The report details the proof of concept testing (POCT) of the Canadian Biodiversity Index (CBI), a tool designed to provide a consistent mechanism for assessing biodiversity status and trends across Canada. Testing was conducted on two ecounits: Netley-Libau Marsh in Manitoba and Banks Island in the Northwest Territories. The POCT confirmed the CBI's potential as a national index, particularly its flexible 0-100 normalized scale that allows for the comparison of diverse indicators. However, the testing revealed significant challenges regarding the availability and quality of historical indicator data and the subjectivity involved in setting 'Desired Future States' (DFS) and scoring ranges. Key recommendations include renaming the 'Landscape and Global Factors' theme to 'External Influences', adopting an average of theme scores rather than a 'weakest-link' approach for overall ecounit scoring, and implementing a finer scoring scale (rounding to the nearest 5) to better detect trends.

The report details a project in Sachs Harbour, Banks Island, where Inuvialuit observations confirm significant climate warming, including later autumn freeze-ups, earlier spring thaws, and melting permafrost. The project combined participatory workshops and scientific interviews to produce a broadcast-quality video and seven journal articles, aiming to raise public awareness and influence decision-makers. Findings highlight the value of traditional knowledge in providing detailed historical narratives and identifying environmental linkages that complement Western science.
