including Beach she-oak, beefwood,

typically found at sea level, but also
grows inland to 2,600 ft (800 m).
Casuarina is fast-growing, reaching
a height of 65 ft (20 m) in 12 years.
It is drought-tolerant, and can grow
in poor soils because it can fix nitrogen
in nodules on its roots. Its wood is
very hard and is used as a building
material and as firewood. The bark is
widely used in traditional medicines.

years, a mature tree producing 50–80
coconuts a year. The trunk is ringed with

The coconut palm was once the
mainstay of life on Pacific islands.
It provided food, drink, fuel, medicine,
timber, mats, domestic utensils, and
thatching for roofs. It remains an
important subsistence crop on many
Pacific islands today. Its original
habitat was sandy coasts around the
Indo-Malayan region, but it now is
found over a much wider area, assisted
by its natural dispersal mechanism, and
deliberate planting by humans. The
fibrous husk of the coconut fruit is
a flotation aid that enables the seeds
to be carried vast distances by ocean
waves and currents. The coconut palm
cannot develop viable fruits outside of
the tropics and subtropics.
COCONUT FRUIT
The fruit of the Coconut Palm weighs
2¼–4½ lb (1–2 kg). It contains one seed,
which is rich in food reserves and is part
solid (flesh) and part liquid (coconut milk).
