Attachment_3-_Helena_Mastication_Map.pdf

This file is a project location map for the Grand Bay National Wildlife Refuge (NWR) - Helena Mastication Treatment Area. The map depicts a 296-acre project area located near Helena, shown in red outline on an aerial photograph. The project area encompasses multiple non-contiguous parcels within and adjacent to the refuge boundary, with the main treatment zone in the upper portion and several smaller treatment units distributed throughout the lower sections. The map includes legend elements identifying disc lines, utility rights-of-way (ROW), refuge roads, and the overall project boundary. A scale bar indicates distances in miles (0 to 0.5 miles), and a compass rose shows cardinal directions. The project area appears to involve vegetation management or treatment activities, as indicated by the "Mastication Treatment Area" designation, which typically refers to mechanical chipping or grinding of woody vegetation. Utility corridors and existing refuge infrastructure are marked to show clearance requirements and access considerations for the proposed work.
