Found 10 records similar to Advanced regeneration of balsam fir - Gros Morne

Federal

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.

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.

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.

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.

We measured the foliage area, weight and number of buds on young and mature balsam fir and white spruce trees. With these measurements total amounts of foliage per tree and per unit area of forest land can be calculated. These estimates can be used to determine the absolute numbers of insects feeding on these trees, numbers that are important in understanding patterns and fluctuations of population abundance. We also discovered that spruce budworm larvae occur preferentially in buds arranged in clusters.

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.

The Ontario Forest Biomonitoring Network (OFBN) monitors the health of mixed hardwood forests across southern and central Ontario. The data set includes: * Individual Tree Data: Decline Index and other measurements of visual stress symptoms of each tree within 111 plots * Decline Index: The Decline Index is a weighted average of tree stress symptoms (percent dead branches, percent slight or strong chlorosis (pale green-yellow leaves) and percent undersized leaves). Averaged for hardwood trees found within each of the 111 plots in each year. * Invasive Plant Species Presence Data * Salamander Data: numbers of individuals of salamander and other animal species in 14 plots * Tree Regeneration Data: monitors numbers of tree seedlings/saplings in 102 plots * Woody Debris Data: amount of woody debris on ground in 102 plots

The park assesses expected ranges for each land cover type: successional stages by stand type, area regenerating after natural disturbance (e.g., fire), mature forest, non-forest, wetlands, and waterbodies.

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.
