Problems <br />Salt Cedar and Russian olive disrupt the structure and stability of native plant communities and degrades <br />native habitat by out competing and replacing native plant species, monopolizing limited sources of <br />moisture, and increasing the fiequency, intensity and effect of fires and floods. Chace established, they are <br />difficult to control and nearly impossible to eradicate. Management of these species requires a long-term <br />commitment and usually involves a combination of control methods such as mechanical and chemical for <br />success. With these growth characteristics in mind, the following guideline was developed to assist <br />operators in controlling Salt Cedar and Russian olive on permitted mine lands. <br />Operators are encouraged to consult with their local weed management authority (district) when <br />developing any weed management plan. <br />Control Methods During Mining <br />Keep disturbance footprint as small as possible <br />Disturb only the acreage to be mined in the upcoming field season <br />• Minimize number of roads and equipment storage areas <br />• Reclaim affected areas as soon as possible <br />• Implement control methods prior to disturbing new areas <br />Minimize or eliminate wetted soils and puddling, create positive drainage at all times, and where <br />practicable: <br />• Slope all affected areas to prevent puddling and facilitate rapid drying of surface soils <br />• Convey water via pipes or other means to prevent wetted soils; limit ditch conveyance <br />• Conduct operations that expose moist soils at a time when tamarisk are not producing seed or have <br />not in the past 45 days (September - mid April, see later comments about seed longevity and wet <br />soils) <br />Control/Management <br />• Mechanical <br />- Root plowing <br />- Bulldozing (over many years) <br />- Fire (over many years) <br />- Inundation (long tern) <br />• Chemical <br />- Foliar spaying
