PBG11 Stream water chemistry for the Shane Creek drainage basin in the Patch-Burn Grazing experiment at Konza Prairie

PBG datasets are associated with a long-term, large-scale study that is addressing the effects of fire-grazing interactions in the context of a Patch-Burn Grazing management system designed to promote grassland heterogeneity. Effects of patch-burn grazing management on plant and animal diversity and the nature and variety of wildlife habitat are being assessed in two replicate management units, each consisting of three pastures (watersheds) designated C03A/C03B/C03C and C3SA/C3SB/C3SC. In each patch-burn grazing unit, one watershed is burned and two that are left unburned in a given year. The burning treatments are rotated annually so that each pasture is burned every third year. Each patch-burn grazing unit is paired with an annually-burned pasture for comparison with traditional grazing systems (C01A and C1SB). All grazing units are stocked with cow/calf pairs from approximately 1 May until 1 Oct at a stocking density equal to 3.2 ha per cow/calf. To examine the impact of patch burning and grazing in all 8 units, we monitor changes in plant species composition, residual biomass, grassland bird populations, insect populations, small mammal populations, soil nutrients, and stream water quality1 (1C3SA/C3SB/C3SC unit only). The KSU Department of Animal Science monitors cattle performance, including weight gain and body condition to assess the economic feasibility of using patch-burn management on a widespread basis. This data set focuses on measuring Nitrate, ammonium, total N, soluble reactive P, total P, and dissolved organic C in four streams draining watersheds with 1 (N01B), 2 (N02B), 4 (N04D), and 20 (N20B) year target burn frequencies.PBG数据集关联于一项长期大规模研究，该研究旨在探究以提升草地异质性为目标的斑块焚烧放牧（Patch-Burn Grazing, PBG）管理体系下，火-放牧交互作用所产生的效应。本研究在两个重复管理单元中评估斑块焚烧放牧管理对动植物多样性以及野生动物栖息地属性与多样性的影响，每个管理单元包含3个牧场（集水区），分别编号为C03A/C03B/C03C与C3SA/C3SB/C3SC。在每个斑块焚烧放牧单元内，每年会对1个集水区进行焚烧，剩余2个集水区不进行焚烧处理；焚烧处理每年轮换一次，确保每个牧场每3年被焚烧一次。每个斑块焚烧放牧单元均配有一个年度焚烧牧场，用于与传统放牧体系进行对照，该对照牧场编号为C01A与C1SB。所有放牧单元的载畜密度均设置为每3.2公顷饲养1头母牛-犊牛组合，放牧周期为每年5月1日至10月1日。为探究斑块焚烧与放牧在全部8个单元中的影响，本研究监测以下指标的变化：植物物种组成、残留生物量、草地鸟类种群、昆虫种群、小型哺乳类种群、土壤养分，以及溪流水质¹（注：仅C3SA/C3SB/C3SC单元开展该监测）。堪萨斯州立大学（Kansas State University, KSU）动物科学系监测牛只生长性能，包括增重与体况评分，以评估斑块焚烧放牧管理大规模应用的经济可行性。本数据集聚焦于对4条汇水溪流的养分指标进行测定，这些溪流所在集水区的目标焚烧周期分别为1年（N01B）、2年（N02B）、4年（N04D）与20年（N20B），测定指标包括硝酸盐、铵态氮、总氮、可溶性活性磷、总磷以及溶解性有机碳。
