On the island there are no services- no cars, no bikes, just
25 campsites (which do have potable water and pit toilets! Luxurious!) and a
handful of facilities for the rangers who live there. The Channel Islands are home to an endangered
species of fox found nowhere else- the Channel Island fox. Each island has its
own unique subspecies, and I was really hoping to catch a glimpse of the Santa
Cruz Island fox. I didn’t have to look far- these creatures have figured out
that campers = food, and are like squirrels, running around campsites, jumping
on picnic tables, and running away with any unattended food items. Heavy-duty
lock boxes are provided at each picnic table, and when the foxes climbed on the
table with us standing a few feet away during the middle of the day, we
understood why.
The foxes are an endangered species success story. Descendants
of mainland gray foxes, they have evolved on the islands for about 10,000 years
with no natural predators and are quite small- the size of large house cats.
Bald eagles have historically lived on the islands, though they only eat fish,
seabirds, and carcasses; not live foxes. Farming came to the islands, bringing with it
DDT which began to wipe out bald eagles and non-native animals which were a
food source for golden eagles, which could move in when their bald eagle
competitors were declining. Golden eagles were also large enough that they
easily preyed on the Island Foxes. By the late 1990’s there were only 80 foxes
left on Santa Cruz Island. The National Park service and US Fish and Wildlife
began an aggressive, multi-pronged approach to save the foxes.
Some of the remaining individuals were brought into a
captive breeding program. The golden eagles were moved off the island and the
native bald eagles were brought back in. Livestock were shipped off and the
feral pigs were wiped out. Efforts continue to remove invasive plant species,
such as fennel, which outcompete natives.
Foxes are now reproducing unassisted (as evidenced by the 3 baby foxes
we saw! So cute!!) and are roaming the island. Of course, their interactions
with campers (and human food) are not natural, but the park service makes sure
to educate everyone who comes over on the ferry and make sure they are aware of
the problem. It was amazing to see so many foxes!
