| Abstract | Boreal macrofungi are an ecologically diverse group of organisms that are threatened by forest management, including harvest-associated reductions in coarse woody debris (CWD) supplies. In this thesis, I compared richness and composition of macrofungal communities in old-growth and post-logged mixedwood stands in boreal northeastern Ontario, including post-logged stands in which downed CWD availability had been experimentally manipulated. Canonical Correspondence Analysis showed a strong distinction between macrofungal communities of unlogged and logged plots, correlated with harvest-related reductions in large-diameter CWD supplies. Rarefaction revealed that macrofungal richness, particularly of saprotrophs, was higher in unlogged compared to logged plots, especially those with experimentally-reduced CWD supplies. These results demonstrate the negative effects of post-harvest decreases in CWD on macrofungal richness and suggest that forest management in Canada may, over time, lead to the harvest-related biodiversity losses of boreal Europe. Management practices that better emulate habitat conditions in old-growth stands, including availability of large-diameter CWD, are discussed. |
