Abstract

LARREA-ALCAZAR, Daniel M. et al. Uneven representation of biogeographical regions in Bolivia's protected areas and indigenous territories. Ecología en Bolivia [online]. 2016, vol.51, n.2, pp. 141-156. ISSN 2075-5023.

In this study, we evaluated the representation of biogeographical units in national (NPA) and subnational (SPA) protected areas, as well as in officially recognized indigenous territories (IT) of Bolivia. We compiled available cartographic information on Bolivia's NPA, SPA and IT, and compared it with suggested proposal and hierarchization of biogeographic units (regions, provinces, and sectors). For each biogeographic unit, we calculated the representation target under the following three criteria: 1) the 17% target proposed by the Aichi targets of the CBD (Convention on Biological Diversity), b) the representation target expected by the cover of each biogeographic unit in relation to Bolivia's total surface, and c) the expected representation target calculated for each biogeographic unit based on the relationship area - expected representation. We detected a marked under-representation of the Tropical Andean and Brasilian-Paranaense regions in the NPA, whereas the Chaco Region is was notoriously over-represented. For the case of biogeographic provinces and sectors, we detected a general tendency towards under-representation in the NPA, SPA and IT. Our results suggest cautiousness in the use and interpretation of the 17% target recommended by the Aichi targets of the CDB. The results also highlight the potential importance of the SPA and the IT in the vegetation representation in Bolivia, the latter two being examples of "other efficient conservation measures based on areas" (OEABCM); however, we suggest cautiousness on the role of IT in the highlands.
