Exhibit I & J - Soils & Vegetation Information <br />WEED MANAGEMENT PLAN: <br />Since the list of noxious weed continues to grow; and considering the development <br />of new treatments; this management plan is intended to retain the flexibility needed <br />to meet future conditions and capabilities in the arena of weed management and <br />control. The primary species to be identified, mapped (if found), and treated, are <br />included as an addendum, following: specifically included are Saltcedar and <br />Russian-Olive, as detailed in information from the National Park Service. The <br />addendum material suggests the potential range and methodology of treatment <br />necessary for the control of identified species. <br />Mapping and Identification: <br />Field identification and location of targeted weed species is fundamental to <br />determining the extent and character of weed infestation; and in the subsequent <br />development of a treatment plan. Due to the complex nature of identification, <br />assistance with identification and mapping will be sought from among Weld <br />County Weed and Pest Division; Colorado State University Cooperative Extension <br />Service; U.S. Natural Resources and Conservation Service; as well as on-line and <br />internal resources. <br />Mapping will attempt to identify areas of infestation within the permit boundary, <br />and vectors of infestation from inside or outside the permit boundary. Vectors are <br />a consideration in prevention of future infestation, which may affect on-site <br />behaviors, including method and means of access within permitted lands. An <br />expectation that vectors from adjacent lands must be treated by adjacent <br />landowners if treatment on permitted lands is to be fruitful is part of continuing <br />treatment considerations. <br />Treatment: <br />Once the nature and extent of weeds have been mapped, and vectors identified; a <br />course of treatment options will be considered in order of priority of economy and <br />effectiveness. The overall object of weed management will be to control weeds by <br />establishing a healthy competitive stand of vegetation that wins the competition for <br />plant available water. This effort is linked to on-site soil management; including <br />monitoring of soil fertility and percent organic matter on problem lands; relative to <br />distribution and amount of field available moisture on affected areas. Chemical <br />treatment of weeds will be the last option considered except where all other <br />Varra Companies, Inc. Heintzelman Project RMS 112 Permit Application 7 <br />2 February 2008
