Prairie Facts


The Piney Woods topography is gently rolling to hilly forested land. It is part of a much larger region of pine-hardwood forest that extends into Louisiana, Arkansas, and Oklahoma. Elevation in Texas varies from 200 to 500 feet above sea level. Humidity and temperatures are typically high and the area is comparatively free from persistent winds. Soils are mostly pale to dark gray sands or sandy loams and are generally acidic.

The area is interspersed with native pine-hardwood vegetation, farm lands, and pasture. Deer are locally abundant throughout the Piney Woods. Ranches are varied in size; cattle are the primary livestock. Paper pulp production is an important economic pursuit within this

The southeastern part was once dominated by the Longleaf Pine Forest, while mixed pine/oak occurs west and north of the Piney Woods. Major trees species are loblolly and yellow pine, and blackjack and post oak. Hardwood forests of sweetgum, magnolia, tupelo, elm, and ash occur in the lowlands. Swamps are common and are most outstanding in the southern part of the Pine-Oak Forest.

Herbs and shrubs are plentiful in the Piney Woods, including predominant populations of Andropogon, Sporobolus, Panicum, Paspalum, Muhlenbergia, Eragrostis, Chasmanthium, Broomsedge (Andropogon virginicus), smutgrass (Sporobolus indicus), red lovegrass (Eragrostis oxylepis), and Indiangrass (Correll and Johnson).

Introductions of grasses and legumes, mostly for complicated the plant successional patterns. Some of these plants have invaded or have been over seeded in native vegetation. The most important of these are Bermuda grass (Cynodon Dactylon), Dallis grass (Paspalum dilatatum), Vasey grass (Paspalum Urvillei), carpet grass (Axonopus affinis), Medicago spp., Lespedeza spp. and others.

In the extreme southeast around Jasper, there are broad, flat savannahs intergrading with shrub bogs within the pineywoods. These savannahs are underlain by a fluctuating water table, and support a rather distinctive and interesting flora including several species of orchids, as well as sundews-Drosera spp., pipeworts - Eriocaulon spp. and numerous sedges, grasses, and bulrushes (Correll and Johnson).
