Book excerpt: Little is known about habitat requirements of lichens and evidence suggests that they may be negatively impacted by forestry. The purpose of this thesis is to: (1) determine if harvesting and thinning affect certain forest structural features; (2) determine if harvesting and thinning affect diversity or abundance of selected epiphytic lichen species; (3) determine habitat and forest structural features important in explaining diversity and abundance of some lichen species; and (4) examine the use of lichens as bio-indicators of forest structure. Structural forest features and abundance on trees of 34 species of arboreal lichens were measured and compared among thirty stands in three maturity classes in central Nova Scotia including natural forests with no timber management and harvested and thinned and harvested forests. Significant differences in forest structural features were found between natural and managed forests. Structural features found to be most correlated with lichens are tree age, crown closure and remnant trees. Natural forests had significantly greater total lichen abundance, number of lichen species and lichen diversity than managed forests. Forest management practices can be changed to improve habitat for lichens and increase biological diversity in managed forests.
