'Super reefs' fend off climate change, study says
Date:4/23/2009

NEW YORK (April 23, 2009) The Wildlife Conservation Society announced today a study showing that some coral reefs off East Africa are unusually resilient to climate change due to improved fisheries management and a combination of geophysical factors. WCS announced the results of the study at the International Coral Reef Initiative (ICRI), which is meeting this week in Phuket, Thailand.

The study, published in the online journal Aquatic Conservation: Marine and Freshwater Ecosystems, provides additional evidence that globally important "super reefs" exist in the triangle from Northern Madagascar across to northern Mozambique to southern Kenya and, thus, should be a high priority for future conservation action.

Authors of the study include Tim McClanahan and Nyawira Muthiga of the Wildlife Conservation Society, Joseph Maina of the Coral Reef Conservation Project, Albogast Kamukuru of the University of Dar es Salaam's Department of Fisheries Science and Aquaculture, and Saleh A.S. Yahna of the University of Dar es Salaam's Institute of Marine Sciences and Stockholm University's Department of Zoology.

The study found that Tanzania's corals recovered rapidly from the 1998 bleaching event that had wiped out up to 45 percent of the region's corals. Along with monitoring Tanzania's reefs, WCS helps coral conservation in this region through training of park staff in protected areas.

The authors attribute the recovery of Tanzania's coral reefs due in part to direct management measures, including closures to commercial fishing. Areas with fishery closures contained an abundance of fish that feed on algae that can otherwise smother corals, while the few sites without any specific management measures remain degraded; one site had experienced a population explosion of sea urchinspests that feeds on corals.

The findings also showed that the structure of the reefs played a major factor in their resiliency. Tanzania's reefs are particularly complex and experience unusual variations in current and water temperature. These factors allow for greater survivorship of a higher diversity of coral species, including those that can quickly re-colonize after bleaching.

"Northern Tanzania's reefs have exhibited considerable resilience and in some cases improvements in reef conditions despite heavy pressure from climate change impacts and overfishing," noted Wildlife Conservation Society scientist Dr. Tim McClanahan, the study's lead author. "This gives cause for considerably more optimism that developing countries, such as Tanzania, can effectively manage their reefs in the face of climate change."

The authors suggest that reefs in Tanzania and elsewhere that exhibit similar environmental conditions have the ability to recover from large-scale climatic and human disturbances. They may, therefore, be a priority for conservation under predicted climate change scenarios where many reefs are expected to suffer further degradation.

On a broader scale, the Wildlife Conservation Society is actively conserving nearly 90 percent of the world's tropical coral reef species in priority seascapes in Belize, Indonesia, Papua New Guinea, Fiji, Kenya and Madagascar.
