Prince Rupert Harbour Foreshore Habitat Classification

The Port and DFO , joined later by local governments first did an inventory of the harbour habitats and then 

"In 1998, the Steering Committee commissioned a consultant to develop a foreshore classification scheme to classify the intertidal foreshore habitat into a three-class system based on fish habitat value"

The figure left was the result. 

Red areas are considered most sensitive, green the least.

Monitoring a site would make  great School biology project!!

The publication has some useful biology including good physical habitat descriptions. There is an ACCESS database, though the one I have has all the information stripped out of it except the numbers and some general notations like  "eelgrass beds present"
