Private land often encompasses biodiversity features of high conservation value, but its protection is not straightforward. Commonly, landowners’ perspectives are rightfully allowed to influence conservation actions. This unlikely comes without consequences on biodiversity or other aspects such as economic considerations, but these consequences are rarely quantitatively considered in decision-making. In the context of boreal mire protection in Finland, we report how acknowledging landowners’ resistance to protection changes the combination of mires selected to conservation compared to ignoring landowners’ opinions. Using spatial prioritization, we quantify trade-offs arising between the amount of landowners’ resistance, protected biodiversity, and financial costs in different conservation scenarios. Results show that the trade-offs cannot be fully avoided. Nevertheless, we show that the systematic examination of the trade-offs opens up options to alleviate them. This can promote the evaluation of different conservation policy outcomes, enabling better-informed conservation decisions and more effective and socially sustainable allocation of conservation resources.

私人土地通常包含具有高保护价值的生物多样性特征，但其保护并不简单。通常，土地所有者的观点被允许影响保护行动。这不太可能对生物多样性或经济考虑等其他方面产生影响，但在决策中很少定量考虑这些后果。在芬兰北方沼泽保护的背景下，我们报告了与忽略土地所有者的意见相比，承认土地所有者对保护的抵制如何改变选择进行保护的沼泽组合。使用空间优先排序，我们量化了不同保护情景中土地所有者的抵抗、受保护的生物多样性和财务成本之间的权衡。结果表明，不能完全避免权衡。尽管如此，我们表明对权衡的系统检查开辟了减轻它们的选择。这可以促进对不同保护政策成果的评估，使保护决策更明智，更有效和社会可持续地分配保护资源。
