Abstract:We examine the relative merits of alternative forest biodiversity targets, which give different weights to species according to their conservation status and abundance. A site selection framework is used for choosing the habitat-protection strategy that maximizes biodiversity subject to an upper bound on funding with six alternative conservation goals. By using Finnish data on old-growth forests, we found that alternative conservation goals yield different benefit-cost tradeoffs. Goals relying on complementarity between protected stands result in great marginal costs at a high conservation level. Therefore, under these conditions it may not be economically efficient to establish a large conservation network to protect all species in a given area. In contrast, a large conservation network is more likely to be justified when the habitat-protection strategy focuses on species abundance. The trade-offs between alternative objectives are explicitly measured by incrementally varying the weights given to the species. We found that the targets for all species representation and species abundance can largely be met simultaneously. Protecting red-listed species reduces overall species coverage and species abundance particularly at low budget levels.
