Natural Resources Assessment <br />P125 Gravel Mine - Southwest of State Highway 66 and County Road 17 <br />Weld County, Colorado <br /> <br />ERO Project #24-180 11 <br />ERO Resources Corporation <br />Service’s Information for Planning and Consultation (IPaC) resource list identifies several T&E species in <br />the project area (Table 2). <br />Table 2. IPaC resource list for the project area. <br />Common Name Scientific Name Status* Habitat <br />Habitat Present or <br />Potential to be <br />Affected by <br />Project? <br />Mammals <br />Preble’s meadow jumping <br />mouse <br />Zapus hudsonius preblei T Shrub riparian/wet meadows No habitat <br />Birds <br />Eastern black rail Laterallus jamaicensis T Shallow cattail wetlands and <br />wet sedge meadows with dense <br />cover in the Arkansas River <br />drainage in southeastern <br />Colorado and the Republican <br />River in east-central Colorado <br />Yes <br />Piping plover** Charadrius melodus T Sandy lakeshore beaches and <br />river sandbars <br />No habitat and no <br />depletions <br />anticipated <br />Whooping crane** Grus americana E Mudflats around reservoirs and <br />in agricultural areas <br />No habitat and no <br />depletions <br />anticipated <br />Fish <br />Pallid sturgeon** Scaphirhynchus albus E Large, turbid, free-flowing rivers <br />with a strong current and gravel <br />or sandy substrate <br />No habitat and no <br />depletions <br />anticipated <br />Invertebrates <br />Monarch butterfly Danaus plexippus C Dependent on milkweeds <br />(Asclepiadoideae) as host plants <br />and forage on blooming flowers; <br />a summer resident <br />No habitat <br />Plants <br />Ute ladies’-tresses orchid Spiranthes diluvialis T Moist to wet alluvial meadows, <br />floodplains of perennial <br />streams, and around springs and <br />lakes below 7,800 feet in <br />elevation <br />No habitat <br />Western prairie fringed <br />orchid** <br />Platanthera praeclara T Moist to wet prairies and <br />meadows <br />No habitat and no <br />depletions <br />anticipated <br />*T = Federally Threatened Species, E = Federally Endangered Species, C = Candidate for Federal Listing. <br />**Water depletions in the South Platte River may affect the species and/or critical habitat in downstream reaches in other <br />counties or states. <br />Source: Service 2024. <br />Species Eliminated from Further Consideration <br />The proposed project would not directly affect Preble’s meadow jumping mouse, monarch butterfly, or <br />Ute ladies’-tresses orchid due to the lack of suitable habitat in the project area. The piping plover, <br />whooping crane, pallid sturgeon, and western prairie fringed orchid are species that are affected by <br />depletions to the Platte River system. Based on ERO’s knowledge of the types of activities likely to be <br />implemented as part of the development of the project area, there would be no depletions to the South
