This work presents a simple classification method to describe and evaluate the Caatinga vegetation, one of the most fascinating biosystems of the Brazilian landscape, which has been intensively explored since colonial times. Associated to remote sensing techniques, this classification will be able to contribute as a method of reference of terrestrial control, facilitating the interpretation of space images in the inventory of vegetative cover, in studies associated with environmental monitoring and management. For a given biome of Caatinga, the Woody Vegetation Biomass Index (WVBI) is the product of the Height Index (HI) by Cover Index (CI) of vegetation. For a condition of maximum preservation the WVBI is equal to 1. By determining of a reference volume the Woody Vegetation Biomass Volume (WVBV) will be able to be estimated.
