By disregarding topography, estimates of home-ranges size underestimate the surface actually occupied by the animal, potentially leading to misinterpretations of the animals' ecological needs. Our results revealed that underestimations range from nearly zero up to 22%, and that the difference between planimetric and topographic estimates of home-ranges sizes produced highly robust models using the average slope as the sole independent factor. Planimetric estimates in areas with an average slope of 16.3° (±0.4) or more, or altitudinal ranges above the 1800 m will incur in errors ≥5%. In these areas, topography should be included in home-range studies.
