Tree Mortality Update

Drought and bark beetle infestation has killed thousands of Twain Harte's majestic pine trees over the last two years. As we mourn the change of our beautiful landscape, we also become aware of the potential dangers that tree mortality brings to our community. Many dead trees have already been removed, but the number of dead trees seems to outpace removal. It seems like a problem too large to tackle, but our residents and local agencies are banding together to help keep our community safe.

What is our District Doing?

The District received California Disaster Assistance Act (CDAA) funding to pay for 75% of the costs to remove dead and dying trees that threaten at-risk water and sewer infrastructure.  We are pleased to report that we removed 475 trees in the District, protecting our facilities and the community.

With the good winter weather, we're hoping tree mortality will slow and we will not have to remove any more dead trees.

What are Other Agencies Doing?

Pacific Gas & Electric (PG&E)

PG&E has removed more than 80,000 trees in Tuolumne County and continues to mark and remove trees that threaten powerlines at a fast rate.  PG&E has also implemented a debris management program to help remove eligible logs after falling.
