Abstract

Circium palustre, or Marsh Plume Thistle, has become a plant of major concern in the Robson Valley timber supply area (TSA). It was first reported in the Robson Valley in 1991, and since then has rapidly spread to cover some 83 sites as of the summer of 2002.
This plant can displace native plants and may result in degradation or loss of wildlife habitat if the spread is not controlled.
The purpose of this project is to map the known Marsh Plume Thistle sites and to develop a model of invasion potential in the Robson Valley. The secondary purpose is to make a case for investigating the potential for development of a biological control agent.
