Characterized by their extreme size, intensity, and severity, megafires are the most destructive, dangerous, and costly wildfires in the U.S. Over the past two decades, megafires have become more frequent in Oklahoma and Texas along with increasing extreme weather events and changes to fuel types caused by woody plant encroachment into grasslands. As climate change and woody plant encroachment are expected to continue or even accelerate, it is important to evaluate megafire risks and locate high-risk areas. This project will develop a new Megafire Risk Evaluation System (MERES) and make future projections of megafire probability in Oklahoma and Texas from 2024 to 2100. Outcomes and products from this project will...

As effects of climate change intensify, there is a growing need to understand the thermal properties of landscapes and their influence on wildlife. A key thermal property of landscapes is vegetation structure and composition. Management approaches can alter vegetation and consequently the thermal landscape, potentially resulting in underappreciated consequences for wildlife thermoregulation. Consideration of spatial scale can clarify how management overlaid onto existing vegetation patterns affects thermal properties of landscapes relevant to wildlife. We examined effects of temperature, fire management, and vegetation structure on multi-scale habitat selection of an ectothermic vertebrate (the turtle Terrapene...

Fire is a natural and necessary component of the South Central Plains ecosystem. However, fire suppression and more frequent droughts in the region have resulted in a build-up of dry fuels loads such as dead wood, resulting in fires that burn hotter and impact the landscape more severely. Uncontrolled wildfires have cost the region several billion dollars in the past five years. Further, fire suppression has resulted in substantial losses in native plant biodiversity and wildlife habitat, which also has costly implications. In Oklahoma alone, it’s estimated that $157 million will be required to restore rangelands to their native conditions. Of further concern is the fact that projected changes in climate indicate...
