Join Us for the Big Pull

Top Observations from the Invasive Species Bioblitz

Please join us for the invasive species Big Pull! Let’s make an impact during National Invasive Species Week by removing invasive species and supporting healthy native ecosystems across Texas between Feb. 23 – March 8.

Whether you participate as a chapter, or as an individual, here is what you can do:

Choose a Site

  • Select public or private land (ensure permission has been granted by the land manager or landowner)
  • Not sure how to find your spot? Contact your city or county parks or environmental department for hot spot ideas
  • Check in with a Texas Master Naturalist group to see if they have projects
  • Reach out to area natural area managers, like state parks or nature preserves, and county ag extensions

Identify Target Invasive Species

  • Focus on one or more invasive plant species appropriate to your region
  • Confirm species identification before removal. Use this handy list of “Top Offenders” organized by ecoregion

Host or Participate in a Removal Activity

  • Conduct your “Big Pull” any time between Feb. 23 – Mar. 8
  • Chapters may host an organized workday or partner with another group
  • Individual members may work on their own property or other areas (as long as permission is given)

Follow Safety & Disposal Best Practices

  • Use appropriate removal methods for the species
  • Dispose of plant material according to local guidance
  • Do not transport invasive material off-site unless disposal is approved

Document Your Impact

We encourage you to submit a report here about the type and amount of species you removed to help us get a sense for state-wide impact.
Be sure to take some before and after photos of your work!

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.
