Small mammal surveys on St. Lawrence IslandIn July 2012, the Alaska Center for Conservation Science conducted small mammal surveys on St. Lawrence Island. The team captured 61 individuals from July 20 to July 27 using Sherman and pitfall traps placed near the villages of Gambell and Savoonga in dwarf shrub, graminoid herbaceous, and forb herbaceous habitats. Root voles (Microtus oeconomus), northern red-backed voles (Myodes rutilus) and the St. Lawrence Island shrew (Sorex jacksoni) were captured, and Arctic ground squirrels (Urocitellus parryii) were observed. The report describes survey methods and results, including a description of the habitats in which they were found.

Summary of survey methods
Ten transects were set within a two mile radius of the villages of Gambell and Savoonga. Transects consisted of a series of trapping stations spaced every 5 to 10 meters. Each trapping station had two Sherman traps (baited with peanut butter and rolled oats) and/or unbaited pitfall traps placed within two meters of each other. Individual trapping sessions ranged from 4 to 8 hours and occurred during both day and night. Depending on the species and number of individuals captured, transects were kept open from 4 hours (1 trapping session for pitfall traps) to 2 days (multiple trapping sessions). A total of 61 small mammals were trapped over 4,948 trap hours. All captures were made in Sherman traps.
