Species identification and their market value and price evolution since the colonization time of theremnants of the Brazilian Semi-Evergreen Forest (Floresta Estacional Decidual do Rio Uruguai) forpotential timber production was assessed through 41 questionnaires, applied to timbermen and settlers fromthe surrounding region. The diversity of species for timber production commonly known by the peoplereached 63. From the 15 predominant species is relevant to mention Apuleia leiocarpa, Parapiptadeniarigida, Balfourodendron riedelianum, Nectandra megapotamica, Patagonula americana, Luehea divaricata,Cedrela fissilis, Ocotea diospyrifolia, Holocalyx balansae, Myrocarpus frondosus, Cabralea canjerana andPeltophorum dubium. The species with the highest commercial value were: Cordia trichotoma, Cedrelafissilis, Myrocarpus frondosus and Balfourodendron riedelianum. Data from the interviews suggest thatseveral species from the Lauraceae family and Schefflera morototoni, Aralia warmingiana, Machaeriumstipitatum, Chrysophyllum marginatum had an increment in use and commercial value during the last 15years. Changing in the commercial value of a species was pointed out as due not only to the timber qualitybut also to the amount of the timber availability. Overall, it was detected that the species values changedacross time and that the timber industry found several ways to adapt to the demands of forest products.
