Abstract


Insurance and efficiency to monitoring and the use of interacting methods for an accurate diagnosis of the vegetation, mainly those from tropical regions, are essentials to contribute to future development management actions. Remote sensing, biological traits associating structural and biochemical data will permit evaluate the behavioral picture of a dominant specie in vegetation that cover great areas. This study aimed to identify the leaf spectral signature features and structural traits related to dominant specie and photosynthesis implications, relating it with environmental stress consequences and discussing critically monitoring using remote sensing methods. Multispectral analysis and hyperspectral spectroradiometer “FieldSpec Handheld” by Analytical Spectral Devices (ASD) from georeferenced points were made. Perceptible differences were detected for mean values of chlorophyll a and b from field data. The use of Hyperion hyperspectral image showed potential to infer the condition of vegetation regeneration analyzed and different intensities of chlorophyll

Keywords
