Cost of the two-day conference is $75 and includes all meals, break refreshments and tour transportation costs. Hotel rooms are available at the Inn on Barons Creek for $99 per night under the Bennett-TAMU group code.

The Women’s Natural Resource Management Conference is funded by the Ruth and Eskel Bennett Endowment, said Dr. Larry Redmon, co-chair and Texas A&M AgriLife Extension Service Bennett Trust specialist.

The women’s conference is an extension of the Bennett Trust Land Stewardship Conference, which has been held three times in Kerrville, Redmon said.  “More and more women are becoming landowners through inheritance and other means, and we want to help these women be a success in the management of their natural resources,” he said. “By offering a ladies conference, we hope women will feel more comfortable with attending and participating. We also want to encourage mothers to bring their daughters; it is a generational thing.”

“Everyone involved in the planning process is excited about our new Edwards Plateau Land Stewardship conferences,” he said. “And thanks to the Bennett’s generosity, this will be a unique learning opportunity for all of us for years to come.”

The Initiative

In 2010, the Upper San Marcos River was cited on Texas Commission on Environmental Quality’s 303(d) list of impaired waterways, for exceeding total dissolved solids (TDS) water quality standards. The River is currently in compliance with the Clean Water Act Standards, but several pollutants have been identified as a concern.

The San Marcos Watershed Initiative (SMWI) began in 2012 as a multi-year process of research and information gathering with the end goal of implementing a community approved and federally accepted Watershed Protection Plan for the Upper San Marcos River. Read more.
