Boerne Chapter

Preservation: Challenge Or A Piece Of Cake

By Delmar Cain

May is preservation month in Boerne. There will be no better time to ponder the unique and beautiful place in which we live and the challenges in preserving it. Admittedly most of the events of the month will focus on historical buildings, local family and commercial history and important historical events. But I am sure that the Boerne Area Historical Preservation Society would not begrudge my attempt to focus a bit of attention on the natural beauty of the Hill Country that along with the fertility of the soil attracted the settlers who began arriving in the nineteenth century. It is worth remembering that some of our oak trees were mature when Stephen F. Austin took over his father’s land grant in 1821.

A few weeks ago Wilt Shaw and I had the opportunity to walk along the west side of Cibolo Creek opposite the Cibolo Nature Center along the boundary of the Herff Farm. Even though our area (until last week) had received only a thimbleful of rain for the past eight months the wildflowers and native trees were doing their best to provide blossoms and fruit. We saw a cedar sage (Salvia Roemeriana) touting its small red blooms, white prickly poppies (Argemone albiflora) delicately waving in the breeze, and the big red sage (Salvia pentstemonoides), planted and fenced in 2004 – 2005 by Bill Ward and Ralph Lay, putting up new stalks and looking healthy for its show time in late summer to early fall.

The white prickly poppies were scattered in the fields that had once been planted with crops. Before being farmed the fields had been cleared of their native plant and tree inhabitants. The plowed rows, although not plainly visible because of the grasses, reveal themselves through the shock absorbers on your vehicle. For our more mature citizens mdash; think rub board. Usually found in waste places and open grassy fields and often on a noxious plant list, the white prickly poppies returned uninvited when the farming stopped.

The cedar sage was located along the fence in the shade of a large hackberry tree that stood where the field sloped down to the creek. Probably the cedar sage was in an area that had never been cleared. It and its antecedents could have occupied that location when bison still rambled across the plains and long before Ferdinand Herff first purchased the land in 1852.

The big red sage on the sloping banks of Cibolo Creek is there because of Bill Ward, who was intrigued by the story of a plant considered lost and then rediscovered. It may have been widespread at one time, but now exists in the wild in only a few discrete and naturally protected areas. Bill wanted to help it make a comeback because for whatever reason — deer, livestock, farming or adaptability—its existence in the wild is precarious and it will need care and protection to survive.

Three plants located within 100 yards of each other and yet three different stories about preservation. The white prickly poppy takes care of itself—no preservation necessary. Farmers didn’t want it in their cultivated fields but probably didn’t consider it enough of a nuisance to chase it into the areas which could not be cultivated. And if your neighbor didn’t farm, you would have had a tough sell motivating him to eradicate his white prickly poppies. Sure it’s prickly, but it has a nice flower—almost sounds like a rose. So when farming stopped on the Herff Farm, the progeny of the white prickly poppy, along with a probably better known but unrelated rough character, the bull nettle (Cnidoscolus texenus), opportunistically took up residency in the abandoned field.

Most of the time the cedar sage grows in the shade and often along the edge of a canyon. Its place along the fence line and under the old hackberry meant that it might never have been disturbed by human activity. Because of its proximity to the fence this plant might have received some protection from the white-tailed deer and the axis deer (which apparently having displaced the antelope on the playground, indicates a possible preservation failure). The cedar sage, a perennial, was situated right where it was expected to be. And like most of our native plants, as long as its habitat is not changed, the cedar sage will continue to show up year after year. But here is the caveat. If there is anything that we residents like to do, in addition to watching high school football, it’s cranking up our riding mower and changing habitat.

The third plant, the big red sage, which exists in the wild in very limited numbers, has a history of being lost and found, dating from the collection of its first specimen by Ferdinand Lindheimer in 1845. (For the full story and a picture of big red sage read Bill Ward’s two articles—Big Red Sage Near Boerne, Then and Now—October 2009 and More Big Red Sage Found in the Texas Hill Country—December 2010 under “Publications” on the Boerne NPSOT website: http://www.npsot.org/wp/boerne/). When he planted rosettes along the Cibolo Creek, Bill Ward was attempting to reestablish the big red sage in a habitat resembling that in which it had originally grown. The fact that it is found in such small numbers in the wild means either that it was never widely distributed or it has had difficulty with habitat changes. In either event vigilant human care will be necessary for it to succeed. The plant’s propagation from the seeds of a wild population in 1987 allowing plants to now be raised at botanical centers and in private gardens probably means that it will not go extinct. But preservation in the wild is far from certain.

So from my vantage point, the moral of this story is that preservation of the natural beauty of our area like the preservation of “family values, historic buildings, objects and places” must be considered on an individual basis. It depends on what we are trying to preserve—just as with the plants. Some things will do just fine regardless of what we do, most things will do just fine as long as we keep “the mower and the herbicide in the garage” and some things are going to need all the help we can muster.

About the Region

New Braunfels, the location of our Fall 2024 Symposium, straddles both the Edwards Plateau Ecoregion and the Blackland Prairie ecoregion. Interstate 35 divides the city of New Braunfels; its path through the city closely parallels the boundary of these two ecoregions, with the Edwards Plateau on the west side and the Blackland Prairies region to the east. 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 four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
