I list here 2 introduced species of snakes to the islands. This number
is not based on breeding populations, nor on actual types of snakes present,
but more as a guess of potential threat snakes. These snakes I would list
as the Brown Tree Snake (Boiga irregularis)
and the Boa Constrictor (Boa constrictor). The
boa constrictor is a threat because of its use as a pet that could potentially
be released. The brown tree snake is a species that is known to cause
major damage in other places - most notably, Guam.
Guam, like Hawaii, has no native snake species. Its bird fauna had adapted
to life without slithering predators. Then, in 1950's the US military
probably accidentally introduced this species on cargo from other Pacific
islands. The result today is a massive invasion of these snakes. Densities
are around 13,000 snakes per square mile. Very few native bird species
exist. Reports from friends that have worked in the field, tell me that
there are no bird sounds when you walk through the bush. Its a sad story,
and that's what makes the Brown Tree Snake Hawaii's number one most unwanted
species.
Just under a dozen snakes have been collected in the last two decades,
having fallen out of the the wheel-wells of incoming planes. Its a number
high enough to make Hawaiian officials very scared. If a snake like this
got to the islands it could do the same thing as it did on Guam. Besides
the birds, humans should be wary as the snake is dangerously venomous.
