Soil-salinity Tolerant Plants - Coastal Region
Salinity in the Coastal Region | Salt-spray Tolerant Plants - Coastal Region | Photo Gallery | Glossary
Purpose
A list of salt-tolerant plants that commonly occur in the Coastal Region appear below. The estimated soil salinity classes in which each of these plant species is likely to occur has been noted. Because many species often grow across a range of classes, other salinity indicators may also be needed to increase confidence in identifying a particular salinity class from its assemblage of indicator species.
