Terra Nova National Park monitors non-native mammal browse pressure on forest plant communities on transects and plots.
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 measure includes monitoring of browsing impacts of non-native mammals on populations of the balsam fir populations at 30 randomly selected plots. This measure records percent of browsing on particular firs, and collects multiple metrics, including species diversity, seral stage, etc.
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.
Gwaii Haanas has partnered with ECCC to monitor a set of permanent plots mapping colony structure and burrow occupancy rate by excavating samples of burrows of Ancient Murrelet and Cassin’s Auklet. The data are used to determine if the breeding population areas are changing at specific key nesting colonies and if the change signifies an increasing or decreasing population trend. An estimated 1.5 million seabirds breed colonially on the 200+ islands, islets and rocks of Haida Gwaii, including globally and nationally significant proportions of 5 seabird species. A significant threat to breeding seabirds is predation by non-native mammals, notably raccoons and rats.
Kootenay 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.
Yoho 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.
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.
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.
