Hill County Rest Area Monarch Waystations

Seeking Volunteers

On Saturday February 17 there will be a workday at the Hill County rest area monarch waystations. This effort is part of a NPSOT project to maintain monarch waystations along Interstate 35. We will start on the southbound waystation at 9:00 am. Please come and go as your schedule allows. Most of the work will be weeding and pruning. We recommend that you bring the following items if you have them (trash bags and some tools will be provided): 

  • Gloves
  • Hat and Sunscreen
  • Knee pads or kneeling pad or towel to kneel on
  • Weeding tool, Pruners and Loppers
  • 5-gallon bucket
  • Mask if desired

The Hill County Southbound Rest Area is located at Exit 362A on Interstate 35, (about 5 miles south of Hillsboro, near Abbot). Access from Texas Interstate 35 is in the southbound direction only. If you are coming from the south (Waco) go past the rest area and take the first exit and do a U-turn, get back on the interstate going south and take Exit 362A.

The Hill County Northbound Rest Area is located at Exit 362A on Interstate 35, (about 5 miles south of Hillsboro, near Abbot). Access from Texas Interstate 35 is in the northbound direction only. If you are coming from the north (Dallas) go past the rest area and take the second exit and do a U-turn, get back on the interstate going north and take Exit 362A.

Other upcoming 2024 Saturday workdays at the Hill County Rest Area Monarch Waystations will be on March 16, April 20, May 18, June 15, July 20, August 17, September 21, October 19, November 16, and December 21. 

Please email Betsy Farris or Kay Jenkins to be added to the contact list in case there are changes in the schedule or other updates.

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.
