Abstract:

This data publication includes long-term ecosystem datasets generated from the Forest Residues Utilization Research and Development Program's study at the Coram Experimental Forest, which is nested within the Flathead National Forest in northwest Montana. This multi-disciplinary study was developed in 1973 and implemented in 1974 by scientists in the Forest Service Rocky Mountain Research Station (then, Intermountain Forest and Range Experiment Station) in the cool, western larch-mixed conifer forest of the northern Rocky Mountains ecoregion. Four utilization treatment levels (a combination of biomass utilization level and residue burning treatment) were applied within each of three silvicultural harvests (clearcut, shelterwood, and group selection) with 2 replications. In addition to conventional timber removal, the four utilization levels were specified to (1) cut understory, remove residue, and broadcast burn; (2) cut understory, leave residue, and broadcast burn; (3) cut understory, remove residue, and do not burn; and (4) do not cut understory, remove residue, and do not burn. These experimental harvests and prescribed burning took place in 1974-1975, and data were collected between 1973 and 2013. There are four core sets of data included in this publication: tree, shrub, plantation, and forest floor. A suite of tree (including natural and planted) measurements were taken in 2012 such as height, diameter at breast height, live crown base height, species, and seedling counts. In 1973, 1976, and 1978 non-tree woody vegetation (shrub) data such as crown diameter, height, density, and species were measured. In 2012 shrub basal diameter (of root crown) was also recorded. Plantation data such as vigor, crown position, tree height, diameter at breast height, crown length and width, etc. were recorded up to 10 times between 1977 and 2013. In 2013, forest floor depth and mineral soil materials were also measured.
