SPR01 Sequential prairie restoration experiment at Konza Prairie

Abstract: 

Annual aboveground net primary productivity (ANPP) from the Sequential Prairie Restoration Experiment at the Konza Prairie Long-Term Ecological Research site in Manhattan, KS USA. The data include ANPP from the first three years of restoration in each of three restoration sequences initiated in different years. Data correspond to subplot and whole-plot analyses. The Sequential Prairie Restoration Experiment is a block design with 4 subplots (labeled A - D) within 4 main plots (numbered 1 - 4) sequentially replicated in three blocks (Sequences 1, 2 and 3), with the restoration in each block initiated in a different year (Sequence 1 initiated in 2010, Sequence 2 initiated in 2012, and Sequence 3 initiated in 2014). 'NO-COLL' indicates that variable was not measured, A period in the dataset indicates missing data.

Methods: 

Aboveground net primary productivity (ANPP) 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 (.).
