ESA status: under review (November 2022)

The Shasta sideband and Wintu sideband are terrestrial snails inhabiting the vicinity of Shasta Lake, in Shasta  County, California.  

The Wintu sideband occurs at eight sites, most of which are along the Pit River arm of the lake (Burke et al. 1999, Sect. 11, p. 5; USDA and USDI 2007, p. 93).

Seven of those eight sites are on Federal land (USDA and USDI 2007, p. 93). Both subspecies are apparently restricted to limestone outcrops or related substrates,

and are associated with caves, talus, or rocky outcrops in open, brushy, and late-successional pine-oak woodland  areas.

Shasta and Wintu sidebands are threatened by habitat loss due to logging, road construction and maintenance, and recreation.
