The Bureau of Land Management has worked cooperatively with State Agencies and political subdivisions thereof, to manage invasive plants on Federal and adjacent public and private lands. Federal lands are widely scattered and are often difficult to access. Counties, cities, towns, villages, and special districts have often developed positive relationships with adjacent landowners and have a successful history of cooperatively managing weeds on a landscape scale across multiple jurisdictions. The objectives of this partnership are to treat and monitor weeds cooperatively across multiple jurisdictions within Umatilla County. This cooperative agreement shall prioritize and target undesirable plant species or group of species to be controlled or contained within a specific geographic area; establish a timeframe for the initiation and completion of the tasks specified in an integrated management system; describe the integrated management system to be used to control or contain the targeted undesirable plant species or group of species. An integrated management system means a system for the planning and implementation of a program, using an interdisciplinary approach, to select a method for containing or controlling an undesirable plant species or group of species using all available methods, includingďż˝ education; preventive measures; physical or mechanical methods; biological agents; herbicide methods; cultural methods; including targeted grazing; and replanting as necessary.
