Sagebrush occupancy resulting from aerial seeding five years post-fire

Evaluating factors that affect recovery of canopy-forming, foundational species is needed to guide effective treatment implementation aimed at mitigating their loss due to the changing fire regimes being experienced in semi-arid shrub-steppe of the Western USA. Most inferences on factors influencing recovery are based on one-time measurements taken as a snapshot in time, usually focused on the short-term initial establishment phase or outcomes observed decades after. We measured factors associated with the secondary establishment of big sagebrush in nearly 2000 plots across a heterogeneous landscape five years after a megafire (115,000 ha) and the diverse mosaic of restoration treatments implemented and compare these findings to previously published inferences on initial, first-year germination patterns observed on the same plots.
