Deep in the heart of the Brosnan Forest located in Dorchester County, towering longleaf pines stretch across the vast 14,400-acre ecological preserve. The air thickens with the scent of pine needles as damp soil softens underfoot. A cacophony of squawks, chirps and calls echo through the air. In constant battle with the glaring and looming sun above, a team of regulatory specialists from the Charleston District push through and navigate the habitat terrain by foot on a crucial mission.
