LUDINGTON, MICHIGAN, USA - 26 April 2026. A broadleaf tree flanked by young jack pine saplings lines the sandy shore of an interdunal vernal pond at Ludington State Park, their reflections mirrored in the amber tannin-stained water. The progression from saplings to mature tree against the bare dune face illustrates the slow ecological succession occurring in the park's dune hollows, where seasonal moisture allows vegetation to gain a foothold on otherwise shifting Lake Michigan coastal sands.
