PROJECT STATUS REPORT as of 18-May-2022

Freshwater Floating Marsh Creation Demo COMPLETE

PROJECT LOCATION:

PROJECT DESCRIPTION:

The project will develop and test unique, previously untested technologies for creating floating marsh for potential use in fresh and intermediate zones.

PROJECT STATUS: (Project Status Last Updated: 10-Jun-2009 )

The deployed vegetated structures at the Mandalay field site have been in place since Spring 2006, and are functioning as designed. By the end of 2008 (the third growing season in the field), vegetation in the floating structures has spread significantly from their mother structures and are beginning to interweave with plants from adjacent structures, and the belowground plant material was generating an increasingly extensive network of the fibrous roots and rhizomes necessary to establish the foundation of a sustainable organic marsh mat. Some of the deployed structures at Mandalay were damaged, but overall the project structures and associated vegetation weathered the storms well with less than 5% of the structures damaged or lost. In this project, the P. hemitomon plants established in the floating structures performed extremely well in the areas not impacted by increases in water salinity from storm induced high water, and when protected from nutria grazing.

FUND STATUS:

The current project estimate is $1,068,602 , which includes $613,725 for construction first costs, and $419,585 and $35,292 for 20 years of monitoring and operations and maintenance, respectively.
