From 2010–2022, Ireland's Burren Programme paid 328 farmers across 23,000 ha of karst grassland by ecological scorecard rather than prescription; independent evaluation found average field scores rose from 6.61 to 7.43 (2010–2019), worth an estimated €32.8M.
The Burren, a limestone karst landscape in County Clare, Ireland, supports internationally rare calcareous grassland flora that depends on traditional, low-intensity cattle grazing. The Burren Programme, successor to the EU LIFE-funded BurrenLIFE project, ran from 2010 to 2022 to keep that grazing economically viable for farmers.
Rather than paying for prescribed actions, the programme scored each field from 0 to 10 on an ecological 'scorecard' — assessing vegetation quality, scrub encroachment, grazing evidence and water-quality indicators — and paid farmers according to the outcome delivered. It also co-funded 'action-based' payments for specific conservation works such as scrub clearance, water trough installation and traditional wall repair.
By 2022 the programme covered 23,000 hectares across 328 farms. A government-commissioned evaluation, together with peer-reviewed tracking of a 147-farm subset, found average field scores rose from 6.61 in 2010 to 7.43 in 2019; Ireland's National Parks and Wildlife Service estimated the monetised value of the resulting habitat and landscape improvement at €32.8 million over the decade.
The scorecard methodology was written up as a guidance handbook for the European Commission's DG Environment on designing results-based agri-environment payments, and directly informed Ireland's national ACRES scheme (2023–), alongside sister results-based projects — the Hen Harrier Project (1,600 farmers), the Pearl Mussel Project (492 farmers) and Wild Atlantic Nature (823 farmers) — that now cover thousands of farmers nationally.
Peer-reviewed literature on results-based schemes cautions that, because payments follow a self-reported and verified score rather than a randomised control design, there is a possible 'lack of additionality': some farmers may have enrolled with land that already scored well, making the measured gain harder to attribute solely to the scheme.
