Historical Forest Carbon Balance 1855-1995
Through processes of respiration and through the decay of organic matter or burning of biomass, forests release carbon. A carbon ‘sink’ is formed in the forest when the uptake of carbon is higher than the release. The co...

Forests Regulate Groundwater Level
Forests can regulate groundwater levels and increase drainage of soils where the water table is close to the surface. If there are salts in the upper soil layers, then removal of forests can result in raised groundw...
