The approach used for assessing the management plan consists of several steps. The directions outlined in the plan are initially reviewed to ensure that they are in accordance with Parks Canada's mandate and policies. The development and activities involved in presentation of the site are examined in order to bring to light any sources of stress. Impacts identified are then characterized in terms of duration (temporary or permanent impact) and extent (no impact, little impact, mitigatable, non-mitigatable, unknown). General measures aimed at lessening the negative impacts anticipated are then determined.
