Treatment_Through_Time.xls [Note that this dataset overlaps with Survey2015.xls, but includes only one starting planting year (2008) and monitoring surveys in 2009, 2010, 2011, and 2015.] Treatment is forb only (F), grass only (G), grasses and forbs planted simultaneously (B), forbs then grasses added one year later (FG), grass then forbs added one year later (GF), and an unseeded control (C).  Year is the number of years after the initial seeding when the survey took place. Data was collected 1, 2, 3, and 8 years after initial seeding.  The rest of the columns are visual estimates of species cover. SP (Stipa pulchra), PS (Poa secunda), KM (Koeleria macrantha), HB (Hordeum brachyantherum), AM (Achillea millefolium), CC (Calandrinia ciliata), LP (Lotus purshianus), LF (Lupinus formosus). Survey2015.xls [Note: this dataset overlaps with that in Treatment_Through_Time, but includes all three planting years (2008, 2009, 2010) and only has survey data from 2015 (6-8 years after initial planting)] Treatment is forb only (F), grass only (G), grasses and forbs planted simultaneously (B), forbs then grasses added one year later (FG), grass then forbs added one year later (GF), and an unseeded control (C).  PlantingYear is the year of experiment initiation (1 = 2008, 2 = 2009, 3 = 2010, 0 = unseeded control).  The rest of the columns are visual estimates of species cover. SP (Stipa pulchra), PS (Poa secunda), KM (Koeleria macrantha), HB (Hordeum brachyantherum), AM (Achillea millefolium), CC (Calandrinia ciliata), LP (Lotus purshianus), LF (Lupinus formosus). Weed is any exotic grass or forb, and Bare is bare ground.
