Methods

The experiment was conducted in a tallgrass prairie on the KesslerFarm Field Laboratory in Oklahoma. USA (34?590N. 97?310W). Thestudy site was neither cultivated nor grazed by large herbivores forthe past 40 years prior to the start of the experiment. Species abundance was estimated at peak biomass in August from2000 to 2013. We measured species abundance using the point-quadratmethod. From 2000 to 2004. a grid frame (1 m 9 0.5 m) with 36points was placed once in the centre of each subplot. The plant speciestouched by a pin placed at each point on the grid was recordedas one hit. Beginning in 2005. community assessment was combinedwith the pin-contact method. Ten pins. 5 cm apart between any adjacenttwo pins. were held at a 60? angle in a frame placed in each subplotfour times (once in each of the four cardinal directions). and pinscould be raised within the frame to count hits up to 1 m high. Onehit was recorded for each species if they touched any part of the pins.and species having no contact with any of the pins was recorded asone hit. Yearly estimation of abundance at peak biomass in august. Unit of abundance = IndCountInt, Unit of biomass = NA
