Please join us via Zoom on the date as we will not be live streaming or recording. You can join us early at 6:30 for social time and troubleshooting connection.
Carolyn Oldham and Jerri Kerr are longtime members of the Prairie and Timbers Audubon Society of Collin County. They have traveled extensively in North America to see and record the many interesting and unique species found here. Both are avid gardeners, dedicated to making their backyards welcoming habitats for birds, butterflies and bees. Hummingbirds hold a special interest for Carolyn and Jerri, and they love sharing their knowledge of this unique and magical bird.
After registering, you will receive a confirmation email containing information about joining the meeting.
Please note, it is our understanding that there is no limit to registrations, but we currently do have a plan with a limit of 100 attendees. Therefore, you’ll be in a “waiting room” until we can let you in. Once we have reached 100, we’ll let the waiting room know, but continue to hang out to see if anyone disconnects.

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.
