Fig. 7. Dieback in the vegetation of island 1, block C (transects 4 and 5), 7 July 1994 (left), and island 2, block A (transect 8), 7 July 1994. Vegetation covered most of these open areas in 1988; the vegetation dieback took 7-13 years to appear. This problem would probably have been prevented through better island design.
