Salinity and Flooding Affect Mortality of Atlantic White-Cedar (Chamaecyparis thyoides) Seedlings

Atlantic white-cedar (Chamaecyparis thyoides [L.] Britton, Sterns & Poggenb.) seedlings in pots were subjected to four levels of salinity in irrigation water (0.0, 0.1, 0.2, or 0.4 percent) with either continuous flooding or irrigation as needed. Mortality of continuously flooded seedlings with 0.4, 0.2, and 0.1 percent saltwater was 100 percent after 2, 4, and 8 months, respectively, compared with 20 percent mortality for seedlings flooded 17 months with fresh water. For seedlings irrigated as needed, mortality after 17 months was 100, 85, and 40 percent for 0.4, 0.2, and 0.1 percent saltwater, respectively, compared with 5 percent for seedlings that received fresh water. Results have implications for site selection for regeneration or restoration with Atlantic white-cedar in areas affected by rising sea level.
