SOILS: Setting below the road has the potential to generate a high amount sediment next to Class II stream with shovel logging; corridors accessing road and crossing Class IV stream should be reviewed and approved prior to logging. Use slash to support equipment and avoid rutting.
WETLANDS: Shovel yarding in wetlands adjacent to Class II stream buffer; use slash to support equipment and avoid rutting, follow BMP 12.5.
WILDLIFE: Wildlife corridor - retain elevational structure for corridor where possible.
