| Impact Description | Alnus glutinosa (black alder) leaf litter easily leaches nitrogen and water-soluble organic substances. Black alder could further impact water courses by de-oxygenating the water, shading out other species, and degrading habitat. Black alder’s dense root system is capable of trapping sediment and subsequently altering water flow in wetland ecosystems. |
