HYPERSALINE SOILS 



BRACKISH SOILS 



REDUCED VASCULAR PLANT PRODUCTIVITY 



. RELATIVELY OPEN CANOPY 



LIGHT PENETRATES TO SOIL 

 > INCREASED ALGAL PRODUCTIVITY 



INCREASED VASCULAR PLANT PRODUCTIVITY 

 AND HIGHER STANDING CROP 



LESS LIGHT PENETRATION 



> DECREASED ALGAL PRODUCTIVITY
