Bemidji – Grand Rapids Biological Assessment and Evaluation drained soils that are occasionally flooded for periods of 2 or 3 months, but it does not reproduce or grow well if flooding is frequent or prolonged (Coladonato 1993b). Species Distribution and Occurrences within the Study Area Slippery Elm ranges from Maine and southern Quebec to North Dakota, south to Florida and Texas. USDA Plants Database at: http://plants.usda.gov/java/county?state_name=Minnesota&statefips= 27&symbol=ULRU Ulmus rubra is only listed by the DRM, so point data from DNR and CNF is not available. Risk Factors The greatest risk to this species is the presence of Dutch Elm disease, which has devastated populations across North America. The proposed project would not affect the spread or presence of this disease. Other threats to this species in sites supporting it are loss of habitat through land conversion and timber harvesting activities such as clearcutting. Studies in southeastern Minnesota showed that slippery elm seedlings grow well in the open or under light shade (USDA 1965). Thus, selective harvesting of surrounding trees may not significantly alter the habitat for this species. It is uncertain how this species would respond to the development of temporary and permanent utility corridor. 4.2.5.12 New England Violet (Viola novae‐angliae) New England violet is listed as DRM Sensitive. Potential effects for this species are described in the following Guilds: Wet Prairie, Wet Meadow and Emergent Wetlands, Riparian Habitats, Lowland Forest, Northern Hardwood Forest, Woodlands and Forest Openings/Exposed Areas/Grasslands. Species Description Viola novae‐angliae is considered a form between Viola sororia and V. sagittata. It is a stemless, hairy or glabrous blue flowered violet that spreads by short rhizomes. Leave are born from base of plant with long hairs, margins with rounded teeth. Flowers are on stalks about as high as the leaves with the two side petals densely bearded with 1mm long hairs. This species is distinguished from the other two above mentioned species by the leaf blades which are distinctly longer than wide but not long and narrow (Gleason and Croquist 2003, Chadde 2002). Species Habitat This species inhabits open, xeric‐mesic rock or sand sites. In Minnesota it occurs most often in rock crevices, along the North Shore of Lake Superior and beside cold, rapidly flowing streams. It also occurs in meadows, grassy lake terraces, and rock outcrops (Coffin and Pfannmuller, 1988). NatureServe (2007) cites this species as being found on undisturbed acidic, xeric, or xeric‐mesic rock or sand substrates, under partially or totally closed‐canopy dry northern forest of mixed hardwoods and conifers.

Bemidji – Grand Rapids Biological Assessment and Evaluation Species Distribution and Occurrences within the Study Area This species is known from the northern tier of US states from Michigan to Maine, and Canadian Provinces Quebec and Ontario. USDA Plants Database at: http://plants.usda.gov/java/county?state_name=Minnesota&statefips= 27&symbol=VINO Viola novae‐angliae is only listed by the DRM, so point data from DNR and CNF is not available. Risk Factors Viola novae‐angliae is a species of open, xeric‐mesic sites, yet there appear to be few threats to its occurrence at a site containing suitable habitat. In fact, destructive activities that would tend to eliminate other rare plant species (disturbed fields, road building, etc.) tend to enhance the species survival. Ballard (1989a cited in NatureServe, 2007) indicated that the species is able to invade such areas at numbers significantly higher than found in natural settings. Such evidence suggests that the habitat is highly recoverable with respect to this species, and that V. novae‐angliae is a species that may be dependent on moderate levels of disturbance. Maintenance of moderately open woodlands via selective logging is probably the most beneficial method for long‐term survival of the species at a given site (Ballard pers. comm. cited in NatureServe, 2007). He suggested that certain human disturbances, if they do not disturb the soil chemistry of the substrate or strongly shade sites, may enhance the vigor and viability of a given violet population (Ballard 1988 cited in NatureServe 2007). The largest populations that have been found have been associated with areas of past, low‐level disturbance: old meadows, disturbed roadsides and power‐line rights‐of‐way. 4.2.5.13 Barrens strawberry (Waldsteinia fragaroides) Barrens strawberry is listed as DNR Special Concern and DRM Sensitive. Potential effects for this species are described in the following Guilds: Northern Hardwood Forest, Woodlands and Forest Openings/Exposed Areas/Grasslands. Species Description Hill (2003) provides the following description for barrens strawberry: Waldsteinia fragarioides ssp. fragarioides is a low perennial herb 10‐20 cm tall with short to elongate slender tough and fibrous (sub‐woody) shallow rhizomes that are generally crowded together and so the colony appears to be in a mat; the roots are mostly adventitious and develop in clusters at rhizome tips; the basal, normally evergreen leaves are also found at the end of the rhizomes, they resemble those of a strawberry, and they have 3 leaflets each at the top of an elongate (3‐17 cm) hairy petiole; the leaflets are broadly cuneate‐obovate, 2‐8 cm long and 2‐6 cm wide, only sparsely hairy, serrate and usually shallowly lobed, the lateral ones are asymmetrical and the middle leaflet is usually longer and wider than the lateral ones; the leaves generally turn somewhat bronze in the winter; stipules are adnate to the petiole or obsolete; the flowers are in a several‐flowered loose cyme on a stalk that about equals the leaves in length. The small flowers are bracteate, yellow, the five petals are obovate to broadly elliptic and generally 5‐10 mm long and 3‐6 mm wide, and they are obtuse or rounded and longer than the five 2‐7.5 mm long sepals. There are numerous stamens July 2010 Species and Associated Habitat Page 4‐80
