Inflectarius magazinensis (Pilsbry and Ferriss, 1907), the Magazine Mountain Shagreen, is an endemic land snail found only on Magazine Mountain, Arkansas, U.S.A. This species was given the status of threatened in 1989, but was removed from the threatened list by the United States Fish and Wildlife Service in June 2013 due to apparent stability of the population within its known habitat. Inflectarius magazinensis is a rupicolous species inhabiting talus areas of Savanna sandstone. Populations occur from approximately 670 m to 790 m on the north and west sides of Magazine Mountain. Our study was designed to gather information regarding basic natural history and ecology knowledge for this species. We examined both known localities and sites where there were no historical records for the presence of I. magazinensis but suitable habitat was present. We found that this species is restricted to only the north- and west-facing slopes of Magazine Mountain. Due to its restricted habitat preferences, the total range of this species amounts to approximately nine hectares on the upper slopes of the mountain. Because I. magazinensis is endemic to Magazine Mountain and restricted to upper elevations, it should be monitored on a regular basis. Due to levels of uncertainty in terms of climate change, pollution, and disturbance (both natural and anthropogenic), habitat health should be taken into consideration as a metric used for monitoring the stability and long-term viability of this species.
