The human aspects of conservation are often overlooked but will be critical for identifying strategies for biological conservation in the face of climate change. We surveyed the behavioral intentions of coastal landowners with respect to various conservation strategies aimed at facilitating ecosystem migration for tidal marshes. We found that several popular strategies, including conservation easements and increasing awareness of ecosystem services, may not interest enough landowners to allow marsh migration at the spatial scales needed to mitigate losses from sea-level rise. We identified less common conservation strategies that have more support but that are unproven in practice and may be more expensive. Our results show that failure to incorporate human dimensions into ecosystem modeling and conservation planning could lead to the use of ineffective strategies and an overly optimistic view of the potential for ecosystem migration into human dominated areas.
保护的人文层面常常被忽视，但在面对气候变化时，它对于确定生物保护策略至关重要。我们调查了沿海土地所有者对各种旨在促进潮间带湿地生态系统迁移的保护策略的行为意向。我们发现，包括保护地役权和提高对生态系统服务的认识在内的一些流行策略，可能不会引起足够多的土地所有者的兴趣，无法在缓解海平面上升带来的损失所需的空间尺度上允许湿地迁移。我们确定了一些不太常见的保护策略，这些策略得到了更多的支持，但在实践中尚未得到证实，而且可能更昂贵。我们的研究结果表明，如果不将人文因素纳入生态系统建模和保护规划中，可能会导致使用无效的策略，并对生态系统向人类主导地区迁移的潜力产生过于乐观的看法。
