Over the last four decades, the National Park Service and its partners have invested over $20 million in protecting the native species of the Channel Islands through the removal of harmful, nonnative species, including rats, cats, ungulates, Argentine ants, and a variety of weed species. Starting in 2014, Channel Islands National Park, The Nature Conservancy, and the U.S. Navy developed a joint biosecurity program to prevent, detect, and respond to nonnative species introductions. Preventing the re-introduction and establishment of nonnative species is vitally important to preserving the nearly 150 endemic plant and animal species of the islands. As a visitor, you play a valuable role in helping to protect that biodiversity.
Firewood or any untreated, unfinished wood (including hiking sticks)
Tools or equipment with attached soil
Single-use plastic bags
These restrictions are necessary to protect the breeding populations of marine mammals, endangered species of seabirds, eagles, islands foxes and the other unique and rare species of flora and fauna inhabiting Channel Islands National Park.
Trails are pathways for more than just people. Weeds often spread along trails and into adjacent un-infested areas. You can help prevent this by always staying on designated trails, avoiding weed-infested areas, and by not picking or transporting plants when hiking on the islands. Pack out all trash too. Just because a bit of trash is organic —apple cores, orange seeds, etc.— doesn’t mean it can be left behind. While most domestic fruit and vegetable species are not invasive, some can germinate and become pests.
Campfires are prohibited on the islands. In addition to the threat of wildfire, firewood brought from the mainland can harbor harmful organisms. A prime example is the fungal-like disease "Sudden Oak Death," which can attack several species of native trees. You can help prevent the spread of such threats by not transporting firewood under any circumstances.
