Transitory Pine Forests
In northern Scotland some 4000 years ago, the range of Scots pine forests
first rapidly expanded and then retreated by about 80 kilometers during a 600-
year period. Although there is no pollen evidence for the existence of the forests,
stumps of fossil pine trees in peat attest to their presence. About 4400 years ago
the bog surfaces grew drier, and soil conditions, were conducive to rapid growth
of pines. Then around 4000 years ago another change occurred, causing the trees
to begin to die out. By 3800 years ago the northern region apparently had no
pine forests; the forests had returned to their original more southerly position,
where they are still found today. Gear and Huntley propose that the driving
forces for the rise and fall of the pine forests were shifting climates caused by
changes in atmospheric circulation; they note that other evidence from northern
Europe supports the notion that climate changed rapidly at that time. Although
the forests responded reasonably rapidly to climate changes, the speed of the
response – several hundred meters per year – is not one that would be fast
enough to keep pace with changes that could come as a result of greenhouse
warming.
