Abstract:	The object of this paper is to broaden and deepen the knowledge referring to the notion of superior limit of the forests, of the types of superior limits, the analysis of the manner in which the limit beech forests from the Gutâi Mountains represent the superior limit of the forest. Another objective was a description of the main characteristics of this brush. The forests from the Oaş – Gutâi – Ţibleş Mountains are almost entirely represented by natural mountainous beech forests which held the majority in the forest massifs from this zone and cover an area of about 65.000 hectares. The aim of the article is to make an analysis substantiated ecologically referring to the aspects connected with establishing the notion of superior limit of the forest, of the types of superior limits, of the measure in which the limit beech woods from the Gutâi Mountains represent the superior limit of the forest and the description of the main particularities of these brushes. The mountain beech woods belong from an administrative point of view to the Baia Mare Forestry Direction and represent about 80% of the total of the woods from the zone of the Gutâi Mountains. The superior limit of the forest is defined by the line that connects the points of maximum altitude, in which the forest achieves a consistency of minimum 0.5, the trees are at least 5 m tall, and the minimum accepted area is at least 250m2. The limit brush from the Gutâi Mountains represents the superior natural climatic limit of the beech woods, conditioned by the dominant winds from the vegetation season, as the brushes meet the conditions of minimum area (250m2), of minimum 0.5 consistency and have the minimum average heights of above 5m (between 7.19 m and 7.94 m). Besides the dominant winds, the superior limit of the beech woods is also conditioned, but to a lesser extent, by the geomorphology of the land, very large slopes and by reasons of climatic and edaphic reasons.
