Avalon's Dunes

In our second installment of looking at plants in Avalon, NJ, we go from the garden to the dune, much more fun. I didn't walk on the dunes, mind you. Just along the designated pathways.
Dunes! Filled with grasses and forbs.
Maybe the most famous dune occupant, beach grass (Ammophila breviligulata). This is the species that is planted in rows whenever there is an effort made to save the beaches from erosion. Through its extensive root system, beach grass binds the loose sandy soils together. This stability allows other plants to colonize the dunes. Avalon has been preserving it's dunes for over 30 years. (They are allowing new development in the salt marshes, however, but that's for another day).
This is a neat plant, trailing wild bean (Strophostyles helvola). It's uncommon in New York City, but fairly common in NJ - because it loves these outer coastal plains. It's a ground-trailing vine in the pea family. This plant is very similar to
pink wild bean (S. umbellata), which is rare in NY State.


Note the fruits are encased in bean-like pods.
