Iquitos is one of the most important cities in the Peruvian Amazon. It is well-known around the world for tourism, scientific research and cultural attractions. One challenge is assuring the sustainability of urban trees. This encourages the general goal of maintaining a balanced variety of urban structures and park areas with trees. This paper considers techniques for measuring the amount of urban forest in the monumental areas, using the Forest Value Index, Simpson index, Shannon-Wiener index, coefficient of Sorensen similarity and Cox index and create an urban forestry diagnosis. Most of the species growing alongside the streets are Terminalia catappa, Ficus benjamina and Syzygium malasccense. According to Forest Value Index most of the urban parks contain over 50% Couepia subcordata, Pritchardia hardyi, Syzygium malasccense species. Simpson dominance is low with values of SI’=0.1551 and SI’=0.1719 in street and parks respectively. There was not a meaningful statistical difference. In the context of the Shannon-Weaver index, the diversity is low with values of H’ =2.151 and H’ = 2.127 again there is no meaningful statistical difference. A species diversity of q D = 8.59 y q D = 8.39 is shown effectively. Likewise, the Sorensen similarity index among the species is determined to be 57.78% within the urban ecosystem. The space distribution, is “the added” type for the 10 most abundant species in the streets of Iquitos. In conclusion, the streets have a majority of young specimens representing 46% of the total population. This indicates that there is a potential to insure the long-term presence of urban trees. The parks, however, contain a larger number of adult trees with 46.0% represented in this category.
