Bemidji – Grand Rapids Biological Assessment and Evaluation Impacts to individuals and appropriate habitat areas will be minimized by spanning wetland areas when possible and by applying BMPs to construction in wetlands. If an active nest is found during construction, potential impacts and avoidance will be assessed and coordinated with the appropriate agencies. No Build Alternative The no build alternative would maintain the existing conditions along each alternative. No habitat impact would occur. Determination of Effects Route 1 Alternative (Great Lakes Pipeline) • CNF: Not listed. • DNR: Not listed. • DRM: May adversely impact individuals, but not likely to result in a loss of viability in the Planning Area, nor cause a trend toward Federal listing. Minimal area of appropriate habitat area would be reduced as a result of structure placement in wetlands, and increased through clearing of woody vegetation within the right‐of‐way. Route 2 Alternative (US 2) • CNF: Not listed. • DNR: Not listed. • DRM: May adversely impact individuals, but not likely to result in a loss of viability in the Planning Area, nor cause a trend toward Federal listing. Minimal area of appropriate habitat area would be reduced as a result of structure placement in wetlands, and increased through clearing of woody vegetation within the right‐of‐way. Route 3 Alternative (Northern Route) • CNF: Not listed. • DNR: Not listed. • DRM: May adversely impact individuals, but not likely to result in a loss of viability in the Planning Area, nor cause a trend toward Federal listing. Minimal area of appropriate habitat area would be reduced as a result of structure placement in wetlands, and increased through clearing of woody vegetation within the right‐of‐way. 5.2.1.5 American Bittern (Botaurus lentiginosus) American bitterns are known to occur in the Study Area in emergent wetlands with a standing water component. Direct & Indirect Effects Current transmission line construction practices minimize impacts to wetland habitats by spanning these areas (when possible), constructing these segments during the winter months (when appropriate), using mats to minimize impacts from heavy equipment (when appropriate), allowing native vegetation to recolonize disturbed areas and by maintaining existing hydrology and grade. Permanent loss of wetland habitat will be restricted to the footprint of transmission line structures placed in wetland areas. Forested wetlands would be converted into emergent or scrub/shrub wetlands, as trees would be July 2010 Environmental Consequences Page 5‐19
Bemidji – Grand Rapids Biological Assessment and Evaluation removed to allow for transmission line development. Temporary impacts to wetland habitats may occur as a result of construction activities. If structures are placed in large emergent wetlands which are lacking standing snags or scattered trees, they may provide a perching opportunity for hunting raptors. American bitterns have been known to fall prey to great‐horned owls (EPA, 2009), so individuals found along the chosen route may experience increased pressure. Human activity along the chosen route will be high during construction when compared to nearby areas of unfragmented habitat. This may prevent American bitterns from using suitable habitat along the ROW, especially if individuals have a low tolerance for humans. Route 1 Alternative (Great Lakes Pipeline) No DNR observations of this species have been made within one mile of Route 1. During the EP surveys, no additional observations were made. The CNF does not track this species. Appropriate habitat likely exists where this route crosses emergent wetlands interspersed with standing water. Several large wetland complexes are crossed by Route 1 which are likely of sufficient of area to support breeding. Minimal impacts to appropriate wetland habitats would occur as a result of structure placement. Right‐of‐way clearing would increase the area of meadow and emergent habitat available for this species Impacts to individuals and appropriate habitat areas will be minimized by spanning wetland areas when possible and by applying BMPs to construction in wetlands. If an active nest is found during construction, potential impacts and avoidance will be assessed and coordinated with the appropriate agencies. Route 2 Alternative (US 2) No DNR observations of an American bittern have been made within one mile of Route 2. During the EP survey period, no additional observations were made. The CNF does not track this species. Appropriate habitat likely exists where this route crosses emergent wetlands interspersed with standing water. Several large wetland complexes are crossed by Route 2 which are likely of sufficient of area to support breeding. Minimal impacts to appropriate wetland habitats would occur as a result of structure placement. Right‐of‐way clearing would increase the area of meadow and emergent habitat available for this species Impacts to individuals and appropriate habitat areas will be minimized by spanning wetland areas when possible and by applying BMPs to construction in wetlands. If an active nest is found during construction, potential impacts and avoidance will be assessed and coordinated with the appropriate agencies. Route 3 Alternative (Northern Route) No DNR observations of an American bittern have been made within one mile of Route 3. During the BGR surveys, one observation was made along Route 3, although American bitterns likely occur along the route in greater abundance where it crosses emergent wetlands interspersed with standing water. The CNF does not track this species. Several large wetland complexes are crossed by Route 3 which are likely of sufficient of area to support breeding. Minimal impacts to appropriate wetland habitat would occur as a result of structure placement. Right‐of‐way clearing would increase the area of meadow and emergent habitat available for this species July 2010 Environmental Consequences Page 5‐20
