They reviewed 17 years’ worth of studies on primary forests, which they took to include any tracts that were “primeval, virgin, near‐virgin, old‐growth, [or] long‐untouched.”.
If the goal is to buoy species that are struggling to find habitat, he says, one tactic might be creating proxies for natural deadwood, and carving cavities into trees to give bats, woodpeckers, and other birds a spot to nest. This has led to much controversy between logging companies and environmental groups. A team of researchers, led by Francesco Maria Sabatini of Berlin’s Humboldt‐Universität, recently set out to map exactly where those oldest, least-disturbed forests are, and how many of them are left. [26] However, evidence from analysis of carbon stored above ground and in the soil has shown old-growth forests are more productive at storing carbon than younger forests.

They are thick, tall, and deep—so much so that the young duo could wander them for days.
Text taken from Global Forest Resources Assessment 2020 Key findings, FAO, FAO. Since focusing on utterly untrammeled forest would have yielded a very brief list, the team took a broader view. [4] In Australia, eucalypt trees rarely exceed 350 years of age due to frequent fire disturbance.[5].
Old-growth forests in this region have now been placed inside national parks. This would be hard to believe in Europe," explains Humboldt University scientist Francesco Maria Sabatini, lead author of the study. For example, this potential is particularly high in the Pacific Northwest where forests are relatively productive, trees live a long time, decomposition is relatively slow, and fires are infrequent. Old-growth forest serves as a reservoir for species which cannot thrive or easily regenerate in younger forest, so can be used as a baseline for research. In British Columbia, Canada, old growth is defined as 120 to 140 years of age in the interior of the province where fire is a frequent and natural occurrence.
The best approach will vary by place and conditions. Perhaps the “best way to express one’s love to these wild areas,” he says, “is to keep them wild.”.
