Intensification of agricultural land-use was shown to be the key reason behind declines in wildlife
species associated with farmland. I looked at scenarios of agricultural development across the Baltic states of
Estonia, Latvia and Lithuania, and the ways they are seen to affect farmed environments as a habitat of
farmland bird species. Community richness and abundance of many farmland bird species were positively
related to the number of non-cropped elements within farmland, the local mixture of annual crop and grass
fields, and the variety of field types. The above positive associations were strongest in open landscapes.
There was a clear indication that the more intensively farmed areas across the region provided habitat for
fewer bird species and individuals. The difference could partly be explained by the more heterogeneous
landscape and field areas in the latter. Within homogenous arable fields intensification of field management
was reflected in a tangible decrease in farmland bird abundance, especially in species in need of edge
structures.
Based on the interviews in Estonia and Finland I explored farmers’ interest in and knowledge of
farmland wildlife, their understanding of the concept of biodiversity, and awareness of the potential causes
behind declines of farmland birds. Many farmers viewed biodiversity from a narrow perspective often
excluding species directly related to farming. In Finland farmers expressed concern about the decline in
common farmland species, but Estonian farmers did not, which might be related to the fact that these species
are still very common. In both countries farmers rated intensification of agriculture as the major driving
force behind farmland bird declines. The expressed interest in wildlife positively correlated with willingness
to undertake wildlife-friendly measures. Only farmers with agri-environment contracts targeted specifically
at biodiversity enhancement were more knowledgeable about practical on-farm activities favouring wildlife,
and were more willing to employ them that the rest.
The results suggest that, by contributing to simplification of the farmland structure, homogenisation
of crops, and increase in intensity of field use EU agricultural policies will have a detrimental effect on
farmland bird populations in Eastern Europe. Farmers are on the whole positive to the idea of supporting
wildlife in the fields, and are concerned about its decline, but they require payments to offset their income
loss and extra work. Biodiversity conservation should be better integrated into the agri-environment
programmes if it to serve as awareness tool for farmers. I argue that with a foreseen tripling of cereal yields
across the region, the EU Council’s Göteborg target of slowing biodiversity decline by 2010 may not be
realistic unless considerable improvements are made into the EU agricultural policy for the region.
