Brazilian environmental legislation states that mountain and hill tops are environmental preserves. This hasbeen regulated by the CONAMA 303/2002 resolution, establishing that the top third of all hills or mountains,with a slope higher then 30% and an altitude difference above 50 m should be protected. However,identifying these areas in large landscapes, automatically, poses a challenge, providing that CONAMAs’baseline definition can be easily questioned. Also, several methods for delimiting such areas require somelevel of interference from an operator, leading it vulnerable to different interpretations. Using a previouslytested method that does not require operator interference, environmental preservation areas related tohilltops have been delimited at a scale equivalent to 1:250.000. Approximately 400,000 km2 of the Brazilianterritory is considered preservation area.
