ite and for each offsite parcel or corridor. • Discussion of wetland impacts and their effect on the functions and values of wetlands. • Discussion of construction BMPs that may be used to protect wetlands (e.g., buffers, mats, seasonal work limitations, signage, barriers, special erosion, and sedimentation control methods). • Discussion of applicable Federal, State, and local wetland permit requirements and status of the application(s). • Discussion of anticipated wetland mitigation. If possible, provide a tabular comparison of possible wetland losses and mitigation gains using a common metric such as functional service units (preferred approach) or acreage. Wildlife Qualitative discussions of possible effects on terrestrial wildlife are generally sufficient for an ER. However, evaluations should be based on quantitatively estimated causal factors (e.g., noise levels, structure heights, and corridor widths). The ER should include a discussion of the following: • Possible mortality or physical injury to wildlife, especially immobile or weakly mobile species or life stages (e.g., eggs and juvenile stages). • Increased traffic from construction workers that might injure terrestrial wildlife. The proximity of traffic to habitat and possible routes of wildlife movement should be considered. • Noise from building activities that could startle wildlife or alter behavior (e.g., feeding, sheltering, movement, and reproduction). • Habitat losses or degradation that could reduce carrying capacity of habitats in the surrounding landscape. • Habitat losses and fragmentation that may affect movement and migration of wildlife. • Tall structures or equipment (e.g., cranes) that might injure birds and bats, considering height and proximity to migration routes and areas of wildlife concentration. Important Species and Habitats The ER should include discussions related to the effects of building the proposed project on important terrestrial species and habitats:
