The objectives of this study were to determine the species composition and density of natural conifer regeneration following selective logging in southeast Alaska.
Therefore, we quantified the density and size of new cohort spruce and hemlock and current seedling bank in 17 selectively logged stands. All stands were in mixed...
Lichen sensitivity to air quality has been recognized in Europe
for over 125 years: recently Federal agencies in this country have
begun using lichens as air quality bioindicators. This study presents
the results of three different approaches to air quality biomonitoring
using lichens: (1) a lichen community analysis, (2) an...
Silviculture systems that involve commercial thinning may provide higher quality wildlife habitat than traditional clearcut systems, yet such systems have not been vigorously tested. This prospective study examined forest floor animal abundance and habitat relationships under three different silviculture conditions: clearcuts, commercial thins, and uncuts. Eighteen stands, six per treatment,...
