Observation Narrative	This dune ridge is of relatively recent origin - apparently less than 100 years old. Currently this ridge is > 100 m from the bay shore. The young landscape attests to the dynamic nature of this barrier beach landform. Plants such as Ammophila breviligulata thrive on young dunes such as this. The rare grass Aristida tuberculosa thrives on more open, sandier portions of this dune.
