In this study, the cost-effectiveness of government expenditure is investigated by comparing the cost of grant aid with the ecosystem restoration potential of new woodlands. An expert- based system for scoring ecosystem restoration potential is described and applied to over 200 new woodlands in a Geographic Information System. New woodlands varied considerably with respect to both cost and ecosystem restoration score, with the most cost-effective woodlands established close to existing woodlands using natural colonisation techniques. Overall ecosystem score was negatively correlated with government expenditure. Alternative approaches to improving the cost-effectiveness of grant aid are discussed.
