Data collected on the breeding status of the Grasshopper Sparrow by the second Iowa Birding Bird Atlas (BBAII), recorded 791 (3x3 mi2) locations over Iowa in 2008–2012. Original data sourced from https://iowabba2.org.This data has been joined to groundcover measurements from the U.S. Geological Survey (USGS). For each location, USGS data allow computation of an average percentage of area attributable to grass, trees, and covers other than crops, as well as the number of cover types within an area. These values have been calculated for both a circle that inscribes the 3x3 mi2 locations, as well as one that encompasses the locations. Each value is calculated based on satellite data from 2008 and 2019, separatetely. Original data sourced from https://www.mrlc.gov.Data includes:lat: latitude of the center of the observed locationlong: longitude of the center of the observed locationgrid: TRUE/FALSE indicator of if the observed location lies on the gridcolor: color encoded on the BBAII map, indicating breeding status at the observed locationcounty: county name housing the observed locationcomments: comments made by the observersparrow_breeding: TRUE/FALSE indicator of the Grasshopper Sparrow either suspected or observed breedingpercent_grass_inside_2008: percentage of area attributable to grass in a circle inscribing the 3x3mi2 location from 2008percent_grass_outside_2008: percentage of area attributable to grass in a circle encompassing the 3x3mi2 location from 2008percent_trees_inside_2008: percentage of area attributable to trees in a circle inscribing the 3x3mi2 location from 2008percent_trees_outside_2008: percentage of area attributable to trees in a circle encompassing the 3x3mi2 location from 2008percent_not_crop_inside_2008: percentage of area attributable ground covers other than crops in a circle inscribing the 3x3mi2 location from 2008percent_not_crop_outside_2008: percentage of area attributable ground covers other than crops in a circle encompassing the 3x3mi2 location from 2008number_covers_inside_2008: number of cover types within a circle inscribing the 3x3mi2 location from 2008number_covers_outside_2008: number of cover types within a circle encompassing the 3x3mi2 location from 2008percent_grass_inside_2019: percentage of area attributable to grass in a circle inscribing the 3x3mi2 location from 2019percent_grass_outside_2019: percentage of area attributable to grass in a circle encompassing the 3x3mi2 location from 2019percent_trees_inside_2019: percentage of area attributable to trees in a circle inscribing the 3x3mi2 location from 2019percent_trees_outside_2019: percentage of area attributable to trees in a circle encompassing the 3x3mi2 location from 2019percent_not_crop_inside_2019: percentage of area attributable ground covers other than crops in a circle inscribing the 3x3mi2 location from 2019percent_not_crop_outside_2019: percentage of area attributable ground covers other than crops in a circle encompassing the 3x3mi2 location from 2019number_covers_inside_2019: number of cover types within a circle inscribing the 3x3mi2 location from 2019number_covers_outside_2019: number of cover types within a circle encompassing the 3x3mi2 location from 2019This data is used in the following paper Biswas, E., Kaplan, A., Kaiser, M.

本数据集收录了由第二届爱荷华观鸟鸟类图集（BBAII）收集的草鹀（Grasshopper Sparrow）繁殖状态数据，于2008至2012年间覆盖爱荷华州内791个3×3平方英里的调查点位。原始数据来源于https://iowabba2.org。本数据集已与美国地质调查局（U.S. Geological Survey, USGS）的地表覆盖测量数据进行拼接。针对每个调查点位，USGS数据支持计算该区域内草地、林木及非农作物地表覆盖的平均占比，同时可统计区域内的地表覆盖类型数量。上述指标分别基于覆盖该3×3平方英里点位的内切圆形区域，以及环绕该点位的外切圆形区域进行计算，且均分别基于2008年与2019年的卫星遥感数据测算得出。地表覆盖数据的原始来源为https://www.mrlc.gov。数据包含以下字段： **lat**：观测点位中心的纬度 **long**：观测点位中心的经度 **grid**：布尔型标识，用于指示观测点位是否位于调查网格之上 **color**：BBAII地图上的颜色编码，用于表征该观测点位的草鹀繁殖状态 **county**：观测点位所在的县名 **comments**：观测者留下的备注信息 **sparrow_breeding**：布尔型标识，用于指示草鹀存在疑似或已观测到的繁殖行为 **percent_grass_inside_2008**：2008年，内切于3×3平方英里观测点位的圆形区域内草地覆盖面积占比 **percent_grass_outside_2008**：2008年，环绕3×3平方英里观测点位的圆形区域内草地覆盖面积占比 **percent_trees_inside_2008**：2008年，内切于3×3平方英里观测点位的圆形区域内林木覆盖面积占比 **percent_trees_outside_2008**：2008年，环绕3×3平方英里观测点位的圆形区域内林木覆盖面积占比 **percent_not_crop_inside_2008**：2008年，内切于3×3平方英里观测点位的圆形区域内非农作物地表覆盖面积占比 **percent_not_crop_outside_2008**：2008年，环绕3×3平方英里观测点位的圆形区域内非农作物地表覆盖面积占比 **number_covers_inside_2008**：2008年，内切于3×3平方英里观测点位的圆形区域内的地表覆盖类型数量 **number_covers_outside_2008**：2008年，环绕3×3平方英里观测点位的圆形区域内的地表覆盖类型数量 **percent_grass_inside_2019**：2019年，内切于3×3平方英里观测点位的圆形区域内草地覆盖面积占比 **percent_grass_outside_2019**：2019年，环绕3×3平方英里观测点位的圆形区域内草地覆盖面积占比 **percent_trees_inside_2019**：2019年，内切于3×3平方英里观测点位的圆形区域内林木覆盖面积占比 **percent_trees_outside_2019**：2019年，环绕3×3平方英里观测点位的圆形区域内林木覆盖面积占比 **percent_not_crop_inside_2019**：2019年，内切于3×3平方英里观测点位的圆形区域内非农作物地表覆盖面积占比 **percent_not_crop_outside_2019**：2019年，环绕3×3平方英里观测点位的圆形区域内非农作物地表覆盖面积占比 **number_covers_inside_2019**：2019年，内切于3×3平方英里观测点位的圆形区域内的地表覆盖类型数量 **number_covers_outside_2019**：2019年，环绕3×3平方英里观测点位的圆形区域内的地表覆盖类型数量本数据集被应用于下述论文：Biswas, E., Kaplan, A., Kaiser, M.
