Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability and resilience of different landscapes to permafrost degradation are needed. Geophysical and other field observations reveal details of both near-surface (less than 1 m) and deeper (greater than 1 m) impacts of fire on permafrost along 14 transects that span burned-unburned boundaries in different landscape settings within interior...

The Great Dismal Swamp (the swamp) is a forested peatland in southeastern Virginia and northeastern North Carolina. Since early colonial times, timber harvesting and drainage through a network of ditches constructed to facilitate the harvesting have altered these ecosystems. The U.S. Fish and Wildlife Service has managed the swamp as the Great Dismal Swamp National Wildlife Refuge since 1974 to restore its forest communities to those present in early colonial times. Part of the approach to forest restoration has been to "restore the hydrology." The report by Speiran and Wurster (2020) describes the hydrology and water quality across the swamp. Part of the data used to describe the hydrology and water quality of...

Fire polygons from the "fire history" layer from the BLM Alaska Interagency Coordination Center (www.fire.ak.blm.gov) and the Canadian Interagency Forest Fire Centre (CIFFC) website at (http://www.ciffc.ca) were merged. In Canada, fire polygons from the Yukon, Northwest Territories, and British Columbia. Year was truncated to 1965 because it was the earliest coverage for the 4 datasets (Alaska, Yukon, Northwest Territories, and British Columbia). Fire polygons include information such as fire name and year/month burned.

Extreme climate events– such as hurricanes, droughts, ice storms, extreme precipitation, and wildfires– have the potential to cause large changes in watershed processes, response, and function. A five-year post-wildfire study of stream chemistry in the Colorado Front Range USA, enabled the analysis of the effects these events have water quality, which is published in the journal article Murphy, S.F., McCleskey, R.B., Martin, D.A., Writer, J.H., and Ebel, B.A., in review, Fire, flood, and drought: Extreme climate events alter flowpaths and stream chemistry: JGR-Biogeosciences. That article describes how extreme climate events altered concentration-discharge relations in ways that elucidate hydrologic flow paths and...

Arid ecosystems are often vulnerable to transformation to invasive-dominated states following fire, but data on persistence of these states are sparse. The grass/fire cycle is a feedback process between invasive annual grasses and fire frequency that often leads to the formation of alternative vegetation states dominated by the invasive grasses. However, other components of fire regimes, such as burn severity, also have the potential to produce long-term vegetation transformations. Our goal was to evaluate the influence of both fire frequency and burn severity on the transformation of woody-dominated communities to communities dominated by invasive grasses in major elevation zones of the Mojave Desert of western...

This fire risk assessment was conducted to understand how resilience and resistance and sage-grouse breeding bird habitat may inform wildland fire management decisions including preparedness, suppression, fuels management and post-fire recovery for western sagebrush communities. The assessment is based on the premise that risk = probability of a threat and the consequences of that threat (negative or positive). Fire risk was determined by the probability of a large wildfire and the consequences of fire on greater sage-grouse breeding habitat. These consequences were modified by the capacity of sage-grouse habitat to be resilient and thus recover from fire processes, and be resistant to invasive annual grasses. The...
This data release contains data summarizing observations within and adjacent to the Woodbury Fire, which burned from 8 June to 15 July 2019. In particular, this monitoring data was focused on debris flows in burned and unburned areas.
