This is a backpack electrofishing based survey that enumerates all species caught a random selection of sites within a given watershed. Cascade, Panther and Spray watersheds were sampled in the fall of 2015, 2016 and 2017 respectively. The purpose is to repeat these surveys every 10 years to quantify changes to the distribution of native and non-native fishes.

Lakes and ponds are a significant aquatic feature in Waterton Lakes National Park. Due to the extreme topography, many of these water bodies were fishless prior to historic stocking. Historic stocking practices have highly altered fish
communities. In many locations the presence of nonnative fish is putting native fish populations in jeopardy.

Atlantic salmon are an ecologically and culturally important species in healthy aquatic systems of western Newfoundland. This measure determines the status and trend, over a 10 year period, of Atlantic salmon returning to spawn in three rivers in Gros Morne - Western Brook, Trout River and Deer Arm Brook. Secondarily, it will detect invasive anadromous species. A salmonid counting fence is rotated through the 3 rivers.

This map, created in 2002 using ArcGIS, describes the number of animal and plant species that are at risk in Alberta. 'Species at risk' is a term used by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) that includes the following categories of plants and animals:Extirpated species - no longer in the wild in Canada.Endangered species - species facing imminent extirpation or extinction.Threatened species - likely to become an endangered species if nothing is done to reverse factors leading to its extirpation or extinction.Species of special concern - species that may become threatened or endangered due to biological characteristics or identified threats.

Brook trout are top predators in aquatic ecosystems at Kejimkujik that integrate the effects of stressors throughout the aquatic trophic structure. They are sensitive to a variety of stressors, including acidification, changes in water quality, climate change, fishing pressure, exotic species introductions, trophic structure alterations, land use change, and watershed fragmentation. The monitoring program tracks Brook trout population status, as assessed by relative abundance and trout condition at two watersheds in Kejimkujik. Volunteer anglers record morphometric and catch per unit effort data during the months of April, May and June for 3 years in a row every 5 years.

Non-native plants have invaded most low-elevation habitats and physically disturbed sites in Waterton Lakes National Park (WLNP). Parks Canada devotes substantial resources annually to efforts to control or eradicate the most invasive and persistent non-native plants. A Non-native Plant Condition Monitoring protocol was developed to detect changes in the abundance and distribution of non-native plant species across vulnerable regions of WLNP, and to gain an understanding of the severities and differences in impacts that non-native plants have on native plant communities. Relative abundance (I.e.

Invasive plants can reduce biodiversity and compromise ecosystem function by out-competing native species, altering nutrient cycling, destabilizing soils and causing erosion, among other impacts. Prevention of colonization by weedy invaders is achieved through rapid restoration and reduced disturbance, both providing an advantage to native species to resist future invasions by non-natives. Jasper National Park monitors non-native species and carry outs control measures where non-native species have the potential to threaten vulnerable habitats and ecosystem in the Park.

This dataset covers electrofishing efforts in 11 streams or rivers in Forillon National Park since 2008. The abundance, size structure and condition of the fish in a brook trout population are sensitive to changes in the environment, specifically those caused by the presence of an invasive alien species, pollution or climate change, making this measure a good indicator of the health of the aquatic ecosystem. Fish, mainly brook trout, are harvested using electrofishing equipment in a closed 100-square-metre stretch of stream. Three fishing sessions, or passages, are carried out.

Non-native mammal species are monitored annually in areas critical for the protection important seabird islands. Remote cameras are deployed for 15-days to annually detect any changes to the mammal community at key sites. Non-native species pose the greatest ecological threat in Gwaii Haanas. Deer dramatically alter the vegetation and rats, racoons and squirrels impact native species both directly (predation) and indirectly (competition).
