ABSTRACT
This papers presents some preliminary result from image processing of LANDSAT/TM imagery over the
Jurué Extractive Reserve, aiming to produce ecologic-economic zoning maps based on the characterization of
natural landscape units (mainly vegetation types). This work is part of a more extensive project, named "Can
Traditional Forest-Dwellers self-manage Conservation Areas? A probing Experiment in the Juruá Extractive
Reserve, Acre, Brazil", currently under development by a multi-disciplinary team of researchers from several
Brazilian and foreign institutions. The final goal of the project is to help local communities of rubber tappers
in monitoring and preserving natural resources within the reserve. Image processing techniques for
characterizing natural landscapes included non-supervised and supervised classification and semi-variogram
textural classifier (STC). Standard classification techniques were found useful for defining different patterns
of human occupation. However, they were less efficient in separating different vegetation communities,
because of spectral heterogeneities. The STC, on the other hand, enhances different forest textures.
