Weed Management Plan

Before releasing any biological control agents onto Forest System Lands, RER will approve
the release with the BHNF-BRD.
Chemical
Herbicides have been found to be very effective in controlling weeds. Selected herbicides will
be EPA approved and appropriate for the target species. Herbicides used must be labeled for
rangeland/forested lands and should be target specific.
All herbicides selected for use will be approved by the BHNF-BRD, as some brands are
preferred for use over others depending on target species.
Spot spraying is the preferred method of application using handheld equipment. Vehicles, all-
terrain-vehicle (ATV’s) backpack sprayers, wickets, and other equipment developed for spot
treatment are also application methods. Using spray booms for application will be determined
on a site by site basis as appropriate.
The applicator will obtain a General Permit for Minor Pesticide Discharges (WYG260000)
prior to pesticide application and applicator(s) will carry a copy while conducting herbicide
applications.
Herbicides will only be applied by a commercially licensed pesticide applicator; a copy of the
applicator’s license must be submitted to RER and the BHNF-BRD.
Buffers will be used around water sources, lakes, wetlands and riparian areas, and streams to
keep concentrations of chemical herbicides in water well below those harmful to drinking,
irrigation, aquatic life, and non-target vegetation. Treatment of individual plants with aquatic-
labeled chemical agents may occur within buffer areas.
Adjuvants approved by the BHNF-BRD may be added to the herbicide tank mix to improve
the effectiveness of the herbicide, promote better contact with the plant surface, and reduce
drift.
Herbicide use will be monitored on an annual basis. At the end of each treatment season,
pesticide use reports will be completed to document types and amounts of herbicides used and
submitted to RER and the BHNF-BRD.
Daily logs of herbicide use will also be kept to document the herbicides used, pounds of active
ingredient applied per acre, gallons used, method of application, target species, and locations
of application.

Target Species Management
The following species descriptions are from the WyomingWeed and Pest Council Weed Handbook.
Integrated management techniques are derived from a variety of sources: Batcher, S. et al. (2002),
Beck, K.G. (2008), Dewey, S. (2006), Fremont County Weed and Pest (2012), Jacobs, J. (2008),
Kadramas, T. (2002), Kedzie-Webb, S. et al. (2009), Lincoln County Noxious Weed Control Board
(2012), Moser, L. et al., Schwarclander et al. (2011), Sheley, R. et al., The Nature Conservancy
(2011), USDA NRCS (2011), USDI NPS (2010), Wilson and Randall (2005), Winston and
Schwartzlander (2011a), and Winston and Schwartzlander (2011b). Integrated management
chemical control agents are based on the 2006-2007 Weed Management Handbook from
Cooperative Extension Services (Dewey et al. 2006).
