Despite the variable quality of the data , the results from this review suggest that nearly any marine habitat can benefit from the implementation of a reserve . Success of a marine reserve , however , will always be judged against the expectations for that reserve , and so we must keep in mind the goals of a reserve in its design , management , and evaluation . INTRODUCTION Marine reserves (also called marine protected areas , no-take zones , marine sanctuaries , etc ) have recently become a major focus in...
