What are the abiotic factors in salt marshes?

The abiotic factors in salt marshes  include:

1. High, variable  salinity

2. Low oxygen levels

3. Turbidity

4. Varying temperature

5. Sulphide toxicity

Salt marshes occur in zones between low and high tides. Salt marshes are periodically flooded by tides , so the plants living there have had to adapt to being submerged in salt water.

 Only a limited number of plant and animal species can tolerate the harsh conditions of salt marshes  and therefore salt marshes are generally poor in species.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
