Relative abundance of clam and crab species in ...

This table has been extracted from the "State of the Park Report for the Ecological Integrity of Stanley Park," produced by the Stanley Park Ecology Society in 2010.

The information in this table was gathered in order to determine if the varnish clam or purple mahogany-clam (Nuttallie obscurata) and the European green crab (Carcinus maenas) have become established in Stanley Park (131). No European green crabs were found at the study sites (131).

This data expresses what percentage of clams or crabs each species makes of the total population of clams or crabs in each study region; thus, each study region may have a total population percentage of 200%--100% for crabs, and 100% for clams.
