Austin Passes Invasive Species Resolution

The Austin City Council recently approved a resolution directing the City Manager to develop an Invasive Species Management Plan for city owned land. The resolution encourages community collaboration and innovation in protecting and restoring the city’s natural resources, and will mitigate the negative impacts invasive species have on Austin greenspaces. Austin may be first city in Texas to create an invasive species resolution – View Resolution.
TPWD Launches Attack on Invasives

The Texas Parks and Wildlife Department recently launched a public awareness campaign asking people to help control one of the most dangerous invasive aquatic species the state has ever known, giant salvinia. TPWD has been working with the Lady Bird Johnson Wildflower Center and Sherry Matthews Advocacy Marketing on the campaign, which will communicate the message "Hello Giant Salvinia, Goodbye Texas Lakes". The campaign includes floating buoys, gas station pump toppers and billboards at or near four targeted lakes: Caddo, Toledo Bend, Lake Conroe and Sam Rayburn.

The campaign drives traffic to, where visitors can find a wealth of information about giant salvinia and other invasives. The 2010 salvinia campaign marks the start of an umbrella effort that will feature other invasive plants and animals in the future – View News Release.

Invasive Spotlight: Field Brome
(Bromus arvensis)

Field brome is a winter annual producing dense, low leafy growth in the fall. Culms are erect and solitary and the inflorecence is panicle. It has 1-8 spikelets on each lower branch producing seedheads in late spring or early summer.

This plant displaces desirable vegetation if not properly managed. It grows vigorously under high fertility and growth usually starts earlier than most native Spring grasses often smothering native grasses and forbs. It is an excellent seed producer and can maintain itself as a reseeding annual.

Field brome usually occurs in dry habitats, such as roadsides, waste places on sandy or rocky soils.

Citizen Scientist of the Month: Lonnie Shockley

Lonnie Shockley of the newly formed Balcones Invaders satellite is our citizen scientist of the month. Lonnie has been with the Invaders of Texas program for a few years working with the San Antonio Invaders satellite. He was the first in his training class to reach the goal of 50 observations to earn a new GPS. Congratulations, Lonnie.

Lonnie has gone above and beyond the call of duty by becoming the satellite leader of the Balcones Invaders. With fellow citizen scientists, Judith Shockley and Cheryl Hamilton, they conduct their own citizen scientist training workshops. Lonnie is a classic example of the Invaders of Texas citizen scientist model, becoming familiar enough with the program to train others. Keep up the great work, Lonnie!
