H. B. de  aGiant Anteater (Myrmecophaga tridactyla) population survey in Emas National Park, Brazilba proposed monitoring program.  c2006  aThe population density of giant anteaters (Myrmecophaga tridactyla) at Emas Nacional Park in central Brasil was estimated to determine the most suitable method to monitor this population. The data obtained is expected to underpin a more thorough evaluation of the population´s recovery rate following a fire in 1994, and factors possibly affecting its numbers significantly. Population estimates were based on: 1)linear terrestrial transect surveys (distance method). A preliminary giant anteater population-monitoring proposal was outlined based on aerial count data. A power analysis indicated that, to achieve a &gt 90% probability of detecting a 5% annual, population decline, a monitoring program would have to be established using five transects repeated five times a year for 18 years, four times a year for 17 years, or three times a year for 21 years. Terrestrial transect surveys seem more apopriate for more acurrate estimates, although aerial surveys may be the best option in most cases.  amonitoring  aEmas National Park  aGiant Anteater (Myrmecophaga tridactyla)  aMonitoramento  aParque Nacional das Emas  aTamanduá- bandeira1 aTOMAS, W.
