pioneer species
Ecological trailblazers arrive
A pioneer species is the first to colonize a barren or disturbed environment—lichens on bare rock, grasses after a wildfire, weeds in an abandoned lot.
These organisms are typically hardy, fast-growing, and tolerant of harsh conditions.
By modifying the environment, they make it possible for other species to establish themselves later: Fireweed is a classic pioneer species in burned forests.
