Positive correlation between Ammospiza caudacuta (Saltmarsh Sparrow) capture and productivity supports use of a novel rapid assessment monitoring protocol

Salt marshes in the northeastern United States provide critical breeding habitat for tidal marsh specialist birds like the Saltmarsh Sparrow (Ammospiza caudacuta). The Saltmarsh Sparrow population has declined by nine percent annually, necessitating immediate conservation actions for this vulnerable species. However, estimating species vital rates across a large geographic region is logistically challenging and cost prohibitive. Therefore, we developed and tested a rapid assessment monitoring protocol focused on reproductive metrics to enhance future conservation planning.
We used three years of intensive demographic data from 12 sites to estimate daily nest survival, nest period success, fledglings produced per female, and successful broods per female. We implemented the rapid assessment protocol co-located at intensive sites in the same years to estimate the number of captured females and juveniles. We used Pearson’s correlation analyses to determine the association of intensive metri..., Our data was collected through numerous field seasons by trained surveyors in tidal mashes across the northeastern United States. At each field site an array of different survey methods were utilized inculding mark-recpature techniques for survival analyses, and nest searching and monitoring for nest survival analyses. Our survey data was imported to the SHARP Demographic Database (https://sharp-qa.azurewebsites.net/) and maintained and QAQC'd by researchers at collaborating universities (University of Maine, University of Nuw Hampshire, University of Connecticut, State UNiversity of New York SChool of Environmental Science and Forestry, and University of Delaware).

The dataset contents include mark-recapture data, nest monitoring data, and a file that includes productivity data from nest survival analyses (e.g., daily nest survival, nest period success, fledglings produced per female, and broods produced per female) and raw capture data of females and juveniles. All data was collected in tidal marshes throughout the global breeding range of the Ammospiza caudacuta (Saltmarsh Sparrow).

美国东北部的盐沼（salt marshes）为盐沼雀（Saltmarsh Sparrow，学名Ammospiza caudacuta）这类潮汐盐沼特化鸟类提供了至关重要的繁殖栖息地。盐沼雀的种群正以每年9%的速率持续下降，因此亟需针对这一脆弱物种采取即时保护行动。然而，在大范围地理区域内估算物种种群生命率（vital rates），在后勤保障层面极具挑战且成本高昂。为此，我们开发并测试了一套以繁殖指标为核心的快速评估监测方案，以优化未来的保护规划工作。

我们利用来自12个监测点的三年高密度种群统计数据，估算了每日巢存活率、巢周期成功率、每只雌鸟的离巢幼鸟数量以及每只雌鸟的成功育雏窝数。同年，我们在上述高密度监测点同步实施快速评估方案，以估算捕获的雌鸟与幼鸟个体数量。我们采用皮尔逊（Pearson）相关分析，以确定高密度监测指标与快速评估指标之间的关联……（原文此处截断）。我们的数据集源自美国东北部潮汐盐沼中，经专业培训的调查员历经多个野外调查季收集的观测数据。在每个野外监测点，我们采用了多种调查方法，包括用于存活分析的标记重捕法（mark-recapture techniques），以及用于巢存活分析的巢搜寻与监测手段。我们将所有调查数据导入至SHARP种群统计数据库（SHARP Demographic Database，https://sharp-qa.azurewebsites.net/），该数据库由合作高校的研究人员进行维护，并开展质量保证与质量控制（QAQC）工作，合作高校包括缅因大学、新罕布什尔大学、康涅狄格大学、纽约州立大学环境科学与林业学院以及特拉华大学。
