Ecological integrity of national parks
Access PDF (981 KB)
Ecosystems have ecological integrity when their components, such as native species, biological communities, natural landscapes, and ecological functions, are intact and are likely to persist.Footnote 1 Annually, Parks Canada summarizes the condition (good, fair, poor) and the trend (improving, stable, declining) of ecosystems' ecological integrity in national parks using a series of monitoring measures to track changes in biodiversity and natural processes.

The conditions and trends of ecosystems within national parks are evaluated regularly using a series of monitoring measures which are designed to track changes in biodiversity and natural processes (for example, plant and animal populations and soil properties) or stressors (for example, presence of invasive alien species) within those ecosystems. The condition of an ecosystem is determined by comparing these measures to threshold values, and assigning a score to each measure. The scores are then averaged together to rate the condition of the ecosystem (good, fair or poor). The trend of an ecosystem (improving, stable, declining) reflects a change in condition over a 5 year period (2017-2022).
Condition and trend must always be interpreted with caution. Because the condition represents an average of several monitoring measures, the condition may show no change over time, even if individual measures are improving or declining.
An ecosystem that is rated as good and stable is secure and likely to persist, and no major management actions like ecosystem restoration are required. Fair or declining ecological integrity indicates that the ecosystem is vulnerable and management actions may be required. Poor ecological integrity indicates that the ecosystem is impaired, and significant management actions may be required. Improving ecological integrity results may indicate that restoration actions are working.
Since 2017, the percentage of ecosystems with stable or improving ecological integrity of national parks has declined from 88% to 79%. However, this percentage has not changed significantly between 2021 and 2022.

National parks are interlinked with their surrounding ecosystems and are affected by many of the same pressures on the environment. Declining ecological integrity in ecosystems may be due to stressors. Some of the stressors affecting ecosystems in Canada’s national parks include
- habitat loss and degradation
- reduction of landscape connectivity (for example, building of roads and trails)
- climate change impacts (for example, increasing temperatures) and climate-mediated ecological changes and cumulative effects (for example, diseases and natural disturbances)
- loss of keystone species (for example, wolves or bison)
- pollution and contaminants
- invasive species
Parks Canada implements management actions to conserve and restore species at risk and to improve ecological integrity when issues are identified. Each ecosystem responds differently to stressors and to management actions. It may take many years to make measurable improvements to ecological integrity and to demonstrate the ecological benefits of management actions. Monitoring results demonstrate measurable progress as a result of five conservation projects that are underway in 2022-2023: 4 projects may have contributed to halting declines or maintaining stable conditions, and 1 project to improving ecological integrity. For example, ecological integrity improved in Pacific Rim National Park Reserve where spawning habitat for salmon was enhanced through the Cheewaht Restoration project.

About the indicator
About the indicator
What the indicator measures
The Ecological integrity of national parks indicator summarizes the condition (good, fair, poor) and trend (improving, stable, declining) of ecosystems within 42 national parks.
Why this indicator is important
This indicator provides a measure of the condition of Canada's national parks. National parks help to protect biodiversity, preserve ecosystem services, connect landscapes, and provide a natural solution for climate change by capturing and storing carbon. National parks also help to build knowledge and understanding of ecosystems and connect Canadians with nature.
Parks Canada regularly monitors and assesses the condition of the main ecosystems in national parks (for example, forests, tundra, wetlands or freshwater). Ecosystems are managed to improve or maintain ecological integrity. Management plans systematically address opportunities for improving the ecological integrity of park ecosystems.
Related initiatives
This indicator supports the measurement of progress towards the following 2022 to 2026 Federal Sustainable Development Strategy Goal 15: Life on land – Protect and recover species, conserve Canadian biodiversity.
In addition, the indicator contributes to the Sustainable Development Goals of the 2030 Agenda for Sustainable Development. It is linked to Goal 15: Life on land.
The indicator also contributes towards the Pathway to Canada Target 1 initiative. It is linked to Priority 3: Maximize conservation outcomes. Canada Target 1 was one of the 2020 Biodiversity Goals and Targets for Canada.
It also contributes to the Kunming-Montreal Global Biodiversity Framework. It is linked to Target 3: " Ensure and enable that by 2030 at least 30 per cent of terrestrial and inland water areas, and of marine and coastal areas, especially areas of particular importance for biodiversity and ecosystem functions and services, are effectively conserved and managed through ecologically representative, well-connected and equitably governed systems of protected areas and other effective area-based conservation measures, recognizing indigenous and traditional territories, where applicable, and integrated into wider landscapes, seascapes and the ocean, while ensuring that any sustainable use, where appropriate in such areas, is fully consistent with conservation outcomes, recognizing and respecting the rights of indigenous peoples and local communities, including over their traditional territories."

Data sources and methods
Data sources and methods
Data sources
The indicator summarizes the condition and trend of ecosystems in National Parks. Parks Canada regularly monitors the condition of ecosystems using a set of representative measures. Selected measures in each major park ecosystem are combined and the ecosystem is scored as good, fair or poor. Parks Canada monitoring for ecological integrity formally began in 2008 and is ongoing.
More information
Ecological integrity is reported for major ecosystems in 42 of Canada's national parks. Data are not available for Akami-Uapishkᵁ-KakKasuak-Mealy Mountains National Park Reserve, Nááts'įhch'oh National Park Reserve, Thaidene Nëné National Park Reserve, Qausuittuq National Park, Ukkusiksalik National Park and Rouge National Urban Park.
Between 1 and 4 ecosystems are assessed in each park. Examples of ecosystems include forests, wetlands and glaciers. The selected ecosystems form most of the area of a park and are important to its biological functioning. For each ecosystem, a scientifically sound set of environmental measures is developed, based on appropriateness, representativeness, monitoring needs and cost-effectiveness. Some examples of ecological integrity measures include wildlife population size, estimates of plant productivity, water quality and extent of invasive species. Data for these measures are gathered from a variety of sources, including on-the-ground field sampling, satellite imagery, academic and government partners, and Indigenous knowledge. Measured values are compared to thresholds, such as whether a wildlife population is near desirable size or whether water quality meets a standard threshold. When such thresholds are not available, interim thresholds based on available information of historical variability are used. The frequency of monitoring varies from annually to once a decade, depending on the specific measures.
For this report, data were collected in 2022-2023, then collated and stored in Parks Canada's Information Centre for Ecosystems database to support management and reporting by the end of March 2023.
Data sets for individual measures are published in the Government of Canada Open Data Portal.
Methods
Ecological integrity monitoring is adapted to the ecology of each park. Information is gathered for each selected ecosystem, and a determination is made as to whether the ecosystem is in good, fair or poor condition and whether that condition is improving, declining, or stable. Complete methods information is available in Parks Canada's 2011 Consolidated Guidelines for Ecological Integrity Monitoring in Canada's National Parks, available from the Protected Areas Establishment and Conservation Directorate, Parks Canada.
More information
Ecosystem condition is determined from the monitoring results as follows: each measure is assigned a score based on its condition compared to its threshold (good = 2, fair = 1, poor = 0). If one-third or more of the measures are scored poor, the ecosystem-level indicator is also scored poor. If less than one-third of the measures are scored poor, the average score of the measures (weighted equally) determines the ecosystem score.
The assessment of the overall trend for each ecosystem is based on a change in its overall condition over 5 years, or in the trend of monitoring measures. If the condition of the ecosystem has not changed, it is considered stable unless a strong majority of the monitoring measures shows the same trend.
The national indicator (% of ecosystems maintained or improved) is an overall assessment of the trend of ecological integrity across national parks. It is generated by dividing the number of ecosystems that are stable or improving by the total number of ecosystems monitored.
High quality ecological monitoring provides information that helps prioritize funding for ecological restoration projects to the ecosystems where it was needed most. In 2022-2023, 65 conservation and restoration projects are striving to maintain and improve ecological integrity in Parks Canada administered places.
Recent changes
The monitoring program was enhanced in 2022-2023 by adding and improving ecological integrity measures, particularly measures employing remote sensing. In total, 513 measures were assessed in 2022 as opposed to 505 in 2021. Of the newly assessed measures, 5 employed remote sensing or aerial imagery. An additional 2 remote sensing-based measures were improved. In some cases, improved monitoring provided information that changed our understanding of the condition and trend of an ecosystem. For example, in Mingan Archipelago National Park, 2 additional measures were assessed in the coastal/marine ecosystem that changed the condition of the ecosystem from good to fair in 2022.
Caveats and limitations
The monitoring measures used to determine the condition and trend of ecosystems are chosen to represent the most important elements of the ecosystem and thus provide an indication, rather than a complete assessment, of ecological integrity. Monitoring takes place against a background of natural variability, and because many locations are remote and some measurements are time-consuming or expensive to conduct, the frequency of monitoring may be low. This leads to unavoidable uncertainty in assigning conditions and trends to ecosystems.
Ecosystems are not of equal area or of equal importance in parks; comparisons between systems or between parks must be made with caution.
Some parks have not yet reported results, while others are basing their reporting on incomplete suites of measures that reflect current data availability. Monitoring methods are selected using objective techniques to provide credible overall assessments. Where information is incomplete, expert opinion, literature review, preliminary data and statistical principles are used to support the definition of thresholds.
The equal weighting of measures may not always reflect their relative ecological importance.
The data do not include provincial or other parks or other types of protected areas.
