4.7 Ecological Integrity in the Transportation Corridor
The transportation corridor is the most significant internal threat to the ecological integrity of the parks. The highway and railway are located in scarce valley bottom habitat and influence the movement of wildlife and water. Chapter 8 describes this threat in detail and sets out objectives and actions to address it.
4.8 Indicators of Ecological Integrity
To measure progress towards the goal of maintaining or restoring ecological integrity, Parks Canada will use indicators of ecological integrity that represent components of the ecosystem that are either sensitive to change, or that reflect overall ecosystem health. By comparing the health of an indicator to a target or desired level, progress in achieving the parks’ goals for ecological integrity can be assessed. Individual indicators are determined based on a number of measures.
Indicators and targets, and the associated research and monitoring, will also help Mount Revelstoke National Park and Glacier National Park fulfill their obligations to assess and report on the state of ecological integrity within the parks.
The ecological integrity indicators that have been adopted in this plan have been chosen in association with the other mountain national parks. Together, these parks constitute the Montane Cordillera Bioregion within Parks Canada national ecological integrity monitoring program.
Some of the actions in this section relate directly to establishing targets or comparing the status of indicators with their targets. Some actions are well underway and others are more of a challenge.
In the future, additional indicators will be added (e.g., atmosphere and climate, geology and landforms) to establish a suite of indicators of ecological integrity to be used in bio-regional monitoring, consistent with other national parks in the bio-region. Additional measures will assess different spatial and temporal scales. Parks Canada’s goal will be to maintain existing levels of ecological integrity and to work towards improvements, where specific threats exist and restoration of ecological integrity is possible.
