Growing Old-Growth

An old-growth redwood is huge. One of the largest living things to ever grace the planet. And their size isn’t just impressive, it’s important. In the Santa Cruz Mountains very few old-growth redwoods remain, but you’re helping to grow the old-growth of tomorrow, today. Together, we’re restoring redwood forests faster for the trees, for wildlife, for the fight against climate change, and for future generations.

A Stewardship Story: Return to Nature

Surviving since nearly the age of the dinosaurs, redwoods are resilient—but only 5% of them have survived the last century and a half. Human impacts have left redwood forests struggling to recover. Together, we are carefully caring for the redwood forests you protect, resetting their natural systems, and helping them return to nature. Take a peek behind the trees at how you have helped the redwood forests of the Santa Cruz mountains–some of the most biodiverse and threatened on Earth–this year.

Behind the Scenes: A Botanical Survey of Castle Rock Hollow

Among the hallmarks of healthy redwood forests are trees of varying ages growing and thriving together. Achieving this diversity of ages, or chronodiversity, can improve old-growth conditions, which leads to greater habitat diversity—two essential outcomes for redwoods to thrive in the Santa Cruz Mountains. Read on to learn about the importance of chronodiveristy in coast redwood forests.
