Interpretive Summary: Individual plant species were collected in long-term grazed and ungrazed pastures and identified to determine plant composition and isotopic signature. The data can serve as a library of stable carbon isotope values for the Southern mixed-grass prairie species sampled. Forty one individual plant species were collected from the United States Department of Agriculture (USDA) Southern Plains Experimental Range (SPER), 2 km north of Ft. Supply, Harper County, Oklahoma, USA (99° 23’ W, 36° 27’ N; elevation 610-640 m), including seventeen warm-season (C4) and twenty-four cool-season (C3) plants. Individual plant species stable isotope ratios (d13C) have been used as a record for paleoenvironmental and paleovegetation changes as well as modern climatic and vegetation gradients across the U.S. Great Plains.

Technical Abstract: Individual plant species were collected in long-term grazed and ungrazed pastures and identified to determine plant composition and isotopic signature. The data can serve as a library of stable carbon isotope values for the Southern mixed-grass prairie species sampled. Forty one individual plant species were collected from the United States Department of Agriculture (USDA) Southern Plains Experimental Range (SPER), 2 km north of Ft. Supply, Harper County, Oklahoma, USA (99° 23’ W, 36° 27’ N; elevation 610-640 m), including seventeen warm-season (C4) and twenty-four cool-season (C3) plants. Samples were dried at 55C, and ground finely. The delta 13C isotopic compositions were determined using a Europa Scientific automated nitrogen carbon analyzer (ANCA/NT) with a Solid/Liquid Preparation Module (Dumas combustion sample preparation system) coupled to a Europa 20-20 Stable isotope analyzer continuous flow isotope ratio mass spectrometer (Sercon Ltd, formerly Europa Scientific Ltd., Crewe, England).
