Urban trees are an important resource for the ecosystem services they provide. The objective of this study was to determine the structure, composition, richness, and diversity of urban trees and shrubs in the city of Pampas, Huancavelica, Peru. Trees and shrubs in two avenues, four jirones (green verges), the main square, and an ecological park were evaluated, and their normal diameter at a height of 1.30 m from the ground, crown diameter, and total height were measured. Abundance, dominance, frequency, area, and volume (Importance Value Index) were determined. Likewise, the Shannon diversity Index, the Margalef Index, and the number of key species were calculated. Thirteen species, distributed in 12 genera and 10 families, were recorded. 69 % accounted for introduced taxa, and 31 % for native taxa. The family with the most significant presence was Rosaceae, with three species. The analyses of diameter and height classes showed a higher proportion of individuals with high diameters (>5 cm and <40 cm) and intermediate heights (h>1 m and <7m). The urban areas reported low to moderate species richness and diversity. In conclusion, the need for improved management of urban trees and shrubs in the city of Pampas is highlighted. The use of species native to the region should be prioritized, and attention should be given to risk factors affecting the public infrastructure.
