Restoration of a Rocky Mountain Spruce-Fir Forest: Sixth-Year Engelmann Spruce Seedling Response With or Without Tree Shelter Removal

This paper presents results following 6 growing seasons of a project designed to examine the use of tree shelters as a means to provide initial shade for planted Engelmann spruce seedlings. Seedlings were planted in 1996 on a 48-ha (119-ac) high-elevation site with different colors of tree shelters providing various degrees of shading. A control treatment, consisting of shading using debris wit...

Forest Development and Carbon Dynamics after Mountain Pine Beetle Outbreaks

Mountain pine beetles periodically infest pine forests in western North America, killing many or most overstory pine stems. The surviving secondary stand structure, along with recruited seedlings, will form the future canopy. Thus, even-aged pine stands become multiaged and multistoried. The species composition of affected stands will depend on the presence of nonpines and outbreak severity, am...

Site factors determining epiphytic lichen distribution in a dieback-affected spruce-fir forest on Whiteface Mountain, New York: stemflow chemistry

Epiphytic lichen diversity in a dieback-affected forest of red spruce (Picea rubens Sarg.) and balsam fir (Abies balsamea (L.) Mill.) on Whiteface Mountain, New York, U.S.A., was higher on dead compared with living trees and on fir compared with spruce. Diversity differed more between living and dead spruce than between living and dead fir. Cover of all lichen species that occurred on more than...

Nutrient Dynamics and Decomposition rate of Norway Spruce Needles in Stråsan and Lajim stands

     Climate changes due to changes in a habitat leads to differences in the rate of decomposition and nutrient dynamics of leaflitters, which has many effects on the controlling factors of the decomposition process. In the present study, the rate of decomposition and nutrient dynamics of Norway spruce was evaluated for 363 days in the two forestation sites in the natural and foreign habitats, ...
