Climate Change Vulnerability Assessment: Salt marshes (New Hampshire)

This habitat¹ was described as vulnerable to climate change because of the following factors:

• Sea level rise will inundate low marsh, and convert high marsh to low marsh
• Shifting precipitation patterns could increase erosion of salt marsh channels
• Damaging extreme storm events
• Lower salinity due to increased precipitation may benefit invasive species
• Human response to sea level rise in the form of infrastructure will restrict tides and prevent salt marsh migration

¹Note that the New Hampshire habitat CCVA did not specify between low and high marshes in their assessment
