===Salt Tolerance===  

The categories of Low, Medium and High are indicative of the tolerance of plant species to salt exposure and/or uptake. Plant species with low salt tolerance should not be used in any LID practice that receives runoff from salted roads and parking lots. Species with medium salt tolerance can be utilized in LID practices that will be receiving road runoff but should not be in the line of salt spray or be receiving the bulk of the runoff. Species with high salt tolerance should be planted in LID practices that receive road or parking lot runoff that routinely contains road salt.  Few plants are truly halophytic or “salt-loving”.  in most cases elevated salt levels are temporary and precipitation quickly dilutes and removes salt from the soil profile. The Master Plant List includes some species that are recommended for planting should be planted in LID practices that are likely to receive road or parking lot runoff.
