About this file

This is a Bureau of Land Management (BLM) Infestation Record form used for documenting invasive plant species on federal lands within the Medford District of Oregon, which includes resource areas in Ashland, Butte Falls, and Grants Pass.

The form captures detailed field survey data on invasive plant infestations, including date of observation, species identification via standardized codes, plant count measurements (per acre, hectare, square feet, square meter, or total area), count methodology (actual, estimate, ocular estimate, or transect), estimated percent cover (trace, low 1-5%, medium 5-25%, or high 25-100%), distribution pattern (isolated, clumped, scattered, or pervasive), phenological stage (pre-bud, flowering, seed set, mature, senescent, bolt, vegetative, rosette, or bare ground), geographic coordinates, and optional comments. The document includes a comprehensive species code reference list containing approximately 90 invasive plant species common to the region, such as yellow starthistle (CESO3), cheatgrass (BRTE), spotted knapweed (CESTM), and numerous thistles, bromes, and other noxious weeds. An example entry from July 2, 2019 documents yellow starthistle with 10,000 plants per total area using ocular estimation methodology, indicating high percent cover in a scattered distribution pattern at flowering stage, covering approximately one-quarter acre.
