Tree density, size, and composition data for mixed-conifer forest in the Deschutes and Ochoco National Forests

This data publication contains 171 site samples of tree density measurements recorded in mixed-conifer forests of central Oregon in the Deschutes and Ochoco National Forests collected in the summers of 2009 and 2010. Density measurements are available for three common species and all other species: 1) grand and white fir; 2) ponderosa pine; 3) Douglas-fir; and 4) all species not including grand fir, white fir, ponderosa pine or Douglas-fir. Data are also available in four diameter at breast height classes: 10-29.9 centimeters (cm), 30-49.9 cm, 50-69.9 cm, and >70 cm. These data were collected to describe and identify current structure and composition of mixed-conifer forests and successional trajectories following fire exclusion and logging. Original data are currently archived with Andrew Merschel at Oregon State University: 321 Richardson Hall 3200 SW Jefferson Way Corvallis, OR, USA 97333 Original metadata date was 12/01/2014.
