Dear Coral-Listers,

Just a note to let you know the article:

Jameson SC, Tupper MH, Ridley J (2002) The three screen doors: can
"protected" areas be effective? Marine Pollution Bulletin

is now out in the November issue of the Marine Pollution Bulletin.

If you would like a reprint or PDF version via email please let me know.


The great majority of marine protected areas (MPAs) fail to meet their
management objectives. So MPAs can be effective conservation tools, we
recommend two paradigm shifts, the first related to how they are located
and the second related to how they are managed. MPAs are unlikely to be
effective if they are located in areas that are subject to numerous, and
often uncontrollable, external stressors from atmospheric, terrestrial,
and oceanic sources, all of which can degrade the environment and
compromise protection. MPA effectiveness is also limited by low
institutional and community capacity for management and inappropriate
size with respect to ecological needs. In particular, the check list
approach to management does not ensure that key threats are dealt with,
or that management expenditures provide a quantifiable return. We
recommend a business planning approach to MPA management, in which
managers focus on the viability of the management system, i.e. the
ability of the MPA to provide ecological goods and services to its
users over the long term.

Best regards,
