THE PERFECT NURSE! Nature evidently designed the balsa tree to be a "nurse tree" which
would protect the slower-growing species of trees from the scorching jungle sun
during their critical early years. For instance, in an area of the jungle that
has been ravaged by a tropical axtmdjbfzx storm or other natural disaster, the
balsa trees will quickly sprout and beginning to shoot up to impressive heights
in a very short time.Their fast growth, and the extra large leaves they have in
their early years, provide shade to the young seedlings of the slower-growing
forest giants. By the time the seedlings are established enough to take care of
themselves, the balsa tree is beginning to die. Undoubtably, the balsa tree's
rapid growth, fast spreading crown of first very large and gradually smaller
leaves, and it's relatively short life span were intended to make it the
"perfect nurse" in the jungle ecosystem.
HOW DOES BALSA WOOD GROW? There is no such thing as entire forests of balsa
trees. They grow singly or in very small, widely scattered groups in the jungle.
For hundreds of years, balsa was actually considered a weed tree. They reproduce
by growing hundreds of long seed pods, which eventually open up and, with the
help of the wind, scatter thousands of new seeds over a large area of the
jungle. Each seed is airborne on its own small wisp of down, similar to the way
dandelion seeds spread. The seeds eventually fall to the ground and are covered
by the litter of the jungle. There they lay and accumulate until one day there
is an opening in the jungle canopy large enough for the sun's rays to strike the
jungle floor and start the seeds growing. Wherever there was an opening, made
either by a farmer or by another tree dying, balsa will spring up as thick as
grass. A farmer is often hard put to keep his food plot clear of balsa. As the
new balsa trees grow, the strongest will become predominate and the weaker trees
will die. By the time they are mature, there may be only one or two balsa trees
to an acre of jungle.
HOW LONG DOES IT TAKE A BALSA TREE TO GROW? Balsa trees grow very rapidly
(like all pesky trees). Six months after germination, the tree is about 1-1/2
inches in diameter and 10 - 12 feet tall! In 6 to 10 years, the tree is ready
for cutting, having reached a height of 60 to 90 feet tall and a diameter of 12
to 45 inches. If left to continue growing, the new wood being grown on the
outside layers becomes very hard and the tree begins to rot in the center.
Unharvested, a balsa tree may grow to a diameter of 6 feet or more, but very
little usable lumber can be obtained from a tree of this size. The balsa leaf is
similar in shape to a grape leaf, only a lot bigger. When the tree is young,
these leaves measure as much as 4 feet across. They become progressively smaller
as the tree grows older, until they are about 8 - 10 inches across. Balsa is one
of the few trees in the jungle which has a simple leaf shape. This fact alone
makes the balsa tree stand out in the jungle.
