The United States is home to a very diverse number of climates. Across the nation, trees number 300 billion and come in many shapes and sizes. In some states, such as Maine or New Hampshire, trees make up over 80% of the state. Regardless of the type, all trees suffer from the threat of deforestation.

One of the major factors in a dense forest is the threat of invasive pests. It is estimated that 15% of the nation’s 300 billion trees are impacted each year by native and non-native insects. This equates to a staggering $40 billion in damage every single year. Factors like unsustainable logging and poor land management practices reduce the breadth of forests, which forces the pests into higher densities.

Another major factor is the spread of wildfires. The most recent and major example being the 2024-2025 California wildfires. In the first 15 days, an estimated 43,000 acres burned and a total of over $135 billion in estimated damage for the entirety of the wildfires.

The best way to prevent both pests and wildfires is by decreasing the density of trees. However, it’s important to make sure these trees are done correctly. Companies like Tree Service Expert lend professionals who have both knowledge and experience of the tools needed for the job. To make sure it’s done right, it’s best to leave it to a professional.
