Forty-six (46) BUOWs were observed occupying twenty (20) different burrow locations <br /> located in Suitable Habitat 2,3,and 5. Suitable Habitat 1 and 4 had suitable BUOW habitat; however, <br /> no BUOWs were observed (see Table 1). <br /> Table 1.

BUOW's <br /> are likely to use multiple burrows within their Suitable Habitat range and surrounding habitat is <br /> Suitable Habitat that could likely be occupied. BUOWs are not expected to occur in Colorado between <br /> 11/1 and 3/14 of each calendar year. If operations are expected to occur within 150 feet of the <br /> mapped suitable habitat after 3/14/2019 then 2Dot recommends initiating BUOW surveys again to <br /> assess presence/absence. <br /> If activity is likely to occur prior to 11/1/2018 within 150 feet of mapped suitable habitat and/or <br /> known occupied BUOW burrows, 213ot recommends construction monitoring. 2Dot would monitor <br /> COLORADO WYOMING <br /> 2200 W.29th Ave,Ste 102 www.2dotconsulting.com 116 Bridge Ave <br /> Denver,CO 80211 Saratoga,WY 82331 <br /> Tel.303.953.2255 Tel.307.326.3237 <br /> drones 9 environmental • civil engineering • water I soil I air 9 reclamation • gis <br />
