2011 Texas Invasive Plant and Pest Conference

The Texas Invasive Plant and Pest Conference is a professional level meeting including keynotes, concurrent sessions, posters, and symposia designed to serve scientists, land managers, state and federal agencies, local governments, and other professionals with an interest in Texas' invasive species. The conference will be held at the Lady Bird Johnson Wildflower Center in Austin, Texas November 8-10, 2011.

About the Conference

This year's conference will feature over forty oral and poster presentations in the following categories: Leadership and Coordination/Public Policy, Early Detection and Rapid Response, Control and Management, Research, Information Management, and Education and Public Awareness. The conference will also include a Legislative Update by State Representatives Jimmie Don Aycock and Donna Howard, keynote address by Chuck Bargeron, author of EDDMapS, a Caddo Lake Case Study hosted by the Caddo Lake Institute and an update on the City of Austin's Invasive Species Management Plan. On the final day, participants can choose between an EDRR workshop, an Arundo donax field trip on Lady Bird Lake or participate in a Weed Risk Assessment discussion.

2011 Workshops and Field Trip

On the final day, participants can choose between an EDRR workshop, an Arundo donax field trip on Lady Bird Lake or participate in a Weed Risk Assessment discussion.

Invaders Citizen Science EDRR Workshop

The Invaders of Texas program is an innovative campaign whereby volunteer citizen scientists are trained to detect the arrival and dispersal of invasive species in their area and report them into a statewide detection and mapping database. The idea is simple. The more boots on the ground and trained eyes watching for invasive species, the better our chances of responding to new and existing threats thereby lessening or avoiding economic and ecological damage invasive species can cause to native ecosystems. Since its inception in 2005, the Invaders program has hosted 59 workshops and trained over 1,300 citizen scientists. These citizen scientists have logged over 4,300 hours in the field and collected over 13,000 species observations. This workshop will give a broad overview of the Invaders program and provide information about Recruitment, Workshop Structure, Online Training, and introducing the program to Schools.

Arundo donax field trip on Lady Bird Lake

As part of a larger riparian restoration project on Lady Bird Lake, the City of Austin is working to remove invasive species along the lake shoreline. Initial efforts have focused on Arundo donax (giant cane) and volunteers with the Lady Bird Johnson Wildflower Center's Citizen Scientists program mapped the plants in 2010, documenting over 3.5 acres (~8,000 linear ft) along the five mile shoreline. The plants grow primarily on steep slopes, from the water's edge to upland areas, either in monoculture or mixed with native vegetation. While the most effective control option is herbicide application on mature plants (up to 20 ft in height), proximity to the lake's popular hike and bike trail and adjacent desired vegetation required a more targeted approach. A majority of the plants were cut and allowed to re-grow prior to a mid-October herbicide application, thus minimizing the impacts to non-target areas with native vegetation or public trails.

The tour will show a variety of treatment areas, including some patches that were sprayed as mature plants, as well as the other 'cut and re-grow' areas. Two treatment regimes will also be shown, those treated with imazamox alone (very selective, used in areas of mixed vegetation) and those treated with a mix of glyphosate and imazamox (used in monoculture stands).

In addition to the Arundo work, the field trip will showcase the City's efforts (in conjunction with the Lewisville Aquatic Ecosystem Research Facility) to establish native macrophytes on the lake. Participants will view sites where founder colonies of native plants have been established within a variety of herbivore exclosures, as well as areas of the lake where these plants have spread well beyond the original protection.

Weed Risk Assessment Roundtable

At the 2009 Texas Invasive Plant and Pest Council the Weed Risk Assessment committee chose to adapt the California Invasive Plant and Pest Council’s Criteria for Categorizing Non-native Invasive Plants that Threaten Wildlands and use the adapted version as a Weed Risk Assessment tool for Texas. Since then, the Criteria have been adapted to fit Texas parameters and approximately 25 species have been assessed. Recently a desire to expand the Texas Department of Agriculture’s Noxious Weeds List has been shown by state agencies, resource managers, and environmental groups across the state. This roundtable discussion will discuss the adaptations made to the Cal-IPPC Criteria, the species that have been assessed, and how new species can be added to TDA’s noxious weed list.
