Law would require disclaimer on invasives list

**ARCHIVED POST **

A proposed new Texas law (HB 338) would require any public entity other than the  Texas Department of Agriculture that produces a list of noxious or invasive terrestrial plant species growing in this state to include a disclaimer.

The following disclaimer would be required on all printed material made for public distribution including newspapers, trade publications, circulars or Internet websites:

“This plant list is only a recommendation and has no legal effect in the State of Texas. The Texas Department of Agriculture has sole authority to label terrestrial plants as noxious or invasive.”

State Rep. Jimmy Don Aycock, who represents Burnet, Lampasas and part of Bell County, sponsored the bill, which has not yet gone to committee. The only official, legally binding list of terrestrial invasive plants is the list maintained by the Department of Agriculture; the Texas Parks and Wildlife Department is responsible for the aquatic invasive plant list.

Some people get confused and think other lists might also be official and legally binding when they are not. This bill will help clear that up, according to a spokesman in Aycock’s office. Native plant societies and garden clubs could still put out their lists without disclaimers. Government entities and agencies must use the disclaimer. He specifically mentioned the Lady Bird Johnson Wildflower Center as possibly confusing people.

The bill was actually written by the Texas Nursery and Landscape Association (TNLA), according to the spokesman.

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.
