Santa Cruz Trip with FIF

Join Friends of the Island Fox for:

A Trip to Santa Cruz Island
Saturday, May 5, 2012
to Look For The Island Fox

Please join us when we visit Santa Cruz Island for a tour with our educators.  We will look for the endangered island fox, plus the many other endemic species, both plants and animals, found only on this island and nowhere else.  On the trip over to Santa Cruz (about 1 hour) there is the possibility of seeing many marine species.

Tickets for adults will be $65.00 per person, children $55.00. A percentage of the fee will go to support island fox recovery efforts.

We will take the Island Packers boat from Ventura Harbor leaving at noon and returning around 5 PM on Saturday May 5, 2012.  Check in will be required at 11:15 AM

Reservations are limited and will be provided on a first come basis. To book reservations, please download the Reservation Booking Form (Click Here to download pdf)

Send the completed form with your check, made payable to the "Friends of the Island Fox" to the address on the form.  Reservations will be taken in the order received, and no reservations can be accepted without payment.

Before the island visit you are welcome to join us at 9:30 AM at the Channel Islands National Park Visitors Center at 1901 Spinnaker Drive, Ventura.  We will tour the native plant garden, visit the Center and you will have the chance to view the Channel Islands National Park film “Treasure in the Sea” narrated by Kevin Costner. 

At the time of booking you will receive further details of the trip, including where to meet, what to pack, the suggested clothing and other items of interest. Note the photo above. Food items will need to be secured at all time. What to remember when visiting the island fox.

Climate and Island Foxes

Santa Catalina Island
Across the six islands that are home to island foxes (Habitat), pairs like Tani and Tiptu are breeding and finding an appropriate den site. Island fox pups are typically born in late April.

Like all wild animals, island fox reproduction is impacted by the amount of local resources–food, water and territory. As endangered populations of island foxes have recovered, there have been several years where female foxes have had large litters of pups. Typically two pups are born in a litter, but when resources are abundant there can be as many as five pups.

Because the recovering endangered populations were small, there was little competition for territory and food. In the mid-2000s, it was not unusual for island foxes on San Miguel to have litters of three to five pups. With large litters of offspring the San Miguel Island population, that had nearly gone extinct in 2000 when there were only 15 surviving individuals, was able to exponentially increase each year.  Graph

But severe climate can greatly reduce the resources available to island foxes. 2007 was the driest year on record in southern California since National Weather Service records began in 1878; less than four inches of rain fell. The lack of rainfall reduced the plant foods on the islands which reduced the deer mice, insects and bird life. Without winter rains, the Catalina cherry, native currants, toyon and other fruit producing plants produced less fruit for the foxes to eat. Less food, meant fewer island fox pups were born or survived. The winter seasons of 2008 - 2011 averaged approximately 12 inches of rain, the low side of normal, but still enough that Channel Island wildlife flourished.

This winter season is showing early signs of drought. As mid-March approaches the Los Angeles area has received less than six inches of rain. This year if spring rains do not arrive, we may see fewer island foxes born and fewer that will survive. Climate fluctuations act to moderate animal and plant populations, but climate change means greater weather extremes. Drought in 2012 could make it more difficult for young island foxes like Tani to successfully reproduce and could slow down the recovery of endangered island foxes.
