Tree Mortality
Tuolumne County Tree Mortality

Tuolumne County has thousands of dead and dying trees that are threatening public safety and infrastructure. The County is taking action to work towards mitigating hazardous dead trees in the following ways:

•On September 18, 2015 the Board of Supervisors proclaimed a Local State of Emergency due to pervasive tree mortality. The most current declaration can be viewed here.
•On October 30, 2015 Governor Brown issued a State of Emergency proclamation, which can be read here. This proclamation recognizes and addresses the need for the removal of dead and dying trees throughout the State and authorized California Disaster Assistant Act (CDAA) funding which provides 75% reimbursement for all eligible costs related to removal of hazard trees that threaten public infrastructure.

•County, City and Special Districts are eligible for reimbursement through CDAA.

•The Governor's Executive Orders allow County, City and Special Districts the flexibility to remove dead and dying trees that threaten public infrastructure.  Some of these trees may be on private property.  The County will send out Right of Entry permits to homeowners who may have dead trees on their property that could potentially impact County maintained roads or County maintained structures. Once the homeowner signs and returns the right of entry permit, they will be entered into a secure database which notifies the contractor which properties they can access.

•Tuolumne County received preliminary approval for CDAA on November 18, 2015.

•CDAA does not provide assistance to private property owners or businesses.
Tree Mortality Task Force

A Tree Mortality Task Force was assembled to develop a response plan for removing hazard trees. The goal of the Tuolumne County Tree Mortality Task Force is to collaborate with local, as well as private, and public partners to identify and remove dead and dying trees which threaten public safety and infrastructure (power lines, water systems, roads/highways, communication lines, etc.). County staff continue to working towards mitigating the threat of dead and dying trees with our partners. The first step is to identify and prioritize areas where dead trees need to be removed to protect public infrastructure.

Supervisor Brennan, Supervisor Hanvelt, County OES Coordinator Tracie Riggs and the County of Tuolumne Tree Mortality Project Manager, Mike Albrecht, are all members of the Governor's Tree Mortality Task Force. This task force meets on a monthly basis and provides a forum for coordination and information sharing among local, state, federal, private and non-profit agencies in an effort to ensure public safety and continuity of essential services from the threat of tree mortality across the State of California.

This page will be updated as new information becomes available.

Quick Links and FAQ's (on the right hand side of this page) are resources made available to you from the County and its partner agencies. If you would like more information, please contact us and we will be glad to assist.
CAL FIRE has created a 4 minute long video on the bark beetle/tree mortality epidemic in California.

California State Association of Counties (CSAC) has created a video that details how devastating the tree mortality issue is becoming. Additionally, CSAC President Richard Forster has written a blog that accompanies the video and can be read here.

Tree Mortality Coordination Efforts

There are a number of tree removal efforts taking place in Tuolumne County and will continue as new dead trees are identified. Below is an outline of the various agencies and companies removing trees around Tuolumne County.

1. PG&E: PG&E contracts with ACRT to mark trees that threaten PG&E power lines. PG&E also contracts with various tree removal companies such as, Mountain Enterprises, Utility Tree Service, and Phillips and Jordan. Phillips and Jordan is running PG&E's debris removal program, which homeowners can participate in by calling 1-800-743-5000 .

2. County of Tuolumne: The County is marking and removing trees that can fall onto or over a County maintained road, or County maintained structure. The County contracts with Certified Arborists and Registered Professional Foresters to mark trees that meet CDAA qualifications. After the trees are marked, the County then contracts with Licensed Timber Operators or D-49 Tree Service Contractors to fell the tree. CAL FIRE is providing crews from Baseline Conservation Camp to chip the slash and debris.

3. Caltrans: Caltrans is removing trees that threaten state highways, such as Highway 108, Highway 120, Highway 49, etc. Currently, Caltrans is removing trees on Highway 108 from Soulsbyville to Strawberry. Caltrans has contracted with SMCI to remove and process the trees. Their wood sort yard is located on Highway 108 across from the Lyons Reservoir entrance.

4. Tuolumne Utilities District: TUD is removing trees that threaten their flume, ditch, and water treatment infrastructure. TUD has marked those hazard trees that qualify for their program and will begin the tree removal process soon.

5. Twain Harte Community Services District: THCSD has identified dead trees that have the potential to damage their infrastructure (water, sewer, structures, etc). They will soon begin the tree marking process once a certified arborist or forester has been selected.


NOTE: The contractor will only enter your property if a signed Right of Entry Permit was submitted to the Tuolumne County Office of Emergency Services.

All logs removed have been taken to the County Wood Sort Yard. From there, the wood will be chipped by Ultrapower, taken to California Wood Shavings, and/or to Sierra Pacific Industries.

Tuolumne County Wood Sort Yard 


In response to the large volume of wood requiring disposal, the County has opened a wood sort yard that will allow logs of all sizes to be dropped off, free of charge. The wood sort yard is in close proximity to Pacific Ultrapower, which gives them the ability to chip wood on-site to be used as fuel for power production. This is an environmentally conscious and cost effective solution for wood disposal. Additionally, some wood may be sent to American Wood Fibers and Sierra Pacific Industries, depending on condition and marketability. The County is not providing payment for wood dropped off at the sort yard. 


The wood sort yard is located off highway 120 and Enterprise Drive. Signage to the wood yard will be on Enterprise Drive. Hours of operation are: Monday-Friday, 7 a.m. to 5 p.m. 

•From Sonora: Take highway 108 to the highway 120 exit at Yosemite Junction. Continue on highway 120 for approximately 1.67 miles. Turn right on Enterprise Drive. The wood sort yard is on the right hand side, just before the gate to Ultrapower. 

•From Groveland: Take highway 120 approximately 13 miles and turn left on Enterprise Drive. The wood sort yard is on the right hand side, just before the gate to Ultrapower. 

Please note: NO dumping or wood cutting will be allowed. The wood yard will accept logs of any size and length, but will not take slash, pine needles, stumps, or debris. 

At this time, slash may be disposed of for a fee at these commercial sites: 

•Cal Sierra Earth Resource Facility

CAL FIRE SRA Tree Mortality Grants

In October 2016, the County of Tuolumne submitted 15 grants to CAL FIRE for the removal of dead and dying trees, totaling $3 million.  We are please to announce that CAL FIRE selected 12 of those grants for an award amount of $2.4 million.  Similar to the CDAA program, the County will be sending out Right of Entry Permits to homeowners once the projects have been fully developed. The project areas have been broken into 10 Zones as depicted in this map. The specific projects and corresponding Zones are detailed below:

  1.  Removal of dead and dying trees within 300 ft of a private residence (Zone 1, 2, 3, 4, 5, 7, 8, 10) has been allocated approximately $1.67 million.  To stretch these funds as much as possible, the homeowner will be responsible for a portion of the cost to remove these trees.  The County worked with Housing division to determine a pay scale based on income and number of people in the home.  The cost match chart can be viewed here.
  2. Zone Removal of dead and dying trees adjacent to County Service Area (CSA) roads (Zone 1, 3, 4, 10) has been allocated $800,000.  CSA roads are those that are non-County maintained; however, the County does have a contractual obligation to provide maintenance.  The homeowner will not be responsible for a cost-match for the removal of these trees.

PG&E Debris Removal Program

PG&E has contracted with Phillips and Jordan, a large scale disaster clean-up company, to manage their debris removal program. PG&E will be offering residents the option to have their trees and debris removed, if they were cut down by PG&E.

For more information, you can contact PG&E at 1-800-743-5000 or read this press release for program details.

Community Information Lines

The County of Tuolumne has opened Community Information lines to assist residents with their questions regarding hazard tree removal. The lines will be staffed by local volunteers who have received training to answer tree mortality questions.  Please understand that the volunteers do their best to answer questions regarding the County's tree removal process; however, they cannot answer all questions regarding what other agencies or counties tree removal process.  The lines are staffed Monday-Thursday.  You can contact the Community Information Line at (209) 533-6394. Due to high volume of calls it may be necessary to leave a message.  The volunteers will return all missed calls as soon as possible.

Information for Private Forest Landowners

The US Department of Agriculture Natural Resource Conservation Service has released federal funding to assist in the removal of trees on private forestlands. For more information please call 209-223-6535. The press release can be viewed here.
