Found 10 records similar to Rangeland health assessments- Elk Island
Rangeland health takes multiple ecosystem components into account and reflects overall ecosystem function. Forest and grassland sites are scored on criteria such as plant community composition, plant community structure, moisture retention, soil erosion and bare ground, weed cover and distribution, and browse species and utilization. Site visits are conducted annually during peak growing season. Protocols are based on those developed by Alberta Environment and Parks, but have been modified for park management applications.
A novel towfish incorporating sidescan and video hardware was used to ground truth echosounder data for the nearshore of Halifax Harbour. The resulting sampling grid extended from the shoreline to a depth of 10 m, including Bedford Basin through the Inner Harbour to the Outer Harbour. Each of these three zones could be distinguished from the others based upon combinations of substrate type, benthic invertebrates, and macrophyte canopy. Bedford Basin had a relative lack of macrophytes and evidence of intense herbivory.
Elk Island National Park conducts an ungulate aerial surveys of the entire park, to census the elk and moose populations. The surveys are carried out in the late fall or winter annually. Park staff also conducts opportunistic counts of elk and moose over the summer and obtain demographic information during elk handling. Elk and moose population is in the same database as bison populations.
Manganese (CAS 7439-96-5) is a metal that is found naturally in air, water, soil and in living systems. Biologically, manganese (Mn) is an essential mineral and is required for the functioning of a number of enzyme families. Very high levels of exposure can result in a clinical and severely debilitating neurological disease known as manganism.
Elk Island National Park annually conducts an aerial census of bison populations of the entire park, as well as opportunistically surveying herd composition. Bison population data is in the same database as elk and moose populations.
The Elk Island National Park annually monitors the change in amphibian occupancy by using call counts, including data collected by citizen scientists.
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.
Elk Island National Park monitors primary productivity to determine the health of forest 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. Forest and grassland primary productivity is in the same database.
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.
