Taller, dominant coconut palms, averaging 45 ft in height and 14
in. in diameter at 5 ft above ground, fringed the central lagoon side
.of the island to a depth of about 800 ft. Several brush species composed a dense understory of a uniform 20 ft height that extended over
the remainder of the island, broken only on the east and west ends by
taller clumps of the broadleaf Pisonia averaging 50 ft in height and
24 in. in diameter at the base.
Figure 2.2 shows the Iccation of the
principal Uncle stand components and their relation to ground zero.
Excluding the somewhat heavier tropical undergrowth found on
Uncle Island, the Pisonia clumps bore a marked resemblance to an American beech forest by the deliquescent branching and leaf size. Also
superficial examination showed the root systems to be similar. With or
the-ground study it became increasingly apparent that this similarity
to the beech forest would meke the Pisonia portions of the stands the
most useful for verification of breakages vrediction system developed.
Palm, on the other hand, a monocotyledon, is unlike either the
coniferous or broadleaf trees (both dicotyledons) that comprise the
pulk of the earth's sizable temperate vegetation. The stem of paim doe
