Meltzer Woods is a 48-acre old-growth forest in central Indiana whose significance rests on both its ecology and its long preservation within a family farm. The surrounding land began with 160 acres bought by John Frederick Meltzer in 1857 and was expanded to 280 acres by Brady and Philip Meltzer in 1920. The 48 acres that had never been cleared were later protected through Indiana’s Classified Forest Program beginning in 1928 and were named a National Natural Landmark in 1973. Still cared for by the Meltzer family with the Central Indiana Land Trust, the woods now face persistent threats from invasive plants such as purple winter creeper and garlic mustard.
