I often go on long country walks in Berkhamstead in Hertfordshire and the Epping Forrest in Essex in summer time. Nearly all UK forests are managed and over the years I have come to a know a few hikers who are well versed in forestry. Since I have the irritating habit of never accepting any number without checking, let us do some arithmetic.
In the UK normal tree spacing for reforestation is between 8 x8 and 10 x 10 feet; that is 8 feet between each tree and 8 feet between each row. This gives roughly 400 to 600 trees per acre; let us say about 500 per acre. For wild life spacing is more and the number of trees could be as low as 200 per acre. Remember that despite being looked after, not all the saplings survive to mature trees. Survival rate is different for reach species, however an average of 90% is good.
In simple terms, 1-million trees need about 2000 acres. 350,000 hectares are equal 864, 850 acres therefore number of trees planted comes to about 432-million. Understand that maximum number of saplings planted for reforestation is about 700 per acre; even then total number of trees should be about 600-million. I would say actual figure is probably 500-million trees.
The figure of 1-billion is obviously an exaggeration but even if KPK gov’t successfully managed to grow 500-million trees in 2 –years; it is a fantastic achievement.
Hats off to PTI & KPK gov’t. Keep up the good work.
