The Big Pull in Round Rock postponed due to weather

News for The Big Pull that was scheduled for March 7 in Round Rock:

With thunderstorms looking ever more likely for Saturday organizers of The Big Pull are rescheduling the invasives removal to March 21, same time of day and place. WCCF is sending out an email to those who have already signed up. If you haven’t signed up yet, the signup link is below in the 2nd part of this post. Folks are sorry for the reschedule but it seemed like the safer alternative!


The original announcement is below for your convenience (highlighted where info has changed).

The Good Water Master Naturalists are supporting the Native Plant Society of Texas by joining them for The Big Pull! Let’s make an impact during National Invasive Species Week by removing invasive species and supporting healthy native ecosystems at the park by our iconic Round Rock on Saturday, March 7 March 21, 9am-12pm.

Williamson County Conservation Foundation is taking care of sign up since it’s part of their responsibility so we’ll be signing up on their website. If you’re new to volunteering with them, every participant will need to sign the WCCF waiver before participating. (It is good for the rest of the calendar year in case you want to volunteer with WCCF again.) All are welcome, bring friends and family members if they want to join in on the fun.

All the details

  • Link to sign up (includes link to waiver) (WCCF updated the form to 3/21)
  • Date/Time: Saturday March 7, 2026 March 21, 2026 from 9am-12pm
  • Place: Meet at the parking lot next to Brushy Creek trail. Google map link: https://maps.app.goo.gl/QUhi99VbSXMKGTFd8
  • Bring: Gloves, water, sunscreen, snacks if you want them, and basic garden tools for taking out weeds! Dress for the weather that day. Long pants and close toed shoes recommended.

If you have any questions, send an email to wilco-chapter@npsot.org and we’ll put you in touch with chapter member (and master naturalist) Michelle Goerdel.

TPWD Webinar on Jan 21, the Zapata Bladderpod

News from Texas Parks and Wildlife Department’s Wildlife Conservation Webinar Series:

“Reproductive biology and ecology of the Zapata Bladderpod (Physaria thamnophila; Brassicaceae): an endemic to the Tamaulipan thornscrub, USA”

  • Date: Wednesday, January 21, 2026
  • Time: 12:00 p.m. – 1:00 p.m.
  • With:
    • Brenda Molano-Flores – Principal Research Scientist-Plant Ecologist & Conservation Biologist Illinois Natural History Survey, Prairie Research Institute, University of Illinois, Urbana-Champaign
    • Janice Coons – Emeritus Botany Professor; PR Institute Affiliate Eastern Illinois University; Illinois Natural History Survey

The Zapata Bladderpod (Physaria thamnophila; Brassicaceae) is a federally and state endangered species endemic to the Tamaulipan thornscrub of South Texas with documented occurrences in Northern Mexico. In this project we documented the breeding system, flower visitors, reproductive success, and seed germination of this species. From 2022-2024, data were gathered at eleven sites ranging from federal, private, and NGO lands. All the data gathered during this project has expanded our knowledge of the biology and ecology of Physaria thamnophila and can contribute to future reintroduction efforts for the species. The latter is extremely important due to the anthropogenic pressures associated with habitat loss and degradation facing Physaria thamnophila and the Tamaulipan thornscrub in south Texas.

A graduate of The University of Iowa, Dr. Molano-Flores got her Ph.D. in 1997. Shortly after she became a Research Scientist with the Illinois Natural History Survey (perhaps the oldest state scientific survey of the US). Her research focuses on various aspects of plant-insect interactions, threatened/endangered plant species, plant reproductive biology, and grassland ecosystems

Dr. Coons has investigated reproductive biology of several federally listed plant species including ones in Florida, Arizona, and Texas. She has studied two other Physaria species. She also has developed protocols using seeds to overcome seed dormancy, and then propagate plants to be transplanted to their natural habitats. Her degrees include botany and horticulture, which gave her the necessary skills for these restoration approaches. She retired as an emeritus professor from Eastern Illinois University in 2014.
