Biophysical settings were developed by the LANDFIRE program and fires occurences were mapped by the Monitoring Trends in Burn Severity (MTBS) program. Categories: Data; Types: Citation, Downloadable, GeoTIFF, Map Service, Raster; Tags: California, Mojave Desert, biophysical settings, deserts, wildfire frequency Ecological zones of California deserts The dataset delineates ecological zones within California deserts. We derived ecological zones by reclassifying LANDFIRE vegetation biophysical setting types, plus defined various non-wildland (e.g. developed urban/agriculture/roads) and non-burnable (e.g. open water/barren) areas using LANDFIRE existing vegetation types. The 43 biophysical setting types present within the study area were grouped into 13 general vegetation types, which were further grouped into 4 elevation-based ecological zones plus one riparian zone according to their constituent plant associations.

The data release includes basic information about each event such as location, volume, area, and runout distances as well as information about seismic detections and the location of seismic data, photos, maps, GIS files, and links to papers, websites, and media reports about the event. Not all record types exist for each event, and the quality of the information varies from event to event.

These deserts occupy the southeastern portion of California and include two ecoregional provinces comprised of five desert regions ("ecological sections"; Miles and Goudey 1997). The American Semi-Desert and Desert Province (warm deserts) includes the Mojave Desert, Sonoran Desert, and Colorado Desert sections in the southern 83% of the California desert. The Intermountain Semi-Desert Province (cold deserts) includes the Southeastern Great Basin and Mono sections in the northern 17% of the region.

Sonoran Desert, deserts, wildfire regimes, Fewer tags Classified point cloud and gridded elevation data from the 2005 B4 Lidar Project, southern California, USA This data set is derived from the original 2005 data collected over the southern San Andreas and San Jacinto fault zones in southern California, USA. These data have provided a fundamental resource for study of active faulting in southern California since they were released in 2005. However, these data were not classified in a manner that allowed for easy differentiation between bare ground surfaces and the objects and vegetation above that surface. This reprocessed (classified) dataset allows researchers easy and direct access to a "bare-earth" digital elevation data set as gridded half-meter resolution rasters (elevation and shaded relief), "full-feature" digital elevation models as gridded one-meter resolution...

These data were collected during the spring 2016 range-wide census. The USGS range-wide sea otter census has been undertaken twice a year since 1982, once in May and once in October, using consistent methodology involving both ground-based and aerial-based counts. The spring census is considered more accurate than the fall count, and provides the primary basis for gauging population trends by State and Federal management agencies.

The field boundaries in this data set are digitized from one-year composite maximum NDVI data derived from atmospherically corrected Landsat 2 Multispectral Scanner (MSS), Landsat 5 MSS, and Landsat 5 Thematic Mapper (TM) scenes. NDVI was calculated from the corrected reflectance data for each selected scene during the growing season (May through early October) and a single, composite image of maximum NDVI values was derived for each 5-year interval.
