One of the ecologist’s particular roles in this connection has been to identify the factors which impede the growth of plants on various industrial

With road and rail systems the main biological problems relate to encroachment by vegetation and the possibility of collisions with animals. Aircraft are particularly vulnerable to in-flight collisions with birds and this ‘bird-strike’ problem is no

The hazards of poor sanitation are thereby added to the traditional threats from tropical diseases. Many of the expanding towns also have food supply problems because the surrounding country has

The problem tends to be aggravated by the migration of farmers and their families into the towns and by inadequate arrangements for storing food and transporting it from rural areas.

Thus, whilst a forest managed for timber production can accommodate a wide range of recreations within its boundaries, this is not the case with a lowland farm. Farmland, however, may form an essential background to those sight-seeing activities which involve the aesthetic appreciation of landscape.
