TIPPC Takes Action Against Japanese Climbing Fern

This March, the Texas Invasive Plant and Pest Council (TIPPC) submitted a formal request to the Texas Department of Agriculture (TDA) to add Lygodium japonicum (Japanese Climbing Fern) to the state Noxious and Invasive Plants list.  

This action sets a precedent for adding non-agricultural invasive species, as TIPPCs' request is the first to follow the TDA established protocol. If approved, it would be illegal to  sell or distribute Japanese Climbing Fern without a permit.  This will help control the spread and protect Texas forests.                  


Hello Bastard Cabbage.  
Goodbye Bluebonnets.

Bastard cabbage - Don’t let it if fool you! The bright yellow flowers towering over the blues and reds of our native bluebonnets and Indian paintbrush are an invasive species with an overwhelming presence along Texas' roadways this year.  Rapistrum rugosom (Bastard Cabbage) is taking up space and resources meant for our native wildflowers. This is not going un-noticed by Texans, and there is a rising level of media-coverage and concern over the spread of bastard cabbage.

Zebra Mussel DNA Found in North Texas Lakes

In October, low levels of Dreissena polymorpha (Zebra Mussel) DNA was found in Eagle Mountain, Lewisville, Ray Roberts, Arrowhead, Bridgeport and Caddo Lakes. Levels were not high enough to suggest that colonies are forming, but they do suggest that boaters may be transporting them.  Read More.

Report sighting and always CLEAN, DRAIN, and DRY your boat!

New Invasive Plant Mapping System: CalWeedMapper

The California Invasive Pest Council has created a new online mapping tool, the CalWeedMapper. They are using a different method of mapping distribution, USGS quadrangles, to produce seamless statewide maps. Their data comes from meetings with local experts who mapped distribution, spread and management by USGS quad, and are also linked to the Calflora database.

A user can select a region (a county, a CWMA, a national forest, etc.) to see which species are potential targets for eradication, containment or surveillance based on their distribution. This design is intended to support regional strategic planning at different scales.


Calling all Cogongrass Warriors!

The University of Georgia's Center for Invasive Species and Ecosystem Health has updated their website so that Cogongrass flowering sightings can be easily reported. Cogongrass has started to flower along the Gulf Coast and in Florida and reporters can enter whether the observed plant was flowering or seeding. This information will help to determine when seed formation begins.

This will greatly aid in learning where flowering is occurring and how it progresses, thus preparing others to anticipate flowering for survey and treatment purposes.  Click here to report sightings and view the 2011 flowering map.

Citizen Science Workshops

Sentinel Pest Network & Invasive Species Workshops
These workshops supplement the Invaders of Texas program by training citizen scientists to identify and report invasive pests of regulatory concern like Emerald Ash Borer and the Cactus Moth while they are out looking for invasive plants. The morning session will cover non-native, invasive pests, and the afternoon session will be a refresher course on non-native, invasive plants that occur in your area.
