Moclips to Grayland

Grays Harbor Co., WA

Site Description:       

This location is an open ocean shoreline consisting of very long stretches of sandy beach with some gravel.  There are very few areas of rock with the exception of the breakwater entering Grays Harbor.  Our data includes species found on the south side of the breakwater at Point Chehalis, which is where most of the gastropod and chiton species were found.  We do not yet include any information from inside the harbor itself.

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

Data is all intertidal unless noted.

This is only a sampling of data from this area and is very incomplete.
