Fresno Chaffee Zoo Helps Island Foxes

What are those island foxes whispering?

They are spreading the word that the Fresno Chaffee Zoo Wildlife Conservation Fund has provided island foxes with a special end of the year 2022 grant.

$2,400 will help fund Canine Distemper Virus and 

Rabies vaccinations

Canine distemper virus is typically fatal to island foxes. To protect them, a minimum number of 100 island foxes are vaccinated each year on each island.

Because the vaccine that is safe for island foxes only provides protection for 10–11 months, island foxes need to be vaccinated every year.

Vaccination takes place during annual health checks.

Catalina Island has an increased threat of CDV for island foxes. Approximately, 350 island foxes are vaccinated each year on Catalina. FIF funds Catalina shots 2022

This year FIF has the goal to provide vaccine for: 

• 350 Catalina Island foxes
• 100 foxes on Santa Cruz
• 100 foxes on Santa Rosa
• 100 foxes on San Miguel

With support from the Fresno Chaffee Zoo, Riverbanks Zoo, and private donors like you, we'll vaccinate 650 island foxes in 2023.

We only need to raise another $2,000 to protect 650 island foxes

 

Zoos Helping Island Foxes

Sometimes you have to look behind the scenes to see the important role that zoos play in wildlife conservation. The island fox has several important zoo friends.

Fresno's Chaffee Zoo

Fresno's Chaffee Zoo has been a vital partner in island fox recovery and health for 16 years. It started with a few zoo keepers committed to helping island foxes and a donation for a radio-tracking collar. 

When the zoo established their Wildlife Conservation Fund, Friends of the Island Fox was a 2014 grant recipient. Over the years, the FCZ Wildlife Conservation Fund has funded not only radio collars, but vaccinations, equipment for safe capture of island foxes, important evaluation of island fox blood samples for evidence of disease and other critical health measures.

In January of 2022, the FCZ Wildlife Conservation Fund provided a special one-time grant that funded the refurbishment of 15 radio collars for Santa Cruz Island foxes. These collars were all placed on island foxes over the last month. The grant also helped fund vital testing for disease among island foxes.

Friends of the Island Fox just received our FCZWCF grant of $3,200 for 2022. This funding will go toward health monitoring and/or vaccinations for island foxes.

 

Santa Barbara Zoo

The Santa Barbara Zoo was the first to come to the aid of endangered island foxes and they participate in the Island Fox Conservation Working Group. Keepers and veterinary staff helped develop the care and feeding protocols for island foxes in captive breeding facilities from 2001–2006. The zoo has provided a home for a few island foxes and was the first to successfully breed island foxes in captivity. Today, all of the island foxes living in mainland zoos are rescued wild individuals that do not have the skills to survive in the wild. 

Lewis and Clark (above) are brothers who were abandoned by their parents in the midst of drought on San Clemente Island. Today these two island foxes play an important role for their wild relatives. Because they live in a controlled environment with ready access to veterinary care, they are health advocates for other island foxes. They provided samples to the island fox microbiome research study. 

Early in the pandemic it was discovered that Covid-19 could be passed to canines. As the pandemic grew there was concern for island foxes in the wild. Could biologists handle island foxes for health checks as they had in the past? Might island visitors pass Covid-19 to island foxes?

Island foxes are very susceptible to introduced diseases. Many vaccinations for dogs are not safe for island foxes. In the controlled environment of the Santa Barbara Zoo, Lewis and Clark were vaccinated against Covid-19. They had no ill side-effects. Zoo veterinarians monitor whether the vaccine continues to protect the two foxes. If necessary we know island foxes can be safely vaccinated for Covid-19.
