Additional data relating to farm system, farm-level nutrient inputs, stocking rates, and participation (or otherwise) in the Irish Rural Environment Protection Scheme (REPS) were collated. Generalized linear models (GLM) showed that farm system was a predominant influence explaining observed biological diversity. Both sward plant and arthropod diversity were greater on non-dairy (drystock) farms, but total arthropod abundance was greater on dairy farm swards. Both the breeding bird abundance and species richness were significantly greater in field boundaries on dairy, compared with non-dairy farms. These insights have relevance to the debate regarding the most effective use of public expenditure on agri-environment policy, and suggest that such incentive schemes need to become more clearly customised to realise the conservation potential of different farming systems.||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||Agriculture, Ecosystems & Environment||Volume:||139||Issue:||1-2||Start page:||232||End page:||238||Copyright (published version):||2010 Elsevier B.V.||Keywords:||Bird populations; Conservation ecology; Invertebrate abundance; Dairy farm||DOI:||10.1016/j.agee.2010.08.008||Language:||en||Status of Item:||Peer reviewed|
