Plant species cover and biomass for Sevilleta dominant species removal experiment.

The purpose of this research project was to connect the removal of dominant grass species in grasslands at the Sevilleta National Wildlife Refuge to changes in plant community composition and subsequent changes in aboveground biomass. We used species cover data for 23 years of a dominant species removal experiment (https://doi.org/10.6073/pasta/fd3c777524231ae245bf1916715c9140) and converted percent cover values to aboveground standing biomass using methods from Rudgers et al. 2019 (https://doi.org/10.1111/1365-2435.13463). For this project, only two sites from the original study were used blue grama (site 1) and black grama (site 3) as they are referred to in the original study.

本研究旨在厘清塞维莱塔国家野生动物保护区（Sevilleta National Wildlife Refuge）草原优势草本物种移除操作，与植物群落组成变化及后续地上生物量变化之间的关联。本研究使用了一项持续23年的优势物种移除实验的物种盖度数据（https://doi.org/10.6073/pasta/fd3c777524231ae245bf1916715c9140），并参照Rudgers等人2019年的研究方法，将百分比盖度值换算为地上现存生物量（https://doi.org/10.1111/1365-2435.13463）。本项目仅采用原始研究中的两个样地，即原始研究中所称的格兰马草（blue grama，样地1）与黑格兰马草（black grama，样地3）。
