Project Number: 5325-22000-017-13
Project Type: Trust

Start Date: Sep 30, 2000
End Date: Sep 29, 2005

Objective:
1)To develop and evaluate improved benefit/risk assessment methods for invasive species infestations and their control using biologically-based technologies and integrated control methods. 2) To develop ecological data characterizing the biology, distribution and impact of three invasive species (saltcedar, yellow starthistle, and giant reed); and 3) to use biological control agents to reduce their populations to level below critial economic injury levels. Documents Trust with CSREES-IFAFS Log 17987

Approach:
A panel of experts will be used to formulate a whitepaper on the state of biological control risk/benefit assessment. The paper will provide the basis for an interagency workshop to discuss issues and new methods that may be used to improve the regulatory processes. Example cases will be evaluated by a risk/benefit core team which includes biologists, economists and risk assessment specialists. 2) A combination of laboratory, greenhouse and field studies will be conducted to provide quantitative data on the growth characteristics of invasive weeds; the biology and ecology of natural enemies, their target and non-target impacts; and new methods will be developed and applied in integrated weed management & revegetation projects. Three detailed studies areas will be investigated in California, Wyoming and Texas. 3) An area-wide integrated weed management program will be implemented and evaluated with the goal of controlling invasive weeds using biologically-based technologies. Ten implementation sites will be used to introduce natural enemies and to assess their area-wide impact.
