The problem of invasive rodents in santa catalina island and santa cruz island

Today, 1,500 roam the Island in one of the greatest success stories of any federally Endangered Species. The Santa Catalina Island fox is a descendant of the gray fox, but is approximately 25 percent smaller than its ancestor, weighing only four to six pounds. The Catalina variety is just about a foot tall and measures 23 to 32 inches from nose to tail.

Its fur is made up of varying shades of gray, brownish-red and black, with white patches under the face, chest and belly and on the legs. Catalina Island foxes, known to science as Urocyon littoralis catalinae, are opportunistic omnivores that eat animals, insects and plants.

Their diet changes with the seasons and the availability of different food.

Some of their favorite meals are toyon, prickly pear cactus fruits, Catalina cherry and Catalina Manzanita as well as Jerusalem crickets, rodents, lizards and small birds. It can be found all across the island in a variety of habitats. Unlike most members of the Canidae family, which also includes dogs and wolves, Channel Island foxes have curved semi-retractable claws that allow them to climb trees and securely scramble between braches, similar to cats.

Foxes generally stay within their territories, which they mark with urine and scat, leaving only when required to find food.

Foxes mate for life. Mating occurs in January and February.

Pups are born after a 50- to 53-day gestation period in March or April. An average litter consists of two pups, but Island foxes can have as many as five if the mother is well fed and healthy. Pups are born blind and remain in the den for their first month.

Both parents care for the litter, providing food and protection for six to eight months. Foxes typically live eight to 10 years, but can live as long as 13 in the wild. Six of the eight Channel Islands have their own endemic subspecies of Island Fox: Each differs in coloration, size, muzzle shape, tail length, dietary preferences and genetics.

Origins on the Island: Gray foxes likely floated out to the Northern Channel Islands on rafts of debris as far back as 16,000 years ago, when ocean levels were lower than they are today. Radiocarbon dating has placed foxes on Catalina as far back as 6,000 years ago. Since rebounding from an outbreak of canine distemper in 1999, the Catalina Island fox population is closely monitored through an annual trapping survey — the latest of which was conducted this fall — and weekly telemetry flights.

Some of these foxes have been vaccinated against canine distemper and rabies, while the majority remains unvaccinated, acting as disease sentinels, alerting biologists to any new diseases that may arrive on the Island.

The collared foxes are tracked by airplane. If a mortality signal is detected, biologists immediately recover the carcass and ship it to a lab to determine the cause of death. These laborious efforts ensure that this unique, emblematic animal remains on Catalina Island for many generations to come.
