Get to Know Austin’s Conservation Wildlands

Dr. Kevin Thuesen, Program Manager with the City of Austin’s Water Quality Protection Lands, talked with KXAN about converting the City of Austin’s wildlands back to their native state. In the video, you’ll learn about prescribed burns on the lands and how native people used the native Prickly Ash or toothache tree.

You’ll also learn about their efforts to get rid of invasive plants like King Ranch Bluestem (KR Bluestem). (Sounds like a job for your friendly-neighborhood Amazing Invasive Hunter Man.)

The Austin conservation wildlands include the Balcones Canyonlands Preserve (BCP), which includes habitat for the endangered Golden Cheek Warbler, and Water Quality Protection Lands (WQPL) that include lands that help to feed the Barton Springs Aquifer.

Water is so important to Central Texas. The Texas Water Resources Institute describes how protecting our land helps to protect our water. (The Colorado River Alliance also helps to keep the water in Lake Travis clean.)

I’ve had a chance to go on many hikes and volunteer with Austin’s Wildland Conservation Division. Here are a few of the posts on my past adventures on the BCP and WQPL:

Spring is the best time to take a guided hike on the water quality lands. Plants are green. Flowers are blooming. Water’s flowing. There’s a lot of life, birds and insects.

Normally, the BCP and WQPL lands are not open to the public to protect the land for endangered species and water quality, but there are many hikes that you can take with experienced guides to enjoy the lands and learn about the diverse plants and animals that inhabit these unique ecosystems.

In the Balcones Canyonlands Preserve, April guided hikes include:

  • 4/26 – Finding Austin’s Endangered ones

On the Water Quality Protection Lands, April guided hikes include:

  • 4/10 – Scenic Springs and Hidden Vistas
  • 4/11 – Onion Creek Exploration
  • 4/11 – Sunset at Slaughter Creek
  • 4/24 – Big Views at Little Barton
  • 4/25 – Insect Safari

Sign up for a guided hike with the Wildland Conservation Division.

You can also help to remove the Invasive Star Thistle and volunteer for other activities on Austin Wildland Conservation Lands.

To learn about upcoming events, be sure to join the Wildland Conservation Division email list to get the latest updates from Ms. Amanda Ross, volunteer coordinator with the City of Austin.

I hope you’ll have fun with one of these hikes this spring!

Your friend,

Adventures with Austin’s Invasive Species Corps

Last weekend, I joined the Austin Invasive Species Corps to identify locations of Chinese Privet (Ligustrum sinense), an invasive species invading in the Long Canyon portion of the Balcones Canyonland Preserve (BCP).

I was happy to talk again with Mr. Chris Warren, a biologist with the BCP, and see the area that we helped to clear last year in my video, Titanic Struggle with Chinese Privet Ends with their Doom. (I’ll post another great video interview with him soon!)

Commander Ben and Biologist Chris Warren examine a small Chinese Privet.

It was nice to see a lot of native plants starting to grow back in the open spaces that the Chinese Privet plants used to occupy. We had pulled up a lot, but more were starting to creep back in and there were other areas too where the Ligustrum overran the native plants. (Sometimes the biologists in our group would call Chinese Privet by its scientific name, Ligustrum.)

Pulling up Chinese Privet with a weed wrench.

We used special weed wrenches to hand pull as much Chinese Privet as we could find. These heavy tools help to pull up the plant, roots and all, otherwise it could grow back from a stump.

It was a fun day filled with hunting invasives, hard work, and listening also to some wonderful presentations from many different people who are experts in the field of invasive species.

Know your invasive species: Chinese Privet

Small Chinese Privet plant (But they get much bigger!)

Chinese Privet is a woody bush with green leaves that break off easily and has lots of shoots growing out from the stalk.  It can sometimes be confused with the following native plants:

  • Elbow bush (Forestiera pubescens)
    How to tell them apart: Elbow Bush has branches that grow at 90 degree angles
  • Yaupon (Ilex vomitoria)
    How to tell them apart: The Yaupon has a tooth edge leaf instead of smooth edge leaf like the Chinese privet.

Unfortunately, Chinese Privet invaded the lower area of Long Canyon where it crowded out the native plants to create a monoculture.  Seeds from “Godzilla” sized Chinese Privet that were planted in the landscapes of homes up on a ridge, washed downhill, grew, and quickly multiplied.  This process happens over and over again when it rains and when birds carry the seed berries too.

In Asia, Chinese Privet’s native home, it stays in check because it has to contend with disease, parasites, and wildlife “eaters”.  Here in the U.S., Chinese Privet is essentially free of predators, and this allows it to spread aggressively.  Even our deer don’t like to eat it!  They prefer our native Texas plants instead.

As a non-native and pioneer species, this invasive plant can grow and spread quickly.

So why is it a problem if Chinese Privet establishes a monoculture in our area?

Know your Endangered Species: Golden cheeked warbler

Well, it all has to do with water and the cute…and endangered…Golden-Cheeked Warbler.

The Golden-Cheeked Warbler, is a native bird and it uses the bark of the Ashe Juniper (Cedar) tree to make its nests.  These birds eat the larva of moths and butterflies that live on the Texas Live Oak trees.  Unfortunately, the Chinese Privet hogs the water and crowds out the the Cedars and the Oaks, and this eliminates the habitat and food for the Warbler.

This is especially troubling because the Golden-Cheeked Warbler is the only bird species with a breeding range confined to Texas from Palo Pinto County southwestward along the eastern and southern edge of the Edwards Plateau to Kinney County. The Balcones Canyonland Preserve is part of the Warblers’ habitat.

By clearing the Chinese Privet, we hope to create more habitat and food for the Golden-Cheeked Warbler.

Another opportunity to clear invasive species next month

Mark your calendars on Saturday, September 29, when the Austin Invasive Species Corps will get together again for a land management workday to fight against invasive plants in a new area of Long Canyon. This time, they’ll grapple with a team of two villains:

This is your chance to be an Invasive Hunter in action to battle against invasive species and help save the Golden-Cheeked Warbler!

Many thanks to Ms. Louise Liller, volunteer coordinator for the Austin Water Utility’s Wildland Conservation Division; Mr. Chris Warren; Austin biologists Mr. Darrell Hutchinson and Mr. Matt McCaw; and the valiant voluteers of the Austin Invasive Species Corp for hosting this event and making a difference for our endangered songbird and our native ecosystem.

Your friend,
Ben
