Landscape change in Tuolumne Meadows, Yosemite National Park, California, was characterized using data derived from four lidar surveys: one airborne survey in 2006 and three terrestrial surveys in 2016, 2017, and 2018. These surveys were used to generate a better quantitative understanding of changes associated with fluvial processes along the reach of the Tuolumne River where it crosses Tuolumne Meadows.

Lidar was collected over the Illilouette Basin in Yosemite National Park, California between August 19th and August 21st 2011 for the USFS Pacific Region. This dataset covers over 42,000 acres ( over 170 km2)

These data were acquired in October 2015 after the Soda Fire burned approximately 280,000 acres of sagebrush steppe in the northern portion of the Reynolds Creek Experimental Watershed, Owyhee County, Idaho in August of that year. This dataset was collected for Kathleen Lohse, Idaho State University, Department of Biological Sciences, and Mark Seyfried, USDA-ARS Northwest Watershed Research Center. The requested survey area is located approximately 55 km southwest of Boise, ID. The polygon encloses approximately 150 km2.

This lidar dataset was collected as part of an NCALM Seed grant for James Guilinger at the University of California, Riverside. This study investigated source attribution of eroded sediments from post-fire runoff events using nested scales of sequential change detection. The study area covers approximately 61 km 2 near Leach Canyon in the Santa Ana Mountains of California.

This lidar dataset was collected as part of an NCALM Seed grant for Brooke Hunter at the University of Oregon. This study used airborne lidar to detect Post-Fire Debris Flow Detection and Erosion from the Douglas Fire near Grants Pass, Oregon. The study area covers approximately 60 km2.

This lidar dataset was collected for William Krugh at California State University, Bakersfield as part of the Center for Climate and Natural Resource Solutions for Water-limited Regions project. This project is part of NSF's Center for Research Excellence in Science and Technology (CREST) program. Roughly 252 km2 of data were collected over the Kern River Canyon east of Bakersfield, CA.

This table contains geographic information defining watersheds that were burned in large wildfires (greater than 100 square kilometers) that occurred in California or California-draining regions (i.e., upper Klamath watershed) between the years 1984 and 2021. Each wildfire was broken into tens to thousands of small watersheds, and each row of this table contains geographic information defining a single watershed.

This data release contains point clouds obtained from three terrestrial laser scanner (TLS) surveys of a hillslope (NAD 83/11 N/ 412828E/ 3780128N) burned by the 2016 Fish Fire in the San Gabriel Mountains, CA, USA. The TLS surveys were completed with a Leica ScanStation C10. The first survey was made on 19 November 2016 prior to the first post-wildfire rainstorm. The second survey was performed on 5 January 2017. Two runoff-generating rainstorms occurred between the first and second surveys. The two rainstorms had peak fifteen-minute average rainfall intensities of 27 mm/h and 10 mm/h, respectively. The third survey was performed on 22 February 2017, following five additional runoff-generating post-wildfire rainstorms. Peak fifteen-minute average rainfall intensities for the five rainstorms were 8 mm/h, 11 mm/h, 16 mm/h, 25 mm/h, and 38 mm/h, respectively. Maps of hillslope erosion derived from the TLS data can be used to document hillslope erosion resulting from these two sets of rainstorms, including the initiation and growth of a substantial rill network. Additional details and a description of the study site can be found in the journal article: Hui T, McGuire LA, Rengers FR, Kean JW, Staley DM, Smith JB. Evolution of debris flow initiation mechanisms and sediment sources during a sequence of post-wildfire rainstorms. Journal of Geophysical Research. 2018.

This lidar dataset was collected as part of an NCALM Seed grant for Thomas Herbst at the University of Missouri. This project explored Lava Domes, and mapped a portion of the Lassen Volcanic Center in Lassen Volcanic National Park, California. The dataset was collected in 2019 and covers roughly 55 km 2

Lidar was collected in the fall of 2014 and spring of 2015 for the USFS Pacific Region 5 sites in California. Data were collected to aid the United States Forest Service in assessing topographic and geophysical properties, as well as supporting ecological restoration planning, and assessing existing conditions of area forests. The Freds Fire project area covers over 150,000 acres (> 600 km 2)
