Endangered Species Act Day 22, Channel Island Fox. I've had the opportunity to watch these small foxes while visiting the Channel Islands. This is an Endangered Species Act success story. Although foxes have always existed at low population sizes, four island fox subspecies underwent catastrophic declines in the 1990s. On San Miguel, Santa Rosa and Santa Cruz Islands at Channel Islands National Park, the decline was attributed to predation by golden eagles. The presence of non-native Sheep as a food source in addition to the DDT-caused decline of bald eagles, a natural competitor, facilitated the establishment of golden eagles as resident breeders on the islands. By 2000, predation on island foxes resulted in population declines to 15 individuals on San Miguel and Santa Rosa Islands, and less than 80 on Santa Cruz Island. In 2004, each of the park's island fox subspecies were federally listed as endangered.
In 1999, Channel Islands National Park began an island fox recovery program that included captive breeding and reintroduction of foxes, removal of resident golden eagles, re-establishment of bald eagles, and removal of non-native ungulates. This coordinated, organized and highly focused strategy was able to reverse the certain extinction of an endangered population. Today, the population has recovered within the park. Population trend and annual survival are currently monitored to ensure that recovery continues and future threats to the park's island fox subspecies are identified. #endangeredspeciesact #esa #resist #fox #timelapse #timelapsedrawing #greyfox #foxart #whatdoesthefoxsay
