Pacific Rim National Park

Vancouver Island, BC

Site Description:       

Pacific Rim National Park is along the west coast of Vancouver Island facing the Pacific Ocean.  It stretches between Tofino and Nitinat Lake and includes the islands of Barkley Sound.  Our information includes the area between Tofino and Bamfield, which is at the southern edge of Barkley Sound.  We also include the subtidal region of the Sound.  The coastline is a typical mix of both sandy and rocky beaches.   Barkley Sound has been the site of commercial shellfish culture and therefore also includes several introduced species.

Species List:

     Following is a list of mollusk species observed at this location by members and associates of the club.  This is by no means a complete list of the species which may occur at this site.  Revisions and additions to the data are made as we acquire new information.   When a site contains more than one very distinctive type of habitat or if multiple sites were included in a single location, then a species list for each is included.
    We indicate frequency of occurrence based on our observations.  This is an indicator of how likely it is that you may be able to find this species yourself and is not a formal population survey.  

     Frequency Code:  (Based on the assumption that you are looking in the appropriate location where the species
                                          likes to live - on rocks, in sand, etc.  
Some populations fluctuate seasonally.  Ours are based
                                          on the spring/summer seasons.
)
     [4] - Rare - very difficult to find, maybe only a couple found after repeated visits to the site
     [3] - Uncommon - difficult to find, may not see on every trip but dedicated searching may turn up a few
     [2] - Common - easy to find, should locate a number of them on any given day
     [1] - Abundant - very easy to find, large numbers should be seen on every trip


Due to the nature of the data, this list will not be rated for frequency of occurrence.  It is also an incomplete list for common species.
