(a) Mean density per 200 m2 of A. percula (open bars) counted along four replicate 50×4 m visual transects at each of six different locations. Reefs are grouped into those with and without vegetated islands. Filled bars, anemones. (b) Mean density per 400 m2 of rainforest leaves at four different distances (beach, reef crest, 0.5 and 1 km) from the two islands (Kimbe Island (filled bar) and Tuare Island (open bar)). On two other reefs without islands (May Reef, South Bay Reef), no leaves were recorded. Error bars are standard errors.
