PROJECT FUNDING GENEROUSLY PROVIDED BY:  
The South Pender Island shoreline is largely bedrock and resistant to erosion. There are a 
few sand and shell pocket beaches that are very important recreationally. The northwest 
end of South Pender Island is protected by North Pender Island to the west and north, and 
partially protected by Saturna Island to the northeast.  The southeast end of South Pender 
Island is partially exposed to south-easterly storm winds and waves. 
South Pender’s only areas of mudflat is located in an embayment on the southeast end of 
the island.  There is a small, very protected saltmarsh area just to the northeast of the 
protected channel between North and South Pender Islands, partially surrounded 
by a soft sediment spit. There are several areas of archaeological and/or cultural 
importance along the shoreline.  All of these areas are sensitive to nearby 
recreational activities and general human disturbance.
