In northern Sweden, the availability of arboreal lichens (Bryoria fuscescens, Alectoria sarmentosa) as winter grazing resources is an important element in reindeer husbandry. With the industrialization of forestry, forests rich in arboreal lichens have diminished considerably. Here, we analyze how forestry has impacted lichen availability from the 1920's to the present day and model its future ...

It is well known that C-band repeat-pass InSAR coherence can more accurately predict boreal forest stem volume than microwave radar backscatter. In this paper two boreal forest areas have been studied, one in Finland and one in Sweden. In spite of the small number of forest stands (approximately 40 stands at each site with mean area of 7 ha and stem volume range of 350 m/ha and 550 m/ha) a divi...

We studied the ecological characteristics of 45–50-yr-old subtropical dry forest stands in Puerto Rico that were growing on sites that had been deforested and used intensively for up to 128 yr. The study took place in the Guánica Commonwealth Forest. Our objective was to assess the long-term effects of previous land use on this forest—i.e., its species composition, structure, and functioning. P...

Fungal communities have been shown to be highly sensitive toward shifts in plant diversity and species composition in forest ecosystems. However, little is known about the impact of forest management on fungal diversity and community composition of geographically separated sites. This study examined the effects of four different forest management types on soil fungal communities. These forest m...

Increasing wildfire activity in Alaska's boreal forests has led to greater fuel-reduction management. Management has been implemented to reduce wildfire spread, but the ecological impacts of these practices are poorly known. We quantified the effects of hand-thinning and shearblading on above- and belowground stand characteristics, plant species composition, carbon (C) and nitrogen (N) pools, a...

Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 22 p. We reconstructed the stand structure and composition for two western Washington old-growth forest sta...

Stand development involves changes in stand structure over time. Knowledge of stand development patterns is crucial for effective forest management, especially of southern bottomland hardwood forests. These forests contain more than 70 tree species, many of which have commercial timber and wildlife habitat value. I n this paper, current techniques i n stand development research are reviewed. Em...

We examined the range and the relationships of Marbled Murrelet (Brachyramphus marmoratus) behavior with habitat and landscape characteristics in isolated old-growth and residual forest stands from 2 to 400 ha in California. In large contiguous stands of old-growth forest in parks, we examined relationships of murrelet detections with elevation and topography. In isolated stands we found higher...
