Ecosystems are increasingly characterised as goods and services to allow their valuation in monetary terms. This follows an orthodox economic approach to environmental values, but is also being undertaken by ecologists and conservation biologists. There then appears a lack of clarity and debate as to the model of human behaviour, specific values and decision process being adopted. Arguments for ecosystems service valuation are critically appraised and the case for a model leading to value pluralism is presented. The outcome is to identify the need for value articulating processes which involve open deliberative judgment rather than instantaneously stated preferences, concealed expert opinion and global cost-benefit analysis.
