Journey to the Northeast to learn about a diversity of ecosystems

**ARCHIVED POST **

Get ready to venture to Northeast Texas this fall and learn about a part of our state that’s more than just the corner doorway for travelers. It’s a crossroads for ecosystems of all makes and models.

Texarkana is the destination of the Society’s 2014 Fall Symposium. Set for October 16-19, the symposium will focus on Northeast Texas: Diversity of Ecosystems.

Registration will open in late summer, so please save the date.

Located literally on the border of two states, “Twice as Nice” Texarkana is actually two cities—Texarkana, Texas, and Texarkana, Arkansas. Less than an hour to the northwest is Oklahoma and about a half-hour to the south is Louisiana. It’s truly a four-state region.

Not only do those four geopolitical state lines converge in or near Texarkana, but several ecological regions also converge here. Two of Texas’ ten vegetation zones—Piney Woods and Post Oak Savannah—bisect Texarkana’s Bowie County diagonally and ecosystems converging all around include pine and hardwood forests, grasslands, deserts, swamps and even subtropics.

The Symposium Planning Committee is busy arranging speakers, field trips and breakout sessions to reflect the diverse ecosystems found within the four-state region of Texarkana. Field trips are planned to all four states, and speakers from all four states are being recruited. More details will follow. The planning committee is composed of members from all five chapters from the region: Four Corners (Texarkana), Caddo Wildflower (Linden), Lake Country (Mt. Pleasant), Tyler and Northeast Texas (Longview).

Our symposium headquarters and the host hotel are newly built, both going online in late 2012. Headquarters will be the Texarkana Convention Center. Located at 4610 Cowhorn Creek Road—on the Texas side of Texarkana, just off Interstate 30—the spacious, environmentally friendly convention center boasts the prestigious LEED certification by the U.S. Green Building Council.

Conveniently adjoining the convention center is the host hotel, the Hilton Garden Inn Texarkana, also green-built. Each Hilton room offers a mini-fridge, microwave oven, coffee pot, flat-screen TV, free Wi-Fi and more. Shopping and dining abound within a mile or two of the convention center and hotel, though most meals will be provided with the symposium registration fee.

Texarkana is located on Interstate 30, about 175 miles east of Dallas (just more than 2 1/2 hours) on the border with Arkansas. The convention center and host hotel are located 13 minutes from Texarkana Regional Airport, which is served by American Eagle Airlines, and 9 minutes from Amtrak’s Texas Eagle station on the Arkansas side.

A block of rooms has been reserved for $89 per night plus tax for single or double rooms for up to two people Reservations may be made now by calling the hotel at 903.792.1065, or register on-line.  The hotel address is 2910 S. Cowhorn Creek Loop.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
