From the Ag Journal (Susan Pieper):

Several partners including NRCS (Natural Resources Conservation Service), Colorado Division of Wildlife (CDOW), Colorado Legends and Legacies and Mile High Youth Corps, Colorado State Conservation Board, Colorado State Forest Service, Colorado State University, Colorado Water Conservation Board (CWCB), Fremont County Weed Manager J.R. Phillips and his department, Fremont County Weed Control Department (FCWD); Rocky Mountain Bird Observatory (RMBO), Sangre de Cristo and Southeast Colorado Resource Conservation and Development Councils, U.S. Fish and Wildlife Service Partners for Wildlife Program, Upper Arkansas Cooperative Weed Management Area (UACWM), several conservation districts including Fremont, Turkey Creek, South Pueblo County, El Paso, Central Colorado, Northeast Prowers, Bent County, West Otero Timpas, Custer County-Divide, Upper Huerfano and Spanish Peaks Purgatoire River Conservation Districts plus several individual landowners have undertaken a massive effort to remove tamarisk along the Arkansas River and its tributaries and have provided financial and in-kind support for all the projects being undertaken in the various counties and individual conservation districts.

Also providing the same type of support for the projects are the county commissioners in each of the counties along this stretch of the Arkansas River, Colorado State Land Board, Southeast Colorado Water Conservancy District, Holly Flood District and Tri-State Generation and Transmission.

Generally, water issues can divide communities, but the eradication of this scourge has united producers and governmental agencies across property lines, county lines and even the state line.

Although the Arkansas River banks are the primary target for tamarisk removal, the plan can not be successful within only those boundaries. The Arkansas River, just like any large body of running water, is fed by tributaries and with plants that can produce up to 50,000 seeds annually, controlling the spread of tamarisk on the creeks and arroyos upstream will support the efforts along the river.

In Colorado, approximately 1,414 acres along the Arkansas River in Prowers County have been targeted for eradication with the boards of directors of several conservation districts accepting bids and choosing the applicator to assist them with controlling and eventually ridding the river of this alien species. The same is true for areas up the river where approximately 850 acres were treated, also.

<p.In the lower regions of the Arkansas River, such as in Prowers County and across the state line into Kansas, herbicide application of the plants from the air was chosen.

In Fremont and Custer counties, the targeted areas were tributary streams.
