| Title: | Percent cover measurements of four site-dominant species from the GCE-LTER Seawater Addition Long-Term Experiment (SALTEx) Project | ||||||||||||||||||||||||||||||||
| Abstract: | SALTEx (Seawater Addition Long-Term Experiment) is a field experiment designed to simulate saltwater intrusion in a tidal freshwater wetland to predict how chronic (Press) and acute (Pulse) salinization will affect this and other tidal freshwater ecosystems. The SALTEx experiment was initiated in 2012 and consists of 31 field plots, each 2.5 m on a side. There are three treatments (Press, Pulse, and Fresh) and two types of controls (with and without sides), each consisting of six replicates. The Press treatment plots receive regular (4 times each week) additions of a mixture of seawater and fresh river water. Pulse plots receive the same mixture of seawater and river water during September and October, which is historically a time of low flow in the river when natural saltwater intrusion occurs. The Fresh treatment plots receive regular additions of fresh river water. Treatment water is added during low tide to facilitate its infiltration into the soil, and all plots are inundated by astronomical tides at high tide. Percent cover was measured for four site-dominant species (Zizaniopsis miliacea, Pontederia cordata, Persicaria hydropiperoides, and Ludwigia repens) each July from 2013 to 2022. | ||||||||||||||||||||||||||||||||
