The downloadable ZIP file contains an number of Esri shapefiles as described below.\\u00a0 This data set provides the spatial information used to complete a post fire inventory and assessment for the 2015 Clearwater Fire in Idaho, Clearwater, and Lewis Counties, Idaho.\\u00a0 The fire burned 47,478 acres within Idaho, Clearwater, and Lewis Counties, Idaho in August 2015.\\u00a0 Data was prepared by several agencies including US Forest Service, USDA Natural Resources Conservation Service, Nez Perce Tribe, Idaho Department of Lands, and the Nez Perce Soil and Water Conservation District.
Several data sets are available and are described as follows:
Burn Severity: This data set reflects the fire burn severity and classifies intensity in to three categories. Data field verified and processed by the US Forest Service, Nez Perce and Clearwater National Forests, Orofino, Idaho. Shape files and KMZ files are included. Files are named ClearwaterComplexFireBurnSeverity or ClearwaterComplex_SBS.
Fire Boundary: Data shows the 2015 fire boundary. Data generated by US Forest Service. File name: 20150826_0002_MDT_ClearwaterComplex_IR_HeatPerimeter or Clearwater Complex Fire Boundary.
Hillslope Erosion: Within the fire boundary, hillslope erosion rates were identified. Data was organized into one of four categories; low (0-1 tons/acre), moderate (1-10 tons/acre), high (10-50 tons/acre), and very high (>50 tons/acre). Potential hillslope erosion was estimated using the GeoWEPP model. GeoWEPP is a geo-spatial interface for WEPP (Water Erosion Prediction Project). GeoWEPP Model Runs completed by Mary Miller, Michigan Tech Research Institute and USFS Rocky Mountain Research Station, Moscow, Idaho. Map Generated by Nikki Lane, Nez Perce Soil and Water Conservation District. June 2016. Files named ClearwaterComplexGeoWepp
Land Cover: Land cover categories generated from National Land Cover Database (2011, USGS). Data processed by clipping NLCD by 2015 fire boundary. Fire boundary generated from InciWeb. Categories include; Developed, Open Space - Mix of constructed materials, but mostly lawn grasses. Impervious surfaces < 20% of total cover. Deciduous Forest - >20% deciduous trees. Evergreen Forest - >20% evergreen trees. Mixed Forest \\u2013 >20% trees with mix of deciduous and evergreen trees. Shrub/Scrub >20% shrub vegetation. Grassland/Herbaceous - >80% grass /other herbaceous vegetation. Pasture/Hay - Areas of grasses, legumes, or grass-legume mixtures planted for livestock grazing or the production of seed or hay crops, typically on a perennial cycle. Cultivated Crops Areas used for the production of annual crops and/or being annually tilled. Woody Wetlands \\u2013 Soils that are periodically saturated or covered with water and contain >20% forest or shrubland vegetation. Emergent Herbaceous Wetlands Soils that are periodically saturated or covered with water and vegetation is >80% herbaceous. Data generated by Nikki Lane, Nez Perce soil and Water Conservation District. Jan 2016. Files are named ClearwaterComplexLandCoverFINAL1_5_15
Land Ownership: Ownership layer for 2015 fire boundary. Source data is BLM Federal Land Status layer clipped to 2015 fire boundary obtained from InciWeb. Bureau of Land Management (BLM); Surface Management Agency (Federal Land Status) layer. 2011. (http://insideidaho.org). Data generated by Cody Dawes, Nez Perce Soil and Water Conservation District. January 2016. Ownership categories: BLM \\u2013 Bureau of Land Management, Private \\u2013 private, USFS \\u2013 US Forest Service, IR \\u2013 Indian Reservation, State \\u2013 State of Idaho. Files are named ClearwaterComplexOwnershipFINAL1_6_2016
Slope Class: Data generated from USGS Digital Elevation Model to identify slopes. Slopes were divided into 3 classes; 1-20, 21-40;>40. Data generated within 2015 fire boundary areas as identified by US Forest Service. Data generated by Nikki Lane, Nez Perce Soil and Water Conservation District. January 2016. Files are named ClearwaterSlopeClassFinal or ClearwaterComplexSlopeClassFINAL_1_7_16.
Streams: Data shows streams (perennial and intermittent) within the Wash Complex 2015 fire boundary. Streams layer obtained from USGS. U.S. Rivers and Streams represent detailed rivers and streams in the United States. Data clipped and processed by Cody Dawes, Nez Perce Soil and Water Conservation District in January 2016. Files named ClearwaterComplexStreamNames
PrivateForestlandsBySlope: Data shows three slope classes (0-20, 20-40, >40) on private owned forestlands. Data generated from BLM ownership layer, USGS Digital Elevation Model, and the National Land Cover Database. Data generated by Cody Dawes, Nez Perce Soil and Water Conservation District. January 2016. File name ClearwaterForestedAreaonPrivateLandBySlope or ClearwaterComplexPrivateForestLandSlopeClassesFINAL_1_7_16.
Private land forested acres: Data shows privately owned forest acres burned during the 2015 event. Data generated by Cody Dawes, Nez Perce Soil and Water Conservation District. January 2016. File name ClearwaterComplexForestedAcresOnPrivateLand
Post Fire Debris Flow Analysis for stream segments: USGS post fire debris flow hazard analysis for stream segments within the 2015 fire boundary. Debris flow hazard classified as low (stream segments with low probability of debris flow occurrence and smallest debris flow volume), moderate (stream segments with relatively low probability of occurrence and larger debris flow volume estimates) and high (high probability of occurrence and large debris flow volume estimate). File names contain the wording clw2015_segment_dfpredictions_25yr or ClearwaterComplexSegmentHazard25yr.
Post Fire Debris Flow Analysis for basins: USGS post fire debris flow hazard analysis for basins within the 2015 fire boundary. Debris flow hazard classified as low (basins with low probability of debris flow occurrence and smallest debris flow volume), moderate (basins with relatively low probability of occurrence and larger debris flow volume estimates) and high (high probability of occurrence and large debris flow volume estimate). File names contain the wording clw2015_basin_dfpredictions_25yr or ClearwaterComplex25YRbasinVolume.
Planting Groups: Data layer contains forest planting groups as identified by USDA Natural Resources Conservation Service. Data reflects private lands within the 2015 burned area that were forest land cover. Data compiled by Frank Gariglio, USDA NRCS Idaho State Forester, and Brian Gardner, USDA NRCS IDaho Soil Scientists. GIS layer processed by Nez Perce Soil and Water Conservation District. Data layer generated January 2016. Files named clearwatercomplexplantinggroups or ClearwaterComplexReforestationPlantingGroupDesignationV1.0. Planting Group Descriptions:
Group 0 - burned areas that are assumed to be PIPO (Pinus Ponderosa)
Group 1 - PIPO (Pinus ponderosa) only
Group 2 - PIPO (Pinus ponderosa) dominant, with some PSMEC (Pseudotsuga menziesii (Mirb.) Franco var. glauca (Beissn.)) Rocky Mountain Douglas-fir
Group 3 - PSMEG( Pseudotsuga menziesii) Rocky Mtn Douglas Fir and PIPO (Pinus ponderosa) with some LAOC (Larix occidentalis Nutt.) western larch
Group 4 - PSMEG (Pseudotsuga menzeisii), LAOC (Larix occidentalis) and possibly PIPO (Pinus ponderosa) and PICO (Pinus contorta) Lodgepole Pine
Group 5 - PSMEG (Pseudotsuga menzeisii), LAOC (Larix occidentalis) and possible PIEN (Picea engelmannii Parry ex Engelm.) Engelmann spruce and PICO (Pinus contorta) Lodgepole Pine
