After a pleasant ride on the Staten Island Ferry and transfer to the S51 bus we arrived at the NPS Gateway National Recreation Area at Fort Wadsworth to meet Mark Christiano, the GIS Specialist.

Mark led a very informative tour outlining the history of Fort Wadsworth including the different roles the site has played over time from the Revolutionary War to present day.

Restricting Fill in Jamaica Bay

This week the New York State Assembly and New York State Senate passed Assembly Bill A.2074A and Senate Bill S.3392A. This bill, which Broad Channel community activists Dan Mundy Sr. and Dan Mundy Jr., among others, have lobbied hard for over many years, prohibits the dumping of fill in the borrow pits of Jamaica Bay. This is specifically designed to permanently put to rest proposals that use the deep borrow pits in the bay (former dredge locations where sediment was taken to fill other sites such as JFK Airport) as repositories for dredged material from nearby projects such as the New York - New Jersey Harbor Deepening Project. Controversy over the quality of the dredged material and the efficacy of a cap to contain contamination has prevented the realization of these proposals up to this time. However there may be renewed interest in potential receiving areas in Jamaica Bay as the Harbor continues to expand. It is now up to Governor Cuomo to decide whether to sign the bill into law.

Black Wall Community Marsh Planting 06 01 14

White Egret Edgar has claimed the American Littoral Society Northeast Chapter Headquarters as his turf.

On a gorgeous Sunday a couple of weeks ago, over 50 volunteers were ferried out from Broad Channel to Black Wall Marsh Island. There waited a bucket of spades, work gloves for all and 5,000 plugs of Spartina alterniflora (plus a few distichlis spicata). These were all planted in rows three feet on center in the soft sand within just a couple of hours as the tide went out.

Even within the narrow elevation range of the island different sediment bands are visible.

image

Jamaica Bay Ecowatchers and the Northeast Chapter of the American Littoral Society organized the planting day. 

image

Black Wall Marsh (which had become mostly a sandy mound just above mean tide until the plugs were planted) is the second small island just west of the community of Broad Channel in Jamaica Bay. The photo above shows the view from the eastern edge of the island looking over open water to Rulers Bar Hassock (restored in 2012) and Broad Channel beyond. 

image

Horseshoe crabs marked the sand with their mysterious looking tracks. It is currently their mating season and they prefer just such gradual, sandy slopes. Many of them formed shallow lumps in the sand around the perimeter of the island.
