Browse surveys occur yearly in July-August and are conducted by park staff. Each plot is composed of nine circular subplots (2-m radius) in a 3 x 3 grid, spaced at 15 m intervals. The number of seedlings (5 – 30 cm) and saplings (30 – 200 cm) of each tree species are counted. Seedling recruitment is correlated with herbivore abundance and provides an efficient method to assess browse pressure in forest ecosystems.
Browse surveys occur yearly in July-August and are conducted by park staff. Each plot is composed of nine circular subplots (2-m radius) in a 3 x 3 grid, spaced at 15 m intervals. Percent cover of priority invasive species, as well as leeks, ferns, grasses and bare ground are assessed visually.
Terra Nova National Park monitors non-native mammal browse pressure on forest plant communities on transects and plots.
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.
This measure includes monitoring of browsing impacts of non-native mammals on populations of the balsam fir populations at 30 randomly selected plots. This measure records percent of browsing on particular firs, and collects multiple metrics, including species diversity, seral stage, etc.
The Elk Island National Park monitors the functions and health of grassland and forest ecosystems that are influenced by herbivory. This includes monitoring vegetation structure, intensity of browsing, primary productivity, soil/site stability, capture and beneficial release of water, functional diversity of plant species.
At high densities, moose can do extensive damage to forests by over browsing - altering forest composition and forest succession. One moose may consume 30 kg of vegetation per day. Fundy National Park conducts aerial censuses of the moose population every 5 years.
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.
Rangeland health takes multiple ecosystem components into account and reflects overall ecosystem function. Forest and grassland sites are scored on criteria such as plant community composition, plant community structure, moisture retention, soil erosion and bare ground, weed cover and distribution, and browse species and utilization. Site visits are conducted annually during peak growing season. Protocols are based on those developed by Alberta Environment and Parks, but have been modified for park management applications.
The Torngat National Park monitors the growth and extent of dwarf birch along elevational transects at 5 locations to understand how shrubs are changing the tundra vegetation in the park and sub-arctic regions. Each transect contains 3 or 4 plots, at lower slope, mid slope, and upper slope. Cover, height, growth increment and browsing of Dwarf Birch, and also soil temperature, are recorded at each plot.
