Diagnóstico do levantamento da herpetofauna em estudos de impactos ambientais no Estado do Ceará

Abstract

Environmental licensing is the administrative procedure by which the environmental agency evaluates the possibility of authorization for the location, installation, expansion and operation of enterprises and activities that use environmental resources considered effectively or potentially polluting.one of the projects that evaluate the possible impacts that occur in a given area is called Environmental Impact Study (EIS).the EIAS aims to describe the environmental impacts resulting from the implementation of enterprises. The herpetofauna survey is one of the conditions required in the Environmental Impact Study for the environmental licensing of any project.this work aimed to perform a diagnosis of the herpetofauna survey in EIA in the state of Ceará.the analysis was performed through the SEMACE website, where 30 studies were chosen by the criteria: location, number of species of reptiles and amphibians, sampling effort, methodology and seasonality. It was found that there were 7 methodologies being used in the studies, being active search, pitfall, opportune/occasional encounters/ bibliographic survey, field observations, interviews with residents and others, but they were not always used in combination. The amphibian margin was 26.60% and the reptile margin was 41.44%, as several EIAs presented very low numbers of species surveyed.Therefore, the results of this study can serve as a basis for environmental agencies that are responsible for licensing, as well as for consulting companies, environmental consultants and managers of environmental agencies, to improve their decision-making processes in the approval or not of EIAs.
