The remoteness and small size of old-growth boreal trees should not make us forget their high ecological importance and the many threats they face.
In North America, log driving is thought to have stopped by the end of the 20th century, with the exception of British Columbia, where it is still practised on a small scale.

Rising temperatures mean longer, earlier pollen seasons, but a bigger problem is what more carbon dioxide will do to the amount of pollen being released.
Eventually weather, pests and disease will take their toll, but the story doesn’t end there.

Red tingle forests in south-western Australia have the lowest fire risk when they’ve not been subjected to prescribed burning. New research explains why
Native wildflowers, such as these Dutchman’s breeches (Dicentra cucullaria) that bloom early in spring are losing access to sunlight as trees leaf out earlier.

Many beloved wildflowers bloom in early spring, while trees are still bare and the flowers have access to sunlight. Climate change is throwing trees and wildflowers out of sync.

Protecting old and mature trees is the simplest and least expensive way to pull carbon out of the atmosphere – but proposed logging projects threaten mature stands across the US.
Over 50 fire ecologists across the Western U.S. took an unprecedented look at how forests in thousands of locations are recovering from fire in a changing climate. The results were alarming.
More of us now own indoor plants.
