Sample text

Source: Watson (1981) required by different woodland species. Many woodland butterflies like sunny areas to fly in and prefer woods with plenty of rides and clearings. Other plant-eating insects include the beetles and true bugs. 4). As well as the plant-eating species there are invertebrate predators that specialise in hunting for food on trees. 10). Other invertebrate predators or parasites are specialists living in very precise places, like the spider Drapetisca socialis which lives at the bases of beech trees or some of the rot hole breeding flies which need exactly the right kind of rot.

When an existing area of woodland is cleared of its trees or an area of open land which has been treeless for many years is left, trees usually colonise in the same order, early successional trees and then late successional ones. This secondary succession can occur over a large area, for example, in Britain when a heathland is left ungrazed or uncut. It can also take place on a much smaller scale within woodland when some sort of disturbance causes a gap in the canopy. If a single tree falls, the gap may not be very large and the remaining trees will just extend their branches to make use of the extra light.

6 : LOBARIA SPECIES Lichens consist of two different organisms in a symbiotic relationship. The first is an alga, which is able to photosynthesise and the second is a fungus. The resultant structures have no true roots and no protective cuticle so they grow when conditions are wet, but dry up when the weather is dry and sunny. Hence they grow best in the wetter west of Britain. Many different lichen species grow on trees and some are quite difficult to identify. They range from tiny encrusting forms, hardly recognisable as lichens, on the trunks of the trees to extensive mats on horizontal branches.
