29. Conclusions from the Previous Pages

44. Climate change notes

OLD PARADIGM     The current landscape consists of degraded ecosystems, largely through past and present human action. Hence ‘habitat restoration’ is a key activity.


NEW PARADIGM     The landscape of northern and western Scotland contains one of the most natural vegetation patterns in Europe with, for example, the current rarity of woodland in many localities being a key biodiversity feature. Hence the concept of ‘habitat restoration’ loses its meaning.
