Abstract:

Forest stands at Blacks Mountain Experimental Forest (BMEF) in northeastern California have undergone changes since the establishment of the Experimental Forest in 1934. Twelve stands were selected exhibiting a range of past management activities to establish metrics describing tree density and stocking conditions in small trees (regeneration) at Blacks Mountain. Methods chosen for plot size and configuration were designed to be similar to those used in an earlier effort (in 1933 and 1934) that quantified trees less than 3.6 inches breast height diameter. We recorded seedling and sapling counts by species group and size class at BMEF in the summer and fall of 2018. In addition to the 2018 data, this data publication also includes the compartment summary data from 1933 and 1934. Data are provided as comma-separated values (CSV) files, but scanned field sheets from 2018 are provided as well as a scan of the work by R.H. Mors in 1936 as Portable Document Format (PDF) files. Also included are PDF files of all references noted in the methods section.
