Ellenberg - Salt

Ellenberg values for salt tolerance start at zero, corresponding to no tolerance of salt.

 

Ellenberg value 

Explanation

0

Absent from saline sites; if in coastal situations, only accidental and non-persistent if subjected to saline spray or water (most species)

1

Slightly salt-tolerant species, rare to occasional on saline soils but capable of persisting in the present of salt (includes dune and dune-slack species where the ground water is fresh but where some inputs of salt spray are likely) (Calystegia sepium, Chenopodium album, Oenanthe crocata, Sedum anglicum)

2

Species occurring in both saline and non-saline situations, for which saline habitats are not strongly predominant (Atriplex prostrata, Elytrigia repens, Phragmites australis, Rumex crispus)

3

Species most common in coastal sites but regularly present in freshwater or on non-saline soils inland (includes strictly coastal species occurring in sites such as cliff crevices and sand dunes that are not obviously salt-affected) (Cakile maritima, Cochlearia officinalis, Juncus gerardii, Spergularia rupicola)

4

Species of salt meadows and upper saltmarsh, subject to at most only very occasional tidal inundation (includes species of brackish conditions, i.e. of consistent but low salinity) (Atriplex littoralis, Elytrigia atherica, Glaux maritima, Triglochin maritimum)

5

Species of the upper edge of saltmarsh, where not inundated by all tides (includes obligate halophytes of cliffs receiving regular salt spray) (Aster tripolium, Crithmum maritimum, Puccinellia maritima, Suaeda vera)

6

Species of mid-level saltmarsh (Atriplex portulacoides, Cochlearia anglica, Limonium vulgare)

7

Species of lower saltmarsh (Spartina anglica, Suaeda maritima)

8

Species more or less permanently inundated in sea water (Zostera spp.)

9

Species of extremely saline conditions, in sites where sea water evaporates, precipitating salt (Salicornia europaea agg.; these could equally well be treated as species of the lower marsh)
