Summary
Given the importance of oysters in estuarine ecosystems, it is the goal of the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM NERR) to understand the status of local oyster populations and the reef habitats they build, and to track changes over time. The purpose of this living document is to record and share oyster monitoring protocols as they develop. Methods were developed for use on intertidal reefs of Crassostrea virginica using the following body of work as general guidance: Baggett (2014), Dix (2010), Volety & Savarese (2001). Original applications of these methods are documented in a report summarizing a pilot oyster monitoring project within the GTM NERR conducted from 2014-2016 (available upon request).
Parameters
number and sizes of all live oysters, mussels and clams (mm), numbers and ID of barnacles, crabs and gastropods present, carapace width (mm), rugosity (chain length - linear length), percent cover (point intercept method), reef height (m), oyster clump density (#/m^2)

Method
Sampling of randomly-selected reefs using randomly positioned quadrats along a transect. Quadrats positioned randomly along a transect line on each reef. Percent cover assessed using 1m x 1m quadrats and point-intercept method; samples for oyster measurements and faunal census taken using a 25cm x 25cm quadrat and excavated to 15cm depth.
Discontinuity
Data from 2018 were added because they were collected in association with the Historical Oyster Body Size Project; 2020 data were collected in association with another project
