Uinta Chipmunk Neotamias umbrinus Mammalia — Rodentia — Sciuridae CONSERVATION STATUS / CLASSIFICATION Rangewide: Statewide: ESA: USFS: Region 1: ; Region 4: BLM: IDFG: BASIS FOR INCLUSION Lack of essential information pertaining to status in Idaho; limited population data and threats to habitat. TAXONOMY The subspecies N. umbrinus fremonti and N. umbrinus adsitus occur in Idaho. DISTRIBUTION AND ABUNDANCE This chipmunk occurs in scattered, disjunct parts of the western U.S., from Colorado and Wyoming, west to California. In Idaho, the species occurs in montane areas of the extreme eastern part of the state. POPULATION TREND No data are available to suggest population trend. HABITAT AND ECOLOGY This species is usually associated with montane conifer forests. In Idaho the species has been found in areas with Douglas-fir, Engelmann spruce, and aspen dominating the overstory vegetation and sagebrush and various forbs and grasses comprising the understory (Keller et al. 1986) ISSUES Information is lacking regarding the current status of populations, local distributional patterns, habitat associations, and population trend. Because this species is associated with forested habitat, land uses that affect stand structure and composition could be of importance. RECOMMENDED ACTIONS Surveys are needed throughout the Idaho range of this species to evaluate distribution, population size, and habitat requirements. Information is also needed to indicate population trend.

Cliff Chipmunk Tamias Dorsalis
Wyoming Species Account Cliff Chipmunk Tamias dorsalis REGULATORY STATUS USFWS: No special status USFS R2: No special status USFS R4: No special status Wyoming BLM: No special status State of Wyoming: Nongame Wildlife CONSERVATION RANKS USFWS: No special status WGFD: NSS3 (Bb), Tier II WYNDD: G5, S1 Wyoming Contribution: LOW IUCN: Least Concern STATUS AND RANK COMMENTS Cliff Chipmunk (Tamias dorsalis) has no additional regulatory status or conservation rank considerations beyond those listed above. NATURAL HISTORY Taxonomy: There are six recognized subspecies of Cliff Chipmunk, but only T. d. utahensis is found in Wyoming 1-5. Global chipmunk taxonomy remains disputed, with some arguing for three separate genera (i.e., Neotamias, Tamias, and Eutamias) 6-8, while others support the recognition of a single genus (i.e., Tamias) 9. Cliff Chipmunk was briefly referred to as N. dorsalis 10 but has recently been returned to the currently recognized genus Tamias, along with all other North American chipmunk species 11. Description: Cliff Chipmunk is a medium-large chipmunk that can be easily identified in the field by its mostly smoke gray upperparts, indistinct dorsal stripes (with the exception of one dark stripe along the spine), brown facial stripes, long bushy tail, stocky body, short legs, and white underbelly 2-5. This species exhibits sexual size dimorphism, with females averaging larger than males 2, 3. Adults weigh between 55–90 g with total length ranging from 208–240 mm 4. Tail, hind foot, and ear length range from 81–110 mm, 30–33 mm, and 17–21 mm, respectively 4. Within its Wyoming distribution, Cliff Chipmunk is easy to distinguish from Yellow-pine Chipmunk (T.

Tamias Ruficaudus Simulans, Red-Tailed Chipmunk
Conservation Assessment for the Red-Tailed Chipmunk (Tamias ruficaudus simulans) in Washington Jennifer Gervais May 2015 Oregon Wildlife Institute Disclaimer This Conservation Assessment was prepared to compile the published and unpublished information on the red-tailed chipmunk (Tamias ruficaudus simulans). If you have information that will assist in conserving this species or questions concerning this Conservation Assessment, please contact the interagency Conservation Planning Coordinator for Region 6 Forest Service, BLM OR/WA in Portland, Oregon, via the Interagency Special Status and Sensitive Species Program website at http://www.fs.fed.us/r6/sfpnw/issssp/contactus/ U.S.D.A. Forest Service Region 6 and U.S.D.I. Bureau of Land Management Interagency Special Status and Sensitive Species Program Executive Summary Species: Red-tailed chipmunk (Tamias ruficaudus) Taxonomic Group: Mammal Management Status: The red-tailed chipmunk is considered abundant through most of its range in western North America, but it is highly localized in Alberta, British Columbia, and Washington (Jacques 2000, Fig. 1). The species is made up of two fairly distinct subspecies, T. r. simulans in the western half of its range, including Washington, and T. r. ruficaudus in the east (e.g., Good and Sullivan 2001, Hird and Sullivan 2009). In British Columbia, T. r. simulans is listed as Provincial S3 or of conservation concern and is on the provincial Blue List (BC Conservation Data Centre 2014). The Washington Natural Heritage Program lists the red-tailed chipmunk’s global rank as G2, “critically imperiled globally because of extreme rarity or because of some factor(s) making it especially vulnerable to extinction,” and its state status as S2 although the S2 rank is uncertain.

Life History Account for Uinta Chipmunk
California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group UINTA CHIPMUNK Tamias umbrinus Family: SCIURIDAE Order: RODENTIA Class: MAMMALIA M065 Written by: J. Harris Reviewed by: H. Shellhammer Edited by: R. Duke Updated by: CWHR Program Staff, October 2014 DISTRIBUTION, ABUNDANCE, AND SEASONALITY The Uinta chipmunk occurs at high elevations in the Inyo and White Mts., and in the southern Sierra Nevada from northern Mono Co. to northeastern Tulare Co. Optimal habitat is open, subalpine conifer forest of whitebark, foxtail, limber, and bristlecone pines. Prefers exposed slopes and ridges near timberline. In the White Mts., occurs from 2560- 3450 m (8200-11,000 ft) (Hock 1963), and in the Sierra Nevada, from 2350-3280 m (7500-10,500 ft) (Johnson 1943). SPECIFIC HABITAT REQUIREMENTS Feeding: Feeds mainly on seeds and fruits, including pines, juniper, grasses, and forbs, as well as on fungi. Searches on the ground, in shrubs, trees, and snags. Stores food in underground caches. Cover: Uses scattered subalpine trees as refuges (Johnson 1943). Also uses brush and rocks for shelter. Reproduction: Uses burrows, snags, and logs for nesting. Water: Probably does not require water source other than food, but may use such sources if available. Pattern: Associated with sparse to open-canopy subalpine conifer habitats. SPECIES LIFE HISTORY Activity Patterns: Diurnal. Probably hibernates (Heller and Poulson 1970), with periods of dormancy lasting several days separated by arousals for feeding. Seasonal Movements/Migration: None. Home Range: In Nevada, home ranges measured 100 m (325 ft) in the longest dimension (Brown 1971). Territory: May defend nest area and concentrated food sources.

2005 WAP Information K-1
APPENDIX K 2005 WILDLIFE ACTION PLAN INFORMATION 2005 WAP Development and Review Process Public Involvement and Partnerships A series of public scoping meetings were held throughout the state in February, 2003. Presentations were made in Reno, Las Vegas, and Elko to introduce Nevadans to the concept and opportunity of the WAP. Over 100 invitations were sent out to agencies, NGOs, and, hunting, fishing, and environmental groups. Attendance to these initial presentations was very light, but the themes that emerged from the discussions were very useful in guiding the WAP development strategy. Attendees were supportive of an inclusive, collaborative approach to developing the Strategy, they advocated the integration of existing and ongoing planning efforts into the WAP, and they advocated the sharing and consolidation of data into comprehensive databases. The next step in collaborative planning for the WAP was taken in August, 2003 when NDOW commissioned a working group of active individuals from the conservation community to work on alternative funding for the Wildlife Diversity program. This working group met several times in the next two years and provided input and guidance into the process. WAP Development Team members attended a Rural Planning Conference on January 20, 2005, to introduce the Strategy to county planners and solicit their attendance and participation in the upcoming round of open houses across the state. Following the development of a series of draft analytical products, the WAP Development Team took the draft analysis on the road for a seven-city tour of Nevada to receive a second round of input. The meetings were held in open-house format in Reno, Carson City, Las Vegas, Tonopah, Ely, Elko, and Winnemucca between March 16 and 31, 2005.

NATURAL HISTORY Taxonomy: Chipmunk taxonomy remains disputed, with some arguing for three separate genera (i.e., Neotamias, Tamias, and Eutamias) 1-3, while others support the recognition of a single genus (i.e., Tamias) 4. Uinta Chipmunk (briefly N. umbrinus) 5 has since been returned to the currently recognized genus Tamias, along with all other North American chipmunk species 6. Of the seven recognized subspecies of Uinta Chipmunk, three are found in Wyoming: T. u. fremonti, T. u. montanus, and T. u. umbrinus 7-10. These subspecies are geographically isolated on different mountain ranges and are not believed to interbreed 10. Description: Identification of Uinta Chipmunk is possible in the field. Uinta Chipmunk is a medium-sized, brownish chipmunk with dark facial stripes, three dark and four light longitudinal dorsal stripes, white underbelly, long bushy tail, and a large head that is longer than 34 mm 8, 10. Males and females are similar in size and appearance 10. Adults weigh between 55–80 g and can reach total lengths of 200–243 mm 10.
