The significance of the Salish Sea comes into focus when we look at the diversity and abundance of its birds and mammals, some of which are globally, continentally, and nationally important. Of particular importance is the diversity and abundance of species on the Fraser River Delta. There are more species of birds on the delta than any comparable area in Canada, and nearly half of all 550 species of birds reported for British Columbia have been seen on the delta. Despite all that has been learned about marine birds and mammals, large areas of the Salish Sea in Canada have …

An important part of biodiversity monitoring includes assessing the differences in vulnerability across parts of an ecosystem. Hypoxia is one of the big three climate- related stressors causing biodiversity loss in the oceans. As the ocean warms, its capacity to hold oxygen becomes reduced. At the same time, concurrent shifts in circulation result in changes to how oxygen gets transported from the surface (where oxygen dissolves into the ocean) to the seafloor and from offshore to inshore areas. When a habitat experiences a substantial drop in oxygen, below the point needed to sustain everyday life, animals respond by migrating away, …
