Freshwater fishes are some of the most imperiled taxa worldwide as evident by the number of threatened and endangered species. For example, the Committee on the Status of Endangered Wildlife (COSEWIC) in Canada has listed bull trout (BLTR, Saskatchewan - Nelson Rivers populations) as “threatened” and westslope cutthroat trout (WSCT, Saskatchewan - Nelson Rivers
populations) have been listed as threatened under the Species at Risk Act (SARA Schedule 1). Parks Canada developed an occupancy
monitoring protocol to understand the relative distribution of both native and nonnative species, and to track these distributions over time. This occupancy survey program is being used to track replacement and/or displacement of our native species and could potentially track the efficacy of restoration
projects.

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.

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.

What? Juvenile salmonid densities are being monitored in various rivers within Cape Breton Highlands National Park using electrofishing surveys. When? Monitoring frequency occurs annually in the late summer/early fall once water temperatures have dropped below thermal stress thresholds for salmonids (<20oC) and water levels have started to rise above summer lows.

Banff National Park monitors invasive alien plants with the use of permanent, random stratified, belt transects established in the alpine. Occurrence frequency of all detected non-native species is recorded along a belt transect.

Both native and non-native fish inhabit many lakes and ponds across Jasper National Park. Prior to stocking practices in the past, many lakes in Jasper National Park did not have fish or had a low diversity fish assemblage. These past stocking practices have altered fish communities today. Introduced non-native fish may outcompete some native fish populations and the stocking of historical natural fishless lakes may affect their food webs.

Banff National Park monitors invasive alien plants with the use of permanent, random stratified, transects established in each of the three management zones, in close proximity to vectors of spread (highways, trails, campgrounds, etc.). Percent cover of all detected non-native species is recorded along each transect using the line intercept method.

We surveyed the presence of four native amphibian species in wetlands throughout the eastern section of Banff National Park. This dataset represents detection or non-detection for each of the four species. We performed auditory and visual surveys of 60 pre-determined breeding sites . We surveyed each site two times during a sampling period between mid-April and the end of May.

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.
