Overbrowsing of balsam fir saplings by introduced moose can lead to stand conversion to non-forest. The park measures the browse rates of fir saplings in mature forest stands, which will indicate whether non-browsed advanced regeneration is sufficent to allow stand replacement following disturbance. Browsed and unbrowsed saplings are being enumerated in 1x20 m strip transects, 6 of which are sampled at each of 15 randomnly selected sites in mature forests throughout the 3 ecoregions in GMNP (90 strip transects total). Sampling will occur every 2 years during the months of July to September.
The park measures forest regeneration and succession on 15 EMAN plots in deciduous and mixed forests on Beausoleil Island. The surveys report on the number, height class and survival of tree seedlings and saplings.
TINP evaluates seedling and sapling density within 5 subplots of the 20m x 20m EMAN forest plots in August each year. Plots are rotated every 5 years (6 plots/year) and are monitored according to term Ecological Monitoring and Assessment Network (EMAN) Protocols and Standards.
Non-Forest cover polygons interpreted from aerial imagery on a 10 year cycle for the province of New Brunswick. The attributes contain information that describes the non-forest characteristics for that polygon area including agriculture, settlement, utility corridors, etc.
Intensive moose browsing appears to have led to a large reduction in woody plant abundance and diversity in Gros Morne National Park mature forests.This measure assess the biodiversity of native shrubs and tree saplings in the understory of mature balsam fir forest stands. Stems are being enumerated by species in 1x20 m strip transects, 6 of which are sampled at each of 15 sites in forests throughout the 3 ecoregions in GMNP (90 strip transects total). Sampling is carried out every second year, during the months of July to September.
What? Forest Health plots in the Boreal and Acadian land regions are being monitored in Cape Breton Highlands National Park to determine if any historical changes are occurring. When? Monitoring frequency for this program occurs on a five year cycle within the Acadian and Boreal Forest regions; sampling typically occurs in July or August.
The Alberta Regeneration Information System (ARIS) requires a unique identifier assigned to a cutblock to enable tracking within ARIS. This number is generated from a point roughly derived from the centre of the cutblock. The number is a concatenation of the point's legal description plus a grid cell number. The format is MRRTTTSSGG where M - Meridian, RR - Range, TTT - Township, SS - Section, GG - grid cell.
See the accuracy and usage WARNING in the Identification: Supplemental Information and Data Quality: Source Information sections. Landscape Units are spatially identified areas of land and/or water used for long-term planning of resource management activities. Landscape units are important for designing strategies and objectives to maintain landscape level biodiversity and for managing other forest resources. Landscape units are also used to initiate landscape unit plans, which provide direction on biodiversity, old growth forest retention, wildlife habitat maintenance and timber harvesting.
Forest canopy or over-story species composition provides useful information on forest tree species present at the stand and landscape level. Much of PEI National Park’s forest areas were cleared for settlement and agriculture prior to park establishment and have regenerated with early successional softwood species. Forest types, stand area (ha), percent canopy crown coverage and the proportion (percent) of tree species present within National Park forested areas are determined by remote sensing experts every 10 years, where the proportion of PEI National Parks forest ecosystem that is comprised of softwood species is calculated. The observed percent softwood forested area within PEI National Park is compared against the expected percent of softwood composition generated using available soil information to conjecture original forest types and softwood composition by applying Nova Scotia’s Eco-site Classification.
