Cold Springs Fire Project Fire restoration, disturbance and regeneration
Goal: To achieve an understanding of both post-fire forest dynamics and how pre-burn stand structures influence the effects of wildfire. Stand Structure: Distribution of trees by species and size. Cold Springs Fire, 2016
Background The Cold Springs Fire Fascinating to study! July 9, 2016 Anthropogenic 2 miles North of Nederlands 528 acres in size (USFS InciWeb) Fascinating to study! How have USFS restoration treatments - Influenced the effects of fire on forest? - Influenced regeneration and recovery? USFS Collaborative Forest Restoration, CFLR 2010–2016 Progress The USFS’s Collaborative Forest Landscape Restoration Project 23 CFLR projects across the US Focuses on community engagement Aims to reduce risk of catastrophic wildfire Prescribed fires, slash piles, rearrangement of heavy fuels Cold Springs a part of the Front Range CFLR project Though there were 100s of homes along the fire’s perimeter, the loss was limited to eight residences. Possibly as a result of forest management through the CFLR! Cold Springs Fire
Methodology In situ plot based measurements. Remotely sensed data. Figure 1: Example of the 30m x 30 m plot layout that includes four nested permanent sub-plots (10m x 10 m) and four regeneration sampling transects (2m swaths). In situ plot based measurements. Remotely sensed data. Aerial drone acquisition Monitoring plots Burned + CFLR Burned + untreated Not burned + CFLR Not burned + Untreated
Locations of plots within and around Cold Springs burn perimeter.
Current Progress Plots established Field data collected General census of: - Tree/stem location, species - Downed wood, cones - Metrics of fire effects How do these variables differ among the four disturbance types? Helped with data collection and entry. Right now I’m helping to convert the coordinates of the cones, downed wood and stems to map layers in ArcGIS. Later we hope to integrate these layers with the remote sensing imagery produced by our aerial drones.
Long Term Project Goals Integrate in situ and remote sensing data. Develop models that describe post-disturbance changes in forest structure. Evaluate the impact of the CFLR.
