The data support a study that surveyed the spatial distribution of Oncorhynchus mykiss and Cottus aleuticus eDNA in coastal streams of Big Sur, California, 2021-2022 following post-fire debris flows. The metadata represent qPCR quantification cycle (Cq) values for O. mykiss and C. aleuticus assays performed on water samples collected during June and July of 2021 and 2022 from the following streams: Big Creek, Mill Creek, Prewitt Creek, and Willow Creek. The metadata also includes the distance (meters) of each eDNA sample site from the stream mouth, volume of water (Liters) collected for eDNA analysis at each site, and the Y-intercept, slope, and R-squared value for each assay run.
This tabular, machine-readable CSV file contains annual phenometrics at locations in ponderosa pine ecosystems across Arizona and New Mexico that experienced stand-clearing, high-severity fire. The locations represent areas of vegetative recovery towards pre-fire (coniferous/pine) vegetation communities or towards novel grassland, shrubland, or deciduous replacements. Each sampled area is associated with the point location (latitude/longitude) as well as multiple calendar year phenometrics derived from the time-series of normalized difference vegetation index (NDVI) values in the phenology software package Timesat v3.2.
Rainfall measurements were collected in and near the Dolan Fire burn area, Los Padres National Forest, California. The CZU Fire ignited in Los Padres National Forest, California, on August 18, 2020. By the time of full containment on December 31, 2020, the fire had burned 518 km2 (128,050 acres) in Monterey County. The U.S. Geological Survey (USGS) installed seven rain gages in and near the Dolan Fire burn area in October 2021 to measure rainfall during two post-fire wet seasons. This data release contains rain records from the Mill Creek and upper Nacimiento River watersheds collected during water year 2023 (October 1, 2022, through spring 2023). Previous datasets from this region included an additional rain gage...

These data provide on-the-ground estimates of burn severity as estimated by the Composite Burn Index (CBI) for fires that burned between 1994 and 2018. Landsat imagery was subsequently used to develop regression relationships between the Normalized Burn Ratio (NBR) and differenced NBR (dNBR).
Rainfall measurements were collected in and near the Dolan Fire burn area, Los Padres National Forest, California. The Dolan Fire ignited on August 18, 2020. By the time of full containment on December 31, 2020, the fire had burned 518 km2 (128,050 acres) in Monterey County. Post-fire debris flows occurred in many watersheds burned by the Dolan Fire during the first post-fire wet season, in winter 2021. The U.S. Geological Survey (USGS) installed seven rain gages within the Dolan Fire burn area in October 2021 to measure rainfall during the second post-fire wet season. The USGS gratefully acknowledges permission granted by Los Padres National Forest for the collection of these data.

Invasion of exotic annual grasses (EAG) and increased wildfire have led to an emphasis on managing rangeland plant communities for resistance to invasion and resilience to disturbances. In sagebrush steppe and similar rangelands, perennial bunchgrasses and particularly their roots are hypothesized to be primary contributors to the resistance and resilience. We asked how bunchgrass root abundance relates to annual grass invasion and aboveground indicators of bunchgrass vigor that are more readily measured, such as plant height. We used a standardized USDA protocol for root measurement in 445 excavations made in 2016-2018 across a topographically and ecologically varied region of sagebrush steppe burned in the 2015...
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 2021 Horne Fire on Isle Royale National Park (ISRO) ignited when lightning struck the island near Duncan Bay on August 10, 2021, during elevated drought conditions. Per the National Park Service, it would continue to burn slowly and spread until a wind event on August 21, 2021 caused significant spread and initiated a control effort to protect historical structures in Tobin Harbor. The fire was 75% contained by September 6, 2021, and allowed to smolder until winter rain and snow finally extinguished the fire. The Horne Fire became the third-largest wildfire in the park’s history, necessitating a detailed assessment of landscape responses to spatial variability in burn severity. These data were created by comparing...

This dataset contains demographic data pertaining to Hesperocyparis forbesii on Otay Mountain in San Diego County, California, USA, over a 14-year study period from 2004 to 2017 following the 2003 Otay/Mine Fire. Site variables including elevation, incline, and slope were collected as well as pre-fire tree density and stand age for 16 study site locations. Tree density, height, and cone production was then monitored over the study period with data collection occurring in 2004, 2005, 2009, 2011, 2014, and 2017. These data support the following publication: Brennan, T.J. & Keeley, J.E., 2019, Postfire population dynamics of a fire-dependent cypress, Plant Ecology, 220(6): 605. https://doi.org/10.1007/s11258-019-00939-8

These data provide on-the-ground estimates of burn severity as estimated by the Composite Burn Index (CBI) for fires that burned between 1994 and 2018. Landsat imagery was subsequently used to develop regression relationships between the Normalized Burn Ratio (NBR) and differenced NBR (dNBR).

Rainfall measurements were collected in and near the CZU Lightning Complex Fire (hereafter, "CZU Fire") burn area, Santa Cruz Mountains, California. The CZU Fire ignited in the Santa Cruz Mountains, California, on August 16, 2020. By the time of full containment on September 22, 2020, the fire had burned 350 km2 (86,510 acres) in Santa Cruz and San Mateo Counties. The U.S. Geological Survey (USGS) installed four rain gages in and near the CZU Fire burn area to measure rainfall during two post-fire wet seasons. The USGS gratefully acknowledges the cooperation of Big Basin Redwoods State Park, the Big Creek Lumber Co., the McCrary family, and Brookdale Lodge in the collection of these data.

These data provide on the ground estimates of burn severity as estimated by the Composite Burn Index (CBI). Data were collected between 1996 and 2018 for fires that burned during this time period. Landsat imagery was used to develop regression relationships between the Normalized Burn Ratio (NBR) and differenced NBR (dNBR).
These data were compiled for/to provide an example and assess methods and results of pre-fire estimation of predicted differenced normalized burn ration (dNBR) for predicting post-fire debris flow hazard classification. Objective(s) of our study were to develop predictive models for burn severity, using variables of pre-fire conditions, for two large wildfires from 2020 in Colorado, USA. These data represent pre-fire predictions of post-fire differenced normalized burn ratio (dNBR) as a proxy of burn severity and further understand pre-fire modeling of burn severity. These data were collected/created in the fire perimeters the East Troublesome Fire (10/14/2020 – 11/30/2020) and the Grizzly Creek Fire (8/10/2020...
Raw aerial photography, orthorectified imagery, point cloud data, and digital elevation models (DEMs) for Whiskeytown National Recreation Area (NRA) following the Carr Fire. Sites within the NRA include: Lower Crystal Creek, Tower House, Grizzly Gulch, Boulder Creek South Shore and Conifer, Brandy Creek Camp, Shasta Divide, Paige Bar (North, NEED Camp, East, and Southeast), Chinese Laundry, and Coggins Park. Imagery was collected with two sensors (Ricoh GR II and MicaSense RedEdge) on a quadcopter flown at 400 feet above ground level immediately following the Carr Fire (October 2018) and 8-9 months after the fire (May and June 2019). Due to access, not all sites were flown during both collection periods. U.S. Geological...
