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.
