Canada's National Forest Inventory ground plots are a stratified random sample of select Canadian terrestrial ecozones. Ground plots are remeasured periodically. Data from ground plots include field measurements, compiled attributes and descriptions made at a point inside or adjacent to a photo plot. Ground plot data include individual large-tree and small-tree measurements, shrub tallies, understory vegetation sampling, vegetation cover, stump assessments, woody debris data, surface substrates, site descriptions and soil measurements.
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.
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.
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.
In PEI National Park tree health and growth are monitored in 20 long-term permanent forest monitoring plots. These plots were established in 2006 in mature white spruce forests under the Ecological Monitoring and Assessment Network (EMAN) program. The measure reports on tree species dominance, recruitment, and growth. Field measurements include species, diameter at breast height (DBH), and tree condition.
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).
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 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.
The Acadian forest in a natural state is one of the richest and more diverse temperate forests in the World, however it has been listed as one of six endangered forests in North America and is also the predominant ecosystem within Kouchibouguac National Park. A few key tree species of priority conservation concern have been identified as indicators of forests conditions: white pine (Pinus strobus), eastern hemlock (Tsuga canadensis), and eastern white cedar (Thuya occidentalis). These softwood species merit particular attention due to their rarity relative to historic levels or recent notable declines at the population level. Red maple (Acer rubrum) has also been selected for special interest as a representative of hardwood species in mixed forests.
Forest Total Aboveground Biomass 2015Total aboveground biomass. Individual tree total aboveground biomass is calculated using species-specific equations. In the measured ground plots, aboveground biomass per hectare is calculated by summing the values of all trees within a plot and dividing by the area of the plot. Aboveground biomass may be separated into various biomass components (e.g.
