Wildfire can impact soil-physical and soil-hydraulic properties, with major implications for hydrologic and ecologic response. The durations of these soil impacts are poorly characterized for some forested environments. This dataset sheds light on the first four years of recovery of soil-physical properties of bulk density, loss on ignition (measure of soil organic matter), ground cover, and soil particle size distribution and of soil-hydraulic properties of sorptivity and field-saturated hydraulic conductivity. The dataset also includes a simple infiltration model used to examine infiltration as the sites recover from fire.

This Data Release summarizes measurements of hydraulic and physical properties of soils and ash at sites in the area impacted by the 2017 Thomas Fire, USA. Physical properties include dry bulk density, loss on ignition, and saturated soil water content. Hydraulic properties include field-saturated hydraulic conductivity, sorptivity, Green-Ampt wetting front potential, and soil water retention. These measurements provide a foundation to reduce uncertainty of parameters in hydrologic models used to predict water-related hazards, water quality, and water quantity. Note that all methods of data acquisition and processing, column headings, and data annotations are explained in the metadata files.

The practice of fire suppression across the western United States over the past century has led to dense forests, and when coupled with drought has contributed to an increase in large and destructive wildfires. Forest management efforts aimed at reducing flammable fuels through various fuel treatments can help to restore frequent fire regimes and increase forest resilience. Our research examines how different fuel treatments influenced burn severity and post-fire vegetative stand dynamics on the San Carlos Apache Reservation, in east-central Arizona, U.S.A. Our methods included the use of multitemporal remote sensing data and cloud computing to evaluate burn severity and post-fire vegetation conditions as well as statistical analyses. We investigated how forest thinning, commercial harvesting, prescribed burning, and resource benefit burning (managed wildfire) related to satellite measured burn severity (the difference Normalized Burn Ratio – dNBR) following the 2013 Creek Fire and used spectral measures of post-fire stand dynamics to track changes in land surface characteristics (i.e., brightness, greenness and wetness). This dataset includes all of the attribute information for each point, including if the location of the point intersects a treatment type or combination of treatments as well as a KML file showing the location of each point.

Disturbance disrupts the balance between gross primary productivity and respiration, resulting in a net C loss for some time after a stand-replacing fire. However, our understanding of this process is based on a limited number of studies. Ecosystem C recovery post-fire must be explicitly and carefully examined in order to generate accurate predictions of C cycle impacts of future wildfires and change in fire regimes. Montane ponderosa and lodgepole pine forests, either single-species stands or mixed, dominate surface area in the Southern Rockies. These species have drastically different relationships with wildfire; the current narrative portrays ponderosa pine as accustomed to low-severity surface fires with low regeneration rates following high-severity wildfire, whereas lodgepole pine forests readily regenerate after a high-severity stand-replacing wildfire. Forests at the transition between lower montane and upper montane may be more sensitive to future climate change than their lower counterparts; e.g., a stand-replacing disturbance could cause montane ponderosa pine forests to yield to lodgepole pine. It is important to understand how wildfire impacts ecosystem C fluxes in these ecosystems and how landscape dynamics, including topographical changes in climate and distance from forest seed source, can be used to predict C cycle responses to future wildfire patterns. To date, no single study has collected data at an adequate temporal resolution to fully characterize the short-term, intermediate-term, and long-term response and recovery of forest soil respiration to pre-burn conditions. The aim of this work is to predict soil respiration and net primary productivity in pine forests of the southern Rocky Mountains based on time since fire, fire severity, forest type, and forest and soil properties, such as tree basal area, leaf area index and soil carbon pools. We sampled 5 wildfires and 1 high-severity prescribed fire as well as nearby unburned reference forests. The following time-since-fire intervals were sampled along a 30-yr chronosequence: 1-5 years (n=1), 5-10 years (n=1), 10-20 years (n=3), and 20-25 years (n=1).
