This structural tree thrives in excessively wet soils, swamps, and along watercourses, possessing the ecological ability to fix atmospheric nitrogen into the soil through root bacterial symbiosis and features dark green leaves that are sticky when young.
• Black alder — A species of tree from the Betulaceae family (Alnus glutinosa), featuring dark brown-blackish bark that cracks with age, and subround, obtuse, or slightly notched leaves at the apex, sticky when young.
