New growth forests are generally younger than 120 years and take up more CO2 than old growth forests. However, the amount of carbon stored in these forests is less than old growth forests due to their age.
What is an example of second-growth forest?
The forest in Stanley Park, Vancouver, British Columbia, Canada is generally considered to have second and third growth characteristics. This photo shows regeneration, a tree growing out of the stump of another tree that was felled in 1962 by the remnants of Typhoon Freda.
What is the difference between old-growth and second-growth forest?
In contrast to dense second-growth forest, old-growth forest has fewer and larger trees, many large snags and logs, and abundant understory plants, providing habitat for many more wildlife species and individuals of each species.
What is meant by old growth forests?
The DNR defines old growth forests as forests that have developed over a long period of time, essentially free from catastrophic disturbances. They contain large, old trees of long-lived species that are beyond traditional rotation (harvest) age.

What are new growth trees?
New growth wood, on the other hand, comes from trees that grew very quickly after a disturbance (such as a logging operation or a natural occurrence) cleared the surrounding area. These forests grow rapidly, and so the wood has looser rings and can be much softer and lighter.
Can old-growth forests regrow?
But we shouldn’t forget that trees can grow themselves.” It’s a lesson that looms large in a study led by Cook-Patton, published in Nature in 2020, that suggests that degraded forests, left to regrow naturally, may hold more carbon storage potential than previously thought.
Is an old-growth forest healthy?
Old forests containing ancient trees are essential ecosystems for life on earth. Mechanisms that happen both deep in the root systems and in the highest canopies ensure the viability of our planet.
Why are old-growth forests so important?
