Important Bird Areas

Middle Provo River UT11

Utah

This area is largely a restoration project funded by the Central Utah Project Completion Act. This includes mitigation efforts for the wetlands lost with the creation of Jordanelle Reservoir. There are approximately 2,050 acres of land within the project, which is officially called the Provo River Restoration Project (PRRP). The area for the project is between the Jordanelle and Deer Creek Reservoirs.

Ornithological Summary

A total of 146 species were recorded from Utah Division of Wildlife Resources standardized counts from 1993 through 2006. The area includes a site surveyed with protocols from the Monitoring Avian Productivity and Survivorship (MAPS) program. These counts were conducted from dawn to 11 am, May through June. The Middle Provo River qualified as an IBA primarily due to use of the area by the Broad-tailed Hummingbird, which is a Utah Partners in Flight Priority Species. Thresholds vary, but preferably a site has 25 or more breeding pairs. From 1997 through 2000 there were extensive surveys of the area. Numbers of breeding pairs for Broad-tailed Hummingbird were 14 in 1997, 39 in 1998, 35 in 1999, and 14 in 2000. There are other Utah Partners in Flight Priority Species that use the area as well. Bobolinks and Cordilleran Flycatchers were found in the riparian area. Virginia?s Warbler, Black-throated Gray Warbler and Brewer?s Sparrow, which are predominately sagebrush/oak and pinyon-juniper upland species, were also found in the riparian area.

Bird species that are on the Utah Division of Wildlife Resources sensitive species list use the area. This includes the Bobolink mentioned above. Pairs of Bobolink using, but not breeding in the area were 23 in 1997, 73 in 1998, 50 in 1999, and 17 in 2000. The area provides foraging habitat for Black Swifts; however, the Black Swift nests below Deer Creek Reservoir in the canyon at waterfall sites. The area can provide migration habitat for Yellow-billed Cuckoo (1 banding record, minimum of 3 sight records). The area also provides migration habitat for Grasshopper Sparrows (multiple sight records) and wintering habitat for Bald Eagles.

The area also qualified due to significant numbers of avian congregations of a single species. Specifically, Yellow Warbler abundances are highest in the state as well as most consistently high in the state.
