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正面临着种类繁多的植物入侵问题，但当前旨在量化植物入侵影响的相关研究仅局限于该国少数区域或少数物种。本数据集收录的数据采集自埃塞俄比亚东部大裂谷（Rift Valley）地区的一处半干旱牧场，用于探究入侵植物与扩张性植物（即本土但正在扩散的物种）的数量与多度，及其对本土物种丰富度与多样性的单独及累积影响。数据通过系统随机法布设样地，共采集48个20×20米样地的相关信息，记录内容涵盖植物丰富度（包含所有株高＞1米的乔木、灌木在内的草本与木本植物）、多度盖度，以及草本植物的物种组成。
