Résumé :	The relationship between density and cover of Santolina etrusca, a plant species endemic to central Italy, and some ecological and geomorphological features of river terraces were studied by univariate and multivariate analysis. The results showed that S. etrusca achieves maximum density and cover on the second river terrace occasionally disturbed by flooding and with chamaephytic vegetation. On the first terrace its distribution is limited by frequent flooding and on the third by competition. Since S. etrusca grows on all the terraces considered in this study, it is a poor indicator of the gradient of disturbance due to flooding. It is not highly adapted to disturbance by flooding nor to competition; nor is it potentially dominant if undisturbed.
