Plant biodiversity and associated environmental data for a tropical savanna following invasion by Urochloa decumbens, Cerrado region, Brazil, 2019-2021

The data comprise measurements of abundance of invasive species, illuminance, air temperature, air humidity, specific leaf area, species richness, species diversity, vegetation cover, biomass, decomposition rate and, carbon efflux that was made during filed campaigns to assess the impact of an invasive grass (Urochloa decumbens) on a tropical savanna (Cerrado) in two nature reserve areas in Brazil.

The two experimental areas were located within natural reserves in Southeast and Central Brazil; Estação Ecológica de Itirapina in the municipalities of Brotas and Itirapina in São Paulo State, and Parque Nacional de Brasília in the Distrito Federal.
Data were collected during multiple field excursions between March and September 2019.

本数据集包含为评估入侵草本植物（Urochloa decumbens）对巴西两处自然保护区内热带稀树草原（Cerrado）的影响而开展野外调查期间获取的多项测量数据，具体涵盖入侵物种丰度、光照度、空气温度、空气湿度、比叶面积（specific leaf area）、物种丰富度、物种多样性、植被盖度、生物量、分解速率及碳释放量（carbon efflux）。
两处实验区域分别坐落于巴西东南部与中部的自然保护区内：其一为圣保罗州布罗塔斯市与伊蒂拉皮纳市境内的伊蒂拉皮纳生态站（Estação Ecológica de Itirapina），其二为联邦区的巴西利亚国家公园（Parque Nacional de Brasília）。
数据采集工作于2019年3月至9月期间通过多次野外考察完成。
