Data from: We built it; did they come? Pollinator diversity and community structure in a post-mining prairie restoration project

Pollinator and flowering plant surveys were conducted in three mineland reclamation sites in southeast Ohio during 2019. Floral abundance, floral richness, floral evenness, pollinator richness, and pollinator Shannon’s diversity were calculated from these surveys and counts of individual taxa are also included in the dataset. The sampling month (June, July, August, or September) and seeding treatment (Traditional, Native Light, or Native heavy) were also recorded. Sites were privately owned abandoned mine lands and had variable soil conditions, area, seeding dates, and other minor factors, all detailed in Swab et al (2017). Three plots of 0.4 ha were established at each site. Two plots were revegetated with an experimental native prairie seed mix comprised of both non-native species typically used in reclamation, as well as native species including Panicum virgatum, Sorghastrum nutans, Chamaecrista fasciculata, Coreopsis tinctoria, Rudbeckia triloba, Helianthus maximiliani, and Asclepias syriaca, as well as nonnatives Lotus corniculatus, Lolium perenne, and Dactylis glomerata as insurance, at 16.81 kg ha-1 (Native Light) and 33.63 kg ha-1 (Native Heavy) rates. The other plot was revegetated with a non-native mix frequently used in the reclamation of mine lands in Ohio (Traditional), with a seeding rate of 33.63 kg ha-1. Each site was sampled four times from June-September 2019 on warm (21-32°C) days with no rainfall and ≤ 4.0 m/s winds. One site was sampled per day and subsequent sampling events at each site were approximately 4 weeks apart. Within each plot, 25-m transects were established from a central point, choosing direction with a random number generator. One transect per plot was surveyed per round (early morning, late-morning, and afternoon) a total of three per plot. The counts of pollinators and floral units, respectively, were summed by taxa across quadrats and six-minute walks for each plot by sampling session combination (n = 36). To account for blocking by site, plots nested within sites, and repeated measures on plots, random intercepts of site, plot, and interaction of site and plot were included, despite zero variances, in all univariate models.

Resource description: Diversity indices and counts of pollinator and flowering plants in reclaimed minelands in 2019. Seeding treatments were typical seed mix with a seeding density of 33.63 kg ha-1 (traditional), the typical plant species plus natives (Panicum virgatum, Sorghastrum nutans, Chamaecrista fasciculata, Coreopsis tinctoria, Rudbeckia triloba, Helianthus maximiliani, and Asclepias syriaca, as well as nonnatives Lotus corniculatus, Lolium perenne, and Dactylis glomerata) at 16.81 kg ha-1 (Native Light), and typical plant species plus natives at a higher density at 33.63 kg ha-1 (Native Heavy).

2019年，在俄亥俄州东南部的三个矿区复垦地进行了授粉昆虫及开花植物的调查研究。通过对这些调查数据的分析，计算了花量、花丰富度、花均匀度、授粉昆虫丰富度和授粉昆虫香农多样性指数，并记录了个体类群的计数。同时，还记录了采样月份（六月、七月、八月或九月）和播种处理（传统、本土轻混或本土重混）。这些地点为私有废弃矿地，土壤条件、面积、播种日期及其他次要因素各异，具体细节可见Swab等（2017年）的研究。在每个地点建立了三个0.4公顷的样地。其中两个样地被复垦为包含非本地物种（如 Panicum virgatum、Sorghastrum nutans、Chamaecrista fasciculata、Coreopsis tinctoria、Rudbeckia triloba、Helianthus maximiliani 和 Asclepias syriaca）以及本地物种的实验性本土草地种子混合物，非本地物种包括 Lotus corniculatus、Lolium perenne 和 Dactylis glomerata 以提供保险，播种密度分别为16.81 kg ha-1（本土轻混）和33.63 kg ha-1（本土重混）。第三个样地则复垦为在俄亥俄州矿山复垦中常用的非本地植物混合物（传统），播种密度为33.63 kg ha-1。从2019年6月至9月，在温暖（21-32°C）且无降雨且风速≤4.0 m/s的日子里，对每个地点进行四次采样，每天采样一个地点，后续采样事件在每个地点之间大约相隔4周。在每个样地内，从中心点向外建立了25米的样带，方向由随机数生成器确定。每个样地每轮（清晨、上午晚些时候和下午）进行一次样带调查，总共每个样地三次。分别按类群汇总了授粉昆虫和花单位的计数，并针对每个样地以及采样会话组合（n = 36）进行了六分钟行走调查。在所有单变量模型中，尽管方差为零，但仍包括了由地点、样地和地点与样地交互作用引起的随机截距，以考虑地点内的嵌套样地以及样地上的重复测量。
