Between 2023 and 2024, the trends of 20 ecosystems changed. Nine (9) showed positive changes with 5 moving from stable or declining to improving trends, and 4 moving from declining to stable trends. In contrast, 11 ecosystems experienced negative changes with 8 moving from being stable or improving to declining trends, and 3 moving from improving to stable trends.

Since 2016, the percentage of ecosystems with stable or improving ecological integrity has declined from 89.6% to 79.7%, with the lowest being 78.6% in 2022. However, this percentage has remained relatively stable since 2020 with no change between 2023 and 2024.

The conditions and trends of ecosystems within national parks are evaluated regularly using a series of monitoring measures that 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 measures over a 5-year period (from 2019 to 2024). As measures may change over the 5-year period without crossing threshold values it is possible to have an improving or declining trend without a change in ecosystem condition.

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. Ecosystems whose condition is fair or has a declining trend 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.

Key results

In 2024,

• All ecosystem types, except for glaciers, had stable or improving ecological integrity, ranging from 64% to 100%
• The ecosystem types with the most declining conditions included glaciers (100%), coastal/marine (36%), forests (22%) and tundra (22%)
• The ecological integrity of grasslands and shrublands were stable or improving in all parks

Declining ecological integrity in ecosystems may be due to stressors within the site or within the surrounding ecosystems. 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 including increased wildfire size and severity)
• changes in abundance of keystone species (for example, wolves or bison)
• pollution and contaminants
• invasive species
• the reduction or exclusion of fire as a natural process in fire adapted ecosystems both from historic fire suppression and lack of Indigenous cultural fire, leading to increased risk of wildfires

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.

In 2024, 27 conservation and restoration projects took place in 17 national parks. These projects aimed to improve the ecological integrity by restoring the natural ecosystems. In Elk Island National Park, the reintroduction of fire and targeted removal of invasive alien species contributed to restoring the ecological integrity of grassland ecosystems. Controlled fires and managing invasive plants improved food quality for grazing animals and brought back natural patterns of fire and grazing. As a result, 670 hectares of grassland are under active restoration, making native prairie ecosystems stronger and more resilient.

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 35 national parks, 7 national park reserves and 1 national urban park.

Why this indicator is important

This indicator provides a measure of the condition of Canada's national parks, national park reserves and a national urban park. These parks help to protect biodiversity, preserve ecosystem services, connect landscapes, and provide a natural solution for climate change by capturing and storing carbon. They 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 these ecosystems.

Related initiatives

This indicator supports the measurement of progress towards Goal 15 of the 2022 to 2026 Federal Sustainable Development Strategy: 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.

It also is used for reporting on Target 3 of Canada’s 2030 Nature Strategy: "Protected and conserved areas (30x30)." This target is related to the Kunming-Montreal Global Biodiversity Framework 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."

Related indicators

Canada's conserved areas indicators report the amount and proportion of Canada's terrestrial and marine area that is conserved.

The Global trends in conserved areas indicator compares Canada's protected area to a peer group of countries.

The Extent of Canada's wetlands indicator measures the extent of Canadian wetlands, and provides a baseline from which change can be measured.

Data sources and methods

Data sources

The indicator summarizes the condition and trend of ecosystems in the majority of 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 began formally monitoring ecological integrity in 2008 and is ongoing.

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 Park Canada’s Protected Areas Establishment and Conservation Directorate.

Recent changes

The monitoring program was enhanced in 2024 by adding and improving ecological integrity measures. In total, 525 measures were assessed in 2024 as opposed to 523 in 2023. In 2024, Rouge Urban Park assessed 2 new measures in its forest ecosystem: bird communities and key tree species health.

In some cases, improved monitoring provided information that changed our understanding of the condition and trend of an ecosystem. For example, in Point Pelee National Park, the wetland ecosystem changed from fair in 2023 to good in 2024 because higher resolution imagery was used to monitor open water and edge habitat in the marsh. This imagery increased the number of small patches of open water observed in the ecosystem.

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 national 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 parks, other parks or other types of protected areas.
