Salt Marsh Biome
Transcript of Salt Marsh Biome
Salt marshes are along the shoreline of the east coast, gulf coast and west of North America. Salt marshes are found in New England on the USA Atlantic Coast.
1. The sand content of the soil in the low marsh is less than ten percent because of how much organic matter is dissolved in it.
2. The rotten egg smell of the salt marsh comes from the anaerobic bacteria that break down the organic material.
3. Salt marshes are capable of trapping pollutants to protect the valuable estuaty systems.
4. A general rule for salt marshes is that the higher the tidal range, the higher the productivity of the marsh.
5. Salt marshes produce around twenty tons of biomass per acre.
6. Many invertebrate species are found in the salt marsh. They thrive in the low marsh area.
7. There are species of small crabs, including mud fiddler crabs and purple marsh crabs. Many mollusks, such as mussels and oysters, live in the low marsh too.
8. Others species in the low marsh include polychaete worms and periwinkle snails. In the upper marsh there are sand fiddlers and wharf crabs.

The highest temperature was 22 degrees in July and August while the lowest was 14 in the same months. the most precipitation happened during November and December.

9. Salt marshes form in shallow, quiet water, where the water is salty and still enough for the suspended particles to settle to the bottom.
10. These marshes are some of the most productive lands in the world and produce so many organic nutrients that their influence can be seen far out into the coastal ocean waters.
11. Marshes are based on one plant, the Saltmarsh Cordgrass, which helps stabilize the environment so that many other plants and animals to move in.
12. Other plants including Cordgrass, Saltmeadow Grass, Blackgrass, Bullrush and Sea Lavender add color and variety to the marsh and grow in zones according to their tolerance (or ability to handle the saltiness) of the tidal water.
13. Among the grasses, mats of algae grow in the upper layer of soil.
14. Crabs, snails, insects and muskrats (partially aquatic rodent) are common inhabitants.
15. Snakes and turtles abound, and fiddler crabs pop out of their burrows to find dinner after the tide goes out.
16. Birds such as the Northern Harrier (marsh hawk) and the marsh hen are also common to salt marshes.
17. Mangroves take over from salt marshes in the lower latitudes, filling many of the same functions, although they aren't as productive.
Tidal Flow Link:
Causes and Effects
Mosquitos by the droves.
Polluted coastal waters. Increased storm surge vulnerability.
Loss of habitat for crabs, shellfish and vast numbers of beautiful bird species including sparrows and rails.
They provide important services such as floodwater storage and storm protection for coastal cities such as New Orleans.
Healthy marshes also serve essential roles in carbon sequestration.
a service of primary concern at current emission rates of the greenhouse gas carbon dioxide.
nutrient removal and water purification.
global climate change and sea level rise, agricultural and industrial development and loss of sediment supply are contributing to dramatic rates of wetland loss worldwide.
