C05d Attachment 5 Current Invasive Acres 1284LM26Q0090.xlsx

This is a GIS dataset file containing current invasive plant acreage data for the Payette National Forest in Idaho. The spreadsheet tracks 214 individual invasive plant infestation records across multiple species, including gypsyflower, rush skeletonweed, Canada thistle, spotted knapweed, butter and eggs, Dalmatian toadflax, sulphur cinquefoil, common St. Johnswort, bull thistle, and approximately 25 other invasive species. The dataset captures spatial information, treatment priority classifications, infestation percentages, cover percentages, distance to water measurements, and acreage calculations derived from GIS analysis. Records span collection dates from 2001 through 2021, with most recent updates in 2021, and include examiner names, plant status designations (ranging from "Priority One - New Invaders" to "Priority Two - Established Infestations"), and specific location identifiers tied to the Payette National Forest administrative unit.

The total invasive plant coverage documented across all records is approximately 33,906 acres, with the largest infestations being gypsyflower at 6,965 acres, rush skeletonweed at 6,053 acres, and Canada thistle at 4,220 acres. The data identifies three named project areas within the dataset: LAVA (1,417 acres), Limepoint (615 acres), and blank/undesignated areas (31,873 acres). Each record includes detailed GIS metrics such as SHAPE_Length and SHAPE_Area measurements, with NEW_GIS_Acres calculations providing standardized acreage figures used for monitoring infestation progression and treatment planning. This dataset directly supports the USDA Forest Service's Disaster Relief Invasive Treatments BPA Call Order for the Payette National Forest by providing comprehensive baseline inventory and spatial reference information for invasive plant management activities.
