| Relation | Central Utah Project; Western Waters Digital Library; special status species wanrhodes Wa nrhodes and little diamond creeks and determined that the diamond fork drainage currently has no pure strains the abundance and quality of the stream and lake habitat once available to the subspecies has declined as a result of water diversion and degradation of riparian habitats from grazing road building mining and timber harvest perhaps the greatest effect I is from the introduction ofother of other salmonids salraonids salmon saimon ids rail rall rali rainbow lbow abow trout havethyl hav have 11 ethyl hybridizer hybridized umidized umidi zed with cutthroat throughout the west and competition and predation from brook and brown trout are suspected to have significantly reduced cutthroat numbers kershner 1995 hybridization with other subspecies of cutthroat trout has also reduced pure strains of bonneville cutthroat 3752.2 37522 37522 birds the following birds are of special concern golden eagle surveys for nesting raptors raptores in the diamond fork drainage area have been conducted annually since 1990 keller 1997 the surveys consisted of observing historical nest sites and potential cliff habitat for any activity within or adjacent to the site or for the presence of stick nests that would indicate active use six pairs of golden eagles are known to nest within diamond fork canyon three pairs are located within vi 12mile mile mlle of the construction area for the proposed diamond fork siphon red mountain tunnel and red hollow pipeline one of the three pairs has two nests near the proposed red mountain tunnel outlet portal the second pair has seven to eight nests in the vicinity of monks hollow the third pair has recently been discovered keller 1999a nesting near the proposed diamond fork siphon location the three other pairs known to nest in diamond fork canyon are approximately equally spaced from the canyons confluence with spanish fork river to the three forks area about 15 miles upstream one of these nests would be within vz 12 mile of three forks dam a no action alternative feature the golden eagle is not a listed species or a candidate species for listing under ESA however it is protected under the eagle protection act primarily because of its looks similar to bald eagles and under the migratory bird treaty act littell 1992 golden eagles are holarctic in distribution clements 1978 and are found in virtually all habitats of the western united states palmer 1988 with few exceptions their breeding range is unchanged from historical times harlow and bloom 1987 olendorff et al 1981 estimated a wintering population of ofnearly nearly neaily neally 50000 in the western states and braun et al 1975 estimated a total population of 100000 for all of north america during at least one recent year the golden eagle population in utah was reported to be increasing although this may have been temporary due to local increases in prey harlow and bloom 1987 the species is relatively common throughout utah and juab counties shields and moretti 1982 surveys for nesting raptors raptores in the diamond fork drainage area have been conducted annually since 1990 keller 1997 the surveys consisted of observing historical nest sites and potential cliff habitat for any activity within or adjacent to the site or for the presence of stick nests that would indicate active use loggerhead shrike in central utah loggerhead shrike are considered year round residents and are found in suitable habitat throughout the effect area of influence shields and moretti 1982 smith and greenwood 1983b while migrant shrike populations elsewhere in the united states continue to be designated as category 2 candidate species the utah population is no longer a candidate species for listing under ESA FWS 1994c the breeding and wintering range of these birds extends from southern canada to southern mexico clements 1978 they occupy open country such as the sagebrush and pinyon juniper habitats in utah shields and moretti 1982 noted shaikes shrikes in five habitats near utah lake deciduous woodland tamarisk shadescale sha descale

agricultural fields primarily but not exclusively in the northern valleys and west deserts of utah while swainsons swainsona Swain sons hawk populations in utah have declined from historical levels they have increased in utah and across its range from 1966 to 1994 however pesticide poisonings poison ings of tens of thousands of swainsons swainsoifs swainsona Swain sons hawks have occurred since
