Abstract Marine turtles utilize sandy beaches as nesting grounds, which can be impacted by a variety of coastal modifications. In the context of limited resources, managers need to prioritize which impacts from coastal modifications to mitigate. However, data on the relative impacts of coastal modification activities are not often available. To address this, we determined the perceived relative impact of twelve coastal modification activities on marine turtle nesting grounds by eliciting information from researchers and managers who are experts on the impacts of coastal modifications on marine turtles and their nesting grounds. Experts were asked to answer a series of pair-wise comparison matrices that compared the impacts of each coastal modification activity. Beach armoring, light pollution, and other shoreline stabilization structures (such as groins and jetties) were weighted by our experts as having the greatest impact to marine turtle nesting grounds and nonpermanent coastal modifications (e.g., special events and beach cleaning) were weighted by experts as having the lowest impact to marine turtle nesting grounds. Managers can use this information to prioritize their efforts and resources to manage marine turtle nesting grounds if funds are available and policy allows.

使用专家启发确定海岸改造对海龟筑巢地的相对影响

摘要 海龟利用沙滩作为筑巢地，这可能会受到各种海岸改造的影响。在资源有限的情况下，管理人员需要优先考虑要减轻沿海改造带来的哪些影响。然而，关于海岸改造活动的相对影响的数据通常不可用。为了解决这个问题，我们通过从研究人员和管理人员那里获取信息来确定十二项沿海改造活动对海龟筑巢地的感知相对影响，他们是海岸改造对海龟及其筑巢地影响的专家。专家们被要求回答一系列成对比较矩阵，这些矩阵比较了每个沿海改造活动的影响。海滩装甲，光污染，和其他海岸线稳定结构（例如腹股沟和码头）被我们的专家加权为对海龟筑巢地的影响最大，非永久性海岸改造（例如特殊事件和海滩清洁）被专家加权为对海龟的影响最小海龟筑巢地。如果资金可用且政策允许，管理人员可以使用这些信息来确定他们的工作和资源的优先级，以管理海龟筑巢地。
