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.
