The long-term monitoring of trees on a permanently marked forest plot gives important information on the structure and composition of a forest, the condition, growth rates and longevity of the species of trees composing that forest, changes in species composition or population size that occur over time and the impacts of environmental change on mature trees and forest ecosystems. Such long-term monitoring is also essential for reliable future assessment and management decisions affecting forest vegetation. Field measurements are recorded once every 5 years during the summer at 10 plots (20 X 20 m2).
Park staff visually evaluate tree health within 20m x 20m forest plots in August each year. Plots are rotated every 5 years (6 plots/year) and monitored according to term Ecological Monitoring and Assessment Network (EMAN) Protocols and Standards. Crown condition, diameter at breast height, and stem defects are used as indicators of tree health to help identify the symptoms of tree and forest decline.
Monitoring of the tree landscape permits detecting changes in habitat availability, forest productivity, forest health, and other ecosystem functions. The park uses permanent sample plots to monitor tree health, growth rate, and forest succession; remote sensing is used for landscape-scale vegetation changes.
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
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.
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.
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.
In celebration of the tremendous diversity of tree species that tell the story of our culture and history, the NCC released in September 2020 a compilation of close to 170 remarkable trees across Canada’s Capital region entitled A Living Legacy: Remarkable Trees of Canada’s Capital.
An interactive map and downloadable book are available for free on the NCC’s website and will allow the public to discover distinctive features of these trees, revealing a story of the beauty of our natural heritage through the rich diversity of species thriving within Canada’s Capital. This compilation features trees according to their commonalities, which can include their physical relationship with the land, the fact that they were a source of food for Indigenous peoples, or for their contribution to the forest industry.
This measure consists of 2 field measurements: Tree Crown Conditions and Stem Defects. These parameters are used to assess overall forest health in the park, as a reduction in crown cover can provide early warning signs of change in forest stand health and succession.
The subalpine zone of Haida Gwaii occurs between an elevation of 600 to 800m. Permanent plots are monitored every 5 years to detect any changes to the structure and composition of the vegetation community on Yatza Mountain. Metrics include: canopy closure, debris classes, tree species, organic matter and percent cover by species. These parameters will then determine if there is a decline in the % cover of vegetation.
