Front Range Forest Reconstruction Network* 2012 Field Season: 13 Landscape Units 73 0.5 ha plots (3 to 7 plots in each unit) Funded by: Colorado Forest Restoration Institute Arapahoe-Roosevelt National Forest Pike-San Isabel National Forest Rocky Mountain Research Station Boulder County Parks and Open Space Rocky Mountain Tree-Ring Research

  4. FRFRNet Methods: 1. Stem map pre-settlement trees within 0.5 ha plots; -2. Subsample age structure and post-settlement structure in 4 500 m2 subplots; 3. Collect all fire-scar evidence in plot and surrounding area.
