Milte Shemtetr (Field Habitat <br />Biologist) and Larry Rogstad (D~vtrict Wildlife Merrager) have reviewed this Rec]amation Permit Application <br />From and made a 5eld visit to the proposed amended trlrtle site in Deccrrlber 1999. The proposed mmmg <br />project will elb'ect a relatively large amount of acreage and we believe there is a very higtl potemial to <br />nrgatively iatpact wildlife atd/or wildlde habitat. We have tnajor concerns tegardmg the wetland ahetation <br />and its effect on both aquatic and terrestrial wildlife. We have had these wrrcerns over the past 11 years as <br />evidenced by the eacbsed letters written by Larry Rogstad to the Weld County Departrrterrt of Planning <br />Services arri Tuttle Applegate Lrrc. The sarrle corcertLS tenleirl today and 1 ask you to please spend the rime <br />read"mg these letters is detail. <br />We believe that Cetl 4 end Cell A contains excellent riparian habitat due to the fact that it is in within the ! 00 <br />year flood plain and u directly associated with the Cache Ia Poudre river bottorn We highly rexomrnend that <br />the warm water slough be albwed to remain m its currert condition Our second preference would be for <br />the existeDCe an intact warm water sough after final reclamation if the west end of the property is to be <br />t[itrled. <br />Of particular cot>cern u the potential for disturbance to the existing and active Great bhre heron (Arden <br />herodias) cobrry boated abng the southwest side of Cell A. These buds are very sensitive to human <br />disturbacees, utcluding huulen uttrusion into colonies, actively used roads, mining activity, road construction <br />and urbani2atiorL Disttubartce rrmy cause aberdonment ofnests and roosts atd may prevent aduhs from <br />adequately Seeding juvetules and themselves (Ehrlich et al. 1988). Buffer zones around breeding cobnies of <br />820 feet (250 m) on land and 492 feet (150 m) in water are t+ecorrmraded (Colorado; Vos et al. ~. DeMalao <br />1993). Additionally, restricting httmen activity, especially early in the breeding season, i9 recommended for <br />those sites at which it h dif5cuh to establish buffer zoces. Buffer zotles should 6e established prior to the <br />breeding season (mid-February) and maintailted unN early August when sites have been deserted for the <br />year. <br />DEPARTI~NT OF NATURAL RESOURCES.
