Abstract
Ecological biogeography, defined here as the ecological study of man‐managed communities, is essentially experimental: practical work therefore should play an important role in teaching this specialism. In Britain, lowland agricultural land has attracted little ecological investigation but falls within the scope of geography; characteristics of the farmland habitat combine to make it especially suitable for biogeographical field study. Field work, varying in form from day visits to projects spanning several years, may illustrate many biogeographical concepts introduced in lectures.
