Tepley&Veblen2015_transect_data

Forest stand- and age-structure-data were collected across two ca. 1,340-ha study areas (Squaretop Mountain and Williams Creek) located within the San Juan National Forest of southwestern Colorado as part of a study to evaluate historical fire regimes and fire-driven forest dynamics across the moisture gradient of mixed-conifer and aspen forest. Within the data file, a separate sheet is provided for each of the following datasets: (1) transect locations, (2) overstory (> 15 cm dbh) species composition and size structure, (3) ages of overstory trees, (4) sapling (1.5–15.0 cm dbh) density, (5) the forest type for each transect, and (6) codes for species used in the other datasheets
