Piney Woods
The Piney Woods is a temperate coniferous forest terrestrial ecoregion in the Southern States|Southern] United States covering of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. These coniferous forests are dominated by several species of pine as well as hardwoods including hickory and oak. History of [Texas forests|Historically] the most dense part of this forest region was the Big Thicket though the lumber industry dramatically reduced the forest concentration in this area and throughout the Piney Woods during the 19th and 20th centuries. The World Wide Fund for Nature considers the Piney Woods to be one of the critically endangered ecoregions of the United States. The United States Environmental Protection Agency defines most of this ecoregion as the South Central Plains.
Setting
The Piney Woods cover a area of eastern Texas, northwestern Louisiana, southwestern Arkansas and the southeastern corner of Oklahoma. They are bounded on the east by the Mississippi lowland forests, on the south by the Gulf coastal grasslands">Gulf Coastal Plain">Gulf coastal grasslands, on the west by the East Central Texas forests and the Texas blackland prairies, on the northwest by the Central forest-grasslands transition, and on the north by the Ozark Mountain forests. This area receives of precipitation annually.Flora

Longleaf, shortleaf, and loblolly pines, along with bluejack and post oaks, dominate sandhills. A well-developed understory grows beneath the sparse canopy, and includes yaupon holly and flowering dogwood. Pine savannas consist of scattered longleaf and loblolly pines alongside black tupelos, sweetgums, and in acid soils along creeks sweetbay magnolias. Other common trees in this ecoregion include eastern redbud, river birch, red maple, southern sugar maple, and American elm. American wisteria, a vine, may cover groves of trees.
Two varieties of wetlands are common in the Piney Woods: bayous are generally found near rivers and sloughs are generally found near creeks. In bayous bald cypress, Spanish moss, and water lilies are common plants. Sloughs are shallow pools of standing water that most trees are not capable of growing in. Other species, such as the purple bladderwort, a small carnivorous plant, have found niches in sloughs. A baygall is another type of wetland found the Piney Woods and other forest of the Gulf Coast states in the USA.
Hardy species of prickly pear cactus and yucca can be found in the forests where deep sands occur.
The indigenous Texas trailing phlox, an endangered species, grows in the sandy soils of longleaf pine forests.
Fauna
Mammals: Common species in the Piney Woods include White-tailed deer, Virginia opossum, northern raccoon, striped skunk, eastern mole, least shrew, eastern gray squirrel, eastern fox squirrel, and eastern cottontail. Somewhat less common are the northern river otter, bobcat, gray fox, southern short-tailed shrew, North American beaver, and swamp rabbit. Some carnivores such as the eastern spotted skunk, ringtail, long-tailed weasel, American mink, and red fox, are uncommon, rarely seen, and in decline. Over a dozen species of bats occur in the region, some migratory like the Brazilian free-tailed bat and silvered-haired bat, others are year-round residents like the Seminole bat, evening bat, Rafinesque's big-eared bat, a threatened species in Texas. Rodents found in the Piney Woods include the southern flying squirrel, common muskrat, Baird's pocket gopher, woodland vole, and about 10 additional native rats and mice.Several of the larger carnivores that once occurred in the Piney Woods are entirely extirpated, including the hog-nosed skunk, red wolf, jaguar, and ocelot. The mountain lion and black bear have also been extirpated from most areas; however, very rare sightings or remains are occasionally documented, likely representing wandering individuals rather than breeding populations. Stable populations of black bears occur in adjacent areas north and east of the Piney Woods and they appear to be slowly increasing in numbers and dispersing. As of 2020, however, the black bear is largely extirpated from most quarters, and rare in peripheral areas. With the clearing of forest and decline of the native predators, the nine-banded armadillo, coyotes, and black-tailed jackrabbit have expanded their ranges eastward into the region. Other species have been introduced into the region such as the nutria or coypu, house mouse, roof rat, and Norway rat. Feral house cats and feral pigs pose threats to native fauna and are serious conservation concerns.
Birds: With some species migrating through in the spring and fall, others nesting in the spring and summer months, and still others wintering in the region, well over 300 species of birds occur in the Piney Woods. A few of the many year round residents include the wood duck, black vulture, red-shouldered hawk, American kestrel, wild turkey, northern bobwhite, American woodcock, greater roadrunner, red-cockaded woodpecker, loggerhead shrike, northern mockingbird, brown thrasher, Carolina chickadee, brown-headed nuthatch, pine warbler, Bachman's sparrow, and fish crow. Many additional species migrate from regions south and nest in the Piney Woods in the spring and summer, such as the anhinga, yellow-crowned night-heron, little blue heron, snowy egret, purple gallinule, Chuck-will's-widow, scissor-tailed flycatcher, prairie warbler, Swainson's warbler, and painted bunting. Conversely, a different assemblage of birds migrate from the north to spend the winters months in the region, including the Canada goose, ring-necked duck, hooded merganser, blue-headed vireo, Henslow's sparrow, Le Conte's Sparrow, and Smith's longspur. A few species that once occurred in the region are now extinct like the passenger pigeon, Carolina parakeet, ivory-billed woodpecker, and Bachman's warbler.
Reptiles: The American alligator ranges throughout all but the northwestern most area of the region, however they are not particularly common in the forested habitat compared to their abundance in the open marshlands and prairies to the south. The Sabine map turtle is endemic: and among the many other turtles found in the region are the alligator snapping turtle, chicken turtle, false map turtle, river cooter, three-toed box turtle, eastern mud turtle, razor-backed musk turtle, and spiny softshell turtle. Lizards occurring in the Piney Woods include the green anole, six-lined racerunner, prairie lizard, slender glass lizard, and a number of skinks including the five-lined skink, broad-headed skink, southern coal skink, and little brown skink. Snake diversity is relatively high in the Piney Woods for a temperate area of its size, with well over 30 species ranging into the region. The Louisiana pinesnake is endemic and Slowinski's cornsnake is nearly endemic. Five venomous snakes occur in the region, the Texas coralsnake, eastern copperhead, northern cottonmouth, timber rattlesnake, and pygmy rattlesnake. Some of the non-venomous snakes include the rough greensnake, Dekay's brownsnake, eastern hog-nosed snake, western ribbonsnake, glossy swampsnake, southern watersnake, diamond-back watersnake, red-bellied mudsnake, North American racer, coachwhip, scarletsnake, prairie kingsnake, speckled kingsnake, western ratsnake. and at least a dozen others.
Amphibians: Over a dozen species of salamanders occur in the Piney Woods. The Louisiana slimy salamander of northern Louisiana and adjacent areas of southern Arkansas is endemic to the region. The three-toed amphiuma, commonly growing 18 to 30 inches, and other species such as the Gulf Coast waterdog, Red River mudpuppy, and western lesser siren are entirely aquatic. Other salamanders include the spotted salamander, marbled salamander, mole salamander, small-mouthed salamander, spotted dusky salamander, western dwarf salamander, and the eastern newt. Anurans found in the Piney Woods include Blanchard's cricket frog, Cope's gray treefrog, green treefrog, cajun chorus frog, spring peeper, eastern narrow-mouthed toad, Hurter's spadefoot toad, American bullfrog, bronze frog, pickerel frog, and southern leopard frog. The American toad occurs in northern areas and the Gulf Coast toad occurs in the south. The Fowler's toad ranges throughout Arkansas and Louisiana, but populations in east Texas intergraded with Woodhouse's toad, however some regard the east Texas populations as a distinct species, the east Texas toad.
Fish: The Piney Woods are rich in fish diversity. Fish occurring in the region include the chestnut lamprey, southern brook lamprey, paddlefish, alligator gar, spotted gar, bowfin, and redfin pickerel. Some sport fish native to the Piney Woods include largemouth bass, spotted bass, white bass, yellow bass, black crappie, white crappie, blue catfish, channel catfish, yellow bullhead, black bullhead, redear sunfish, and longear sunfish. A multitude of smaller fish inhabit the waters of the Piney Woods. Endemics include the bluehead shiner and Creole darter. The western mosquitofish, a species that has been widely introduced around the world and considered a pest in many areas, is a native in the Piney Woods. Just a few of the other small fish in the region include blacktail shiner, pallid shiner, blackspot shiner, peppered shiner, Sabine shiner, weed shiner, blacktail redhorse, freckled madtom, brown madtom, Blair's starhead topminnow, golden topminnow, blachspotted topminnow, bantma sunfish, scaly sand darter, redspot darter, mud darter, harlequin darter, and goldstripe darter.

Level IV ecoregions
Within the U.S. Environmental Protection Agency's ecoregions scheme, the Piney Woods are known as the South Central Plains, a Level III ecoregion. Within the South Central Plains, eight Level IV ecoregions are identified: Tertiary Uplands, Floodplains and Low Terraces, Pleistocene Fluvial Terraces, Cretaceous Dissected Uplands, Southern Tertiary Uplands, Flatwoods, Red River Bottomlands, and Blackland Prairie.Tertiary Uplands (35a)
The rolling Tertiary Uplands, gently to moderately sloping, cover a large area in eastern Texas, southern Arkansas, and northern Louisiana. The rolling Tertiary Uplands are dominated by commercial pine plantations that have replaced the native oak–hickory–pine forest.Ecoregion 35a is underlain by poorly-consolidated Tertiary sand, silt, and gravel; it lacks the Cretaceous, often calcareous rocks of the Cretaceous Dissected Uplands and the extensive Quaternary alluvium of Ecoregions 35b, 35g, and 73. In eastern Texas and Louisiana, Tertiary deposits are mostly Eocene clays, silts, and sands, with some Paleocene sediments to the west. Soils are loamy, well-drained, thermic Ultisols or moderately drained Alfisols, typically with sandy and loamy surface textures.
In many areas of Ecoregion 35a, commercial pine plantations have replaced the native shortleaf pine–hardwood forest. Prominent native trees include shortleaf pine, loblolly pine, southern red oak, post oak, black oak, white oak, hickories, and sweetgum. American beautyberry, sumac, greenbriar, and hawthorn are common understory species. The sandier areas often have more bluejack oak, post oak, and stunted pines. Scattered, stunted, sandhill woodlands also occur. Grasses in the area include mid and tall grasses such as yellow Indian grass, pinehill bluestem, narrowleaf woodoats, and panicums.
The landscape is dissected by numerous small streams. Waters tend to be stained by organics, thus lowering water clarity and increasing total organic carbon and biochemical oxygen demand levels. Most streams have a sandy substrate and a forest canopy. Many do not flow during the summer or early fall. However, in sandhills, spring-fed, perennial streams occur; here, total dissolved solids, total suspended solids, alkalinity, and hardness values are lower than elsewhere in the South Central Plains. Water quality in forested basins is better than in pastureland. Oil production has lowered stream quality in the south.
Timber production is the dominant land use, along with livestock grazing, poultry production, and oil and gas activities. Major settlements in the region include much of Little Rock; El Dorado, Arkansas; Texarkana; Ruston, Louisiana; and Longview, Tyler, and Nacogdoches in Texas. Protected areas include Caddo Lake National Wildlife Refuge, Poison Springs State Forest, much of Sabine National Forest, and Sabine Wildlife Management Area.
Floodplains and Low Terraces (35b)
The Floodplains and Low Terraces of Ecoregion 35 comprise the western margin of the southern bottomland hardwood communities that extend along the Gulf and Atlantic coastal plains from Texas to Virginia. Region 35b is nearly level, veneered by Holocene alluvium, and contains natural levees, swales, oxbow lakes, and meander scars. Longitudinal channel gradients are low and are less than in the Ouachita Mountains. Soils include Alfisols, Inceptisols, Vertisols, and Entisols and are generally somewhat poorly drained to very poorly drained, clayey and loamy.Large parts of Ecoregion 35b are frequently flooded. Forested wetlands are characteristic, but pastureland also occurs. Cropland is far less common than in the Red River Bottomlands. Active, meandering alluvial river channels are dynamic systems, with erosion and deposition reworking the topography of levees, ridges, and swales. Overbank flooding, subsurface groundwater, and local precipitation recharge water levels in backswamps, pools, sloughs, oxbows, and depressions of this floodplain region.
Potential natural vegetation is southern floodplain forest as in the Mississippi Alluvial Plain ; it is unlike the oak–hickory–pine forest of the higher, better drained, and lithologically distinct Tertiary Uplands and Cretaceous Dissected Uplands. Water oak, willow oak, sweetgum, blackgum, American elm, red maple, Southern red oak, swamp chestnut oak, and loblolly pine are typical. Understory flora include holly, grape genus, poison ivy, crossvine, greenbriar, and a variety of ferns and mosses. Bald cypress and water tupelo occur in semi-permanently flooded areas. Spanish moss hangs in these trees, and floating aquatic plants often occur. On wet flats, backswamps, and swamp margins that are seasonally flooded, overcup oak, water hickory, water elm, sweetgum, green ash, and red maple occur. River banks may contain black willow, sycamore, and eastern cottonwood. Wetness and flooding present severe limitations for agriculture. A few of the higher terraces may have some pasture, but most of the region has deciduous forest land cover. Silviculture activities range from selective tree removal to clearcutting to, in some areas, replacement with pine monoculture. Reservoirs have inundated large areas of this habitat and have altered downstream hydrology. The bottomland forests provide important wildlife habitat with a high diversity of species.
Settlements of the Floodplains and Low Terraces include parts of Beaumont and Lake Charles; typically these narrow and wet regions are less developed. Protected areas include Pond Creek National Wildlife Refuge, Little River National Wildlife Refuge, Felsenthal National Wildlife Refuge, Upper Ouachita National Wildlife Refuge, Sabine Island Wildlife Management Area, and Trinity River National Wildlife Refuge.
Pleistocene Fluvial Terraces (35c)
The Pleistocene Fluvial Terraces are nearly level, poorly-drained, periodically wet, underlain by Pleistocene unconsolidated terrace deposits, and often covered by pine–hardwood flatwoods. The broad flats and gently sloping stream terraces are lower and less dissected than the Tertiary Uplands, but higher than the floodplains of 35b and 35g. Soils are typically well to poorly drained Alfisols and Ultisols with loamy and sandy surfaces. Loblolly pine and oaks are common and are adapted to the prevailing hydroxeric regime; pastureland and hayland are less extensive.A vertical sequence of terraces occurs. The lowest terrace is nearly flat, clayey, and has extensive hardwood wetlands. Higher terraces become progressively older and more dissected; they are dominated by pine flatwoods, pine savanna, prairie, or a mixed forest of pine and oak; flatwood wetlands are less extensive than on the lowest terrace. The mid-level terrace is veneered with windblown silt deposits. Streams tend to be mildly acidic and stained by organic matter. They have more suspended solids, greater turbidity, and higher hardness values than the Tertiary Uplands.
The southernmost piece of 35c, around Marksville, Louisiana, is a Pleistocene terrace with some similarities in soils and historical natural vegetation to that of the Lafayette Loess Plains. The prairie has been converted to agriculture. Terraces are less extensive in Texas and Oklahoma, occurring mostly along the Red River, with some smaller terraces along the Sulphur River. In Texas, current land cover is mostly pine–hardwood forest, with post oak, Shumard oak, and eastern redcedar woods to the west. In Arkansas, loblolly pine is more common on the terraces than shortleaf pine, perhaps influenced by the seasonal wet-dry regime.
Settlements include White Hall, Arkansas; much of Pine Bluff, Arkansas; Sparkman, Arkansas; East Camden, Arkansas; Bastrop, Louisiana; Hermitage, Arkansas; Minden, Louisiana, and Ashdown, Arkansas. Protected areas include Cane Creek State Park, Seven Devils Wildlife Management Area, Crossett Experimental Forest WMA, and Lafayette WMA.
Cretaceous Dissected Uplands (35d)
The nearly level to hilly Cretaceous Dissected Uplands ecoregion has a greater drainage density than other parts of the South Central Plains.Native vegetation is largely oak–hickory–pine forest. Today, woods and pastureland are common. Water quality in forested watersheds tends to be good, and is better than in pastureland. Streams generally have lower total dissolved solids values and much lower total organic carbon values than the Tertiary Uplands and Pleistocene Fluvial Terraces, although turbidity, total suspended solids, and hardness values are slightly higher. Longitudinal stream gradients and Ouachita Mountain influences are greater than in ecoregions 35a or 35c.
Water quality in forested watersheds tends to be good, and is better than downstream of pastureland. Surface waters usually have lower total organic carbon values and slightly higher turbidity, total suspended solids, and hardness values than the Pleistocene Fluvial Terraces. Streams lying in the Muddy Boggy Creek and Blue River watersheds often originate in, and share many aquatic species with, the Arbuckle Uplift ; alkalinity, hardness, and conductivity values are influenced by local springs, and increase westward. Streams in the eastern part of the Cretaceous Dissected Uplands drain the more rugged, lithologically distinct Ouachita Mountains ; aquatic flora and fauna assemblages are influenced by the Ouachitas and are distinct from western streams.
Settlements include Arkadelphia; Hope; Lockesburg; Hugo; Bennington; and Caney. Protected areas include Crater of Diamonds State Park, some portions of Ouachita National Forest, and Boggy Depot Park.
Southern Tertiary Uplands (35e)
The Southern Tertiary Uplands ecoregion of Texas and Louisiana generally covers the remainder of longleaf pine range north of the Flatwoods on Tertiary sediments. The region of Tertiary geology is more hilly and dissected than the Flatwoods to the south, and soils are generally better drained over the more permeable sediments. Soils are Ultisols and Alfisols with silt loam to loamy sand textures. The Pliocene-age to Eocene-age geology contains a variety of siltstones, sandstones, and calcareous and acidic clays.Historical vegetation was dominated by longleaf pine–bluestem woodlands, but a variety of forest types were present, including shortleaf pine–hardwood forests, mixed hardwood–loblolly pine forests, and hardwood-dominated forests along streams. On more mesic sites, some American beech or magnolia–beech–loblolly pine forests occurred. Some small, scattered prairies with many rare plants are associated with areas of calcareous clay soils. Some sandstone outcrops of the Catahoula Formation have distinctive barrens or glades in Texas and Louisiana that contain several rare species. Forested seeps in sand hills support acid bog species including southern sweetbay, hollies, wax-myrtles, fetterbush, insectivorous plants, orchids, and wild azalea; this vegetation becomes more extensive in the Flatwoods. Currently, the ecoregion in Texas and Louisiana has more pine forest than the oak–pine and pasture land cover more typical to the north in the Tertiary Uplands. Large parts of the region are public National Forest land, such as Kisatchie National Forest. The Southern Tertiary Uplands ecoregion also covers the majority of Louisiana's longleaf pine range west of the Mississippi River.
Settlements include Chatham; Clarks; Jena; Pineville; Leesville; Jasper; Lufkin; and Conroe. Protected areas include Jimmie Davis State Park, Big Cypress State Park, Esler Field Wildlife Management Area, Kisatchie National Forest, Alexander State Forest, Fort Johnson North Wildlife Management Area, Clear Creek WMA, the southern portion of Sabine National Forest, Angelina National Forest and Bannister WMA, Davy Crockett National Forest, and Sam Houston National Forest.
Flatwoods (35f)
The Flatwoods ecoregion occurs on mostly flat to gently sloping Pleistocene sediments. The northern boundary is generally along the Hockley Scarp or the division between Pleistocene and older Pliocene/Miocene formations to the north. Soils are poorly to moderately well drained Alfisols and Ultisols with mostly silt loam textures. They are generally more poorly drained than many areas of the Southern Tertiary Uplands to the north, and tend to be less clayey than in the Southern Subhumid Gulf Coastal Prairies and Northern Humid Gulf Coastal Prairies to the south.This ecoregion once was dominated by longleaf pine flatwoods and savannas, but also supported other mixed pine–hardwood forest types. The longleaf pine community was characterized by longleaf pine over a great diversity of herbaceous species, with the structure and composition varying from the more open forests of the wet savannas to the more closed forests of the dry flatwoods. Savanna wetlands on the Montgomery Formation and prairie areas on the Beaumont Formation were most likely larger in the Flatwoods than in the Southern Tertiary Uplands and Tertiary Uplands to the north. The pine wetland savannas had scattered longleaf pine along with shrubs of sweetbay, wax myrtle, titi, and holly, and a diverse herbaceous layer of grasses, sedges, and, in some places, insectivorous plants and orchids. These wetland savannas are one of the rarest habitat types in Texas with only a few small fragments receiving any protected status. Other similar sites have been greatly modified or have become overgrown and less diverse.
Flatwood landscapes are characterized by pimple mounds, small hillocks that are abundant across the flats. On steep slopes, along streams and other areas where fire was less frequent, forests contained loblolly pine, sweetgum, white oak, southern red oak, willow oak, blackgum, and hollies. Although greatly reduced from its original extent, longleaf pine continues to characterize a significant portion of the area. Beech–magnolia was not extensive, occurring in narrow areas along some streams and mesic slopes.
This region is warmer, wetter, flatter, less dissected, and lower in elevation than the Tertiary Uplands and Southern Tertiary Uplands to the north, with a greater presettlement fire frequency. Streams are low gradient and sluggish. In the eastern part of the region near the boundary with the Red River Bottomlands, more loess occurs, the landscape becomes more dissected, and it supports a mixed hardwood–pine forest. Almost all of the Big Thicket National Preserve is within this region. The area has a long history of modification, particularly by the lumber, railroad, and oil and gas industries that contributed to boom and bust cycles of development and occupance.
Settlements include Moss Bluff; DeRidder; Lumberton; Atascocita; Humble; and The Woodlands. Protected areas include Chicot State Park, Marsh Bayou Wildlife Management Area, West Bay WMA, Big Thicket National Preserve, and Kirby State Forest.
Red River Bottomlands (35g)
The Red River Bottomlands contain the floodplain and low terraces of the Red River within the South Central Plains. The region occurs in Texas, Oklahoma, Arkansas, and Louisiana, and includes the highly meandering main channel of the Red River, oxbow lakes, meander scars, ridges, and backswamps.The Holocene alluvium associated with Red River deposition developed well to somewhat poorly drained Vertisols and Entisols with clayey and loamy, reddish-brown, neutral to calcareous surfaces. The lithology contrasts with the Pleistocene terrace deposits of Pleistocene Fluvial Terraces, and the Tertiary sediments of the Tertiary Uplands. Natural vegetation of the bottomland hardwood forests included trees such as water oak, sweetgum, willow oak, southern red oak, Nutall oak, honey locust, water locust, eastern red cedar, blackgum, blackjack oak, overcup oak, river birch, red maple, green ash, and American elm. There are also some plant distribution differences between the floodplains of ecoregions 35g and 35b. Western species, such as bur oak and Durand oak, were native to the Red River Bottomlands but were typically absent from the Mississippi Alluvial Plain.
Currently in the Red River Bottomlands, most of its natural woodland has been cleared for cropland and improved pasture, although some woodland still occurs in very poorly drained and frequently flooded areas. The broad, nearly level bottomlands are often dominated by agriculture, with more cropland than other floodplains of the South Central Plains. In Oklahoma, The main crops are soybeans, grain sorghum, alfalfa, corn, and wheat; In Texas, soybeans, sorghum, wheat, and cotton; and in Louisiana, cotton, soybeans, corn, wheat, and rice, with some sugarcane in the southern portion. The Red River carries high silt loads and is almost continuously turbid compared to other rivers of the South Central Plains, although silt load has lessened in Louisiana with the construction of the river's lock and dam system.
The Red River historically carried high silt loads and was almost continuously turbid compared to other rivers of Ecoregion 35. With the construction of the lock and dam system throughout its extent in Louisiana, silt load has lessened. The Louisiana portion of the Red River Bottomlands shares similarities in natural vegetation and other biota, hydrology, and land uses with parts of the Mississippi Alluvial Plain.
Settlements, all in Louisiana, include Shreveport; the eastern part of Natchitoches; Alexandria; Cheneyville; and Bunkie. Protected areas include Spring Bank Wildlife Management Area, Soda Lake WMA, John Franks WMA, Red River National Wildlife Refuge, Loggy Bayou WMA, Bayou Pierre WMA, Elbow Slough WMA, Grand Cote NWR, Lake Ophelia NWR, and the Acadiana Conservation Corridor.
Blackland Prairie (35h)
The level to rolling Blackland Prairie characteristically has dark soils derived from underlying Cretaceous marl, chalk, and limestone. Prairie was common or dominant during and shortly after the Hypsithermal Period in the middle of the Holocene Epoch. By the late 18th century, the Blackland Prairie was a mosaic of woodland, savanna, and prairies. Today, the fertile soils of the Blackland Prairie are mostly used for pastureland, woodland, and hayland. Only a few prairie remnants still occur and are mostly limited to the thin, droughty soils of cuesta scarps.Settlements include Gurdon, Prescott, McNab, Ozan, Saratoga, and Rocky Comfort. Protected areas include Terre Noire Natural Area Wildlife Management Area, Ozan WMA, Hope Upland WMA, Rick Evans Grandview Prairie WMA, and Raymond Gary State Park.

Most mature trees have been cleared and the layer of leaf litter, with decaying matter enriching the soil, has begun to wash away with recent rains.]The majority of the commercial timber growing and wood processing in the state of Texas takes place in the Piney Woods region, which contains about of commercial forestland.
National preserve
One National Preserve, the Big Thicket National Preserve, in the southern part of the Texas portion of the Piney Woods region, currently consists of fourteen named, non-contiguous units scattered across a wide area bounded roughly by Pine Island Bayou in Hardin County, Texas to the south, the Neches River bottom to the east, the Trinity River to the west and Steinhagen Reservoir to the north. The preserve contains ten distinct ecosystems according to the National Park Service. Big Thicket National Preserve is one of two UNESCO Biosphere Reserves in Texas. The preserve has also been listed as a Globally Important Bird Area by the American Bird Conservancy. The preserve was established in 1974 under 16 U.S. Code § 698 - Big Thicket National Preserve "...to assure the preservation, conservation, and protection of the natural, scenic, and recreational values of a significant portion of the Big Thicket area in the State of Texas..." Since the preserve's inception, the Conservation Fund has helped to increase the amount of protected acreage by.Protected and public lands

Folklore
The Piney Woods Region of the four state area is a noted area for Bigfoot sightings; with many legends dating back to pre European settlement. One such noted legend is the story of the Fouke Monster of Southern Arkansas; documented in the 1972 film The Legend of Boggy Creek. The area according to references lists this area to be the third highest in North America for these such sightings.Melanistic (black) cougars, another probable cryptid, have been noted by residents.
