Found 10 records similar to Browse Pressure - Terra Nova
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 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.
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.
Terra Nova National Park monitors annual decay rate by measuring decomposition of tongue depressors buried within randomly selected Balsam Fir and Black Spruce plots.
2007 Health Canada summary chart on labelling requirements for cosmetics in pressurized containers
This index measures the relative intensity of the Aleutian Low pressure system of the north Pacific (December through March). It is calculated as the mean area (km²) with sea level pressure <= 100.5 kPa and expressed as an anomaly from the 1950-1997 mean. A positive index value reflects a relatively strong or intense Aleutian Low. The index was completely regenerated using a new method in 2015.
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.
DISCLAIMER - Current ATCO Gas data is available up to 2019 as-builts only. This dataset represents all rural low-pressure pipelines (less than 700 kPa) in Alberta under the jurisdiction of the Gas Distribution Act which include Gas Co-ops, First Nations, Counties, Private Systems, Apex Utilities, and ATCO Gas and is based on annual submissions of as-builts to Rural Utilities, Alberta Alberta Affordability and Utilities. The attributes of the pipelines contain the contact info, plus the status of the pipelines as being either Active or Abandoned. Rural Utilities assumes no responsibility as to the accuracy or completeness of these plans, Individual distributors must be contacted for actual locations of their pipelines.
