What is the biggest natural threat to redwoods?
Climate change, and its current and projected interactions with these stressors, jeopardizes the redwoods' ability to survive and thrive into the future.
Why are giant redwoods only in California?
Giant Redwoods As its nickname suggests, giant or coastal redwoods thrive in the moist, humid climate of the Northern California coast, where marine fog delivers precise conditions necessary for its growth. The fog adds moisture to the soil and helps trap it there by lowering the rate of evaporation.
When did they stop cutting down redwoods?
Many of California's old-growth redwoods — the world's tallest living things that can grow to more than 300 feet high and live 2,000 years — were cut down between the 1800s and the 1970s for decks, paneling, and even fence posts and railroad ties. Modern environmental laws and the creation of public parks ended it.
What is mysterious about redwoods?
Redwoods are so huge, a single tree itself can be habitat for an incredible number of species. When redwoods shed their foliage, much of it accumulates in the branches and decomposes to become soil, or canopy soil, where other species of plant seeds and fungi spores can sprout.
Why did redwoods evolve to be so tall?
Over the hundreds or thousands of years that a redwood may live, even moderate growth adds up. The evolutionary driver of bigness in redwoods may be the advantage in being good at survival. Or it may be simply be that being taller means better access to sunlight in the dark forest.
