Forests provide different benefits at different stages of maturity.

Younger trees capture carbon at a greater rate than mature forests. Some animals thrive best in established forests, while others do best in younger ones. Some species even prefer areas that have been recently harvested or burned. The key to making our forests the best they can be is helping to maintain a healthy balance of different tree species and ages across the province.

Stage One:
Young Forest

Where sections of older forest have burned or been harvested, a young forest has room to emerge. In the case of harvesting, Alberta’s forestry companies are required to replant the area with a similar mix of trees and help the new forest establish itself. Young forests are open enough for sun-loving plants to grow in, and those plants are a food source for iconic Alberta wildlife.

Stage Two:
Growing Forest

The middle stage of a forest’s life is the longest – over the course of this stage, the forest continues to mature and evolve. Trees reach the prime of their life, and the mixture of cover and open space attracts a new host of plants and animals. A complex natural ecosystem emerges, and the forest becomes self-sustaining.

Stage Three:
Mature Forest

The trees in mature boreal forests have reached full size and are densely packed together. Large amounts of carbon are stored in mature forests, and they’re key to the survival of wildlife species like caribou. Trees at this stage start to be more susceptible to fire, disease and insect infestations, though, and most Alberta trees have a maximum lifespan of 150 years under ideal conditions. Without strategic forest management, historical fire patterns show that most Alberta forests would burn every 50-100 years.

Young Forest: Trees

Helping Conifers Grow

Deciduous trees grow back very quickly on their own – they don’t need to be replanted. In fact, these trees can easily dominate a young forest, taking up the available sun and space.

Coniferous trees don’t come back as easily by themselves, and they grow much more slowly. Replanting conifers and helping the seedlings survive in their new home is part of what forestry companies do in the 14 years after harvest.

Take a look around. What do you see? If you answered trees, your instincts are back on track. But, you know, it’s the strategic mix of trees here that really deserves mentioning. Sure, they grow naturally. But some grow faster than others. Like the trembling aspen of the deciduous family. Deciduous. That’s fun to say. De-ci-duous. De-ci-duous. Right. Trembling aspen don’t need replanting. They just show up. They’re like “hey, are you guys growing a forest? Cool, we’ll be there.” They weren’t even invited. T B totally H, trembling aspen can easily dominate a young forest taking up the available sun, space and veggie dip. It’s for everyone, aspen. Coniferous trees. CONIF! to its friends. Much like me in the A.M. they need a bit more coaxing. By comparison, they’re late bloomers. Forestry companies play a vital role in the survival of conifer seedlings—those sweet babies. And it’s not like an overnight babysitting gig. Those foresters look after the conifer younglings for at least 14 years. After that, the conifers get their learner’s permits and need a bit more space. And didn’t we all at that age. You go trees. You go.

In 2020 alone, Alberta forest companies planted 87 million trees.
