Potential negative impact to forest<br />

plants and animal species due to<br />

permanent tree clearing; may<br />

introduce earthworms into ROW which<br />

could alter duff layer and have<br />

negative impact on understory plants;<br />

may introduce weed seed during<br />

construction and long term<br />

maintenance of the ROW; may allow<br />

invasion by cowbirds on cleared ROW,<br />

with potential negative impact to<br />

forest edge songbirds due to predatory<br />

nesting. The project will include best<br />

management practices to avoid and<br />

minimize potential negative impacts to<br />

forest species.<br />

Potential negative impact to<br />

forested wetland species<br />

due to forest clearing;<br />

minimal negative impacts to<br />

all other wetland species<br />

since most wetlands will be<br />

spanned by the project. The<br />

project will include best<br />

management practices to<br />

avoid and minimize<br />

potential negative impacts<br />

to wetland species.<br />

Forest clearing may result in<br />

increased habitat available for<br />

grassland species, depending on<br />

long‐term maintenance required<br />

for the Project; depending on<br />

location, herbicides may be used<br />

to control regrowth of trees that<br />

may interfere with transmission<br />

line; some incidental takes of<br />

nests may occur depending on<br />

the timing of construction. The<br />

project will include best<br />

management practices to avoid<br />

and minimize potential negative<br />

impacts to grassland species.<br />

Temporary clearing of shrubs<br />

required for construction,<br />

with regrowth allowed postconstruction.<br />

Impacts to<br />

shrubland species would be<br />

temporary and short term (up<br />

to several years until<br />

regeneration occurs). The<br />

project will include best<br />

management practices to<br />

avoid and minimize potential<br />

negative impacts to shrubland<br />

species.<br />
