Section 2.04.3 Page 6 December 2021 (RN-02)  <br />Grazingland-Subirrigated (GL-SI) occupies large portions of the lowest sites associated with <br />Meehan Draw and Glasier Draw, which crosses the northwest portion of the Glasier Property <br />(outside the permit area). This type corresponds to the U.S. Army Corps of Engineers definition <br />of wetlands in that these areas are dominated by vegetation adapted to growing in saturated soil <br />conditions. This land use type is dominated by native vegetation and occurs primarily as a <br />byproduct of the extensive amount of flood irrigation which occurs in this area. The tail waters <br />from the irrigated fields up slope of this site flow down the depressional bottoms and result in <br />large areas of wetland vegetation which have become established by sub-irrigation and flood <br />irrigation of these low-lying areas. <br /> <br />Grazingland-Reclaimed Spoil (GL-RECS) occurs south and outside of the NHN permit area. <br />This area is distinguished from the previously mentioned Grazingland-Reclamation (GL-REC) <br />land use designation, by the fact that no topsoil was salvaged from this mine area and the area is <br />almost totally dominated by regraded spoil. The vegetation which has become established is <br />primarily a result of voluntary reclamation efforts performed by the previous mine owners and <br />Abandoned Mine Land (AML) Reclamation efforts conducted by the DRMS. Vegetatively this <br />site is largely dominated by shrubs, whereas the Grazingland-Reclamation (GL-REC) consists <br />primarily of a grass dominated vegetation type. <br /> <br /> <br />Pastureland. This land use category is the second largest land use category found in the NHN. <br />There are three different “Pastureland” land use subcategories on this site which include: <br />Irrigated Pasture (PLI), Dryland Pasture (PLD) and Intensively Managed Irrigated Pasture (PL- <br />IMIP). <br /> <br />Irrigated Pasture (PLI) occurs in the areas which have been within the past five years have been <br />irrigated on a regular basis on this site. In this evaluation, areas which were determined to be up <br />slope of the existing irrigation ditches, even although dominated by similar plant species were <br />not considered to be irrigated pasture. Those areas which appear to have been irrigated decades <br />ago that contain ditches, which have not been maintained and which have cement head gates that <br />are now essentially mounts of eroded concrete, and which now largely consist of Prairie Dog <br />colonies, were not considered to be irrigated. The existing extent of irrigated pasture on this tract <br />was closely examined in the fall of the 2008 and throughout the summer of 2009 to identify <br />those areas currently being irrigated as well as those which have within the past five years been <br />irrigated. <br /> <br />Dryland Pasture (PLD) occurs in the areas, which within the past five years have been <br />unirrigated on a regular basis on this site. In this evaluation, areas which were determined to be <br />Dryland Pasture (PLD) were based upon a careful examination of the status of the vegetation <br />growth and the operational condition of the irrigation ditches. Even although dominated by
