Bemidji – Grand Rapids Biological Assessment and Evaluation clearing of forested areas within 250 feet of known populations of Botrychium mormo. Where route shifting is not possible, the Applicants will seek take permits and negotiate appropriate mitigation with the appropriate agencies. 5.3.7 Woodlands This guild includes fourteen TE plant species that have potential to be found within these communities: • Botrychium dissectum – dissected grape fern • Botrychium minganense – Mingan moonwort • Botrychium pallidum – pallid moonwort • Botrychium rugulosum – ternate grape fern • Botrychium simplex– least moonwort • Comptonia peregrine – sweet fern • Hierchloe odorata – sweet grass • Pinus strobus – white pine • Viola novae‐angliae – New England violet • Waldsteinia fragaroides – barren strawberry 5.3.7.1 Description of Habitat <strong>Type</strong> Woodlands habitat types include upland areas with open grown trees with canopy openings, partial shade partial/sun. Community types include jack pine woodlands, aspen woodlands, oak woodlands and savannas and recently disturbed (logged, burned, large scale windthrow, etc.) forest areas. Woodlands in the CNF area occur as early successional communities. Historically fire maintained these communities, though more commonly they occur as post logging landscapes or on thin, rocky soils of the Canadian Shield or poor sandy soils in outwash areas. Typical tree species of the early successional conifer woodlands include jack pine and red pine with oaks and aspen common. Conifer woodlands are intermediate between conifer shrubland and conifer forest. Deciduous woodlands are typically dominated by quaking and big‐toothed aspen with bur oak and green ash common. Deciduous woodlands are transitional communities between forested communities and prairie or savanna. Many of the communities that resemble natural woodlands in Minnesota are post logging or grazing communities. The species included in the guild consideration are typical of natural woodlands but also occur in human created types that resemble natural woodlands. 5.3.7.2 Direct and Indirect Effects Potential indirect effects include increased light availability and associated alteration of ambient temperature and moisture in localized situations where scattered overhead canopy is removed. Additionally, introduction and facilitation of invasive plant species movement is a potential effect. Removal of canopy removes shade cover, increasing light adjacent to cut areas. Areas adjacent to clearings are likely so see a change in species composition from plant species adapted to partial sun/shade to those tolerant of openings. In most cases, woodland communities along the proposed routes are the result of past and present timber harvests and species of this guild are known to occupy habitats with abundant light availability. All of the species in this guild are known to occupy openings as July 2010 Environmental Consequences Page 5‐101
Bemidji – Grand Rapids Biological Assessment and Evaluation well as woodlands, and in some cases thrive in open conditions. Individuals of this guild adapted to some overhead canopy may be temporarily adversely affected by tree removal, but are likely to persist in a post project scenario where ongoing management typically creates brushy shrubland settings under transmission lines. Opening of woodlands may provide additional pathways for invasive species typical of openings. Route 1 Alternative (Great Lakes Pipeline) Woodlands and areas that resemble woodlands occur along the entire Route 1 area. Logging has taken place along this entire route, and regrowth forests that resemble natural woodlands are present where recent logging has occurred. Natural woodlands would have occurred on thin, rocky to sandy soils, typically both east and west of the Ten Section area. • Two individual Botrychium dissectum plants were observed in nearby locations west of Six Mile Lake along the edge of the Great Lake Pipeline corridor and another along the Enbridge corridor near the Mississippi River. CNF data indicates that this species is present west of Cass Lake within the Great Lakes/Enbridge Corridor. • Botrychium minangense was observed during EP surveys in nine locations along the Great Lakes corridor. DNR data identifies five populations, and CNF data indicates two populations within this route. • Botrychium pallidum was observed in six locations with 31 individual plants observed during EP surveys. • A new population of Botrychium rugulosum was observed once during 2009 surveys in an area near the previously known location. CNF, DRM and DNR data record a single observation of Botrychium rugulosum on Route 1 just west of the Mississippi River. • One hundred ten Botrychium simplex individuals in 9 populations were identified within this route during Great Lakes Pipeline surveys along cleared corridors. • Pinus strobus is found in all age classes in forest habitats along Route 1 and is present in young forests along this route. Woody species would be cleared within the work space of the project during construction and periodic maintenance along the transmission line corridor will prevent future canopy closure. These activities will directly affect some of the known occurrences for species adapted to shaded conditions as areas will be exposed to additional direct sunlight. All of the species this guild are adapted to at least partial sunlight and some species to full sun. Prior to construction, field surveys will be conducted to identify populations of species in this guild. Where possible, populations will be spanned, and maintenance will allow for regrowth of short stature species. Individuals of this guild may experience adverse affects where these individuals have adapted to partial shade environments. Where impacts are unavoidable, the applicant will obtain necessary take permits and negotiate appropriate mitigation. Route 2 Alternative (US 2) Woodlands and areas that resemble woodlands (due to logging) occur along the entire Route 2 area. Logging has taken place along this entire route, and regrowth forests that resemble natural woodlands are present where recent logging has occurred. Natural woodlands would have occurred on thin, rocky to sandy soils, typically both east and west of the Ten Section area. • Botrychium dissectum was observed in one location during EP surveys and in two locations during 2009 surveys along Route 2.
