| Relation | Central Utah Project; Western Waters Digital Library; adult spotted frogs are present year round construction between mid march and late april would disrupt breeding individuals between mid october and mid march adults typically hibernate in the same areas and would not be able to escape from construction equipment egg masses are present between mid march and mid may tadpoles emerge beginning in early april and may not complete metamorphosis until mid october however the majority of tadpoles appear to complete the transformation by late august the current viability of the wasatch front population is in question because of low population numbers and fragmentation of habitat all temporarily disturbed habitat would be replaced as part of wetland restoration under the SOPs in section 196.1 1961 iggi of chapter 1 other mitigation and conservation measures would be implemented to minimize andor avoid mortality and reduced reproductive success see section 3193.2 31932 31932 the proposed action would have long iong longterm term tenn benefits on spotted frogs by creating and enhancing habitat throughout the provo river corridor about 90.4 904 904 acres of open water emergent marsh and wetmoist wet moist meadow would be created and enhanced by restoring natural functions to the riparian corridor this gain in habitat would offset direct losses thereby resulting in a net increase of 28.1 281 acres of habitat the proposed action would ultimately contribute to the conservation of the species by increasing its distribution and density and securing its habitats 3763.5 37635 37635 impact summary table 332 3 32 summarizes potential impacts of the proposed action on tae species 3764 5764 576.4 376.4 3764 5764 existing channel modification alternative 3764.1 37641 37641 peregrine falcon habitat for peregrine falcon in the impact area of influence consists of areas that attract concentrations of prey including moist meadow wet meadow emergent marsh and open water wetland types this alternative would result in direct short term impacts on peregrine falcons including the temporary removal of 100.9 1009 loog 3 acres of foraging habitat during construction of the project features see table 310 3 10 in section 3464.4 34644 34644 these impacts would last two growing seasons until the area is sufficiently re vegetated as required by wetland SOPs direct and longterm long term losses include 22.9 229 229 acres of habitat in all reaches except reaches 1 and 4 see table 311 3 11 in section 3464.4 34644 34644 these impacts would result from floodplain flood plain grading and placement of fill material in wetmoist wet moist meadow areas for construction of new flood dikes adverse impacts would be minimal because of the infrequent and temporary occurrence of peregrine falcons in heber valley 3764.2 37642 37642 bald eagle longterm long term indirect impacts on bald eagles under the this alternative would include removal of 1080 cottonwood trees and 37.6 376 376 acres of riparian woodland that currently provide suitable osting roosting boosting ro and perching habitat or would potentially develop into such habitat these permanent impacts would be caused by removal of existing dikes in all stream reaches except reaches 1 and 5 about 141.9 1419 acres of riparian woodland would be developed adjacent to the river channel under this alternative development of the riparian woodlands into stands that would provide habitat would take 15 to 30 years these habitat benefits under the existing channel modification alternative would offset the adverse impacts from removal of cottonwood trees and riparian woodland resulting in a net increase of 104.3 1043 acres of habitat temporary and localized disturbance of bald eagles during construction would have minimal impact on bald eagles for reasons described in section 3763.2 37632 37632 the existing channel modification alternative would have longterm long term benefits on bald eagles by increasing fish populations upon completion of the PRRP 3764.3 37643 37643 ute ladies tresses ute ladies tresses would be impacted by the temporary removal of 116.8 1168 acres of marginal habitat during construction of project features see table 314 3 14 in section 3464.4 34644 34644 this habitat is not known to be occupied by ute ladies tresses the losses would be temporary lasting two growing seasons until the areas are restored there is potential for portions of this area to be developed into riparian woodland overstory rather than wetmoist wet moist meadows used as agricultural land this alternative would result in permanent removal of 63.1 631 acres of marginal habitat for ute ladies tresses in particular wetmoist wet moist meadow and riparian woodland habitats 74 |
