Range Extent1000-20,000 square km (about 400-8000 square miles)
Number of Occurrences21 - 300
Rank ReasonsThis species occurs above 3000 m elevation throughout the southern Sierra Nevada Mountains in California, as well as adjacent mountains in Nevada (Belk and Rogers, 2002).
Range Extent CommentsThis species occurs above 3000 m elevation throughout the Sierra Nevada Mountains in California and Nevada, as well as adjacent mountains in Nevada (Belk and Rogers, 2002), and in the southern Cascade Mountains in California (Rogers, unpublished).
Occurrences CommentsThis species is known from California (Inyo, Madera, Mono Cos.), Nevada (Storey Co.) (Belk and Rogers, 2002). Relying on morphology of the base segments, Eriksen and Belk (1999) did not recognize that specimens collected in the Sierra Nevada Mountains from Alpine Co. south to Fresno and Inyo Co. in California were a new species so their discussions of Branchinecta dissimilis from this region actually apply to Branchinecta oriena (Belk and Rogers, 2002).
Threat Impact CommentsAll the known California localities are within wilderness areas and National Forests, and for the most part, are far from areas of continuous, sustained human use (Belk and Rogers, 2002).
Ecology & Habitat
Habitat
This species occurs above 3000 m elevation in temporary pools and shallow marginal areas of permanent lakes that are seasonally inundated; on the drier east side of the Sierra Nevada, southern Casacade and adjacent mountains (Belk and Rogers, 2002).
