Data Needs
A region-wide AGRRA survey is currently underway
(2006). The new data are for representative reef
habitats and will complement data previously collected
by other site-specific programs largely focused on
MPAs (e.g., local monitoring programs and the MBRS
Synoptic Monitoring Program).
A comprehensive database and meta-analysis are
