Zumwalt Prairie Fire Grazing Ordination Data
Description
This dataset was used to analyze the effects of prescribed fire, livestock grazing and ventenata cover on vegetation and soil surface characteristics in an experiment with four treatments: prescribed fire (BURN), livestock grazing (GRAZ), combined fire and grazing (BOTH), and no fire or grazing (CNTL). This experiment took place on a bunchgrass grassland in northeast Oregon, USA and spanned 14 years (2008 - 2021), with data collected in 5 of those years. Treatments were replicated four times. Burn treatments were applied on the landscape within blocks and grazing treatments were nested within the burned and unburned sections of each block. Prescribed fire was applied in two years (2006, 2016) and livestock grazing occurred annually. The data consists of species cover data, summarized by treatment and year for the purpose of ordination analysis.

Steps to reproduce
Raw data were collected using line-point intercept methods (see Bonham, C.D., 2013 Measurements for Terrestrial Vegetation, 2nd edition. UK: John Wiley & Sons.). Plants were identified to species level or, in some cases, only to genus level. The percent cover of each species (by plot) was calculated as the number of points with that species divided by the total number of points per plot.
