## What the grant funds

Wildfire activity is increasing. Drought and prolonged, increased temperatures are creating conditions that allow wildfires to start earlier in the year, enable them to last longer, and make them more difficult to control. Increasingly intense wildfires and prolonged droughts then lead to an influx of invasive species that burn more easily than native vegetation and in turn propel still more extreme wildfire activity. As a result, wildfires are now occurring in places where they were previously extremely rare, with more land burning, on average, each year. This is leading to a year-round wildfire season, now referred to as a fire year, throughout the country. The frequency of large wildfires is also increasing, particularly near communities. The Infrastructure Investment and Jobs Act, also known as BIL, enacted in November 2021, provides funding to local governments to acquire slip-on tanker units to support wildland firefighters.
