Ranch Brook Macroinvertebrate Community Assessments

Macroinvertebrate Community Assessments are based primarily on eight metrics of the Macroinvertebrate community. These include metrics of abundance, species richness, and indexes of Sensitive to tolerant species ratios. Data come from Ranch Brook at a location about 50 m below the first bridge crossing in Mansfield state park (44.50361, -72.78194) and were extracted from https://anrweb.vt.gov/DEC/IWIS/.大型无脊椎动物群落评估（Macroinvertebrate Community Assessments）主要基于大型无脊椎动物群落的八项指标展开，具体涵盖丰度指标、物种丰富度指标以及敏感种与耐受种比值指数。数据采集自曼斯菲尔德州立公园内首个跨溪桥梁下游约50米处的牧场溪（Ranch Brook），采样点位坐标为(44.50361, -72.78194)，所有数据均提取自https://anrweb.vt.gov/DEC/IWIS/。
