Abstract:

This data publication contains original tree data collected in 1933 and 1934. The effort was done to complete a census of all trees greater than 3.5 inches diameter at breast height (dbh) at Blacks Mountain Experimental Forest (BMEF) in Lassen County, California. It was conducted under the supervision of Austin Hasel. This Experimental Forest is approximately 10,000 acres and was subdivided into 2.5-acre spatially-referenced plots for data collection. On each 2.5-acre plot, all trees greater 3.5 inches dbh were tallied by 2-inch diameter class, Dunning vigor class, and species (incense cedar, white fir, or ponderosa pine/Jeffrey pine which were combined for this study). Scans of the original field sheets are included, as well as a tabular digital version of the data.
