Summary
Cabbage Tree Basin is located within a national park where pollution in to the basin is minimal. Brief periods of anoxia may occur in the bottom water after floods or with thermal stratification. Hypoxia is periodic or seasonal and has caused mortality of fauna (annual recolonization).

Hypoxia in York River was documented for the first time in the 1970s. It is associated with spring-neap tidal cycle. There has been little to no response in the benthos. Mobile fauna is avoiding the hypoxic areas.
