This chapter explores the degree to which organic farming, and specifically organic dairy systems, has a part to play in biodiversity conservation in the land sparing-land sharing continuum of approaches. The chapter begins with a brief review of evidence for organic farming being nature-friendly, and the proposed mechanisms behind the relationships documented in the literature. The chapter also addresses the question of farmer attitudes and how these may co-vary with organic practice with important implications for biodiversity. These strands are then brought together into commentary on the way forward, including future research priorities.
