TREX events have been hosted in states including Oregon, California, Montana, Maine, Nebraska, and South Carolina. While not shown on the map below, TREX events have also been held internationally in countries such as Mexico and Portugal.

Most TREX events take place in the spring or fall, when conditions are more likely to be good for safe and effective prescribed burning. TREX events that are accepting applications can be found under the “Prescribed Fire Training Exchanges (TREX) & Cooperative Burning” category on the News & Events page.
