Abstract

In the present study, the structure and diversity of the trees in the urban area of the city of Montemorelos, Nuevo León, (northeast of Mexico) were characterized. The trees of all the ridges and urban parks were enumerated. Total height (h), normal diameter (d1.30 m) and crown diameter (k) of the tree vegetation were evaluated and its abundance (Ar), dominance (Dr) and frequency (Fr) were calculated. In addition, the importance value index (IVI) of the tree species was estimated, and their diversity was evaluated with the Margalef (DMg), Shannon (H’), Real Diversity (1D) indexes as well as the green area per inhabitant. A total of 918 trees of 13 species, belonging to 11 genera, were registered, of which seven were exotic. The green area per habitant was 0.87. The Fraxinus americana had the highest IVI (53.82 %.), followed by Quercus virginiana (21.37 %). The urban trees had a higher proportion of tall organisms (between 4 and 6 m), and a normal diameter of medium size (between 20 and 30 cm); likewise, the community registered a Margalef index (DMg) of 1.9, a Shannon diversity (H’) of 1.17 and a Real Diversity index of 3.22. The urban green area per habitant is less than that recommended in previous studies, and with low diversity compared to other green areas in different locations.
