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.Google Map

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 tripDue
to the nature of the data, this list will not be rated for frequency of
occurrence.
