Habitat & Species
Aquatic habitat and species in the Peace sub-basin are experiencing moderate change. Less healthy fish and mass fish die-offs have been observed by Indigenous communities in the upper and lower Peace. Populations of some fish species are observed to be in decline or locally extirpated, although healthy populations persist in large rivers, protected areas and the Rocky Mountain foothills. Scientific studies suggest that riparian areas are largely intact in the lower Peace and tributaries, and are highly degraded in the agricultural areas of the upper Peace and Smoky-Wapiti watersheds.
The following table summarizes the availability of information for each Habitat and Species indicator.

1 Qualifiers for the availability of local and Indigenous Knowledge observations in publicly available sources: Limited = 1-2 observations; Some = 3-4 observations; Many = 5 or more observations
2 Qualifiers for the availability of science data in publicly available sources: Low = Individual studies or locations; Many = Network of monitoring stations across the basin
Declines in fish populations and health condition have been observed by Indigenous communities and scientists in some areas in the Peace sub-basin. Healthy populations persist in large rivers, protected areas and the Rocky Mountain foothills.
Wetlands & Riparian Forests
There is considerable wetland cover in the Peace sub-basin, but information on changes over time in wetlands in the sub-basin is limited.
Wetland Mapping for the Peace Sub-basin as part of a published Canadian Wetland Inventory that still requires validation. 
The highest riparian disturbance was in upper Peace and the Smoky-Wapiti sub-basin, where agricultural land development has degraded riparian forests. Agricultural land has been concentrated in the riparian zones of these two sub-basins.
