FIG. 16. Pattern of distribution of mangroves on Magnetic Island, off Townsville, Queensland, based on air photographs and personal
observation. I n comparison with Figs. 6 and 8, a zone of Ceriops tagal is interposed between the landward fringe and the bruguiera
forest. This zone of Ceriops is interrupted by bare areas. The rainfall is around 1 500 mm, and seasonal, but seepage water from
the mountain keeps the streams perennial. This type of distribution is typical for areas of intermediate rainfall ; it gives way to
the pattern shown in Fig. 11 when evaporation and transpiration come t o be excessive. Explanation of transect as in Figs. 6 and 8.
