Green areas and trees in the urban zone of the Pedro Carbo canton, province of Guayas, Ecuador

Abstract

In Pedro Carbo, the green areas and urban trees maintain the dynamics in the green spaces of the province of Guayas, with the successful settlement of timber and non-timber forest trees in the parks that provide great benefits for the population, being a problem the m²/inhabitant green areas. For this reason, this research was carried out to evaluate the green areas and trees in the urban area of ​​the Pedro Carbo canton. In them, a forest inventory was carried out with dendrometric information for the identification of botanical families, tree species, determination of m² of green areas and tree canopy; With the total area of ​​green areas and the total urban population, the urban green index was calculated, obtaining a value of 0.45 m²/inhabitant. The index of ecological importance value, richness of Margalef, diversity of Simpson was also calculated. and Shannon-Wiener. A total of 10 species was recorded with 137 individuals belonging to seven botanical families, the most representative being Aracaceae. It was possible to determine 9,273 m² of green areas distributed in 8 parks and a plaza where 1,805 m² correspond to the net area of ​​tree cover, the species with the highest index of ecological importance value was for Euterpe oleracea Mart, and the lowest was Caesalpinia pulcherrima (L.) Sw., Margalef reflected an ecosystem with low anthropic level and low diversity of species, Simpson with average diversity and Shannon with diversity half.
