Survey for listed invertebrate species along the Proposed Beaver Rim Road in the Pictured Rocks National Lakeshore
Pearce T, Nielsen M, Rogers E. 1992. Survey for listed invertebrate species along the Proposed Beaver Rim Road in the Pictured Rocks National Lakeshore. White Water Associates, Inc. Amasa, MI
Terrestrial invertebrates were collected along the corridor of the proposed Beaver Basin Rim Road in Pictured Rocks National Lakeshore, MI to assess the impact that the road might have on the habitats of threatened, endangered, and special concern species of gastropods and insects. Sampling took place over 3 days in late July when the weather was dry and on 2 days in late September during rainy weather. Live and dead gastropod shells were collected from 34 sites in 5 habitat types (northern hardwoods, mixed deciduous/coniferous forest, cedar swamp, pine-dominated or grassy plains, and marshes). The insect survey was conducted by car and foot and was timed to coincide with the flight season of the threatened northern blue butterfly. Ultraviolet light attractant was used 1 night in July in an open pine barren. Two special concern gastropods were collected but no listed insects were found. A taxonomic list is presented of the gastropods collected. No list is provided of the insects collected. A map indicating the location of sampling sites in the corridor of the proposed road is included. Information is also included about each endangered, threatened, and special concern insect species that might be present in Pictured Rocks National Lakeshore. In addition to results of a search for listed invertebrates, the authors include a list of land snail (mollusc) species found.
