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.)
