| Summary: | In Mexico, most of macroscopic organisms, with few studies on species of microflora, in spite of the high importance they bear in ecological and economical values and the properties of interest that they hold for the health sector. In the context where this research was carried out, the Natural Protected Area of Xochimilco and San Gregorio Atlapulco Ejidos in Mexico City, this pattern is repeated. There are a very small number of studies on Xochimilco’s channel microalgae and no research of this nature has been carried out in San Gregorio Atlapulco. The aim of this work was to develop an inventory of microalgae Xochimilco and San Gregorio Atlapulco canals. In of the case of Xochimilco, a comprehensive review of literature related to microalgae studies ranging from January 1933 to December 2014 was conducted. Since there were no previous studies in the case of San Gregorio Atlapulco, sampling was conducted in January 2013 in 17 stations distributed throughout the area with a trawl net of 54 μm mesh size and a van Dorn bottle. The samples were preserved with formalin 4 % and 1 % lugol respectively, obtaining a total of 34 samples. A list of 370 species of microalgae were obtained for all the Natural Protected Area from which 36% belong to Chlorophytes; 24 % Euglenophytes; 24 % Diatoms; 12 % belong Cianoprocariotas, 3 % Dinoflagellates, and 1 % Cromofitas, 27 new records for San Gregorio Atlapulco. Among the species recorded, Microcystis aeruginosa and Peridinium willei produce toxic algal blooms, therefore it is necessary to monitor these species and ecosystems to prevent its potential harmful effects, besides continuing ficofloristics studies of the region.
