Wire and fire: a history of ecosystems management

**ARCHIVED POST **

Today, the Kerr Wildlife Management Area serves as a prime example of good range stewardship based on sound ecological principles. However, historical accounts reveal a vastly different scenario.

Donnie Frels, area manager for the Kerr WMA, will be one of the keynote speakers at our Fall Symposium.

His presentation documents the decisions, practices and tools responsible for the transformation of this property from native grassland savannah, to cedar brake, to a healthy ecosystem producing a diverse array of desirable products.

“The term ecosystems management is presently utilized throughout the conservation lexicon to represent a broad array of methodologies designed to produce a variety of desired products. Unfortunately, many biologists and range managers fail to fully understand the many variables, both natural and man-made, which influence this complex process through time.

“Although Leopold’s tools of wildlife management are widely accepted, the use (or misuse) of these tools can lead to poorly managed and inefficient systems producing undesirable products.

“Often times, a manager’s first response is to begin treating symptoms of the problem without identifying the actual cause. In order to fully realize the ecological potential of a site, managers must first understand the conditions and circumstances which led to its current state.”

Donnie Frels will be one of many speakers at Symposium 2012 at the YO Ranch Motel & Conference Center in Kerrville. Online registration has now been opened for the symposium which will be October 4-7.  Overall theme for the symposium is the changing landscape of the Texas Hill Country.  Also included are workshops, exhibits and field trips to areas of interest.

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.
