摘要: We examined the immediate effects of laurel wilt on redbay (Persea borbonia [L.] Spreng.) and stand-level characteristics in a mixed evergreen-deciduous forest at Etoniah Creek State Forest Florida. Percent mortality overstory, sapling, seedling layers were 100%, 30.2%, 1.8%, respectively, year after first signs infection observed. The diameter distribution shifted from reverse “J” pattern to where only remaining living stems 4-in. dbh. Mortality also resulted significant reductions overstory importance values density basal area. Our results suggest that (1) has more pronounced effect redbays than smaller (2) caused by can result modest but changes stand structure.
