Exhibit 2 1 CPW Recommendations Sand and Gravel Mining Lease 112629; Huerfano County I July 10- 11,2019 Page 5 of 9 Page 12 of 19 tolerate human habitation to within 200 yards of their nest. Development that encroaches on rural sites is likely to cause abandonment. SWAINSON'S HAWK Nest Site: No surface occupancy (beyond that which historically occurred in the area)within '/4 mile radius of active nests. Seasonal restriction to human encroachment within 'A mile radius of active nests from April 1 through July 15. Some members of this species have adapted to urbanization and may tolerate human habitation to within 100 yards of their nest. PEREGRINE FALCON Nest Site: No surface occupancy (beyond that which historically occurred in the area)within '/2 mile radius of active nests. Seasonal restriction to human encroachment within '/2 mile of the nest cliff(s) from March 15 to July 31. Due to propensity to relocate nest sites, sometimes up to '/2 mile along cliff faces, it is more appropriate to designate 'Nesting Areas' that encompass the cliff system and a '/2 mile buffer around the cliff complex. PRAIRIE FALCON Nest Site: No surface occupancy (beyond that which historically occurred in the area)within '/2 mile radius of active nests. Seasonal restriction to human encroachment within '/2 mile radius of active nests from March 15 through July 15. NORTHERN GOSHAWK No surface occupancy (beyond that which historically occurred in the area)within '/2 mile radius of active nests. Seasonal restriction to human encroachment within '/2 mile radius of active nests from March 1 through September 15. BURROWING OWL Nest Site: No human encroachment within 150 feet of the nest site from March 15 through October 31. Although Burrowing Owls may not be actively nesting during this entire period, they may be present at burrows up to a month before egg laying and several months after young have fledged. Therefore it is recommended that efforts to eradicate prairie dogs or destroy abandoned towns not occur between March 15 and October 31 when owls may be present. Because nesting Burrowing Owls may not be easily visible, it is recommended that targeted surveys be implemented to determine if burrows are occupied. More detailed recommendations are available in a document entitled "Recommended Survey Protocol and Actions to Protect Nesting Burrowing Owls"which is available from the Colorado Division of Wildlife July 2019 Board Packet I Page 180 of 412
