12 pages, Little comparative work has been conducted on the environmental belief systems and behaviours of conventional and organic farmers, especially in relation to farming culture, the environment and lowland farmland avifauna. Adopting a modified behavioural approach, this paper analyses the ways in which the environmental attitudes and understandings of farmers in central-southern England influence their behaviour. Key stakeholder and farmer interviews and a focus group discussion showed how some organic farmers tend to have small, diverse and untidy farms, ecocentric attitudes and a non-exploitative approach towards farming which includes an appreciation of farmland birds. This often contrasts with the tidy, well-organised conventional farmers with their larger, specialised farms, technocentric attitudes and exploitative view of nature, frequently related to creating pheasant cover and the belief that corvids and birds of prey are vermin and should therefore be eradicated. However, these attitudes and behaviours may not necessarily be representative of any differences between those farmers loosely labelled as ‘organic’ and ‘conventional’.
