USFS Issues Rattlesnake Warning for Southern California After Fatal Bites
The U.S. Forest Service has issued an urgent rattlesnake warning for Southern California after two recent fatalities and multiple bites; officials say warmer-than-normal March weather has rattlesnakes emerging earlier, increasing risk for hikers, families and pets.
Key takeaways
- USFS alert: San Bernardino National Forest rangers warn of higher rattlesnake activity tied to unusually warm spring conditions (CBS Los Angeles; KESQ).
- Recent fatalities: Two deadly rattlesnake bites in Ventura and Orange counties have focused attention on trail safety (Los Angeles Times; CBS Los Angeles).
- What to do: Stay on trails, keep pets close, wear protective clothing and seek immediate medical care if bitten.
What the U.S. Forest Service warned
San Bernardino National Forest rangers posted a social media notice on March 25, 2026 explaining that rising temperatures are making rattlesnakes more active and urging visitors to be cautious. The post advised:
“As temperatures rise, rattlesnakes become more active in the forest. Stay alert, watch where you step and keep pets close.”
Rangers also added guidance to avoid disturbing wildlife and to give snakes plenty of space if encountered (CBS Los Angeles; KESQ).
Recent incidents in Southern California
Several bites and sightings across the region have raised concern:
- Ventura County: Gabriela Bautista, 46, of Moorpark was bitten while hiking at Wildwood Park on March 14 and died March 19 from rattlesnake venom toxicity. Ventura County reported multiple bites since mid-March, including in Thousand Oaks and Meiners Oaks (CBS Los Angeles; Los Angeles Times).
- Orange County: Julian Hernandez, 25, was bitten on Feb. 1 on a trail at Quail Hill in Irvine and died on March 4 despite medical treatment (CBS Los Angeles; Los Angeles Times).
- Riverside County: In early March a hiker near a Moreno Valley trail was bitten, airlifted and survived after hospital care (CBS Los Angeles; KESQ).
Local reporting and social media also show increased sightings in coastal areas — for example Huntington Beach — where warmer weather has drawn snakes into areas used by hikers, bikers and beachgoers (local sighting video report).
Why sightings are up now
Wildlife experts and USFS officials point to an early, unusually warm spring as the main cause. Rattlesnakes normally spend colder months in dens and are less active; higher temperatures bring them out sooner and for longer periods. Records show March has been abnormally sunny and warm in parts of Southern California, increasing human–snake encounters (CBS Los Angeles; VVNG).
Behavior and sheltering: USFS officials note rattlesnakes can strike up to their full body length — sometimes more than five feet — and often shelter in shade, rock crevices, piles of leaves, tall grass and near water. Regional species include the Western diamondback and Southern Pacific rattlesnakes, recognizable by distinct markings and a tail rattle (CBS Los Angeles).
How to reduce risk: practical safety tips
USFS rangers and public-health officials recommend the following to reduce encounters and injuries. These tips are aimed at residents, trail users and families with pets.
- Stay on the trail. Avoid shortcuts through tall grass, brush or rock piles (CBS Los Angeles).
- Watch where you step and put your hands. Look before stepping over logs or reaching into crevices (VVNG).
- Keep pets close. Use a short leash; dogs and small animals are often bitten first (KESQ).
- Wear protective gear. Long pants and sturdy boots can help protect lower legs (CBS Los Angeles).
- Give snakes space. Stay at least six feet away, back away slowly and do not handle, move or kill the animal (CBS Los Angeles).
Bite response: what to do and what not to do
If a person is bitten:
- Do: Call 911 immediately; keep the person calm and still to slow venom spread; immobilize the limb and keep it lower than the heart if possible; cover the bite with a clean, dry dressing and remove jewelry or tight clothing before swelling begins (CBS Los Angeles; KESQ).
- Do not: Do not use tourniquets, cut or attempt to suck out venom, or apply ice; avoid giving alcohol or caffeine. These measures can cause more harm (CBS Los Angeles).
Note: Some local reports described variations in first aid; major medical guidance emphasizes immobilization, prompt transport and avoiding harmful field treatments (Los Angeles Times).
Identifying poisonous species
Common rattlesnakes in Southern California include the Western diamondback and the Southern Pacific rattlesnake. Typical features: triangular head, vertical pupils and a rattle at the tail tip. Not all rattlesnakes rattle; many rely on camouflage, so visual caution is essential (CBS Los Angeles).
San Bernardino National Forest safety: what rangers are doing
Rangers have increased outreach, posting warnings on social media and placing informational signage at trailheads. They remind visitors about peak activity times — early morning and evening — and ask people to report sightings so rangers can monitor trends (CBS Los Angeles; VVNG).
Implications beyond public safety
Economic: Increased rattlesnake activity can affect outdoor recreation businesses, guided tours and local economies dependent on hikers, bikers and campers. Reduced visitors or trail restrictions could impact small outfitters (CBS Los Angeles).
Political and social: Local leaders and land managers may face pressure to boost safety measures, education, signage and ranger staffing. Families, hikers and pet owners may change routines — wearing protective clothing, avoiding dawn/dusk outings or keeping pets indoors during peak activity (Los Angeles Times; KESQ).
Practical applications: Land managers and outdoor groups should update safety plans, post tips at trailheads, train volunteers, ensure first-aid supplies and coordinate with hospitals on antivenom availability. Individuals should carry a charged phone and keep pets leashed (VVNG; CBS Los Angeles).
Reporting and staying informed
If you see a rattlesnake on public lands, report the sighting to local rangers or park staff so they can track patterns and warn other visitors. Check official USFS social media posts and local news outlets for updates before heading out (CBS Los Angeles; KESQ).
