Abstract

The distribution of Raunkiaer life forms along rainfall and temperature gradients was determined for the floras of 27 geomorphological districts in Israel. Phanerophytes and chamaephytes are relatively strongly represented in districts with very low rainfall, decrease up to 150 mm and 400 mm of mean annual rainfall respectively, and remain more or less constant at higher rainfall figures. Hemicryptophytes and geophytes increase along the rainfall gradient. Therophytes show an optimum between 200 and 500 mm of rainfall. The distribution of life forms is less clearly correlated with mean annual temperature, though hemicryptophytes and geophytes show a negative correlation with mean annual temperature and with mean annual minimal temperature.
