Practical information to identify and manage non-native, invasive plants and animals
The Quiet Invasion:
A Guide to Invasive Species of the Galveston Bay Area
Managing Invasives
Prevention
The most cost effective way to control the spread of invasive species, is to prevent their introduction.

Two regulatory agencies, the Texas Department of Agriculture (TDA) and the Texas Parks and Wildlife Department (TPWD), maintain lists of prohibited exotic species for the State of Texas. Exotic species listed as prohibited by the agencies cannot be imported, sold, or possessed by individuals without a permit from the agency. Violations are punishable as a Class C misdemeanor and can be reported to a local TPWD law enforcement office.

Not all of the species included in this web-based field guide are prohibited in the State of Texas, but those that are prohibited are identified as such.

Additional information regarding species listed as prohibited by state and federal agencies can be found at:
Control
Invasive plant and animal species that are already established on public or private lands or in surface waters can be controlled with a number of methods.

Control techniques such as physical removal of the plant or animal can be labor intensive and costly depending upon the extent of the invasion and the area of land or water that require attention.

Control techniques such as the use of fire, chemicals, and biological control agents can be dangerous to humans and the environment and may require special authorizations and the expertise of a permitted professional.

An expert in the control of invasive species should be consulted before applying invasive species control techniques.
