Description: Shortleaf pine (Pinus echinata Mill.) grows in association with many other woody species, particularly understory hardwoods, which compete with it, limiting its productivity. Along with other species, sweet-gum (Liquidambar styracifua L.) is a major competitor on better-quality sites but decreases rapidly in importance as pine site index (SI) decreases and pine overstory increases.
