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).
The raster maps depict a suite of forest attributes in 2001* and 2011 at 250 m by 250 m spatial resolution. The maps were produced using the k nearest neighbours method applied to MODIS imagery and trained from National Forest Inventory photo plot data. For detailed information about map production methods please refer to Beaudoin et al. (2018) "Tracking forest attributes across Canada between 2001 and 2011 using the k nearest neighbours mapping approach applied to MODIS imagery."
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 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.
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.
High-resolution binary wetland map for Canada (2001-2016). Wetland map for the forested ecosystems of Canada focused on current conditions. The binary wetland data included in this product is national in scope (entirety of forested ecosystem) and represents the wall to wall characterization for 2001-2016 (see Wulder et al. 2018).
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.
Canada's National Forest Inventory (NFI) sampling program is designed to support reporting on forests at the national scale. On the other hand, continuous maps of forest attributes are required to support strategic analyses of regional policy and management issues. We have therefore produced maps covering 4.03 × 106 km2 of inventoried forest area for the 2001 base year using standardised observations from the NFI photo plots (PP) as reference data. We used the k nearest neighbours (kNN) method with 26 geospatial data layers including MODIS spectral data and climatic and topographic variables to produce maps of 127 forest attributes at a 250 × 250 m resolution.
