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

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
