| description |
Effi ciency of conservation units defi ned in Iberá Natural Reserve (Argentina) in protecting reptile’s diversity. Owing to accelerated
biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR)
includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and signifi cant populations
of threatened species. In order to implement its conservation, late last century, fi ve Units of Conservation (UC) were defi ned and prioritized due to
infrastructure and park-rangers, although poorly selected by explicit criteria. We defi ned priority areas for conservation (APCs) using the distribution
patterns of reptiles in the INR, in order to evaluate the effi ciency of the fi ve UC located within its boundaries and detect other possible areas to be
considered in conservation eff orts. The INR was divided into 28 quadrat-cells of 0.25° latitude-longitude and through fi eld samplings and revision
of collections we obtained 1482 records of 71 species of reptiles, computed their presence / absence in the cells. We estimated species richness and
Combined Biodiversity Index (including rarity and degree of threat) by cell. APCs were defi ned by an exact search (complementarity index), obtaining
the minimum set of areas containing higher values of the indexes used, which is called “maximum effi ciency”. The minimum area required to represent
all species was ten cells (36%) and only two of them includes current UC. Add eight cells are needed to fi ll conservation gaps of reptiles, particularly in
the north of the INR. About 20 threatened or poorly known species, 12 (60%) were not recorded in cells with UC. We proposed additional UC in order
to protect all reptiles and include threatened species. |
