agricultural habitats (Holmes, 1994). Leaving a portion of Prairie Dog Colony A intact would meet the <br />buffer recommendation as well as maintaining an important food source for the raptors. <br />®Species associated-with prairie dog colonies the Black-footed Ferret an&the Burrowing~wl may <br />potentially occupy the site. The permit application does not state whether a survey for Black-footed <br />Burrowing Owls are absent from this area during the winter, we recommend that a survey for the <br />presence of the owls is conducted prior to disturbance of prairie dog colonies from Mazch 1-October 31. <br />The Wildlife Resources Assessment states that a survey for Preble's Meadow pmg Mouse has been <br />conducted and a report sent to US Fish and Wildlife Service for their approvae assessment also <br />states that potential Mountain Plover habitat exists in the southern portion of the project area, but does <br />not state if a survey has been done for the plover's presence. <br />The Mining Plan specifies a 200' setback from the South Platte River. The maps, however, appeaz to <br />have a setback only where the jurisdictional wetlands are indicated. In order to protect the riparian area <br />and the diversity of large and small mammals, birds, and hetptiles that inhabit the site, a 200' setback <br />from the western shoreline of the river is recommended. It is also recommended to keep as many of the <br />mature cottonwoods as possible, and to leave snags where feasible. It is our understanding that <br />disturbance of wetlands on the western part of the site will be mitigated by about 100 acres of wetlands <br />created during the reclamation phase. <br />The Reclamation Plan states that the disturbed area will be planted with a native grass seed mixture, <br />shrubs, and trees recommended by the MRCS. It is recommended that an ongairrg weed management <br />plan be implemented in order to enhance the quality of the habitat for witdiife. The ponds created during <br />po o ave a s ore me s ope o a ut :. ope of 5: and an irregular shoreline <br />would encourage more emergent vegetation and use by ducks and other waterfowl. Addition of <br />underwater topography would enhance the ponds as fisheries. <br />Thank you for the opportunity to comment on this project.
