Fire Foxes - Catalina Island Fox Update

Early reports on island foxes surviving the Catalina Island fire are very hopeful.

Ann Muscat of the Catalina Island Conservancy

“Habitat damage is extensive and will require further analysis. There is no obvious loss of larger wildlife (eagle chicks in nest, deer, bison, foxes). Our staff was able to fly over the Island and monitor for 48 radio-collared foxes and all signals were picked up. This is very good news. Foxes are in the pupping season, however, and staff are now surveying the burn area for females in their dens to see if pups are surviving. A number of iron wood and oak groves were lost, but until we can overlay our vegetation maps onto the fire area, we will not know the full extent of the loss of rare and endangered plant species.”

Julie King, Senior Wildlife Biologist, Catalina Island Conservancy adds the following fox details about four foxes that were sighted in the burn area. Three were non-injured, but one female fox with “severe burns to all four paws, severe dehydration and malnutrition” was captured. The “fox is being treated in the Middle Ranch Veterinary Clinic under the direction of Institute for Wildlife Studies veterinarian Dr. Winston Vickers. An additional fox was captured in the process, a large healthy male, was given a workup, fitted with a radio collar and released at the location of capture.”

As of Saturday, May 26, 2007:

We'll be setting traps all weekend to get a better assessment of potential injuries in the burn area. I'll be sure to keep you updated if we get any additional injuries. On a happy note, the fox we are treating is responding very well to treatment. When caught, she was only 1.2kg and she's now up to 1.7kg. She's eating well and so far there is no sign of infection in her paws. It has only been 5 days, but her feet do appear to be slowly healing. She has a long road ahead of her, but she's doing much better than we had initially expected. Dr. Vickers will be out on June 4th to do an assessment. - Julie King

As the information from the Catalina fire area becomes available we will post it here. Friends of the Island Fox is rallying our resources to see what we can do to help the Catalina island foxes. These island fox survivors of the fire need our support more than ever.

Friends of the Island Fox Supports Integrated Fox Conference

Saving the endangered island fox requires the efforts of caring and knowledgeable individuals from around the country. The Integrated Fox Conference brings all of these people together once a year.

The third week in June, biologists and scientists will meet with conservation professionals and land managers for each of the Channel Islands to report on the current status of all six subspecies of island fox and to make conservation decisions for the upcoming year.

To support the efforts of the Integrated Fox Conference, this year Friends of the Island Fox is providing a grant to the U. S. National Park Service to help offset the transportation costs of the four veterinarians that provide care to the foxes on the islands and who do veterinary laboratory work during the year. These devoted people help maintain the health of island foxes and move quickly when disease threatens this endangered population.

• Karl Hill, DVM - Santa Barbara Zoo
• Karen Blumenshine, DVM - Wildlife Services Associates
  
• Winston Vickers, DVM - Institute for Wildlife Studies
• Linda Munson, DVM-PMI - University of California, Davis

The Integrated Fox Conference is sure to bring to light unexpected successes and new conservation challenges regarding the island fox. FIF will post a summary of the Conference, including an update on the status of island foxes on Catalina Island after the fire.

FIF thanks all of you who have donated toward island fox conservation during the first half of 2007. Your contributions have made this grant possible.

Fire and Foxes on Catalina Island - Update

Just a quick Update on the island foxes on Santa Catalina Island.

Friends of the Island Fox has been in communication with the Catalina Island Conservancy (CIC). The few individual island foxes that are in captive care for health problems and Tachi, CIC's education fox, are all fine. (For more about Tachi)

As of Thursday May 17, the fire is completely out. Now biologists are beginning the task of trying to locate radio collared island foxes to determine if there were any fatalities due to the fire.

CIC will make their full report at the Fox Conference in mid June. A complete summary of all island fox conservation successes and issues will be posted here following the Conference. (most recent look at island foxes on Santa Catalina Island)

Thank you for your concern about the island foxes in the face of this recent fire threat.

Fire and Foxes on Catalina Island

As of 6 PM Friday May 11 the wildfire on Catalina Island appears to be 35% contained. The current situation is an unfortunate example of the delicate nature of island habitats.

Officials from the Catalina Island Conservancy report:

Bald Eagles
The bald eagle chicks that recently hatched on the island are safe. The nests are on the eastern end of the island and not near the fire area. (more on the new bald eagle chicks)

Island Foxes
Currently the effect of the fire on wild island foxes is unknown. Radio collars on individual foxes will be vital in locating individual animals and determining if any have been overwhelmed by the wildfire.

This is another situation that highlights the importance of radio collars on the endangered island foxes on San Miguel, Santa Rosa, Santa Cruz and Santa Catalina Islands. Island foxes are currently having their pups on the islands. This new generation will soon need radio collars.

You can help make sure all endangered island foxes have radio collars.

Bald Eagle Update: Spring 2007

The recovery of island fox populations on the northern islands is linked to the successful return of bald eagles to the Channel Islands. (Why bald eagles went extinct on the Channel Islands in the 20th century)

Bald eagles stake out territory for themselves and help to keep out golden eagles which prey on unsuspecting island foxes.

This spring has been filled with wonderful successes for nesting bald eagles on the Channel Islands.

• U.S. Fish & Wildlife reports “Two Bald Eagle Chicks Hatch Unaided on Catalina Island”
• Catalina Island Conservancy announces “Third Bald Eagle Chick Hatches Naturally on Catalina Island”
• Channel Islands National Park finds bald eagles nesting for the second year on Santa Cruz Island
• You can watch the bald eagle chicks grow up via NestCam as part of the Catalina Island Bald Eagle Restoration Project conducted by the Institute for Wildlife Studies.
• Hear the Latest Bald Eagle News from Dr. Peter Sharpe, Institute for Wildlife Studies when he talks on “Bald Eagle Restoration on the Channel Islands” at Channel Island National Park Wednesday May 9 at 7:00 PM.

Each Channel Island is a delicate ecosystem. Restoring habitat and supporting a healthy bald eagle population is vital to saving the endangered island fox.

Island foxes are presently having their pups out on the islands. Stay tuned for Updates from the Fox Conference in June and come support Friends of the Island Fox at the Los Angeles Zoo & Botanical Gardens’ Fox Festival Saturday May 19th.

Six Islands, Six Different Island Foxes

Island foxes are found on six of the eight Channel Islands off the coast of southern California. (Where does the island fox live? What is an island fox? Experiencing Santa Cruz Island )

Island foxes all have similar lifestyles and habits:

• About the island fox
• Males consistently weigh more than females
• What do island foxes eat? Their favorite food is the deer mouse. (Each island has its own subspecies of deer mouse.)
• Island foxes are good climbers, which allows them to reach bird nests and eggs
• Island fox pups are born in the spring. Island foxes usually have 2-3, but may have as many as 5 pups

But the foxes on each island are slightly different from each other. The differences are great enough that each island has its own subspecies of island fox.

National Park Service biologist Tim Coonan points out that the San Miguel island fox weighs significantly more than the island foxes on the neighboring island of Santa Rosa.

Tail length is a specific physical trait that varies between the different subspecies. Studies show island foxes from different islands have more or less tail vertebra.

In descending order:

1. San Nicolas Island 22 tail vertebra
   
2. Santa Catalina Island 21 tail vertebra
3. San Clemente Island 19 tail vertebra
4. Santa Rosa Island 19 tail vertebra
5. Santa Cruz Island 19 tail vertebra
6. San Miguel Island 15 tail vertebra

Between the shortest-tailed island foxes on San Miguel Island and the longest tailed on San Nicolas Island there is a difference of 7 vertebra. Interestingly, Schoenherr, Feldmeth and Emerson point out in Natural History of the Islands of California (Univ. of California Press 1999) that the island foxes on San Nicolas Island appear to have the least amount of genetic diversity. This suggests the San Nicolas population may be descended from as few as a single pair of foxes.


All of the island fox populations are vulnerable because they live in such limited habitats. Small population numbers mean that a single introduction of a disease, like the canine distemper outbreak on Santa Catalina Island, can threaten an entire island fox population. (Santa Catalina island fox Update) Catastrophic events, like the arrival of an unexpected predator–the golden eagle–can cause near extinction.

The island foxes on San Miguel Island were reduced to only 15 individuals because of predation by golden eagles. This genetic bottleneck means future San Miguel Island foxes will be more genetically alike than they were in the past.

Conservation and research efforts are necessary across the islands to preserve and protect the six subspecies of island foxes.

Donations to Friends of the Island Fox supports conservation and education efforts to Help Save all six subspecies of island fox. See how your donations can make a difference.

Island Fox Update - Santa Catalina Island

The island foxes on Santa Catalina Island face different survival challenges than the foxes on the northern islands.

In 1999, the Santa Catalina island fox population declined by over 90%.

Only approximately 100 foxes remained because of an outbreak of canine distemper virus. In this emergency situation, the Catalina Island Conservancy (CIC) and the Institute for Wildlife Studies (IWS) created a captive breeding facility to help reestablish a stable fox population. Twenty-two island foxes from the West End of Catalina Island, where the animals were unaffected by the virus, were translocated to the affected East End. A distemper vaccination program was also implemented.

[The fox pictured is Tachi, CIC's education fox. More about Tachi.]

After several successful years, captive breeding efforts concluded in 2004. Since then, the Catalina island foxes have been recovering their numbers in the wild.

Foxes are counted by setting cage traps in specific places, such as the location marked by the colored tag on this bush. The total number is estimated from individuals that are caught. Trapping also allows biologists to check the health of individual foxes and vaccinate them against distemper. The CIC estimates in 2007 that there are approximately 500 island foxes on Catalina. This population is doing well but still has a long way to go to reach the pre-outbreak estimate of 1,342 foxes.

Today, however, the Catalina island fox is facing new threats. Since 2001, over 37 foxes have been found with cancerous ear tumors (Ceruminous gland carcinoma). These mysterious ear lesions are typically fatal. Currently, the Catalina island fox is the only subspecies with this disease. The Catalina Island Conservancy is supporting research that is being conducted by IWS and the University of California, Davis to determine the prevalence and possible causes for this cancer.

The island foxes on Santa Catalina also have the challenge of sharing their island with people and domestic pets. Cars on the few island roads have been responsible for 9 fox deaths in the past two years (2005-2006). While three more foxes were attacked and killed by domestic dogs.

Signs warning “Watch for Foxes” are one way to alert drivers and new pet policies for the interior of the island require residents and visitors to vaccinate their pets, keep them leashed and to clean up after them.

When visitors dock their boats in Catalina’s harbors they may not be aware of the island fox, just on shore. Friends of the Island Fox hopes to support the Catalina Conservancy in further island fox disease research and public education to help the residents and visitors on Catalina Island understand their role in providing a safe habitat for island foxes.
