Marine Reserve Areas Work Well
- A 2002 review of 112 independent empirical measurements of 80 different reserves concluded that "average values of all biological measures were strikingly higher inside marine reserves compared to reference sites (either the same site before the reserve was created or equivalent sites outside the reserve). Relative to reference sites, population densities were 91% higher, biomass was 192% higher, and average organism size and diversity were 20-30% higher in reserves." Furthermore, the review found that these values were "independent of reserve size, indicating that even small reserves can produce high values."
