Miami Wreck Trek Connectivity Project
During 2010 DERM submitted a grant request to the Florida Department of Fish and Wildlife. The grant is to place approximately 750 tons of lime rock boulders at two artificial reef sites in Miami-Dade County. 325 tons of boulders are proposed in Biscayne Bay at the Artificial Reef Site in Coconut Grove (15' depth) and 325 tons of boulders planned as a "connectivity" project offshore at the Belcher Barge Wreck Trek Site (70' depth) off Key Biscayne. The goal of the project is to enhance both inshore, juvenile habitat and offshore habitat for adult species by using the boulders to "connect" the wrecks.
The grant has been approved and the first two connections between the Belcher Barge and the Belzona II and between the Belcher Barge and the Park/Schurger Barges have been complete as of July 2012.
The Survey Data:
The spread sheet showing data from all surveys can be downloaded here. (in Excel format).
The following table shows a brief summary of some of the data.
The three small tugs consistently show significantly fewer species and lower abundance levels than the two large barge sites.
With the exception of the Parker/Schurger site the other four sites show fewer species in December than in August.
