We conducted night-light counts along 124 km of the Parana River and its tributaries. The mean observed density was 0.12 caiman per km surveyed. We counted caiman nests, marsh deer, and capybara groups over 957 km2 of habitats representing 43% of the area to be flooded, by means of aerial survey. The mean estimated density was 0.49 caiman nest/km2, 0.51 deer/km2, and 0.16 capybara groups/km2. Extending these results to the 1280 km2 of floodplains in the area, we estimated 630 caiman nests per year, 650 marsh der, and 200 groups of capybara to occur in the area. We recommend the creation of a protected area to guarantee the survival of the broadsnouted caiman and marsh deer in this region.  aPantanal  aCapivara  aJacaré  aAerial survey  aBroad-snouted caiman  aCapybara  aCenso aereo  aCervo  aDam  aMarsh deer1 aCAMPOS, Z.
