Soils in old-growth treetops can store more carbon than soils under our feet

Soils in old-growth treetops can store more carbon than soils under our feet

New research reveals a previously underappreciated way old-growth forests have been recycling and storing carbon: treetop soils. Branches in forest canopies can hold caches of soil that may store substantially more carbon than soils on the ground beneath them, and scientists are just beginning to understand how much carbon canopy soils -- which exist on every continent except Antarctica -- could store.
