The "shell stacks", made up of 11 Pacific oyster shells, provide an appropriate substrate for native oyster larvae to deposit themselves. The stacks will be sent to the labs in Olympia to be viewed under a microscope for evidence of native oyster "spat". The remaining half of the stacks will be collected in late May of 2019 or one year from initial deployment. A new set of "shell stacks" will be deployed at that time.
A great way for citizen scientists to help with important research on this once abundant mollusk!
