Limiting Nutrients - Nitrogen (nitrates)
Other preferences - Waterlogged, saline soil.
Nitrogen was reported to be limiting in many salt marsh ecosystems and added nitrogen resulted in increased primary production, decomposition and animal growth rates (Valiela & Teal, 1974; Long & Mason, 1983). Vascular plants communities are exposed to greater fluctuations in day and night temperatures than their marine counterparts, and are probably tolerant. In addition, flood tides result in temperatures shocks, e.g. in winter the frozen marsh surface may be exposed to tidal waters 10 °C warmer. Although temperature shock probably has physiological effects, they have not been studied (Adam, 1993).
