<p>The EPA Region 2 Long Island Sound Office (LISO) hosts the National Estuary Program and Geographic Program, the Long Island Sound Study (LISS). The LISS is bi-state partnership consisting of federal and state agencies, user groups, concerned organizations, and individuals dedicated to restoring and protecting the Sound.</p>
<p>The polygon indicates the adjusted eelgrass habitat suitability index model. The Long Island Sound Eelgrass Habitat Suitability Index, developed by Dr. Jamie Vaudrey in 2013, scores sites best suited for eelgrass growth. The polygon shows identifies a score based on the following parameters: depth, tidal amplitude, percent light reaching the bottom, temperature, dissolved oxygen, sediment grain size, and sediment total organic carbon. This adjusted eelgrass habitat suitability index model uses new water temperature data. The 2013 model used open Sound water temperature data from 2009 - 2011, while this model uses embayment water temperature data from 2019 - 2021.</p>
This EPA R2 LISO content item depicts the adjusted eelgrass habitat suitability index for Long Island Sound embayments developed by Ben Lawton (2023).
