Fun, weird, helpful, or little known fact
When fireweed emerges roadside on the Pass, I know the summer wildflower season has officially entered its second half. As a result, lovely as it is, it brings on a mild panic attack.
Fireweed is an important colonizer following vegetation disturbances (like fire or avalanche or road-building) in temperate climates all over the world. Fireweed enters a disturbed community and rapidly becomes abundant. It may achieve a peak in dominance within 2 to 3 years, but then declines if it does not receive enough sunlight or gets crowded out by other species.
