Data for L.R. Johnson and S.N. Handel - Restoration treatments in urban park forests drive long-term changes in vegetation trajectories - Ecological Applications doi:10.1890/14-2063.1

Initial data from long-term research plots in New York City Park forest patches invaded by exotic woody plant species. Half (n = 30) of the sites were restored 15-20 years prior to first sampling in 2009-2010. The same suite of invasive plants was recorded in the other half of the sites at the time of initial restoration in the late 1980s and early 1990s (n = 30), but they were not restored in 2009-2010.本数据集源自纽约城市公园森林斑块的长期研究样地，这些斑块均已遭受外来木本植物物种入侵。其中一半样地（n=30）在2009-2010年首次采样前的15至20年间已完成生态修复。另一半样地（n=30）在1980年代末至1990年代初首次启动修复工作时，同样记录到了该类入侵植物，但这些样地并未在2009-2010年开展修复作业。
