The following research determines the influence of habitat fragmentation on the population density of the Cattleya rex O'Brien, for the loss of forest; through the analysis of satellite photographs with GIS applications; in the year 2000, it was deduced that the fragmented area represented 45%, increasing until 2014, to 60%. The sampling area for this investigation was 3 ha, whose elevation is between 1390 and 1460 masl; the density of phorophytes was calculated, in which the Cattleya rex O'Brien plants were quantified; whose results yielded a statistical average of 4 plants of Cattleya rex O'Brien per phorophyte and the statistical average of phorophytes reached 17 phorophytes per ha. and an average density of 68 Cattleya rex O'Brien per ha .; Likewise, it was estimated that for the year 2000, the loss amounted to 289,616 Cattleya rex O'Brien plants, and for 2014 this loss was calculated in 880,614 Cattleya rex O'Brien plants and according to the rate of increase of the last 10 years, the loss to the year 2016, was estimated to border a figure of 885272 Cattleya rex O'Brien plants due to habitat fragmentation that exceeded 60% of the forests of the sub basin; finally thematic maps were elaborated according to the requirements of the study and the area of the sub basin was calculated in 21850.9 ha, with a perimeter of 90.1 km.
