March 2022 Meeting – Dr. Carly Aulicky, North Texas Director of Outreach and Stewardship of NPAT, “Finding Balance in a Changing Landscape: Prairie Biodiversity and Invasive Species ”

**ARCHIVED POST **

Join us for our March meeting featuring Dr. Carly Aulicky, the North Texas Director of Outreach and Stewardship of NPAT, speaking on “Prairie Plants and Invasives”.  We’ll meet on Monday, March 21st at 6:30pm for social time and start our program at 7:00pm.  https://us02web.zoom.us/j/89376637722?pwd=ay9uY1dZVlN4RGJBNkNEeG9ISC9ZQT09

 

Prairie ecosystems are adapted to grazing and fire, and these disturbance events are necessary to prevent prairies from becoming woodland and help maintain prairie biodiversity. With agricultural conversion and urban expansion, much of North America’s prairies have been lost and many remain in fragments. This has changed disturbance regimes in prairie ecosystems, often removing disturbance events required to maintain diverse prairies. Removal of disturbance and the changing land use around prairies can leave them vulnerable to invasive species establishment. Can a balance be found between maintaining prairie biodiversity and controlling invasive species in a changing landscape and climate?

 

Dr. Carly Aulicky is the North Texas Director of Outreach and Stewardship for the Native Prairies Association of Texas (NPAT). In her position, Carly acts as a resource and spokesperson for management and conservation of native prairies. Carly monitors NPAT properties, works with landowners on conservation easements, holds educational workshops and talks, and coordinates volunteer efforts in programs and projects. Dr. Aulicky completed her doctorates at the USGS Kansas Cooperative Fish and Wildlife Research Unit at Kansas State University in 2020.

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.
