Danger of marijuana cultivation on the Pacific Crest Trail

While only a fraction of our public lands are affected by illegal marijuana cultivation, the Pacific Crest Trail Association, Forest Service and our other agency partners believe that safety risks are real and everyone should be informed about them. Dangerous marijuana cultivation sites may be present on the Pacific Crest Trail corridor, especially in Southern California, but also all along the trail.

The safety of Pacific Crest Trail visitors, volunteers and employees is our top priority. Marijuana cultivation occurs on some public land and it’s important for everyone to be aware of their surroundings.

The disturbances that marijuana cultivation makes on natural resources causes extensive and long-term damage to ecosystems and impacts the supplies of public drinking water for hundreds of miles. Growers clear native vegetation before planting and sometimes use miles of black plastic tubing to transport large volumes of water from creeks that are often dammed for irrigation. The use of banned herbicides and pesticides by marijuana growers kill wildlife and competing vegetation. This loss of vegetation allows rainwater to erode the soil and wash poisons, human waste, and trash from the grow sites into streams and rivers.

Here are some clues that you may have come across a marijuana cultivation site:

  • Sometimes marijuana smells like a skunk on hot days.
  • Hoses or drip lines located in unusual or unexpected places.
  • A well-used trail where there shouldn’t be one.
  • People standing along roads without vehicles present, or in areas where loitering appears unusual.
  • Grow sites are usually found in isolated locations, in rough steep terrain.
  • Camps containing cooking and sleeping areas with food, fertilizer, weapons, garbage, rat poison, and/or dead animals.
  • Small propane bottles, which are used to avoid the detection of wood smoke.
  • Individuals armed with rifles out of hunting season.

As soon as you become aware that you have come upon a cultivation site, back out immediately. Never engage the growers as these are extremely dangerous people. If you can identify a landmark or record a GPS coordinate, that’s very helpful. The growers may be present and may or may not know that you have found their grow site.

Get to a safe place and report as much detail about the location and incident as you can recall to any uniformed land agency employee or to the local law enforcement agency. Please also notify the PCTA. Leave the way you came in, and make as little noise as possible.
