The aim of this work was to test the efficiency of the use of simple moisture content (MC) measurements of cork oak leaves to provide interesting information on the stress induced by bark stripping. For this purpose, six mature and productive trees representative of the dominant and typical cork oak trees from western Mamora forest (10 km North of Rabat, Morocco) were selected. 2 non-stripped trees served as controls and 4 trees were bark stripping with different bark stripping coefficients (BSC). The MC of leaves was measured before and after bark stripping. During this study, a progressive decrease in MC measurements of the leaves was observed while the MC of non-stripped tree leaves remained almost constant. A close relationship was found between BSC of cork oak trees and MC of leaves.
