Vegetation data collected from Northeast Shark River Slough, Everglades National Park, Florida, USA, September 2006 - ongoing

This project was established in 2006 to document the pattern of abundance of key
ecological indicators (e.g., surface water, soil, floc, periphyton and sawgrass) across the
NESRS landscape (Gaiser et al. 2009). A total of 30 sites were established and monitored in
2006, 2007 and 2008 . After the completion of 1-mile bridge in 2012, additional 10 new sites
were established to observe the ecological impact of 1-mile bridge ( Known as Bridge &
Census sites). In 2015, additional 40 sites were established along eight transects (T1-T8,
known as near canal sites) in ENP marshes starting at, and roughly perpendicular to the L-29
canal. The purpose of these sites was to monitor the potential effects of Modified Water
Deliveries (MWD) operations on changing nutrient concentrations and ratios in key ecological
compartments due to increased downstream discharges from the L-29 canal beneath the 1-mile
and 2.6-mile bridges and culverts along Tamiami Trail.
