筑巢海滩调查是全球海龟界使用最广泛的监测工具，也是评估和监测海龟种群状况综合计划的重要组成部分。这些评估对于评估在所有生命史阶段实施的恢复和保护活动的效果是必要的。适当设计的筑巢海滩调查，结合筑巢雌性（参见 Alvarado 和 Murphy，本卷；Balazs，本卷；Owens，本卷）和筑巢成功率（参见 Miller，本卷）的研究，可以提供与每年沉积的巢数量、每年繁殖活跃的筑巢雌性数量以及巢年生产力相关的信息。本章讨论的筑巢海滩调查是指为收集非阿里巴达海滩筑巢和非筑巢现象数量信息而进行的地面和/或空中调查。考虑对大规模筑巢海滩进行人口调查的读者应该查阅巴尔韦德和盖茨的这本书。
Nesting beach surveys are the most widely implemented monitoring tool in use by the global sea turtle community and are an important component of a comprehensive program to assess and monitor the status of sea turtle populations. These assessments are necessary to evaluate the effects of recovery and conservation activities which are being implemented at all life history stages. Appropriately designed nesting beach surveys, in concert with studies of nesting females (see Alvarado and Murphy, this volume; Balazs, this volume; Owens, this volume) and nest success (see Miller, this volume), can provide information relative to the number of nests deposited annually, the number of nesting females that are reproductively active annually, and annual nest productivity. Nesting beach surveys, as discussed in this chapter, refer to ground and/or aerial surveys conducted to gather information on the number of nesting and non-nesting emergences occurring on a nonarribada beach. Readers contemplating population surveys on mass nesting beaches should consult Valverde and Gates, this volume.
