HURTADO ULLOA, R.  e  MORAES RAMIREZ, M.. Useful woody plants of the Tucuman-Bolivian forest in SW Santa Cruz, Bolivia. Quebracho (Santiago del Estero) [online]. 2017, vol.25, n.2, pp.101-115. ISSN 0328-0543.

The use of plant resources by rural communities is expressed on the basis of subsistence benefits, commercial agriculture and massive extraction of products among others. The Tucuman-Bolivian forest conforms the biogeographic province of Yungas on the Andean eastern slopes that shows high diversity of species under subtropical climate regime. In Bolivia, it spreads from the Amboró knot in central Bolivia to the south up to Tarija and then continues in Tucumán, Argentina. This study analyzed the species of woody plants that are useful in two communities: Loma Larga and Masicurí (SW Santa Cruz). Their richness, abundance, basal area and use value were evaluated through interviews to 36 local people while vegetation assessment was carried out in six 500 m2 plots per community. There were 39 useful species in Loma Larga and 68 in Masicurí, while Loma longa showed higher abundance and basal area. The potential availability of timberable species in mature forest in terms of richness, density and basal area is high. The categories for fuel use and construction present greater richness, abundance and basal area in both communities; while those for construction and fuel use had greater use value in both communities. The assessment of the species by the people of Loma Larga and Masicurí depends on the number of species present, their major quantity and if they present a larger trunk diameter so there is also a selection of resources that need to take advantage of. Use categories are good predictors of trends to understand the preferences of available forest resources.
