The wetlands (Part 1)

Formerly Salt Creek,the remaining environment is sadly nothing similar to the one I recall.Gone are the Mangroves,the crab burrows and fish nursery.The water is now toxic but supports algae growth,which in turn supports a variety of aquatic life,attracting local and migratory waders.Mullet can survive in this environment and these fish are preyed on by cormorants, pelicans and herons.

The surviving saline flora will disappear as stage 3 progresses,work has already begun on the housing estate,this will lead to an influx of introduced weeds such as the African Daisy (dead vegetation in foreground of above photo ),soon displacing native flora.

Ecology of a beach

The beach at South Point,Lincoln Cove is a typical example of the areas beaches,protected at both end by rock groynes which halt the erosion by prevailing winds,it is composed partly by introduced sand and natural processes.Above the high water mark various coastal vegetation flourishes,helping to prevent erosion by their spreading root systems.
