Identifying Sources Of Landscape Variation To Improve Predictions Of Post-Fire Sagebrush Steppe Recovery, Cara Applestein May 2023

Identifying Sources Of Landscape Variation To Improve Predictions Of Post-Fire Sagebrush Steppe Recovery, Cara Applestein

Boise State University Theses and Dissertations

Sagebrush steppe ecosystems are endangered landscapes, threated by the annual grass-fire cycle where invasion by annual grasses drives larger fires and larger fires drive invasion. Despite extensive input of resources by land management agencies, restoration of these ecosystems is notoriously variable and difficult to predict. Understanding and accounting for variation is key to effectively allocating limited resources and having success in restoring burned sagebrush landscapes. I utilized Bayesian modeling to assess how variation in weather, seed dispersal, and topography/slope/landscape position affects understanding of post-fire sagebrush-steppe recovery and how we can best incorporate sources of variation into models predicting where plant …
