Invasive species management research

The following links go to information about invasive species, a.k.a. weeds

Biological Invasions of Alien Plants in the Interior Columbia River Basin. Basic Biology, by Peter Morrison and George Wooten. A review paper on the extent and costs associated with alien plant invasions, including some factors about the basic biology of their spread, and policital and legal ramifications of their management.

The Knapweed Chronicles, Advanced Knapweed Biology 232 and Skills Lab. Riveting!!

Old Ways, New Ways. A comparison of the old and new ways of managing invasive species.

Boulder Creek on the Okanogan National Forest. - A case study of a weed management action gone wrong, including a photographic survey and letters to the National Forest Supervisor describing the problem.

Weed Sprayers Gone Bad. McFarland Creek - Another case of a weed management action gone wrong, along with an essay on herbicide misues.

Risky Business: Invasive species management on National Forests - A review and summary of needed changes in current plans, policies and programs, by George Wooten and Marlene Renwyck. To be successful, a program of invasive species management should offer long-term sustainability, clearly stated goals, understanding of biological principles, adaptability and accountability. In the rush to secure program funding, agencies have missed opportunities for sound alternatives of invasive species.

Using the World Wide Web to learn about Integrated Pest Management (IPM). This paper gives a working definition of IPM to guide in evaluating programs which claim to use IPM. Although IPM was originally intended as a means of pesticide reduction, the concept of IPM has been abused to justify increased herbicide.

Many herbicide-intensive programs claim to use IPM, but obviously with as many accidents each year, they can't all be doing it right. IPM was originally intended as a means of pesticide reduction, but more recently IPM is used to justify agency programs. Despite the hype, little consistency was found in the actual definition of IPM. This project was done to define IPM with more consistency.

The Use of Integrated Weed Management Within a Framework of Ecosystem Management. A proposal for a rational approach to controlling weeds based on ecosystem management. A set of definitions and guidelines is developed for the use of true Integrated Weed Management within a framework of Ecosystem Management.

A Comprehensive List of Vegetation Control Methods. Weed management for the rest of us. This is an outline of specific methods available for the design and implementation of a comprehensive vegetation control program.
