"After sediment from Sandy filled in a portion of the property, the owners sought and received initial permission from the state to remove its wetlands classification, potentially opening the door to residential construction."
This statement brought to mind many more questions than answers.
In light of climate change and rising sea levels does it make any sense to reclassify wetlands filled by natural events in order to develop them? Importantly, does this wetland have the ability to recover? How deep is the overwash deposition? Assuming that the overwash fan is not uniform in depth, and decreases as it moves inland, will only a portion of the affected area be reclassified? Alternatively, if all the overwash is significant, and there is little hope for a natural recovery, should it be reclassified as a dune or swale, and subject to protections other than ones provided for coastal wetlands?
Even prior to Hurricane Sandy it has become apparent that storm conditions have become less predictable and stronger that in the past. With this in mind, the importance of wetland to ameliorate surging flood waters, becomes increasingly important, especially on a barrier island. During a hurricane, especially on a barrier island, water cutting new channels and depositing sediment is not uncommon, and these normal, if undesired, events should not automatically trigger a hasty reclassification.
Studies on storm surge sediment deposition on wetlands date as far back to Hurricane Audrey in 1957. While most of the studies are focused on the Gulf Coast and Louisiana due to the size of the wetlands found at the mouth of the Mississippi, other areas were also studied, including in Florida in the 1990's and well as Texas and Alabama coasts in 2005.
In fact, a review of the literature suggests that the recovery of marsh species after a significant deposition of overwash is not entirely understood, but wetlands do have the ability to recover or even transition to a dune or swale ecosystem. In certain cases, the addition of sediment from a hurricane was beneficial, partially reversing wetland subsidence in coastal Louisiana.
In particular, the study titled "Recovery of a Louisiana Barrier Island Marsh Plant Community Following Extensive Hurricane-Induced Overwash" (1) was illuminating and concludes that Marsh plant recovery directly correlates to the depth of overwash. Recovery decreases when overwash deepens past 25 - 35cm, and eventually transitions to a dune or swale ecosystem when depositions reach past 50cm- 100cm.
Based on the lack of freely available information on the Holgate wetlands condition, and the known potential for wetlands to recover from storm induced overwash, the NJ DEP should strongly reconsider the wisdom of changing the wetlands classification for this property.

The Institute for Biodiversity Law and Policy at Stetson University College of Law just announced on the Ramsar mailing list that they will compile monthly a list of recently published articles discussing the Ramsar Convention and/or Ramsar Sites.
The Institute has created this list in order to facilitate research and provide timely, relevant article updates to the Forum members. The list includes online links to the articles, where available, and the Institute plans to update this list monthly.
To access the list in its entirety, join the Ramsar Forum mailing list here, I've already found a few interesting studies worth reading.
