Once a hallmark of the Acadian Forest, old growth has become rare. Under the Interim Old Forest Policy introduced in 1999, over 200,000 ha of forest has been identified on Crown land which conserves a network of old forest restoration opportunities and remnant old growth (>125 years old).
Conservation of old forests on private land is actively encouraged and supported through several initiatives, while research is ongoing to develop tools, monitor progress, and better define old growth in different forest communities.
- Dendrochronologic Confirmation of Old Growth Hemlock Tree Age (October 2021)
- Old Forest Assessment in the Lawlor Lake Area of Guysborough County (May. 2018)
- Selected Nova Scotia old-growth forests: Age, ecology, structure, scoring — A study of four old-growth stands in Nova Scotia was conducted to document the ecological characteristics of these currently rare Acadian forest ecosystems. Stands were selected to represent the two dominant climax forest types, hemlock-red spruce-eastern white pine, and sugar maple-yellow birch-beech.
- Coastal Forest Communities of the Nova Scotian Eastern Shore Ecodistrict — This report examines some of the structures, processes of disturbance and succession, and flora of mature coastal forests in the Eastern Shore Ecodistrict that do not appear to have been shaped by past forest harvesting. This includes summaries of age structure, species composition, deadwood levels, and tree size distribution.
