Children Helping Island Foxes

Help for island foxes comes from many places. Recently Friends of the Island Fox received this wonderful letter from a concerned student.

Working with her school friends and family, Autumn raised $155 dollars to help island foxes. Her donation can: 
No effort to help island foxes is too small. When we all work together, we can make big things happen. 

Autumn joins our growing group of Island Fox Ambassadors - she is helping tell the island fox's story to her community and working to keep island foxes healthy and safe into the future.

Yared raised funds and then traveled all the way from Virginia to visit the island fox.

Meet some other Island Fox Ambassadors:
At the Buckley School students had a huge bake sale and one student designed and sold a T-shirt. 

You can become an Island Fox Ambassador too. Individuals, classrooms, grades, even schools and organizations have become Island Fox Ambassadors.

Island Fox Ambassadors:
  • raise awareness about the island fox
  • they work on a service project to benefit island fox conservation
  • they share their efforts with others
Service projects can raise funding, contribute to habitat restoration, or develop a conservation project to help island foxes and other wildlife (such as an effort to vaccinate local pets so they don't transmit disease to wildlife).

Friends of the Island Fox Helps Save Island Foxes on Catalina Island

What is the biggest threat to island foxes on several islands? 

Being hit by a car! 
(See Island Fox Update 2018)

Island foxes are small, camouflaged for their environment, and vulnerable to speeding cars.

Thanks to Friends of the Island Fox a speed-detecting traffic sign on Catalina Island is back in operation slowing down drivers. 

I'm happy to report that with funding from FIF we have repaired our radar speed detector and deployed it on the landscape! says Lara Brenner, Wildlife Biologist for the Catalina Island Conservancy. In the next few days I will take some time to hide in nearby brush and monitor the speed machine's efficacy at convincing people to slow down. Thank you so much for your continued support of our fox program. We hope to continue working with you to decrease the impact of vehicles on the Catalina island fox population.

The traffic sign is again alerting drivers to SLOW DOWN and watch for island foxes.

Some road areas are more deadly to island foxes than others. Reducing island fox access to human food and trash, deters these tiny animals from crossing busy roads. Friends of the Island Fox is also committed to replacing old and dangerous trash cans on Catalina with "Fox-Saver" bins and putting fox-proof food lockers in campgrounds. When island foxes are denied access to human food and trash they are healthier and safer.

Thank you to ALL of our DONORS who helped fund this important fox-safety effort on Catalina. Working with the Catalina Island Conservancy, we can make sure Catalina Island foxes continue to have a solid recovery and healthy future.

Fox Foto Friday - Surviving the Heat

Summer heat is impacting the Channel Islands and island foxes just as much as the mainland.

High temperatures and low rainfall increase the challenge for island foxes to find food. Just like with people, high temperatures put greater stress on the young and the old. 

Island fox numbers are good across the islands (See the Island Fox Update 2018), but fox biologists warn that 2018 may be a harder year for island foxes.

Thank you to Michael Lawshe for this great photo of an island fox searching in the dry grass.

Island Journal - Sometimes You See Where A Fox Has Been

The opportunity to visit Channel Island foxes in their natural environment is part of the success of saving island foxes from extinction. Friends of the Island Fox loves to highlight individual experiences. On Santa Cruz Island there are locations where you almost always see island foxes (Scorpion Campground and Prisoners Harbor). Guest writer Michael Lawshe has a different story from Santa Rosa Island.

Island Journal: Santa Rosa Island, June 16, 2018

We took an 8 am boat out of Ventura, with Island Packers, directly to Santa Rosa Island. The sky was overcast and the sea was remarkably flat. We crossed the channel, passing Anacapa and Santa Cruz Islands to...

Taking a hike, we noticed dozens of great little caves and crevices in the hillsides. 

Perfect for a fox!

Sometimes you see a fox, sometimes you see where they have been! 

Here is a path to a secluded fox resting place.

Do you see the little footprints in the sand?

They're a little bigger across than the size of a quarter. 

We didn't see the island fox, but we are pretty sure they were watching us. It was a great day. - Michael Lawshe

2018 Channel Island Fox Update

2017 was a successful year for island fox pups!

In May, the Island Fox Conservation Working Group gathered to report on the status of island foxes across the Channel Islands. The population numbers reported here reflect the annual counting effort from late summer/fall 2017. Land managers are currently in the field counting island foxes and providing health evaluations.

For most islands, the spring rain in 2017 resulted in greater pup survival and higher population numbers. The larger islands, Santa Rosa, Santa Cruz, and Santa Catalina, all documented population highs. The larger islands have greater plant diversity and therefore a greater variety of food resources for island foxes.

Along with these higher population densities (more foxes per kilometer) come increased concern for problems brought to the islands from the outside world: introduced disease and introduced parasites carrying disease.

blood taken during health exams is checked for disease
While the four island fox subspecies that were close to extinction in 2000 have all recovered, higher density means disease can spread more rapidly through a population. On Catalina, serology testing in 2015-2017 revealed canine Adenovirus (CAV-1) marching across Catalina within months. This virus causes "kennel cough" and canine hepatitis. Fortunately, there have been no identified island fox fatalities from the disease, but it demonstrates the fragility of these isolated populations.

2017 - Year of the Tick

Across the islands ectoparasites, parasites that live on the outside of the fox's body, have been increasing in drought years. Some islands have had more problems with fleas and lice, while others have seen increases in ticks. This past year, two tick-borne diseases were identified for the first time on Channel Islands; Lyme disease (Borrelia burgdorferi) was found on both Catalina and Santa Cruz Islands and a related disease, relapsing fever (Borrelia miyamotoi) was identified on Santa Rosa Island. Both diseases are known to impact dogs and humans. Understanding the extent of these tick-borne diseases is a priority. Ticks are being collected from island foxes and pathology will need to be run on tick specimens to determine if they carry these or other viruses. What is the extent of these diseases in the tick population? How has island wildlife been impacted? Pathology runs $15 - $50 per tick depending on the necessary tests. 

Friends of the Island Fox is committed to helping land managers with this new cost. Understanding the disease threat in the tick population is vital for island fox survival and human health. Parasite testing and serology have become a new focus in 2018.

Island Fox Update 2018 pdf provides a detailed island-by-island status report for island foxes. In summary:

The smaller islands face more immediate challenges and population volatility.
  • San Miguel Island ~ 260 foxes (low of 15 in the year 2000) - The population has recovered from extinction threat and is trying to stabilize. Concerns: Drought impact on food resources and an increase in life-threatening parasites. (see Island Fox Update 2018 above) Research is needed to understand how a new parasite is accessing the fox's diet.
  • San Clemente Island ~ 770 foxes - This Navy island has a robust population, but drought has impacted food resources and the fox population has adjusted downward. Concerns: Fatalities caused by cars have increased dramatically in the past year, (for more see Island Fox Update 2018 above)
  •  San Nicolas Island ~ 416 foxes (low of ~250 in the year 2015) - The dramatic decline on this Navy island, which began with the drought in 2013, seems to be stabilizing. More pups survived in 2017 and there were fewer emaciated individuals. Efforts to re-establish native vegetation may be providing more direct and indirect food for island foxes (for more see Island Fox Update 2018 above). Concerns: Parasites may have added to poor health in some individuals. A return to drought conditions could further challenge this island.
The larger islands have greater biodiversity of plant and prey species to support island foxes and enable island foxes to adapt to challenges, like changing climate. This is an important conservation lesson: habitats with reduced natural biodiversity are less likely to offer survival options when challenged by negative pressures. Foxes across the larger islands did very well in 2017 (see graph at top of story).

  • Santa Rosa Island ~ 1,850 foxes (low of 15 in the year 2000) - The population has recovered from extinction threat and continues to thrive. Concerns: Tick-borne disease and an unusual fatal parasite, Leptospira, have been introduced to this island (see Island Fox Update 2018 above). Research is needed to quantify the threat to island foxes and people. 
  • Santa Cruz Island ~ 3,150 foxes (low of 80 in the year 2000) - In 2017, Cruz was home to the largest known population of island foxes ever recorded. Concerns: Tick-borne Lyme disease was introduced to this island. The introduction of other diseases is a major concern (see Island Fox Update 2018 above). 
  • Santa Catalina Island ~ 2,047 foxes (low of 103 in the year 2000) - In 2017, Catalina reached it's highest recorded island fox population. Fox saver bins and road signs are reducing island fox deaths from car strikes. Concerns: Tick-borne Lyme disease was introduced to this island and the threat from human impacts (introduced disease, cars, and aggression from pets and feral animals) is greatest on this island (see Island Fox Update 2018 above). Successful reunion of an island fox pup and its mother.  
2017 was a successful year for island foxes, but all land managers agree: Lower rainfall in 2018 may reduce resources leaving island foxes with less support for this year's pups. Even the larger islands may have reached or be reaching carrying capacity - the greatest number of individuals that can be sustained in a habitat. Population numbers are not expected to increase in 2018.

Friends of the Island Fox continues to support important conservation efforts for island foxes: radio-monitoring collars, vaccinations against canine distemper and rabies, ID microchips, blood testing for disease (serology), and items that reduce human impacts "Fox-saver" bins and road signs.

Tick-borne disease is a new and potentially long-term threat to island fox survival. The sooner the threat can be understood, the better the outcome will be for island foxes and people.

Island Fox Success Story - Pup and Mother Reunited

island fox pup
Island fox recovery is a success story, but sometimes it is nice to focus on individual successes.

This May an island fox pup, only a few days old, was separated from its parents. It was so young, its eyes were still closed. When the pup was found on a dirt road on Catalina Island, it was weak and hungry. Biologists with the Catalina Island Conservancy rallied to the pup's aid. Veterinary care was provided and after two weeks, the pup was healthy enough to be returned. But the clock was ticking on a possible reunion and acceptance from its fox family.

Returning to the area where the pup was found, biologist Lara Brenner and Emily Hamblen captured adult island foxes, including a female who showed signs of lactating. After observing interactions between the pup and the female, the pup was allowed to approach the female and it immediately began nursing. Mom and pup were reunited. The mother fox was radio-collared so that the biologists could locate the family and check in to see how the pup was doing. But getting everyone safely returned to the wild was a challenge. Watch the heart-warming story of mother and pup.

Three cheers for a brave island fox pup, a devoted mother fox, and the determined Catalina biologists who facilitated a successful reunion.

Friends of the Island Fox supports the CIC Fox Program with radio collars, fox health measures and "Fox-safer" trash cans. With your help, FIF replaced the electronic elements of traffic speed sign on Catalina in 2018 to help slow down drivers on a section of road dangerous to island foxes.

Working together to make island foxes and people safer on the Channel Islands.

What Has Arrived at Channel Islands National Park?

 Radio collars!

Five new radio collars
still in the wrapper
Six refurbished radio collars
all rebuilt and ready to go back on island foxes!
...have arrived at Channel Islands National Park. These radio-telemetry collars will be fitted on island foxes in the next few months as biological technicians count island foxes and check their health.

Your donations funded these radio collars!

Look closely, this island fox is wearing a radio collar
Foxes with worn collars will be giving them up for refurbishing or new batteries. You have funded fourteen more of these collars to go from the field to the workshop for refitting. More on Refurbished Radio Collars

Radio collars offer a frontline of defense for monitoring and protecting island foxes.

Fox Foto Friday - What is that fox doing?

You guessed it! She is marking her territory with urine. Island foxes are very territorial. Territory = food resources. Food means she and her mate can support a litter of pups.

Thanks to Daniel for taking this great photo on a trip to Santa Cruz Island with Friends of the Island Fox. Interested in traveling to see island foxes? Subscribe to the FIF newsletter for info on upcoming trips.

Marking territory with urine communicates through scent to other island foxes. Both male and female island foxes mark territory with urine and with scat.
