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.)
