A survey of the reptiles and amphibians of the central and eastern portions of Pictured Rocks National Lakeshore, MI was conducted to provide information concerning the effect that the proposed Beaver Basin Rim Road would have on their populations. The study area was divided into 6 zones. Eight habitats were identified: northern hardwoods, mixed deciduous/coniferous, mixed coniferous, white cedar/tag alder, sphagnum bog, lakes and ponds, stream, and coniferous plains. Sampling of snakes, frogs, toads, newts, salamanders, and turtles was conducted during daytime and nighttime hours from April through August (192 hrs over 24 days). The reptiles and amphibians were collected by hand, dip net, baited minnow traps, and modified fyke nets (turtle traps). Vocalizations of frogs and toads were also used to identify and count those species. Sampling time was not equal among the zones. Abundance of each species is given for each zone, each habitat type, and in total. Nineteen of the 26 species of reptiles and amphibians known from the Upper Peninsula were collected. This included 4 salamanders, 1 newt, 4 snakes, 3 turtles, 6 frogs, and 1 toad.
