Fig. 12.3. Monthly evapotranspiration, leaf production, tree ring formation,
and litterfall during the period 1982-1993 simulated
using actual climate data.
Leaf and tree ring formation show two main periods
in spring and autumn, according to the transpiration
pattern which is characteristic of the Mediterraneantype climate. Litterfall shows
a single peak in summer
when water stress is higher
