COUNTY RECORDS AND MAJOR RANGE EXTENSIONS FOR WEST CROSS TIMBERS ANGIOSPERMS FROM HUNEWELL RANCH IN ERATH COUNTY, TEXAS.

Knowledge of floras across Texas is vital for cataloging species composition, management, and preservation of individual plant species and ecoregions. The trend for complete floristic knowledge is observed with such databases as the United States Department of Agriculture's (USDA) Plants Database (2016) and the Texas Parks and Wildlife (TPWD) Plant Information Database (2016). Floristic data for Erath County (Fig. 1), located in the southwestern portion of the West Cross Timbers (WCT), is dated and incomplete.

Hunewell Ranch (Hunewell) is a 474.3 ha ranch currently owned and maintained by Tarleton State University (TSU) in Stephenville, Texas (coordinates at the entrance gate: 32[degrees]12.901 N, 98[degrees]06.147W). Hunewell Ranch is currently dominated by post oak-blackjack oak savannah, midgrass prairie, and tallgrass bottomland areas (Parker 2001). Two riparian areas exist on Hunewell Ranch and include Richardson and Sycamore creeks, which transverse the ranch in an east-west direction. Ephemeral drainage ditches, multiple seasonal stock ponds distributed across the ranch, and gently sloping terrain typified by occasional flooding is prevalent (Parker 2001). Purves and Windthorst soils are the two primary soil series that occur at Hunewell (Parker 2001). Purves soils are generally shallow, calcareous and clayey soils overlaying limestone, whereas Windthorst soils are moderately deep sandy and sandy loam soils (Wagner et al. 1973). Livestock grazing tends to be Hunewell's largest disturbance, especially in areas closest to the Richardson Creek road crossing and ranch buildings. Juniper invasion has become problematic throughout the ranch (Vickery 1991). Occasional prescribed burning and mechanical brush removal has been used to reduce invasion (Parker 2001), but extensive brush removal has not been a prevalent management practice.

MATERIALS & METHODS

Field work was conducted at Hunewell Ranch over a twelvemonth period from September 2006 to August 2007 and again from January 2009 to December 2009. Twelve localities within the ranch were visited monthly to collect plant specimens; however other sites were opportunistically sampled. All major plant communities and habitats occurring at Hunewell Ranch were sampled. Specimens were processed at TSU Herbarium using standard herbarium procedures (Diggs et al. 1999). Each specimen from Hunewell Ranch was identified and classified as native, endemic, or introduced using Skinner's and Mahler's Illustrated Flora of North Central Texas (Diggs et al. 1999). Plants from Hunewell Ranch will be compared to those which occur on the Texas State-listed Noxious Weeds (USDA 2016), state threatened and endangered plant species list (TPWD 2016), and rare plants of Texas (Poole et al. 2007). Distributions of taxa were compared to those published in the Atlas of the Vascular Plants of Texas (Turner et al. 2003a; 2003b).

RESULTS & DISCUSSION

This investigation provides data from a ranch within a portion of the WCT that is poorly known, floristically (Cowley 2012). Three hundred sixty species representing 72 families were identified from Hunewell Ranch. Three hundred twenty-three taxa are native and 37 are introduced species. Seven of the native species are endemic to Texas and one of the endemic species, Yucca pallida, is endemic to North Central Texas. No plants occurred on the state noxious weeds list (USDA 2016); nor were any rare (Poole et al. 2007), threatened, or endangered species (TPWD 2016) for the state. Forty-five taxa are considered new records for Erath County but also occur in counties that are adjacent to Erath County (Table 1) and 43 taxa are major range extensions into the WCT.

Harsley and Nelson (2010) identified 91 native and seven introduced species from Hunewell Ranch. Ninety-eight taxa were considered new records for Erath County and thirty-five were major range extensions for the WCT. In this investigation, forty-five taxa are considered new records for, but also occur in counties adjacent to, Erath County (Table 1). Forty-three of the taxa are major range extensions into the WCT and are discussed individually by family in the following paragraphs.
