Reward Grows to $147,000 in Lake Tahoe Tree Poisoning Investigation

A $147,000 reward has been offered for information about the alleged poisoning of dozens of trees at a Lake Tahoe beach. What has happened to the trees, and who is offering the reward? Read on for the details of this mystery.

At Least 28 Trees Poisoned at Lake Tahoe Beach

Someone has been poisoning 28 pine trees at a residents-only Lake Tahoe beach. While investigators have not identified a concrete motive, they believe that the suspects might be trying to kill the trees so that they have a better view of the waterfront.

The reported attacks have happened at Burnt Cedar Beach in Incline Village, Nevada. The affluent community is nestled along the north shore of the lake that straddles the California and Nevada border. According to the Incline Village General Improvement District, staff identified four poisoned trees on May 26, two more on July 23, and another ten sick trees on August 2.

The attacks on the trees have been happening for about four years. Authorities believe that the perpetrators are boring holes into the trunks and slowly poisoning the ground that surrounds the trees' roots.

The district said that the slow and deliberate killing is designed to poison the trees from above and at root level. The agency said that the holes have been injected with what they believe to be copper sulfate, a harmful chemical that can disrupt the movement of water and nutrients throughout the tree. The suspect then allegedly poured diesel fuel on the ground around the tree trunk, contaminating the soil and roots.

Trees that have distinguished the landscape of this forested region for centuries are now beginning to give out and fall. The district said that 28 trees have been targeted thus far, amounting to over $300,000 in damage.

During an August 12 board meeting, Incline Village General Improvement District General Manager Robert Harrison said that "It was an act of vandalism against the entire community. This is a community asset that we have here and, frankly, we are really angry about what happened at that site.”
