Monteverde : Ecology and Conservation of a Tropical Cloud Forest

Figure 9.5. (top) Gap 237, in the taller forest in the ravine bottom of the Cerros Centinelas study watershed. A 1.5-m-
DBH (diameter at breast height) Ficus crossiuscula uprooted and in turn uprooted a 40-cm-DBH Guarea tuisana. The
dotted lines show gap boundaries. Isoclines of photosynthetic photon flux density are (from the bottom) 0.1, 0.25, 0.5
and 0.75 of that above the forest canopy. In the upper profile, the azimuth from left to right is 0°. In the lower profile
the azimuth from left to right is 270°. Figure 9.6. (above) Gap 214, in the elfin forest along the boundary ridgecrest of
the Cerros Centinelas study watershed. A Clusia sp. (45- and 55-cm-thick trunks) fell apart over a five-year period. The
gap indicated by dotted lines is the last episode. In the upper profile, the azimuth from left to right is 90°. In the lower
profile the azimuth from left to right is 180°. Isoclines of photosynthetic photon flux density as in Figure 9.5.
