Abstract

There is a global call for more efficient voluntary conservation practices. Voluntary conservation requires landowner participation, which may limit conservation efficiency. Here, we evaluated the ecological costs and benefits of a voluntary conservation policy relative to obligatory conservation, two hypothetical scenarios of randomly distributed conservation area networks, and two hypothetical ecologically optimized conservation area networks. The study was based on spatial conservation prioritization maps reflecting the conservation priority of forest in Central Finland. Our results suggest that voluntary conservation area networks can be relatively cost-efficient with higher nature values and better connectivity compared to a randomly selected conservation area network. Voluntary conservation area networks scored slightly higher nature values than the obligatory conservation area network but suffered from lower connectivity and smaller area size. Quality differences between the voluntary conservation area networks were minor. Our analysis showed that neither of the voluntary conservation area networks achieved its full conservation potential when compared to an ecologically optimized conservation area network. Thus, our results indicate that the societal pursuit of landowner's conservation acceptance, and hence rejection of the systematic conservation planning, has come with a cost of reduced nature values and connectivity in the current conservation area network.

北方森林保护中自愿保护政策的生态效益评价
全球都在呼吁采取更有效的自愿保护措施。自愿保护需要土地所有者的参与,这可能会限制保护的效率。在此,我们评估了自愿保护政策相对于强制性保护的生态成本和效益,以及两种假设的随机分布保护区网络和两种假设的生态优化保护区网络。该研究基于反映芬兰中部森林保护优先级的空间保护优先级图。我们的研究结果表明,与随机选择的保护区网络相比,自愿保护区网络具有较高的自然价值和更好的连通性,具有相对的成本效益。自愿性保护区网络的自然价值略高于强制性保护区网络,但连通性较低,面积较小。自愿保护区网络之间的质量差异很小。我们的分析表明,与生态优化的保护区网络相比,两种自愿保护区网络都没有充分发挥其保护潜力。因此,我们的研究结果表明,社会追求土地所有者的保护接受度,从而拒绝系统的保护规划,以当前保护区网络的自然价值和连通性降低为代价。
