Agri-environment schemes have been developed by the member states of the Eu
ropean Union over the last 10 years. Under Regulation 2078/92, the UK has s
upported English Nature in the implementation of a nature conservation sche
me for wet grazing land in southern England. This paper explores the differ
ent understandings of nature. held by farmers and conservationists who are
participating in the Wildlife Enhancement Scheme, by drawing on qualitative
research completed between 1993 and 1995. Through the application of actor
network theory, the analysis compares the role and identity ascribed to fa
rmers by conservationists with the identity that farmers' construct of them
selves. The former construct farmers as technicians, ignorant of the workin
gs of nature, whereas the farmers see themselves as 'natural conservationis
ts'. The paper explores how nature is translated differently in the worlds
of conservation science and agriculture. In the final part of the paper, di
scussion focuses on the management. of the wetland ditches when these sets
of translations come together. It reveals that the rigid, scientific prescr
iptions for management of the conservation value of the ditches are conside
rably at odds with the more flexible and sensitive practices of farmers the
mselves. (C) 2000 Elsevier Science B.V. All rights reserved.
