Giant barrel sponges, Xestospongia muta, are abundant and important components of the southeast Florida reef system, and are frequently injured from anthropogenic and natural disturbances. There is limited information on the capacity of X. muta to recover from injury and on methods to reattach X. muta fragments. In late 2002, hundreds of barrel sponges offshore southeast Florida (Broward County) were accidentally injured during an authorized dredging operation. In early 2003, two to three months post-injury, 93% of 656 assessed injured sponges appeared to be recovering. In 2006, three years post-injury, nearly 90% of 114 monitored sponges continued to show …

The coral reefs of southeast Florida are offshore a highly urbanized area with a population exceeding 5 million people and three major shipping ports with over 6000 ships calling on an annual basis. Reef injury events are common and have been caused by ship groundings and marine construction activities such as channel dredging and cable placement. Restoration activities generally only include the reattachment of dislodged stony corals, removal of rubble, and boulder stabilization. The Florida Department of Environmental Protection has recognized these limited activities and is collaborating with Nova Southeastern University’s Oceanographic Center to study ways to accelerate coral reef …

Replicate scleractinian coral transplants were obtained from the species Meandrina meandrites and Montastrea cavernosa on a natural reef, off Dania Beach, Florida, using a hydraulic drill fitted with a 4 in. (~10 cm) core barrel. The transplants were fixed to Reef Ball™ substrates using an adhesive marine epoxy. Drill holes in the donor corals (core holes) were filled with concrete plugs. Control corals, of comparable size to both donor colonies and transplant corals, were monitored for comparison. Transplant corals, donor corals, and controls on the natural reef were monitored for growth and survivorship. Core holes were monitored for tissue regrowth …

Coral reef damage is unfortunately becoming a common occurrence off southeast Florida, U.S.A. Reattachment of the dislodged scleractinian corals usually initiates damage site restoration. Because mortality of dislodged colonies is typically high and natural recovery in southeast Florida is typically slow, transplantation of additional scleractinian corals into a damaged area has been used to accelerate reef recovery. Donor colonies available for transplantation have been grown in situ, grown in laboratories, and taken from nondamaged reef areas. An alternative source of donor colonies for transplantation into damaged sites is “corals of opportunity,” which we define as scleractinian corals that have been …

In 1997, 271 scleractinian corals growing on a sewer outfall pipe were used in a transplantation study offshore from North Dade County, Florida, USA. Corals were removed from the outfall pipe and transplanted onto concrete armor mat tiles used to cover the pipe. Success (number of corals still attached and alive), mortality (number of dead corals), and growth rates of the transplants were assessed between December 1997 and December 1999. Colony surface area and radius length were measured on scanned photographs to estimate horizontal growth rate. After two years post-transplantation, success rate and overall mortality were 87% and 7.8% respectively. …
