Apple snails are invasive freshwater snails that can reach high population densities and devastate aquatic vegetation. They pose a threat to rice crops, wetland habitats, and native snail species.
Apple Snails
The Japanese climbing fern is a fast-growing vine that forms dense mats, smothering and displacing native vegetation. It alters fire regimes, reduces sunlight penetration, and threatens the biodiversity of Louisiana's forests and wetlands.
