In a scenario of global change, with increasing temperatures and extreme climatic events, healthy forests are at risk. Forests have to fight several types of biotic and abiotic stress. Prospective scenarios warn of the negative effects that forests will suffer in upcoming decades (drought, fires, pests, diseases, etc.), consequently making it necessary to implement actions that can not only prevent the attack of biotic agents such as fungi and insects but also improve the resilience of forest systems. Such warning scenarios transcend the scientific sphere, and as such, Spanish society has previously expressed considerable concern about the appearance of pests and diseases caused by biotic agents. This article therefore analyzes the social preferences for pest and disease mitigation programs in Spanish forests. A discrete choice experiment was consequently carried out, and the willingness to pay was estimated for various characteristics of mitigation programs. The results show that society positively values these programs, mainly when they are applied in relatively nearby forests, when they are targeted at mixed forests, and when there is low uncertainty about their effectiveness. Conversely, the self-management of subsidies by forest owners is rejected, with a preference for funds being managed by regional public authorities.

在全球变化的情况下，随着气温升高和极端气候事件，健康的森林处于危险之中。森林必须对抗几种类型的生物和非生物胁迫。前瞻性情景警告森林将在未来几十年内遭受负面影响（干旱、火灾、害虫、疾病等），因此有必要采取行动，不仅可以防止真菌和昆虫等生物制剂的攻击，而且还可以提高森林系统的复原力。这种警告情景超越了科学领域，因此，西班牙社会此前对由生物制剂引起的病虫害的出现表示了相当大的关注。因此，本文分析了西班牙森林中病虫害减缓计划的社会偏好。因此进行了离散选择实验，并根据缓解计划的各种特征估计了支付意愿。结果表明，社会对这些计划给予了积极评价，主要是当它们应用于相对较近的森林时，当它们针对混交林时，以及它们的有效性不确定性较低时。相反，森林所有者对补贴的自我管理被拒绝，而倾向于由地区公共当局管理资金。当它们的有效性不确定性较低时。相反，森林所有者对补贴的自我管理被拒绝，而倾向于由地区公共当局管理资金。当它们的有效性不确定性较低时。相反，森林所有者对补贴的自我管理被拒绝，而倾向于由地区公共当局管理资金。
