Intertidal Wetlands - Spatial patterns

• Location: Intertidal wetlands are found in coastal areas of tropical regions where air temperature, wave action, salinity levels, and sediment movements are moderated by the locational features of the estuarine environment. They exist in a band between 32°N and 38°S of the Equator.

– Mangrove wetlands: along tropical and subtropical coastlines (25oN-25oS)
– Coastal Wetlands: in temperate areas (25oN-60oN and 25oS-60oS)
– Intertidal wetlands: in coastal areas of tropical regions, specifically between 32oN-38oN 

• Altitude: They exist within the limits of the coastal range. 
  

• Size, shape and continuity: The area covered by intertidal wetlands is determined by the limits of the tidal range and, increasingly, by human obstructions and imposed land restrictions.
