CONTROL OF INTRODUCED SPECIES
The greatest threat to the Galapagos comes from introduced or invasive species. Thesecan damage the lack natural defenses of the native species and can reproduce rapidly, destroying or replacing the native species.
Examples are the Black and Brown Rat, which prey on tortoises and Rice Rat.
Studies
are needed to look at these problems. Control and elimination of
introduced species is a difficult and long-term problem.
