Data description
The percent of images classified as barrens showed a general increase
through time for all sites (Fig. 2). There were distinct differences in
the percent barrens at each site, with these differences being
maintained through time. The Governor Island reserve (all transects
pooled at each time step) always had a lower observed percentage of
barrens when compared to any of the reference sites, with less than one
percent of images being classified as barrens habitat in any year. For
the reference sites, Cape Lodi consistently had the highest percent
barrens through time, followed by Trap Reef and Butlers Point.
