Title: Joining laboratory, greenhouse, and field approaches to improve our understanding of fire effects on seed germination in Great Basin, Colorado Plateau, and Sonoran deserts.

Project Proposal Abstract: Fire has strong control over our western landscapes, and the patterns and intensities of fire have changed through time. What hasnt changed is that, from a management perspective, we have always wanted to maintain certain key functions and to facilitate the recovery of desirable vegetation. Existing seed banks provide an important component of regeneration, because they are locally adapted seeds that have strong potential to help plant communities recover quickly following fire. However, more information is needed  particularly in the context of how heat from fire affects the potential for certain species to germinate  before we could revise our understanding of seed bank seeds capacity to become a more powerful component of post-fire restoration. This proposed research aims to: (1) improve our understanding of how germination in different but common native and exotic plant species respond to the high temperatures associated with fire, (2) assess if soils that have been previously burned have properties or seed banks that are more or less resilient to heat, (3) assess how other soil characteristics, such as soil moisture and biological soil crusts, interact with high temperatures to affect seed viability, and (4) to communicate the results to a wide range of resource managers and decision makers.
