Elk Island National Park monitors primary productivity to determine the health of grassland vegetation throughout the park. This measure relies on remotely-sensed multispectral satellite imagery, specifically, the Landsat Shortwave Infrared (SWIR2) and Near Infrared (NIR) bands. Analysis is performed roughly every five years, using images from mid-July. Grassland and Forest primary productivity is in the same database.

Elk Island National Park uses land cover classification to determine spatial changes of forest vegetation throughout the park. This measure relies on a supervised classification of remotely-sensed multispectral satellite imagery (Landsat). Analysis is performed roughly every five years, using images from mid-July.

The Elk Island National Park monitors the functions and health of grassland and forest ecosystems that are influenced by herbivory. This includes monitoring vegetation structure, intensity of browsing, primary productivity, soil/site stability, capture and beneficial release of water, functional diversity of plant species.

Forest birds in Elk Island National Park are surveyed annually along 24 established routes, with 4 stations along each route. The stations are spaced 400-600 meters apart. Sampling occurs between late May and early July. Forest bird surveys have occurred in the Park since 1985, but current methods, using audio recording devices, have been used only since 2009.

From the point of view of ecological integrity and the responsibility of the park to protect and maintain a biotic community naturally associated with the ecoregion, we are primarily interested in the extent of two land cover classes, the old-growth forest, which should not decrease in the park, and the artificially cleared areas or the anthropogenic footprint, which should not increase. This program measures the extent of old-growth forest and tracks changes in the land cover class (measured in 30x30m grid cells) to the baseline year (1990). We use land cover datasets derived from remotely-sensed satellite imagery of the park to capture forest-stand replacement events, which in our case are due to construction-related clearing or natural stand-replacing events (e.g. windthrow from storms).

Elk Island National Park uses the Area Burned Condition Class (ABCC) method to evaluate the ecological impact of fire on the landscape and the success of utilizing fire to maintain a mosaic of vegetative composition and structure for healthier populations of native species. Area burned is derived from Landsat imagery, and is updated as needed. This measure uses the same database as grassland area burned.

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.
