A 12-year-old ponderosa pine plantation on the Tahoe National Forest in northern California was mechanically treated with a Hydro-Ax in an attempt to increase the survival and growth of the planted seedlings. Other release methods were not feasible because the shrubs in the mixed-shrub community ...

A provenance test of 49 seed sources of Scots pine (Pinus sylvestris L.) from eastern Europe, Russia, and Siberia was established in two plantations in north-central North Dakota. After 22 years, trees from seed sources within the region bounded by 20° to 57° east longitude and 50° to 58° north l...

A microcomputer-based soil temperature model was developed to predict temperature at the litter-soil interface and soil temperatures at three depths (0.10 m, 0.20 m, and 1.25 m) under closed forest canopies. Comparisons of predicted and measured soil temperatures indicated good model performance ...
