Résumé
The Baer-Bassit and Alaouite Mountains are in north-west Syria. The Jebel Alaouite is composed of Jurassic and Cretaceous calcareous rocks, running north-south and culminating on 1580 m. The Baer-Bassit is hilly country with green rocks. The climate is of Mediterranean type. Soil genesis and classification and degradation by the action of man were studied. Nahal. related soil characteristics to the vegetation. The flora already showed its most prominent traits in the Pliocene. The pluvial periods during the Quaternary influenced its distribution ; their effect was still visible.

Directions were worked out for the rational management and exploitation of the forests of Pinus brutia Ten., still in good condition, and the re-establishment of remnant forests of Abies cilicica (Ant. et Ky.) and Cedrus libani A. Rich.

The work closed with a synsystematic and synecological study of the most important tree association of Syria, the Pistacieto-Quercetum calliprini. The importance of the progressive and regressive phases of photodynamic successions for the forester was pointed out.
