Biological Assessment and Evaluation<br />

Route 2 Alternative (US 2)<br />

This alternative crosses numerous broad riparian corridors including the Necktie River, The Pike Bay<br />

channel, Sucker Creek, Portage Creek Six Mile Brook, Mississippi River, and Ball Club River.<br />

For those species adapted to open settings, project activities are likely to only have an impact in areas of<br />

direct power pole installation.<br />

• Six Botrychium minangense populations were observed in 6 locations during Enbridge and HDR<br />

surveys in this route. DNR data shows three populations of this species in Cass Lake along the<br />

Enbridge corridor. CNF indicates one population near a DNR point in Cass Lake.<br />

• Botrychium pallidum was observed in three new locations in HDR 2009 surveys along the north<br />

side of the tree strip located between the Enbridge corridor and the BNSF railroad. DNR records<br />

show eight records for this species along the Enbridge corridor. CNF point data indicates 12<br />

populations of this species along the Enbridge corridor.<br />

• Enbridge corridor surveys in 2008 identified a cluster of Carpinus caroliniana south of the<br />

corridor near the intersection of Highway 10 and US 2. Neither the DNR nor the CNF track this<br />

species.<br />

• White pine is present in all age classes in a mix of forests along this route.<br />

• More than 65 individual Viola novae‐angliae plants were identified in two locations. One of<br />

these populations is present on private lands south of Zemple in the floodplain of Deer River.<br />

Woody and herbaceous species would be cleared within the work space of the project during<br />

construction and periodic maintenance will prevent future canopy closure. These activities will directly<br />

affect some of the known occurrences for species adapted to shaded conditions as areas will be exposed<br />

to additional direct sunlight. Species adapted to partial or full shade include Botrychium minganense and<br />

Carpinus caroliniana. Where clearing of canopy occurs, sun intolerant species of this guild are likely to<br />

be adversely effected, directly and indirectly. Prior to construction, field surveys will be conducted to<br />

identify individual occurrences of species in this guild and route shifts will take place if possible. Where<br />

impacts are unavoidable, the applicant will obtain necessary take permits and negotiate appropriate<br />

mitigation.<br />

Route 3 Alternative (Northern Route)<br />

This alternative crosses numerous broad riparian corridors including the Necktie River, The Pike Bay<br />

channel, Sucker Creek, Portage Creek Six Mile Brook, Mississippi River, and Ball Club River.<br />

• Botrychium pallidum was observed in four locations with at least 23 individuals identified within<br />

Route 3 in 2009. All observations were in or adjacent to lowland forests.<br />

• White pine is present in all age classes in a mix of forests along this route.<br />

• Sixty‐three individual Viola novae‐angliae were observed along one quarter mile segment within<br />

the right of way of Highway 6 on state forest land<br />

Woody and herbaceous species would be cleared within the work space of the project during<br />

construction and periodic maintenance will prevent future canopy closure. These activities will directly<br />

affect some of the known occurrences for species adapted to shaded conditions as areas will be exposed<br />

to additional direct sunlight. Species adapted to partial or full shade include Botrychium minganense and<br />

B. pallidum, though B. pallidum is also found in open habitats. Where clearing of canopy occurs, sunintolerant<br />

species of this guild are likely to be adversely effected, directly and indirectly. Prior to<br />
