Found 10 records similar to Deer Browse - Summer Woody - Thousand Islands
Browse surveys occur in early spring 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. Browse pressure of woody species 30 cm – 2 m tall is assessed visually. 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.
Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows two maps for the annual total precipitation. Annual precipitation is defined as the sum of rainfall and the assumed water equivalent of snowfall for a given year. A specific gravity of 0.1 for freshly fallen snow is used, which means that ten inches (25.4 cm) of freshly fallen snow is assumed to be equal to one inch (2.54 cm) of rain. The mean annual total precipitation and snowfall maps on this plate are primarily based on thirty-year data during the period 1921 to 1950 inclusive.
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.
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.
Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate with three maps that show the mean annual number of days with measurable precipitation, the mean annual number of days with measurable snowfall, and the variability of annual precipitation. A day with sufficient measurable precipitation (a precipitation day) is considered as a day on which the recorded rainfall amounts to one one-hundredth of an inch (0.0254 cm) or more, or the snowfall measured is one-tenth of an inch (0.254 cm) or more. At any one location the annual precipitation may vary considerably from one year to the next. This variability of annual precipitation is expressed in terms of the coefficient of variation.
Several measures that characterise downed woody debris are recorded along three, 45.14 m transects associated with long-term Ecological Monitoring and Assessment Network (EMAN) forest plots. Several measures are recorded including the diameter of the DWD at point of contact, tree species, decomposition class, and several others.
This database contains the data set described in Andrieux B. et al. (in preparation) about carbon stocks in Quebec's spruce feathermoss forests. Carbon density in different reservoirs of the ecosystem is available at the plot scale (n = 72): living aboveground biomass, coarse woody debris, organic soil horizon, mineral soil (top 15 cm), mineral soil (15-35 cm) and illuvial (B) horizon (top 15 cm). Ancillary biophysical data includes geographic locations, topographic surveys, composition of the moss mat, time since fire, and soil properties (carbon content, bulk density, forest floor depth, pH, texture and amorphous metals).
