Abstract

In this chapter we will use the case of beaver reintroduction in southern Scandinavia to illuminate the philosophical issues underlying the value of biodiversity. First, we rehearse some of the main types of argument relating to the practice of ecological restoration. This is followed by a description of the case study, and by a summary of what we take to be the main positions in the ongoing debate over reintroduction of beavers. We then interpret these different positions, asking in each case how ‘biodiversity’ is being understood. In this way, we try to establish the causes of the disagreement. It is important to distinguish between disagreements caused by conflicting interests and disagreements caused by conflicting values. We shall focus on a special type of disagreement where there seems to be a genuine conflict of values pertaining to biodiversity. Finally, we show how the claim that biodiversity should be protected is made by several participants in the debate and taken to have remarkably different implications: the need to protect biodiversity has been invoked both in attacks on, and defenses of, reintroduction and other forms of ecological restoration.
