Aboveground net primary productivity (ANPP) (SRP011) was estimated by harvesting biomass from two 0.1 m2 randomly placed quadrats (except for sequence 2 in 2012 and 2013, which had 4 replicates sampled within deer exclosures nested in each subplot) in September, at peak biomass, from each of the 16 subplots within each restoration sequences. Biomass was clipped at the end of each growing season in 2010, 2011, 2012, 2013, 2014, 2015, and 2016. Biomass was dried for 1 week at 60°C, sorted into planted species, non-planted species, and surface litter (not collected in all years), and weighed. Biomass in each subplot was multiplied by 10 to convert ANPP to units of g m-2 y-1. Missing data is represented by a period (.).

Plant species composition (SRP012) is measured twice a year in May and September, with the exception of the year when a sequence was installed and composition was not measured that May. The maximum cover of species across both time points was recorded. All subplots were sampled through the 6th growing season, afterwhich only half of the subplots were sampled. The subplots sampled after the 6th growing season were randomly selected from each plot for each sequence and the same subplots were sampled over time. All plant species in a permanent 10 m2 circular plot within a subplot were recorded, and the canopy cover of each species was estimated using a modified Daubenmire scale.
