Deadwood abundance in recently harvested and old Nova Scotia hardwood forests
Deadwood (dead standing tree (snag), woody debris (WD; downed deadwood), buried wood and stump abundance) was estimated in northern hardwood forests of Nova Scotia dominated by Acer saccharum, Betula alleghaniensis, Fagus grandifolia, Betula papyrifera and Acer rubum. Three strata were examined (1) old forests, (2) forests clearcut 1–2 years before measurement and (3) forests clearcut 8 years before measurement. Deadwood stocks in old and clearcut Nova Scotia hardwood forests were low compared with deadwood stocks reported for similar southern and inland forests. Deadwood was 62–88 per cent WD, amounting to 11–37 Mg ha–1. No snags >30-cm diameter at breast height were encountered, with snags containing just 23 per cent of total deadwood biomass in old forests. Harvesting left no snags standing, but immediately generated a flush of WD. Small pieces (
