Burrard Inlet to Howe Sound, BC

Site Description:       

Burrard Inlet is bordered by Vancouver, BC.  Although surrounded by residential and industrial growth, there are also many parks with beaches.  The beaches are a mix of sand and cobble, with a few consisting of rock outcroppings.  Being in a very urban area, these beaches are not pristine habitats and do not support a wide diversity of mollusks. Most of our data is subtidal.  Dredging of parts of the Inlet have occurred in the past and some of the data results from species found in the dredging material brought ashore.
Howe Sound is immediately adjacent to the north.  There are several islands in the sound and many of the beaches are rocky.  This area is far less inhabited and the habitat is more pristine and less accessible.  Our data for this area is also primarily subtidal.

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.
Intertidal - I
Subtidal - S         (lack of a symbol indicates it is unknown if observed intertidally or subtidally)
