Operational Framework for Use of Conservation Allowances: chapter 6


Allowance Design Elements

The following allowance design elements reflect international best practices for conservation allowances and are to be used as the starting point in the development of a conservation allowance. The design elements should be applied case-by-case based on the legislative framework under which the allowance is being applied, potential environmental impacts of the proposed land- or resource-use activity and desired socio-ecological outcomes as well as consideration of Canada’s unique conservation goals and needs.

The allowance design elements are:

Equivalency: Conservation allowance projects should compensate for adverse impacts by protecting, enhancing or restoring equivalent ecological function at another site.

Ecological functions are processes (such as nutrient cycling or seed dispersal) that are carried out or enabled by an ecosystem and that are necessary for the self-maintenance of that ecosystem. Analysis of equivalency should consider both quality (provision of similar or dissimilar ecological function) and quantity of ecological functions in the context of conservation priorities. Provision of similar habitat types or ecosystem functions provide a starting point for the design of a conservation allowance.

In some cases, a conservation allowance may be designed to provide greater than equivalent ecological functions in order to account for identified risks, such as that the allowance will not be fully successful. Whatever the unit of measurement, the ratio of the conservation allowance habitat area to impacted habitat should be greater than 1:1 in all cases, and normally at least 2:1. There will be instances where much higher ratios are appropriate; for example, experience in other jurisdictions in North America shows use of ratios ranging from 3:1 to 40:1. The choice of ratio for each allowance will be case-specific, based on an assessment of a number of factors (e.g. impact type, severity and duration, site characteristics, existing regional mitigation ratios, uncertainties).

Additionality: Conservation allowances should provide ecological protection beyond what would be provided under a business-as-usual scenario."Additionality" ensures that the new ecological feature(s) provided by the conservation allowance replace what has been lost through land or resource development, providing an overall balance between what is lost and what is gained. The following criteria should be assessed in order to establish whether an allowance is additional:
