A Recent Plant Rescue Success Story

by Jackie O’Keefe

We in the plant community have had unusual good fortune the past couple of months. The owner of a sizeable property gave permission for numerous groups to access his land for plant rescues before he began building. He had responded to urging by neighbors – NPSOT members among them – to grant this access. To say that this property had a lot to offer would be an understatement. And the months-long access has allowed us to collect seeds and plants of the Balcones Canyonlands habitat to pass along to BCP preserve areas and replant in native plant gardens across our area. Again, it’s hard to overemphasize the opportunity it has presented to re-home plants from this habitat. In general, we are not talking about rare species, but shrinking habitat focuses our concern.

There are philosophical arguments here about the utility of plant rescues. Just what are we saving and are we trying to put the ocean in a depression in the sand…? Our rescue efforts are grassroots (Native Grasses!!) attempts to maintain the flora of our protected Balcones Canyonlands Preserve and Native Prairies acreages and to broaden the availability of the native species of our region – Blacklands Prairies and Edwards Plateau. This latter aim is accomplished by a couple of mechanisms. One is the quite small inroad of having volunteers introduce the rescued species in their own landscapes and the public landscapes they help support via the conservation organizations where they volunteer. The other is by encouraging the cultivation and sale of the rescue species in our local plant nurseries – another incremental process. Any more on that discussion, I’ll happily leave for another day. Habitat is slipping away in the meantime.

The recent rescue efforts were spearheaded by a CAMN (Capital Area Master Naturalist) member and Austin Balcones Canyonlands people, and enthusiastically joined by Austin NPSOT, Balcones Canyonlands Master Naturalists, Williamson’s Good Water Master Naturalists, and Williamson NPSOT, among others.

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.
