      Biosphere Reserve Information



  General Description   Yabotí is located in the Brazilian rainforest biogeographical region. The biosphere reserve constitutes a rich subtropical forest ecosystem, with a high diversity of species in the herbaceous, underwood and tree layers. It also contains riparian (gallery) forests and numerous watercourses. The fauna is diverse, including many endangered, and rare species of reptiles, birds and mammals, particularly those of economic importance rendered rare through illegal trafficking. It is an important area for rehabilitating subtropical forests (after logging). The Province of Misiones has 790,325 inhabitants(1994), engaged in agriculture (‘mate’, tea, fruit) and forestry. Some 3,500 Guaraní indigenous people live in the area in precarious conditions and with very limited possibilities to develop a sustainable economy in the endangered rainforests due to increasing logging activities. The main objective of the biosphere reserve is the rational development of the forest resources by selective cutting in the transition area by local landowners, closely controlled by the Ministry of Ecology and Natural Resources. A tax levied on the value of the extracted wood, goes into the Provincial Forest Fund, which in turn invests in the biosphere reserve. The amount of wood to cut is decided by the landowners themselves in accordance with agreed standards. This taxation system functions to the benefit of both partners. The National University of Misiones also organizes graduate and postgraduate training in forestry and biology at a station within the Guaraní Experimental Reserve.
