Planting a sapling offers only the potential for long-term storage of carbon:
Mature hardwood trees require approximately 20m spacing (300m²) while saplings are planted as close as 1.5m centres (2.25m²). This means that only 1 in 140 planted saplings will reach maturity in 80 years time.
Global warming requires immediate solutions as there are genuine concerns that action is already too late.
Carbon capture is very inefficient when a tree is very young or old.
It is unlikely that trees such as beech will survive for more than two or three decades given the current rate of global warming.
Pollarding or coppicing is a much more efficient method of carbon capture, as the original root system can quickly build up new limbs that can again be used to provide new beams.
