In Ontario, standing trees are reserved to “lifeboat” organisms in harvested forests. I examined epiphytic lichen on residual trees in two natural and managed mixedwood forests. Effects of management intensity, tree species, diameter at breast height (DBH), elevation, and distance to landscape features were investigated on lichen species richness, abundance and community composition on residual trees at three levels of silvicultural intensity. I found that silvicultural intensity had no effect on community composition at both locations, but had some effect on richness or abundance. Tree type (high/low bark pH), DBH, and distance to roads and remnant forest were the most important variables affecting lichen communities, explaining 51% of variance in communities in the first two axes of ordination in Timmins and 43% in Petawawa. Forestry practices in these experimental plots appear to provide the range of habitat variables required to support lichen communities similar to that of an unmanaged forest.
