Vaccinating Island Foxes is an Annual Need

 

Companion dogs are vaccinated against canine distemper annually and so are island foxes.

This Since June biologists have been out in the field across the Channel Islands vaccinating island foxes against rabies and canine distemper virus. The vaccine being administered across 4 islands was provided by donors like you. Who's helping fund vaccinations?

Did you know?

  • Canine distemper virus (CDV) is a dog version of the measles virus. It's highly contagious like measles, entering the body through the respiratory system. New research suggests that measles from humans was transferred to dogs 500 years ago during the Spanish colonization of South America. 
 
  • Distemper spreads rapidly through wildlife populations. CDV infects dogs, foxes, wolves, and coyotes, but also raccoons, ferrets, and skunks. The virus is especially deadly to African and Asian species of big cats (lions, leopards, tigers, etc.)
 

  • CDV is so lethal to island foxes, they can't withstand the vaccine created for domestic dogs. Island foxes are treated with a dead-virus vaccine that is made in small batches, by one company, and is used by a short list of endangered species: black-footed ferret, giant panda, Iberian lynx, African wild dog, African lion, all tiger species, and other large cats.
 

  •  A new study from Penn State University has found evidence that canine distemper virus is influencing grey wolf evolution. A gene mutation, CPD103, creates a black coat in grey wolves. This mutation also makes the lungs less susceptible to the introduction of disease. Black-colored grey wolves are less likely to become infected with CDV. In areas where CDV occurs in high rates, entire wolf populations become darker in color, because the lighter colored individuals are lost to the disease. Read more about this study.
 
Health efforts for rare wildlife go hand-in-hand with research. FIF raises funds to vaccinate island foxes and to investigate important health research.

Vaccinating Island Foxes Takes a Community

 $15,322 of vaccine is headed into the field to protect island foxes!


Donors like you made this possible!

Why do island foxes need to be vaccinated annually?

Canine distemper virus (CDV) caused a catastrophic decline of Santa Catalina Island foxes 26 years ago. Evolving in isolation on their islands, island foxes haven't developed immunity to typical canine diseases. To protect populations, each year at least 100 island foxes are vaccinated on each island against this deadly dog disease and rabies. On Catalina the goal is to vaccinate 350 island foxes, because the threat of introduced disease is so much higher for this population.

Island foxes are so susceptible to CDV that they can not tolerate the vaccine commonly given to dogs. They must be vaccinated with a special dead-virus vaccine that is produced in small batches and only provides protection for less than a year.

That means island foxes need to be vaccinated annually and the effort is one of the more expensive measures taken to protect their health each year.

This year's 650 vaccinations were supported by:

  • Island Fox Ambassador Schools & Projects
  • Local organizations 
  • Recycling 4 Island Foxes & the Planet
  • USU Recycles 4 Island Foxes
  • 2024 FIF Island Trip participants 
  • Private donors
  • a grant from the Fresno Chaffee Zoo Wildlife Conservation Fund

Radio Collars and Vaccines Arrive for Island Foxes


Island fox populations are stable across the Channel Islands, but recovery is only as sustainable as our participation in protecting them from introduced threats.

Radio Monitoring

Radio-tracking collars remain the best technology for monitoring island fox survival. These collars allow biologists to determine from a distance that an island fox is alive and active in its habitat. If something happens to a fox and it stops moving for 6 hrs, the radio collar signal changes, alerting biologists that something has happened to that individual island fox. Quick response to the death of a collared fox allows new diseases or other threats to be discovered early–protecting the rest of the uncollared population. 

New and refurbished radio collars have just arrived.

  • 5 new and 15 refurbished radio collars for Santa Cruz Island
  • 24 refurbished radio collars for Santa Rosa and San Miguel Islands

44 radio collars will be fitted on island foxes over the next few months. They were funded through:

 

Vaccinations Against Distemper and Rabies

Despite vaccine price increases, you helped FIF raise the $13,571 needed to vaccinate 650 island foxes in 2023.

Vaccine for rabies and canine distemper has gone out to Santa Cruz, Santa Rosa, San Miguel, and Catalina Islands. On the three northern islands, 100 foxes will be vaccinated during health checks, while 350 island foxes will be vaccinated on Catalina. Why are more foxes vaccinated on Catalina?

It takes a community to vaccinate island foxes:

Every donation makes a difference for island fox survival.

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

Friends of the Island Fox Vaccinates Island Foxes

You're making a HUGE difference for island foxes this summer.

Biosecurity is a major concern across the Channel Islands. Disease, especially viruses, can be introduced through unvaccinated pets, people, and wildlife species that are not native to the islands.

The island foxes on Catalina Island face the greatest potential biosecurity threat because their home is visited by millions of people

Friends of the Island Fox just purchased over $5,100 worth of vaccines to vaccinate 350 Catalina Island foxes this summer. Island foxes captured for health checks will receive two vaccinations:

  • Canine distemper virus: It's the equivalent of measles in humans. This virus is highly lethal to island foxes and killed over 90% of the Catalina Island fox population between 1998–2000. Even with a great deal of human assistance, it took until 2016 for the population to recover.
  • Rabies virus: Rabies is lethal to island foxes and dangerous to humans. Just like with dogs, the best protection is prevention.  

 

It costs $20 to vaccinate and protect an island fox.

Help A Fox Day - Protect Island Foxes


On this summer day you can help one rare fox survive.

What's in these vials? A vaccine that protects island foxes from canine distemper virus (CDV).

It takes $20 to vaccinate an island fox against CDV and rabies. Donors like you have helped Friends of the Island Fox purchase these vials of vaccine. We are committed to providing vaccinations for 300–350 island foxes on Catalina Island in 2021. 

But we still need to raise another $2,000!


Help FIF vaccinate island foxes!

CDV spreads rapidly through island fox populations and few survive. This virus caused the death of over 90% of the Catalina Island foxes in the late 1990s.

In 2021 - CDV is prevalent on the mainland in the Long Beach area, across from Catalina Island.  

CDV is carried by raccoons and other wildlife, as well as pet dogs. Make sure your dog is vaccinated against canine distemper virus and help island foxes stay safe too.

 

$20 protects an island fox for a year!

Distemper Outbreak in Long Beach Raises Threat to Island Foxes

courtesy of M. Baffa

April 15, 2021 the City of Long Beach issued a press release "Animal Care Services Reports Distemper Outbreak." The city reported that "38 raccoons and at least one skunk" had been found with the highly transmissible disease: canine distemper virus (CDV). 


This is the kind of situation that led to the serious decline of the Santa Catalina Island fox between 1998–2000. A wild raccoon infected with canine distemper virus was unknowingly transported to the island. Canine distemper virus killed 90% of the Catalina Island foxes within months and necessitated a multi-year effort to recover their population.

CDV can easily be passed from wildlife to pet dogs through direct contact or the sharing of food or water bowls. You can help protect the island fox and your pets. Vaccinate your pet dog against canine distemper virus. A vaccinated pet is protected and stops transmission from continuing. When there are high levels of CDV on the mainland, the threat to island foxes magnifies.


There are currently over 2,000 individual island foxes on Catalina Island. CDV is especially deadly to puppies and island fox pups. Island fox pups were born across the islands in April; they will be especially vulnerable for the next few months.

Friends of the Island Fox is raising funds to assist the Catalina Island Conservancy in vaccinating 300–350 island foxes on Catalina Island this summer. That is still only around 15% of the population. Vaccinating island foxes is the best chance for protection.

There are several months between now and when island foxes will be vaccinated. You can help protect island foxes from this heightened disease threat:

  • Vaccinate your dog against canine distemper
  • Do not feed wildlife, especially in harbor or port areas
  • Dispose of trash in secured bins so wildlife can not access it
  • If you have a boat, or know someone who does, always be aware of wildlife that may be hiding on board. If you detect a raccoon or other animal, return to port, DO NOT continue on to Catalina. Be wary of transporting any wildlife or feral animals to Catalina or any of the Channel Islands.
  • Consider donating to FIF - a $20 donation will vaccinate an island fox against canine distemper virus and rabies.


Island foxes need all of us to be vigilant and stop the spread of this current CDV outbreak.

Your donation will help vaccinate island foxes against deadly canine distemper virus.

500 Island Foxes Protected Against Canine Distemper Virus

Canine Distemper poses a serious threat to endangered Channel Island fox populations across all six islands where they live.


Thank You! 
to everyone who donated and helped us reach our goal of


 

Introduced disease is a major concern for these isolated populations. Working as a community of concerned citizens, you have helped to assure that even if catastrophic disease is introduced 100 individual island foxes will be protected from disease on each island.


 The annual counting of Channel Island foxes and providing of health checks has recently concluded for the 2015 year. See what it's like to work as a field biologist counting island foxes. 


The biologists will be taking the data they have collected this fall to estimate island-wide population numbers and trends. We know that drought has impacted some island fox populations. We will see if scattered spring and summer rains improved island resources.

Thank you again to everyone who helped support FIF's 2015 vaccination fundraiser.
