Holland Red Maple Swamp features a northern hardwood swamp and a northern wet-mesic forest located within the Holland Wildlife Area. The hardwood swamp is dominated by red maple, green ash, and black ash with occasional swamp white oak and tamarack while white cedar dominates the wet-mesic forest. The ground flora contains small-spike false nettle, pale touch-me-not, common lady fern, royal fern, and crested wood fern. The site is recovering from logging nearly 100 years ago with an average tree diameter between 10-15 inches. Animals include fox squirrel, red fox, gray partridge, woodcock, and ruffed grouse. Holland Red Maple Swamp is owned by the DNR and was designated a State Natural Area in 2002.
