Temperate Forests

Unlike tropical deforestation, most temperate and boreal forest loss is temporary — logging and wildfire that regrows — but the growing share driven by fire rather than harvest signals a changing, less predictable forest system.

Overview

Temperate forests span regions with distinct seasons across North America, Europe, and East Asia, supporting deciduous and mixed forest ecosystems that differ ecologically from both tropical and boreal forest. Unlike tropical deforestation, most temperate forest loss is not permanent.

Established fact

Temperate and boreal forests together experienced 218 million hectares of gross tree cover loss since 2000, but approximately 98% of this is linked to temporary factors — primarily logging and wildfire — where tree cover is expected to regrow, in clear contrast to the largely permanent agricultural conversion driving tropical deforestation.

Regional Drivers

RussiaWildfire accounts for approximately 63% of tree cover loss across Russia and the Asian mainland's temperate and boreal forest.
N. AmericaWildfire and logging account for roughly 52% and 43% of North American temperate/boreal tree cover loss, respectively.

Wildlife Considerations

Because most temperate forest disturbance is followed by regrowth, the ecological impact on wildlife depends heavily on regrowth timescales relative to species' life cycles — old-growth-dependent species can be affected for decades even when the forest itself is classified as "recovering" in satellite tree-cover data.

Pressures

Wildfire intensificationLarger and more frequent wildfires, linked to warming and drying trends, are shifting temperate forest disturbance regimes away from historical baselines in parts of North America and Russia.
Commercial loggingTimber harvest remains a major, well-documented driver of temporary tree cover loss, particularly across managed forest landscapes in North America and parts of Europe.
Old-growth scarcityEven where forest cover regrows after disturbance, old-growth structural characteristics — large trees, standing deadwood, complex canopy layers — take many decades to redevelop, limiting suitable habitat for old-growth-dependent species in the interim.

Uncertainty & Evidence Gaps

Satellite-based tree cover loss data does not by itself distinguish between clearcut-and-replant forestry, natural regrowth after fire, and permanent conversion — the "temporary vs. permanent" classification relies on additional land-use modeling that carries its own uncertainty, particularly in mixed-use landscapes.
