8. Head Start for Hellbenders The hellbenders (a species of large salamander) at the Bronx Zoo
are now approximately seven inches in length and will grow to full size in about five years.
Once they are about two-and-a-half years old, they will be returned to the wild in western New York
State. Hellbender populations are declining due to several factors including over-collection for the pet
trade, disease, pollution, and habitat destruction. Juvenile hellbenders in the wild currently face great
difficulties in reaching adulthood, so the "head start" provided by the reintroduction of the 41 animals
will help boost local populations.. Source: Wildlife Conservation Society, Members News May/June
2011
Describe one potential ecological effect, other than the loss of the hellbender from western New York
State, of the hellbender population continuing to decline.
