![]() In the Nova Scotia Uplands ecoregion where sugar maple occurs, later successional VTs include TH1 (Sugar maple / Hay-scented fern) and TH2 (Sugar maple / New York fern – Northern beech fern).Įcological Features: Across eastern Nova Scotia, this closed canopy hardwood forest is distributed as a large patch spanning several hundred hectares. Early successional stages can be by-passed if, at the time of disturbance, advanced red maple and yellow birch regeneration is retained. In eastern Nova Scotia, early successional VTs include IH4 (Trembling aspen / Wild raisin / Bunchberry), IH6 (White birch – Red maple / Sarsaparilla – Bracken) and IH7 (Red maple / Hay-scented fern – Wood sorrel). Disturbance agents include wind, ice damage, insects/disease and harvesting. Stands are predominantly even-aged but can develop uneven-aged canopy structures with time. Successional Dynamics: TH8 is a mid to late successional climatic climax hardwood VT dominated by red maple and yellow birch. This VT is widespread and common throughout the Acadian Forest Region. However, it can be found scattered throughout Nova Scotia on similar sites. It is found primarily in eastern Nova Scotia on upper and middle slopes of gentle terrain and on the drumlins of the Eastern Interior, Mulgrave Plateau and Bras d'Or Lowlands ecodistricts. The bryophyte later is discontinuous and species-poor, especially where the forest floor is characterized by leaf litter and/or where the softwood component is low.Įnvironmental Setting: TH8 is mainly associated with fresh to fresh-moist, nutrient medium to rich soils of glacial origin. ![]() Other common plants include bunchberry, wood sorrel and gold thread. ![]() The herb layer has extensive fern cover including wood ferns, hay-scented fern and New York fern. Other shrubs include striped maple, mountain maple and fly-honeysuckle. In the shrub layer these roles reverse with softwood regeneration dominant (especially balsam fir). Vegetation: Red maple and yellow birch are the dominant overstory trees, but most stands also have a minor softwood component comprised of balsam fir, red spruce and/or white spruce. In the eastern mainland, TH8 is a late successional VT elsewhere in Nova Scotia it is considered mid-successional. The variant (TH8a) defines stands where white ash is present in the overstory, a reflection of increased moisture and/or fertility. Sugar maples are noticeably absent or only present as a minor structural component. TH8 - Red maple – Yellow birch / Striped mapleĪcer rubrum – Betula alleghaniensis /Acer pensylvanicumĬoncept: This mid to late successional Vegetation Type (VT) has an overstory dominated by red maple and yellow birch.
