Title: Optimizing performance of tree planting treatments after severe wildfire

Project Proposal Abstract: Tree recruitment in large, high-severity patches burned in wildfires in western U.S. yellow pine and mixed-conifer forests is often limited. Seed input from surviving trees is usually low, while regeneration of shrubs and herbaceous plants is often strong and rapid. Land managers, including federal agencies, often aim to increase and accelerate tree recruitment by implementing tree seedling planting treatments. Despite wide application of such planting treatments, however, there has been little empirical measurement or analysis of the relative performance of natural regeneration vs. planted regeneration in these areas, and no direct testing of different planting strategies such as timing (first or second year vs. later years) and species composition. In recent work that involved surveying over 2000 plots on 13 fires in the Sierra Nevada of California, we demonstrated that natural post-fire regeneration responses strongly depend on both seed availability and post-fire precipitation and moisture availability. We propose to extend this work on natural regeneration to address the relative contributions of planted and natural seedlings to post-fire recovery trajectories by performing an extensive set of new surveys in paired planted and unplanted plots along environmental gradients in 5-6 fires in the northern Sierra Nevada Our work will yield detailed empirical measures of tree seedling planting performance and background natural regeneration, link these to their environmental drivers, and assess the impact of management choices including the location and timing of planting treatments. The results will also include a decision support tool for location and timing of planting treatments and a data set for use in ground-truthing the US Forest Service eDaRT remote sensing system.
