Plant invasions in the Middle Awash Valley, Ethiopia

Although natural ecosystems in Ethiopia are confronted with myriad of plant invasions, research to quantify plant invasion effects is restricted to limited areas of the country or a few species only. Data uploaded here were collected to examine the number and abundance of invasive and expanding plants (a native but spreading species) and their associated effects (individual as well as cumulative effects) on native species richness and diversity in a semi-arid rangeland in the Rift Valley Region, eastern Ethiopia. Data were gathered from forty-eight 20 X 20 m plots (established using systematic random fashion) and we recorded plant richness (both herbaceous and woody plants (comprising all trees and shrubs >1 m height)) abundance-cover, and herbaceous species composition.

尽管埃塞俄比亚的自然生态系统面临着众多植物入侵的挑战，但关于量化植物入侵影响的科研工作仅限于该国有限的区域或针对少数几种植物。本数据集所上传的数据旨在研究入侵植物（指原生物种但正在扩散的物种）及其扩展的数量和丰度，以及它们对原生物种丰富度和多样性的个体及累积影响，这些研究是在埃塞俄比亚东部裂谷地区的半干旱放牧地进行的。数据收集自四十八个20 X 20米的样地（采用系统随机方式设立），我们记录了植物丰富度（包括草本和木本植物（包括所有树和灌木，高度超过1米））、丰度-覆盖度，以及草本物种组成。
