply in two major ways: 1) decreased water availability
