The richness of benthic macro-invertebrate species is used to monitor the overall health of stream ecosystems in Gwaii Haanas. Any shifts in community composition, initially detected as an increase or decrease in species richness, can be the result of nutrient levels, atmospheric pollutants, or...

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...

The EPT index measures the proportion of freshwater organisms belonging to the taxa Ephemeroptera, Plecoptera, Trichoptera (or EPT for short). These species are considered to be highly sensitive to pollution and are a measure of good environmental conditions. Any significant declines to these...

Water Quality is measured annually in both streams and lakes in Gwaii Haanas. Many water quality parameters are collected and they can be grouped into three categories: (1) Physical (e.g. temperature, depth); (2) Chemical (e.g. pH, nutrients) and (3) Biological (chlorophyll a). Water quality is...

Yoho National Park samples 28 randomly selected potential amphibian breeding sites (out of possible 66) to determine presence or absence of amphibian species. Each of the 28 sites is visited 3 times every 2 years and all detected species are recorded.

Whitebark pine is considered a “keystone species” in the mountain national parks, as it plays several important ecological roles where it exists in subalpine environments. Its survival has been threatened by the combined effects of fire suppression, climate change, mountain pine beetle outbreaks...

The following standard is used to evaluate Parks Canada Agency’s goal to manage wildland fire and conduct prescribed fire activities to restore and maintain the ecological integrity of park lands. A 20% natural fire cycle is the set percentage that allows fire to play a role as a natural...

This measure tracks changes in presence and absence of three amphibian species at 43 potential breeding sites. Each site is visited twice (where possible), to estimate and account for detection probability the Western Toad (Bufo boreas), Columbia Spotted Frog (Rana luteiventris), and Long-toed...
