Annually, the salt content (Electric conductivity ; EC) of the stem flow water, the crown drip water, and the rain water show two peaks in Okinawa ; one is in September, the typhoon season in summer, and the other is in November, the monsoon season in winter. The highest values of EC of the stem flow water and the crown drip water are those for the trees grown along the seaside. Especially in the typhoon season EC becomes markedly high. In general EC of the stem flow water is about1.38 times higher than that of the crown drip water. EC of the stem flow water is about 9.00 times higher than that of the rain water, and that of the crown drip water is about 5.70 times greater than that of the rain water.
