Abstract
The texture valence of a forest tree species is defined as the percentage of the soil texture chart total area occupied by its habitat texture values. By a simple calculation, the general formula is established for assessing that percentage. Then, the formula is applied to 14 taxa present in the most important Spanish forest stands. As far as the soil texture is concerned, from the obtained results, Pinus canariensis appears as the most estenoic species, and the Mediterranean subspecies of Pinus pinaster shows the widest variation of all the studied species.
Key words: habitat, texture valence, forest soils.
