Tree Mortality

Since 2012, record drought and record temperatures, have weakened trees throughout California, resulting in millions of acres of failing forestland that then become vulnerable to disease and infestation. Infestation, such as those caused by native bark beetles, have caused tree mortality of epidemic proportions.

The scale of tree mortality in California contributes to significantly increased wildfire risks, and presents life safety risks due to falling trees that can injure or kill people.

Due to these increased risks, California and Tulare County have proclaimed states of emergency for tree mortality.

On September 7, 2016 the USFS approved Tulare County's removal plan.  The attached memo is a sign-off on permission for similar removals along an estimated 60 miles of county roads:  Arterial Roads Decision Letter.



On October 6, 2015, the County of Tulare proclaimed a local emergency due to tree mortality, which increases threats to public health and safety, including fire, falling tree/debris, and air quality hazards, and requested that the Governor proclaim a State of Emergency and that the Governor request a Presidential Declaration of Emergency or Major Disaster.

Proclamation of Existence of Local Emergency


On October 10, 2015, Governor Edmund G. Brown Jr. proclaimed a State of Emergency and sought federal action to help mobilize additional resources for the safe removal of dead and dying trees. This proclamation builds on Governor Brown's April, 2014 Executive Order to redouble the state's drought response, which includes provisions to expedite the removal of dead and dying hazardous trees. Governor Brown's proclamation also calls for state agencies to take several actions to enable removal of hazard trees.

Guidelines for High Hazard Zone Tree Removal

The State's Tree Mortality Task Force, Regulations Working Group, has released its final Guidelines for High Hazard Zone Tree Removal to assist in the implementation of Governor Brown's October 30, 2015 Emergency Proclamation for dead/dying tree removal in High Hazard Zones, as identified by CAL FIRE's Tree Mortality Viewer.

Right of Entry Process

If dead or dying trees are located on private property adjacent to the County’s right of way, but present an immediate threat to public health and safety (for instance, they threaten infrastructure because they are leaning over the right-of-way), the County may attempt to remove the trees - time and resources permitting. Before the County will remove any trees originating from private property, the County will request that property owners sign a “Right-of-Entry” agreement form, which contains insurance, indemnification and release provisions that meets Cal OES/ California Disaster Assistance Act requirements for reimbursable debris removal work.
