Local illegal marijuana grow sites cleaned up

Last fall efforts were made to clean up the left over chemicals and infrastructure of abandoned illegal marijuana grow sites in the Sierra National Forest. The death of several nocturnal weasels known as Pacific fisher, which were being studied by a group of University of California researchers in the area, lead to concern for the poisons left on these sites. Rodenticides used to keep young plants safe from rodents during the growing season are causing damage up and down the forest food chain.

The exercise included the High Sierra Volunteer Trail Crew, U.S. Forest Service, Ca. Fish & Wildlife and the National Guard. The work was made possible through a $25,000 grant from the local Chukchansi tribe. The grant was written by the Yosemite/Sequoia Resource Conservation District and SNAMP, the Sierra Nevada Adaptive Management Project’s wildlife and outreach teams,

The project took place in the Sierra National Forest in Madera County and the Sequoia National forest in Fresno County. Over six days the project hiked in and cleaned thirteen sites. They cleaned up abandoned campsites, propane containers, almost a hundred bags of trash, all the fertilizers, pesticides and rodenticides as well as almost 14 miles of drip line; to protect our wildlife and watersheds from future harm.

Several water reservoirs were dismantled that had been hand dug and used to collect water to mix growing chemicals in before being dispensed to the plants. These large pits have the potential to serve as a trap to wildlife or hikers, long after their intended use has passed. They can also release a flush of unwanted chemicals with the winter rains.

Thanks to the donation of personnel by partner agencies grant monies could be conservatively spent, allowing for multiple years of clean up efforts to continue. Anyone interested in being involved in these efforts in the future can contact the HSVTC at or Anne Lombardo at

ANR Green Blog: King Fire provides learning opportunities

Here is an excerpt from a recent ANR Green Blog post covering a workshop on the King Fire. Over a dozen UC Agriculture and Natural Resources (UC ANR) California Naturalists, fire ecology experts, wildlife biologists, resource managers, educators, and artists met at UC Berkeley's Blodgett Forest Research Station and the adjacent El Dorado National Forest April 23 and 24, and not one of them complained about the much-needed deluge of rain and intermittent hail that soaked the group. The weekend's ambitious goal? To dive deeply into a UC California Naturalist Program and California Fire Science Consortium advanced training workshop on the subject of wildfire effects on Sierran mixed conifer forests.

With the 2014 El Dorado National Forest's King Fire as a case study, a mix of lectures, field studies, art, field journaling techniques, and Native American story telling were used to examine land management practices that influence fire behavior and explore how the landscape recovers from fire. UC ANR Cooperative Extension Central Sierra's forestry advisor Susie Kocher and community education specialist Kim Ingram organized and facilitated the workshop.

Fall 2014 Newsletter: Vol. 7 No. 2 - IT Meeting Wrap up

We are in the midst of a very busy final year as each team continues to work on data analysis, integration and final report writing. Part of our SNAMP commitment is to provide opportunities for all stakeholders to participate in meetings where information is shared and ideas exchanged. In this vein, each Science Team participated in either an in-person meeting or webinar to inform SNAMP participants of their current research results and integration metrics. This newsletter is intended to provide one more link to the study and results, as well as to help better prepare participants for the Annual Meeting webinar on November 6, 2014.

Group works to reduce man made threat to Pacific fisher in the southern Sierra

Cleanup of the mess left behind by illegal marijuana grow sites in national forests around Bass Lake, California is about to begin. On November 5th, 6th and 7th , volunteers are invited to join the High Sierra Volunteer Trail Crew to clean up the trash, irrigation piping, growing chemicals and poisons left behind when grow sites are abandoned or raided by law enforcement. Excessive fertilizers, herbicides and pesticides used in large quantities to grow these crops are often left behind to leak into forested watersheds. Poisons include anti rodent pesticides that have silently killed a wide variety of animals in the forest during their use and can continue to over the months that follow. The work will involve a full day of effort and some hiking. If interested, contact Anne Lombardo at and bring a lunch as well as items for personal comfort: warmth, dry, water, sunscreen. The HSVTC will be providing safety equipment. This cleanup effort is made possible by a grant received by the Yosemite/Sequoia Resource Conservation District from the Chukchansi tribe as previously reported:
