species have been seen to increase or decrease the salinity in the tidal saltwater marsh system. When Mesembryanthemum crystallinum also known as the crystalline ice plant dies it releases stored salt from epithelial cells (Wikipedia 2015) and it is redistributed in the soil surface (Vivrette and Muller 1977). Release of salt or other nutrients from dying invaders is not the only affect the dead vegetation has on the tidal saltwater marsh. Invaders that produce more below and above ground biomass can

This is proven in Document D, “The [ship] and her lifesaving cargo returned

the effects related to groundwater depletion is the Floridian Aquifer. The surface water flows have been reduced partly because of the saltwater intrusion that is occurring in the coastal areas of Brunswick and Savannah, Georgia, and Jacksonville and Miami, Florida. In central Florida the commercial and residential development has ultimately led to saltwater intrusion which has at times taken on in the form of sinkholes. There is also great concern about surface-water depletion from lakes in the area
