    Architectural construction is a creative work, which means that in addition to new designs, it is necessary to find new natural materials, which adapt to current needs, and at the same time, minimize the negative impact on nature. This work contributes to this end, as it describes the process that has been carried out to prepare a catalog of the properties of timber species found in the province of Morona Santiago, Ecuador and that by 2020, were not yet registered in the Ministry of the Environment. Twenty-six timber species that were found in the Morona Santiago province were collected, from these, six were selected, with the aim of studying the moisture content, resistance to static bending, compression parallel and perpendicular to the fiber and density. anhydrous. The determination of the different properties such as specimen dimensions, machine speed and furnace temperature, was based on the methods of: - The Standard of the Institute of Standardization of Chile (INN) 176/1, - The Standard Instituto de Normalización de Chile (INN) 176/2 of the year 1984, - American Society for Testing and Materials (ASTM) D143-94 Wood Standard. Based on the study and comparison of these standards, a laboratory work was carried out with the six prioritized timber species, based on this work, the analysis of their physical and mechanical properties is exhibited in this document. they detail the possible uses. In summary, it can be affirmed that those with medium density and resistance can be used for the construction area in the elaboration of structural elements, in the manufacture of furniture and cabinets, of moldings for the exterior, also for floors, for decking, likewise, in the manufacture of doors and windows. On the other hand, those of lower density can be used to make decorative elements and also for formwork
