*** Citing Benefits of No-Take Areas, Scientists Call for New Networks
Marine Reserves ***
There is now compelling scientific evidence that no-take areas -- or
marine reserves -- conserve both biodiversity and fisheries, and could
help replenish depleted fish stocks, according to a consensus statement
signed by 160 marine-science academics from around the world. Released
February 17 at the annual meeting of the American Association for the
Advancement of Science (AAAS), the statement is the culmination of a
three-year, international effort to advance scientific understanding of
"All around the world there are different experiences, but the basic
message is the same: marine reserves work, and they work fast," said
Lubchenco (Oregon State University, USA), a past president of AAAS and a
leader of the three-year effort. "It is no longer a question of whether
to set aside fully protected areas in the ocean, but where to establish
The consensus statement recommends that marine resource managers use
reserves as a "central management tool" for achieving long-term fishery
and conservation benefits. It concludes that networks of reserves,
than isolated single reserves, will be necessary to buffer against
environmental variability and catastrophes.
* Increases in population density, biomass *
The academic effort to develop a better scientific understanding of
reserves grew out of the 1997 AAAS meeting, where scientists reviewed
state of the oceans and identified research priorities. Following that
meeting, several researchers formed a team, based at the National Center
for Ecological Analysis and Synthesis (University of California, Santa
Barbara), to examine the effects of reserves on fish populations.
The team's study of more than 100 reserves from around the world
that after one to two years of protection, these reserves averaged a 91%
increase in population density, 192% increase in biomass, and 23%
in species diversity as compared to reference sites. The consensus
statement also noted that in the few studies that have examined the
effects of reserves on fish populations in adjacent waters, the size and
abundance of exploited species has increased.
"The results are startling and consistent," said Robert Warner of the
University of California, Santa Barbara, a leader of the academic
The consensus statement follows the release last November of another
document from scientists in support of marine reserves. A committee of
the US National Research Council (NRC) released a 150-page report urging
marine resource managers to increase their use of marine reserves as a
supplement to conventional management tools (MPA News 2:5). The report,
Marine Protected Areas: Tools for Sustaining Ocean Ecosystems, assessed
the scientific basis of techniques for locating, designing, and
Megan Dethier (University of Washington, US), who assisted with the
draft of the consensus statement, said the statement's brevity -- three
pages -- reflected its intended purpose. "We wanted to make a
that was short and direct enough to be readily usable by the press,
etc., to help 'spread the word', rather than a complex scientific
that would not be 'picked up' in the way that this one clearly has

* BOX: Conclusions of the Consensus Statement *
- Reserves conserve both fisheries and biodiversity.
- To meet goals for fisheries and biodiversity conservation, reserves
must encompass the diversity of marine habitats.
- Reserves are the best way to protect resident species and provide
heritage protection to important habitats.
- Reserves must be established and operated in the context of other
- Reserves need a dedicated program to monitor and evaluate their
both within and outside their boundaries.
- Reserves provide a critical benchmark for the evaluation of threats
- Networks of reserves will be necessary for long-term fishery and
- Existing scientific information justifies the immediate application
