The present paper has taken into account data from forest management plans realised during 1995-2007 for forests located in Forest Districts from the West Plain. The purpose of this paper was to analyse stands from their qualitative (age), structural (consistency, composition) and stational characateristics (altitude, slope, soil type). The black walnut species occupies a total surface of 714 ha being present in almost the entire area with the exception of Carei Forest District and with a focus in Ceala (457 ha) and Sacueni (176 ha) Forest Districts. These stands are present at altitudes between 80 and 400 meters, with an average of 150 m. The research has emphasized the fact that the black walnut’s age ranges from 2 to 130 years while their consistency is appropriate (0.7 - 0.8). However, barrelands stands are also present (0.4- 0.5). The black walnut’s participation in the stand’s composition is also varied, from 10 % to 100 %. Fluvisol is the representative soil for this species, while Arum-Pulmonaria is the main flora type. Silvosteppe mixed hardwood stand with pedunculate oak is the main forest typology for this species. Black walnut is a forest species with an exceptional economic value determined by its quality wood.The obtained results emphasize the fact that this species can be extended in the analysed area due to its numerous forest and environment qualities.
