Weed Control
Project Partnership for Regional Invasive Species Management ( P.R.I.S.M. )
Project Description
The National Bison Range Complex (NBRC) is located in central western Montana amongst a checkerboard of private, federal, tribal, state and local land ownership. Invasive species management had been an ongoing battle for managers of these lands and continues to be a primary threat to the resources we strive to protect and manage. Cooperators agree that effort to locate and eradictated new invaders, such as rush skeletonweed, flowering rush, blueweed, dame's rocket, orange and meadow hawkweeds, are high priority. We also recognized that established infestations of prolific and widespread non-native species, such as dalmation toadflax, houndstongue, whitetop, spotted knapweed and Canada thistle, have become an economic drain and a landscape level dilemma. In an attempt to increase our return per cost expenditure the Partnership for Regional Invasive Species Management (PRISM) in Western Montana was started.

Purpose and Objectives
 The purpose of the agreement is to initiate a landscape level partnership between local land managers that foster cooperation between agencies, non-governmental organizations and private landowners a like, in an attempt to ,ore effectively control invasive species in our region. Coordination efforts in managing established species as well as combining forces in locating and eradicating new invaders are priority goals for this project. This partnership will focus on: identifying priority species and priority areas, mappign existing and searching for new infestations, using integrated control methods and synthesizing and sharing information on both new and existing infestations.

Goals of the Partnership
•  Design invasive species management plans from the infestation and watershed level
•  Act as a central reporting group for information regarding new invaders from which searches, mapping, and management plans can originate
•  Investigate reports and known areas of new invaders
•  Produce an inventory list and merge existing maps of invasive speciesin the region
•  Identify priority areas where cooperators can focus efforts on established infestations
•  Classify species by priority and provide recommendations for integrated management
•  Facilitate a collaborated treatment effort between cooperators
•  Produce and distribute educational materials regarding the identificaton, spread, prevention,and treatment of invasive species
•  Plan community events that involve and educate the public
