Program Info

In 2003, 2008 and 2013, LRD staff mapped and assessed oyster reefs found in the NW and SW Forks of the Loxahatchee River. The 2003 and 2008 data sets characterize and quantify the baseline conditions, including temporal variability, prior to modification of freshwater inflows resulting from CERP and the Northwest Fort Restoration Plan. The 2013 data set reassesses the oyster habitat condition for change over time and followed a substantial Northwest Fork oyster restoration project in 2011. Note that only counts of oysters within three size bins (<5cm, 5-10cm and >10cm) are available in the 2003 data set, not individual specimen measurements.
acreage (acres), density (oysters/m^2), shell height (counts of individuals <5cm, 5-10cm and >10cm in 2003 data set, individual measurements to nearest half cm for 2008 and 2013 data sets), percent live (% within 0.25m^2)
Sample locations with coordinates outside of a managed area, but within 5m of a managed area boundary were considered within the managed area (and their corresponding points are shown within the managed area boundary on all SEACAR maps).
Assessment of 2007-2008 Loxahatchee River Oyster Mapping and Recruitment Final Report
Reefs larger than 1m^2 and containing more than five live oysters were mapped using a Trimble Pro XR. 1-5 randomly placed 0.25m^2 quads (# dependent on reef size) were sampled. Density and shell height (measured from umbo to opposite margin) of live and articulated dead oysters were measured.
