摘要: Spartina alterniflora was transplanted into dieback areas of a salt marsh in southeast Louisiana at two elevations (ambient and +30 cm) with without macro- (N, P, K) micronutrient (Fe, Mn, Cu, Zn) additions to determine if transplant success is dependent on increasing elevation or nutrients.Spartina elevated plots had more than twice the above- belowground biomass as compared nonelevated after three months growth. Additionally, there significantly vegetative reproduction (greater culm density number newly produced culms) ambient elevation. Macronutrient increased densities only plots.Spartina lower survival rates even when transplants received nutrient additions. These results suggest thatS. may be successfully degraded salt-marsh increased. The addition nutrients concomitant increase not sufficient for success.
