N2 - Survival and growth of seven species/treatment combinations were tested on Tonkawa fine sand (thermic, coated Typic Quartzipsamment) in Nacogdoches County, Texas. In January 1983, seedlings were hand-planted on an intensively prepared clearcut site on the Tonkawa soil series in northern Nacogdoches County. Tonkawa sands serve as recharge zones for the Carrizo aquifer, a major source of clean groundwater for much of East Texas. Intensive management practices on this sensitive site created severe site conditions, providing incentive for the study. Species/ treatment combinations were: untreated loblolly (Pinus taeda L.) pine (LOB/CON); Terra-SorbTM -treated loblolly (LOB/Tm);olin clay slurry-treated loblolly (LOB/CLA); untreated slash (P. elliottii Engelm.) pine (SLA/CON); Terra-Sorb-treated slash (%A/ TBR); kaolin clay slurry-treated slash (SLA/ CLA); and containerized longleaf pine (P. alustris Mill.) (LL/CONT). Treatments were applied as a bareroot+up prior to planting, to increase soil moisture retention near the roots, and subsequently increase survival. Containerized longleaf yielded the highest survival (greater than 50 percent) throughout the study, followed by LOB/TER (38 percent), while all other treatments were unacceptable (below 30 percent by the end of the sixth year). Management recommendations include reforest the site in longleaf pine or allow the natural scrub vegetation to inhabit the site, while managing for nontimber resources, such as groundwater, wildlife, and recreation.
