Estimating upper stem diameters and volume of Douglas-fir and Western hemlock trees in the Pacific northwest by Krishna P. Poudel, Hailemariam Temesgen, Andrew N. Gray

“…The RMSE obtained from taper-based volume estimates were also comparable with the RMSE of the FIA-PNW volume equations for Douglas-fir and western hemlock trees respectively. …”

Analysis of Classification Methods for Identifying Stands for Commercial Thinning Using LiDAR by Bryce Frank, Francisco Mauro, Hailemariam Temesgen, Kevin R. Ford

“…Using a set of 653 fixed radius plots and a coincident LiDAR acquisition, we compared three different classification methods to predict CT eligibility for Douglas-fir (Pseudotsuga menziesii) stands in southwestern Oregon. …”

Spatial Bayesian models project shifts in suitable habitat for Pacific Northwest tree species under climate change by Karin Kralicek, Jay M. Ver Hoef, Tara M. Barrett, Hailemariam Temesgen

“…Climate change impacts were the most damaging for noble fir (Abies procera), for which 79%–100% of the current range was projected to become climatically unsuitable by the 2080s. Although coastal Douglas‐fir (Pseudotsuga menziesii var. menziesii) has been projected by others to gain habitat in Canada, within our study area we projected a net loss of climatically suitable habitat (ca. 8000–31,400 km2) under three of four future climate scenarios. …”
