NEW CORAL REEF MANAGEMENT GUIDE PROVIDES STRATEGIES TO CONSERVE WORLD’S
CORAL REEFS
Innovative strategies to conserve the world’s coral reefs are included
in a new guide released today by NOAA, the Australian Great Barrier Reef
Marine Park Authority and The World Conservation Union (IUCN). “A Reef
Manager’s Guide to Coral Bleaching” will provide coral reef managers
with the latest scientific information on the causes of coral bleaching
and new management strategies for responding to this significant threat
to coral reef ecosystems.
“Coral reef managers can play a critical role in helping reefs survive
coral bleaching events,” said retired Navy Vice Adm. Conrad
Lautenbacher, Ph.D., undersecretary of commerce for oceans and
atmosphere and NOAA administrator. “The reef manager’s guide lays out
key actions managers can take before, during and after bleaching events
to help reduce impacts of bleaching and promote resilience of the reef
ecosystem to help it recover from severe bleaching events.”
“The Australian Government is proud to share its expertise with reef
managers worldwide in this highly anticipated publication. Australia is
at the forefront of developing new strategies and tools to respond to
mass bleaching events, minimize impacts and build long-term coral reef
resilience to climate change,” said Andrew Skeat, Great Barrier Reef
Marine Park Authority (GBRMPA) executive director.
The reef manager’s guide, developed in partnership with the U.S.
Environmental Protection Agency, The Nature Conservancy (TNC) and other
organizations, grew out of a 2002 resolution by the U.S. Coral Reef Task
Force calling for development of information and tools for coral reef
managers to address threats from coral bleaching. The reef manager’s
guide can be found online at www.coralreef.noaa.gov and includes
contributions from over 50 experts in coral bleaching and coral reef
management.
“By implementing actions suggested in the guide, coral reef managers are
in a unique position to increase our understanding of the phenomenon of
coral bleaching, to take meaningful action during a bleaching event, and
to develop strategies to support the natural resilience of reefs in the
face of long-term changes in climate,” said David Kennedy, manager of
NOAA’s Coral Reef Conservation Program, which helped produce the guide.
The reef manager’s guide reviews management actions that can help
restore and maintain resilience of coral reef ecosystems. This review
draws on a growing body of research on ways to support the ability of
coral reef ecosystems to survive and recover from bleaching events. The
reef manager’s guide includes specific guidance and case studies on how
to prepare bleaching response plans, assess impacts from bleaching,
engage the public, manage activities that may impact reefs during
bleaching events, identify resilient reef areas, and incorporate
information regarding reef resilience into marine protected area design.
The reef manager’s guide also supports a major goal of the U.S.
Administration’s Climate Change Science Program – to “Understand the
sensitivity and adaptability of different natural and managed ecosystems
and human systems to climate and related global changes” – by providing
managers with options for sustaining and improving ecological systems
and related goods and services, given projected global changes.
The guide identifies three key actions reef managers can take to help
reefs survive and recover from mass bleaching events: (1) increase
observations of reef condition before, during and after bleaching to
increase information and understanding of impacts and areas that may be
especially resistant to bleaching, (2) reduce stressors (e.g.,
pollution, human use) on reefs during severe bleaching events to help
corals survive the event, and (3) design and implement reef management
strategies to support reef recovery and resilience, including reducing
land-based pollution and protecting coral areas that may resist
bleaching and serve as sources of coral larvae for “reseeding” reefs.
Coral bleaching is associated with a variety of stresses including
increased sea surface temperatures. This causes the coral to expel
microscopic algae living in their tissues – algae that provide corals
with food. Losing their algae leaves coral tissues devoid of color and
thus appearing to be bleached. Prolonged coral bleaching (over a week)
can lead to coral death and the subsequent loss of coral reef habitats
and the vital services they provide to coastal communities including
food, jobs and income, as well as protection from the impact of storms.
Mass coral bleaching events have increased in frequency and intensity
since the first recorded event in 1982, resulting in significant coral
mortality and other ecological, social and economic impacts in many reef
ecosystems. In 1997-98, mass bleaching is estimated to have caused over
90 percent coral mortality in many reefs in the Indian and Pacific
oceans, destroying 16 percent of the world’s coral reefs. These
increases in coral bleaching over the past two decades have been
attributed to ocean warming seen in tropical waters around the world. In
2005, Caribbean coral reefs experienced massive coral bleaching followed
by coral disease outbreaks and high levels of coral mortality throughout
the region. This was the most widespread and severe bleaching ever
reported in the Caribbean Sea.
The Great Barrier Reef Marine Park Authority is the principal advisor to
the Australian Government, through the Minister for the Environment and
Heritage, on the care, development and management of the Great Barrier
Reef Marine Park. The Authority works in partnership with other
government agencies, industry, community groups and individuals to help
preserve the social, economic and environmental values of the Great
Barrier Reef.
The World Conservation Union strives to achieve significant improvement
in the conservation of marine biodiversity and sustainable use of
natural resources in marine and coastal ecosystems throughout the world.
In 2007 the National Oceanic and Atmospheric Administration, an agency
of the U.S. Commerce Department, celebrates 200 years of science and
service to the nation. From the establishment of the Survey of the Coast
in 1807 by Thomas Jefferson to the formation of the Weather Bureau and
the Bureau of Commercial Fisheries in the 1870s, much of America's
scientific heritage is rooted in NOAA.
NOAA is dedicated to enhancing economic security and national safety
through the prediction and research of weather and climate-related
events and information service delivery for transportation, and by
providing environmental stewardship of our nation's coastal and marine
resources. Through the emerging Global Earth Observation System of
Systems (GEOSS), NOAA is working with its federal partners, more than 60
countries and the European Commission to develop a global monitoring
network that is as integrated as the planet it observes, predicts and
protects.
