This article reports the results of a inventory of the Chouteau Wildlife Management Area in eastern Oklahoma. One hundred eighty-one species of vascular were collected from 144 genera and 63 families. The families with the greatest number of species were the Asteraceae (25), Poaceae (22), and (18). Fifty-seven species were annuals, four biennials, and 120 were perennials. Thirty-nine woody plant species were present. Twenty-one species exotic to were collected representing 11.6% of the flora. Azolla caroliniana was the only species tracked by the Oklahoma Natural Heritage Inventory found. This study reports 148 species previously not documented in Wagoner County.

INTRODUCTION from 35.86o N to 35.85o N and longitudinal The objectives of this study were extent from 95.34o W to 95.37o W. The twofold: to fill a gap in floristic data for CHWMA is located within the subtropical eastern Oklahoma and provide resource humid (Cf) climate zone (Trewartha 1968). managers at the Chouteau Wildlife Summers are warm (mean July temperature Management Area (CHWMA) with a = 27.7o C) and humid, whereas winters are comprehensive species list. Prior to 1996, relatively short and mild (mean January when collecting began for this study, 198 temperature = 2.9o C). Mean annual specific and infraspecific taxa were reported precipitation is 114.5 cm, with periodic from Wagoner County (Hoagland 2004). severe droughts (Oklahoma Climatological The first collections made in Wagoner Survey 2004). County were by Robert Bebb, namesake of Physiographically, the study area is the University of Oklahoma Herbarium, in located in the Osage Plains section of the 1903 (Hoagland 2004). No additional Central Lowlands province (Hunt 1974) and collections were recorded until 1913, when within the Claremore Cuesta Plains province G. W. Stevens visited the county. The peak of Oklahoma (Curtis and Ham 1979). The collecting year in Wagoner County was 1939 surface geology is primarily Quaternary silt, (51 specimens), with work completed by R. sand, and clays deposited along the Bebb (Hoagland et al. 2004). Verdigris River (Branson and Johnson 1979). The primary soil association at STUDY AREA CHWMA is the Sage-Radley, which is The CHWMA is located on U.S. composed of deep, level to gently sloping, Army Corp of Engineers land in Wagoner poorly drained soils (Polone 1976). The County (Figure 1) and has been managed by potential natural vegetation type at the Oklahoma Department of Wildlife CHWMA is the bottomland Forest type Conservation since 1973. It encompasses (Duck and Fletcher 1943). 402 hectares, and elevation ranges from 167m to 158m. Latitudinal extent ranges

METHODS 9% at Oologah Wildlife Management Area Three collection sites were established (Hoagland and Wallick 2003), 15% at at CHWMA for intensive floristic sampling. Keystone Wildlife Management Area Sites were selected following a review of US (Hoagland and Buthod 2003), and 11% for an Geological Survey 1:24,000 topographic maps inventory of Tillman County (Hoagland et al. and field reconnaissance. The predominant 2004). However, the percentage was lower, vegetation associations at these sites were 6.6%, at Red Slough and Grassy Slough in classified according to Hoagland (2000). southeastern Oklahoma (Hoagland and Collections also were made randomly Johnson 2004). However, these studies report throughout the site. Collections were made on a higher number of exotic species in the a monthly basis from March through October Asteraceae. In addition, CHWMA is the first 1996. Vouchers for species exotic to North reported location for Alternanthera philoxeroides America were made from naturalized in Oklahoma, a noxious weed of the populations only, thus excluding cultivated southeastern United States (Hoagland and and ornamental plants.
