Old-growth forests are ancient, complex ecosystems that have developed over centuries or millennia without significant disturbance from human activity. These forests are characterized by large, mature trees, rich biodiversity, unique microhabitats, and intricate ecological processes. A rich weave.

Old-growth forests should play a critical role in mitigating climate change. They are significant carbon sinks, storing vast amounts of carbon in their trees, vegetation, and soils. Indeed, old-growth forests are one of the few habitats on earth that can create new soil. But old-growth forests are disappearing fast.

The most biodiverse ecosystems on Earth have been destroyed at an alarming rate in recent human history. The loss of old-growth forests is a significant issue worldwide, with far-reaching consequences for the environment, biodiversity, climate stability, and human societies.

Kate Borduas, Master Naturalist, will examine when, where, why and how these vast losses occurred. From treating trees as a disposable commodity, climate disruption and the translocation of non-native species, trees in old-growth forests are being destroyed by multiple mechanisms with no end in sight.

Global conservation efforts will be needed if sustainable management and conservation of old-growth forests can provide lasting environmental, economic and social benefits.

And what can we do locally? Let’s explore that together.
