Читать книгу The Wildlife-friendly Garden - Michael Chinery - Страница 10

Older nature books commonly listed the gardener’s friends and foes, but now that we know a lot more about the life histories of the animals and know that everything has its place in nature’s complex web, it is not so easy to pigeonhole them in this way. For example, a centipede eating a harmful slug might be regarded as a friend, but you might change your opinion on discovering that a centipede’s diet consists mainly of other centipedes. Nevertheless, it is still possible to recognize some positively useful creatures – friends – which should be welcomed into the garden and some without which our gardens would be better off. These are the pests that eat our crops and spread diseases and they must be discouraged if not actually destroyed.

FRIEND OR FOE?

This simple, although not infallible, rule of thumb may help you to decide which are the goodies and which are the not-so-good. Fast-moving garden creatures are generally predators and on your side, whereas slow-moving creatures tend to be herbivores and are thus often harmful in the garden.
