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 />
