Non-native relative cover including difference (Time period 2—Time period 1) and 95% confidence intervals for all plots combined (all) and each vegetation group defined from cluster analysis of species composition for time period 1(2008/2009).

Non-native relative cover including difference (Time period 2—Time period 1) and 95% confidence intervals for all plots combined (all) and each vegetation group defined from cluster analysis of species composition for time period 1(2008/2009).本数据集涵盖所有合并样地（全样地组），以及基于2008/2009年第1时期物种组成聚类分析所划定的各植被群的非本土物种相对盖度，相关数据包含第2时期与第1时期的盖度差值及对应的95%置信区间。
