Transcription
grassland only a foot or so high over level soil. This type
of scrub on the west side of the abrupt outcrops (in the few
areas it appears in) and in the north and south is more
irregular and without such a dense twig and leaf canopy. Even
so it is gnarled and close growing and often reaches a height of
15 ft. in individual trees but the great majority do not go
above 12 ft. or less in height. The lower dense scrubs of this
type all along the coast are much subject to salt spray burning
during hurricanes and even in high winds as enormous rollers
break from deep water on to a shallow ledge (dry or almost so at
low tide) and spray and spume are thrown to tremendous heights
and carried inland on the wind. Birds do not seem to favor this
vegetation to any large extent. A few Gerygones and Myiagra
being found. Halcyon is probably the commonest bird in the area.
Accipiter spends considerable time playing on the updraft of wind
in the area and feeds on numbers of rats which inhabit the rocks
or cliff faces. Except where coconuts appear in the lee of the
outcrops honey feeders are entirely absent. Numbers of Pachyaphata
appear at one or two places in the lee of the outcrops.
CULTIVATION TYPES
These are the usual rotation types of secondary growth in
garden but have far more stages than usual because of longer
rotations practiced seldom less than 10 years and often longer.
All are very much less dense and luxuriant than usual for this
type of secondary growth and for the first 2 to 3 years are little
more than rather barren grasslands with a few weed shrubs in most
areas. In one or two of the more fertile spots lantana grows but
does not usually appear till well on in the rotation about the 7th
or 8th year. Zosterops and Lichmera are about the only birds
