They do so fast and dramatically after fire and, it’s suspected, more slowly following other deaths. This gives them their reputation as a “pioneer species,” for the way they colonize otherwise ravaged. Mature trees die, and new stems sprout. That underground root system is also behind aspen’s curious “cloning” process. The outbreak began in 1996 and today 1.5 million acres are infected.
