The target population for the terrestrial master sample consists of all BLM-managed lands in the western contiguous U.S. For the terrestrial master sample, no attempt was made to identify or exclude non-suitable land cover types (e.g., water) within BLM-managed lands. This was because of the variable extent/coverage of these features and difficulty in accurately defining them in national-level datasets. The initial master sample draw was conducted for all BLM lands throughout WA, OR, CA, ID, NV, AZ, NM, UT, CO, WY, MT, ND, and SD.

The sample frame was derived from the BLM’s Surface Management Agency geospatial layer (updated as of July, 2015). All BLM-managed lands within the 13 states listed above were considered within the sample frame.

The terrestrial master sample was originally drawn for all BLM lands in the 13 states at a density of approximately 1 point per 10ha. This gives a total of 6,988,649 sample points. Revised to 1 point per 35ha, giving a total of 2,000,194 sample points.
