Once again, Channel Islands National Park is in the news because of
its efforts to eradicate that which it considers problematic. This
time, park officials are attempting to seek approval for their plan to
kill 2,000 non-native black rats on the island.
In November, 2000, a pound of the poison brodifacoum was laced in
50 pounds of kibble, then dropped from a helicopter on Middle Anacapa.
Of the islands 700 acres, this initial poisoning affected only
10 acres on a portion of the island that is not open to public visits.
Future drops are planned for the fall of 2001, and again in 2002, but
the National Park Service must first have the approval of the
Environmental Protection Agency. Controversy remains over whether the
poison will also affect other animals on the island, as well as if
nonnative species should, indeed, be eradicated.
