Soil Salinity Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater‚ due to rainfall or irrigation‚ can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and

St. Helens‚ a stratovolcano in western Washington‚ erupted. The eruption scoured the slopes of the volcano removing vegetation and soil from the vicinity of the mountain. 32 years after the eruption‚ vegetation has returned to the mountain. The author’s main interest in this field is the methods by which vascular plants re-establish themselves after cataclysmic‚ soil-removing volcanic eruptions‚ and if some plants are better suited than others to re-establishing on volcanic tephra and other eruptive
