eHALOPH is a database of plants that show tolerance to a salt concentrations equivalent to about 80 mM NaCl or above. The database derives from HALOPH published by Aronson in 1989 – see the post ‘eHALOPH: a brief history’. eHALOPH includes those species that can complete their life-cycle in a salt concentration of at least 200 mM NaCl - defined as halophytes by Flowers and Colmer (2008). We define euhalophytes as those plants that can complete their life cycle in seawater concentrations of salt - around 500 mM NaCl.

In addition to the species database, eHALOPH also includes a large literature database on halophytes. This list is based on Aronson’s original references an extensive additional bibliography derived from a personal bibliography generated over the last 30 years (an Endnote library; T J Flowers). The bibliography is supplemented by records imported (on a monthly basis) from a search of the Web of Science.

eHALOPH and its bibliography are searchable and entries can be edited – see 'Using eHALOPH'.
