Terms to know:

Coastal Upland– mesic or xeric communities restricted to barrier islands and near shore; woody or herbaceous vegetation

Xeric- dry or low in moisture

Mesic- moderate or well-balance supply of moisture

Berm- a long narrow wedge of sand with the steep slope facing towards the sea

What is a

Coastal Berm?

Long narrow ridge of storm-deposited marine debris that is parallel to the shore

• Formed by a mixture of coarse shell fragments, coralline algae, and other coastal debris.

Threats to Coastal Berm

 Invasion of exotic species

 Human encroachment and development

 Storm disturbance

Management

 Fire is not a management tool in this habitat because it is rare to non-existent.

 Removal of invasive exotics

 Berm repair

 Preservation of existing berm habitat

 Restriction of real estate along coastal upland communities
