2. How significant are the roles of pathogens and insects in the forest change?
3. How...
Tree damage following dust abatement/road
stabilization treatment was evaluated on 12.5
miles of the Selway River Road, Nez Perce
National Forest. Calcium chloride was applied in
June of 2000, mostly at a rate of 51b/yd2 (18,600
lb./acre) or 6.9 lb/yd 2 (25,700 lb/acre). 1,189
trees up to 30 feet from...
White pine plantations which were established in 1968 on 88 acres of the Palouse Ranger District, Clearwater

Western gall rust (Endocronartium harknessii) and pine bark aphids (Pineus sp.) were present on 6.6 and 2.5 percent of collections, respectively. Cylcaneusma...
Two thousand and thirty-nine trees on 213 plots are being monitored yearly for

District of the Idaho Panhandle National Forests are the site of the project.
Relationships between factors such as species, aspect, slope, elevation,
habitat type, stand appearance...
