Wetland Impairment Assessment - Meadowlands Research & Restoration Institute

Problem

There have been comprehensive studies and planning documents in the past three decades regarding the wetland enhancement in the Meadowlands. These documents indicate the need to measure the physical and ecological impairments to ecological function and to perform plant biodiversity assessments as a first step towards wetland enhancement. Seven tidal wetland sites totaling one hundred and five hectares (105 Ha) were selected to measure ecological function and impairments, including the nature and extent of invasive species, lack of plant diversity, lack of tidal exchange, and habitat fragmentation.

Objectives

Create a plan for better wetland enhancement and restoration by identifying quantifiable restoration metrics and gathering strategic data to select sites appropriate for acquisition and wetland enhancement and restoration.

Strategy

We propose to use a combination of traditional field monitoring techniques along with remote sensing methods and modeling to characterize species diversity, habitat fragmentation, and hydrological restrictions as a way to measure impairments to wetland function.

Activities

Measure flora diversity and vegetation cover
Acquire and classify high resolution hyperspectral images as well as the balloon imageries of the sites
Acquire Light Detection and Ranging (LiDAR) images of the sites
Measure hydrologic and hydrodynamic data to characterize hydrological restrictions
Collect the bathymetry data
Complete watershed delineation using LiDAR derived Digital Elevation Model (DEM) and water flow model
Analyze habitat fragmentation

Deliverables

A series of maps, tables, and animations describing wetting periods and topography, species diversity, plant assemblages, wetland indicator status for each species, plant rarity scores, and species patchiness
A high resolution DEM to model and visualize tidal flow at each site
A master matrix of measured parameters and metrics will include scores on acquisition and enhancement priorities
