At present, integrated studies about flora and fauna are being carried out in the Biosphere Reserve Sierra del Rosario, Pinar del Río, Cuba; and as a contribution to them, it is offered information about its composition of saurians and the structure of three communities belonging to this faunistic group; the two first were associated to the secundary vegetation, while the third one to an evergreen forest. Visual countings were done in eigth locations during the wich the kind of substratum where every animal as found was taken down. After being achieved the final data by means of the transects method, some ecological evaluations were performed. Thirteen species of lizards were observed, eleven of them belonging to the Polychridae family, one to the Tropiduridae family and one to the Gekkonidae family. Tree and bush trunks as well as the ground were the substratums most traveled. The community which habitat presented a lesser degree of anthropical damage was the one with higher endemism. The species Anolis homolechis, A. alutaceus and A. sagrai were abundant in the secundary vegetation, while A. allogus was abundant in the evergreen forest. The higher faunistic similarity was observed in communities associated to similar vegetal formations. Species riches, diversity, equitativity and concentration of species showed higher values in communities which lived in a secundary vegetation.
