Abstract

During the months of August, September, October and November 2017, the afforestation of drainage channels 2, 3, 5 and 7 was inventoried in a quantitative and qualitative way, with the aim of identifying the richness and abundance in the distribution of species throughout its extension. 61 species were recorded, totaling 1214 individuals, belonging to twenty-seven families. Fabaceae, Myrtaceae and Bignoniaceae were the most numerous with ten, nine and eight species respectively. In channel 2, 408 individuals belonging to 40 species were recorded, the most abundant species being Guanandi Calophyllum brasiliense Cambess (n=183).The count in channel 3 obtained 312 individuals belonging to 33 species. The Jambolão Syzygium cumini ( L.) Skeels stood out numerically (n=118). In channel 5, 304 individuals were recorded, belonging to 34 species, including Inga Inga laurina. (Sw.) Wild. (n=96) the predominant species. In channel 7, 190 individuals belonging to 31 species were recorded. The most numerous species was the Ipê-cascudo Handroanthus chrysotrichus Mart (n=29). Ten species were not identified. The high frequency of a few species planted in sequence was the pattern obtained in the analysis of the distribution of specimens. Regarding origin, the number of exotic species was 32, regional natives 20 and non-regional natives 9. The majority of species (n= 36) have zoochoric dispersion syndrome. The objective of carrying out this inventory was to provide data to be considered in the maintenance and planning of the municipality's green areas, which should prioritize the use of regional native species to conserve and connect the different areas that make up the urban forest of the municipality of Santos.
