Bemidji – Grand Rapids Biological Assessment and Evaluation Species Distribution and Occurrences within the Project Area The red‐backed salamander is widely distributed across the northeastern United States, generally within the Great Lakes States and New England, Virginia and North Carolina, as well as in southern Ontario and Quebec (USGS, 2008; NatureServ, 2009). Within Minnesota, the red‐backed salamander is restricted to the northeast portion of the state and is on the western periphery of its range (DNR, 2009c). Within the Study Area, observations of red‐backed salamanders have not been documented; however appropriate habitat is likely present. According to the National Amphibian Atlas, this species is present in Cass and Itasca Counties (USGS, 2008). Risk Factors While relatively tolerant of human disturbance in forests, this species can be sensitive to the removal of key habitat factors such as leaf litter, fallen logs or disturbance of underground sanctuaries. This species would also be sensitive to the conversion of forest cover to open habitats (Harding, 1997). 4.2.4.3 Green Frog (Rana clamitans) The green frog is listed as DRM Sensitive. Species Description Green frogs are known to occur in a range of colors varying from green, yellowish green, olive, grey and in rare cases, even blue. Black spotting on the back and legs is common. A ridge of skin runs from each eye and extends approximately two‐thirds down the back. The belly is white, sometimes with grey speckles. Mature males have bright yellow throats while the female’s throat is light yellow or cream colored. Each sex has a large tympanum, which is typically of equal or greater size than the eye. Breeding takes place in spring and summer when males can be heard calling their distinctive “clung” (or loose banjo string sound). Species Habitat Green frogs inhibit a wide range of aquatic environments including lakes, sloughs, swamps, slow moving streams and impoundments, although they seem to prefer habitat with permanent standing water. This species typically prefers riparian habitats but may disperse beyond these areas during warm, rainy evenings. Winters are spent in dormancy, buried in bottom mud or debris, between early November and early April (Harding, 1997). Species Distribution and Occurrences within the Project Area The green frog is widely distributed across the eastern United States. It range stretches between northwest Minnesota, eastern Texas, northern Florida, New England, New Brunswick, Quebec and Ontario (Harding, 1997). In Minnesota, this species is on the northwest fringe of its range, where it occurs across the eastern half of the state (DNR, 2009c). Within the study area, observations of green frog have not been documented; appropriate habitat is present. According to the National Amphibian Atlas, this species is present in Cass, Itasca, and Hubbard counties (USGS, 2008). Risk Factors Risk factors include loss of appropriate wetland habitat due to drainage or filling (NatureServ 2009). July 2010 Species and Associated Habitat Page 4‐41
Bemidji – Grand Rapids Biological Assessment and Evaluation 4.2.5 Plant Species For effects analysis on plant species, each of the following species have been ascribed to a broadly defined guild based on shared habitat requirements. Some species occur in multiple guilds based on their ability to inhabit a wider range of habitat types. While there are many risk factors identified for the various plants being evaluated, only a few of those factors are directly applicable to this Project. Consideration of risk factors such as climate change, drought and/or flooding are not directly applicable to the Project and are beyond the scope of this evaluation. The primary risk factors related to the project include habitat loss, local changes to light and moisture regimes, introduction of NNIS and direct destruction due to construction activities, 4.2.5.1 Dragon’s Mouth Orchid (Arethusa bulbosa) The dragon’s mouth orchid is listed as DRM Sensitive because it is rare and may experience habitat loss due to beaver flooding and development. Potential effects for this species are described in the following Guilds: Bogs and Fens, Sedge Meadows and Emergent Wetlands, Cedar and Mixed Conifer Swamps. Species Description The dragon’s mouth orchid has stems between 7 and 36 cm long, glabrous from a bulbous corm. It has one linear lanceolate leaf that only protrudes upward following flowering. Inflorescence is comprised of a single brilliant rose‐purple flower distinguished from other similar species by the absence of the leaf during flowering. Species Habitat This species is found in various types of coniferous swamps, but most commonly on a substrate of deep Sphagnum moss under partial canopy gaps. It may also be present on floating mats around “bog” lakes in acidic, peaty sedge meadows (Smith, 1993). Minnesota populations are known from conifer swamps, floating mats, fens, and sedge‐dominated water tracks. It is usually associated with wet, sunny, or partially shaded conditions and hummocks of Sphagnum moss (Coffin and Pfannmuller 1988). Species Distribution and Occurrences within the Study Area Dragon’s mouth orchid extends across temperate and boreal North America along a band from Saskatchewan, south from the Great Lakes states to Virginia and North Carolina, and north to Newfoundland and Labrador. <strong>USDA</strong> Plants Database at: http://plants.usda.gov/java/county?state_name=Minnesota&statefips= 27&symbol=ARBU NHIS data indicates six population records of this species distributed across the overall project boundary. These records are located throughout the Study Area in bogs and conifer swamps. CNF does not track this species. Risk Factors Risk factors to Dragon’s mouth orchid include alteration of existing hydrology, shift from a partially closed canopy to an open setting due to forest removal, and direct impact to individuals due to construction.
