To determine patterns of colonization of reforestation areas in Porto Trombetas, Pará, we examined species composition, richness, abundance and biological characteristics of amphibian and lizard species. Also I evaluated the effect of vegetation structure and distance to native forests on the community of amphibians in reforested areas. Amphibians and lizards were sampled along eight occasions in four-eight reforestation areas and four areas of native forests through active search and using artificial ponds for amphibian reproduction. Twenty species of amphibians and 20 species of lizards were registered, with 14 species of amphibians and 11 species of lizards in reforestations and 19 species of amphibians and 16 species of lizards in native forests. Among amphibians, Leptodactylus sp., Osteocephalus oophagus e Allobates femoralis were the most abundant species in the two environments. Among lizards, Gonatodes humeralis and Leposoma guianense were the most abundant species in reforestations and native forests, respectively. Amphibians with terrestrial reproduction or which use small temporary ponds to spawn and arboreal lizards were the most abundant groups in the reforested areas. Fossorial and semifossorial amphibians and litter lizards were the main absent groups in the reforested areas, suggesting that the current stage of vegetation succession does not offer appropriate microhabitats for some species. Species richness of amphibians was higher in areas with larger canopy cover. Areas with larger canopy cover had also higher abundance of Leptodactylus sp., A. femoralis and O. oophagus. Only four species of amphibians have used the artificial ponds for spawning and there was no significant relationship between the number of species that used the ponds and the distance to native forest or the canopy cover. Osteocephalus oophagus spawn in ponds most farer and A. femoralis in ponds closer to the native forest. Results show that amphibian and lizard fauna in reforestation areas is a subgroup of the native forest fauna and encompasses forest species which indicate the relative importance of these areas for the conservation of the local fauna.porAcesso AbertoRéptilAnfíbioLagarto (Animal)Colonização animalHabitatConservação animalFloresta Nacional de Saracá-Taquera - PAPorto Trombetas - PAOriximiná - PAAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::ZOOLOGIA APLICADA::CONSERVACAO DAS ESPECIES ANIMAIS
