Pine Seedling Survival and Growth Related to Moisture Retention of Eight Texas Forest Soils
Loblolly (Pinus taeda L.) and shortleaf (Pinus echinata Mill.) pines reach the extent of their western distribution in east Texas. Mature specimens of these pines occur sporadically among the oaks in the "tension zone" or "pine fringe," the transition zone between the pine type and the oak-hickory type. This indicates environmental conditions that are occasionally favorable for the natural establishment of pine (1) . Seed source availability, soil characteristics, hardwood competition, and water table variability are very likely some of the interrelated factors responsible for the occurrences of scattered pine.
