For many this is a contradiction in terms. Farmers make use of Nature. They want to achieve maximum yields in their fields. Therefore they protect their crops from competing weeds, diseases and pests. The changes made to these natural habitats have driven many species, particularly those inhabiting open field country, into ecological niches.
Ecosystems are living communities.
In densely populated areas they have been created mainly by humans. This applies to both our heathland and our forests. And most of these were established by humans, though more recently. In Central Europe, for example, more than two thirds of the land area is used for agriculture and forestry. The flora and fauna have adapted to manmade landscapes.
