Resumo
We live in a current loss of biodiversity crises, elapsed population growth and
uncontrolled use of resources. One of the alternatives to reverse this situation is to
maximize the use of available resources for conservation, mainly because these are
often limited. The spatial prioritization is an important tool for this purpose. In this
paper, the main objective is to identify the priority ecoregions of the Americas for
biodiversity conservation. Six criteria were used in the prioritization: loss of vegetation
cover, endemism, the presence of threatened species, size of ecoregion, presence of
protected areas and economic value. Moreover, was identified the protection status of
each ecoregion, the highest priority group animal, the threat category and the proportion
of Data Deficient species (DD). Ecoregions were found in four categories of priority
(B3-A3). The highest priorities are the small size, especially islands, and ecoregions
located in the Caribbean, Midwest and Southern South America, Mexico and the United
States. About 75% of ecoregions not have protected areas or these are insufficient.
Moreover, nearly half of the ecoregions of the Americas are threatened. The group of
birds was considered the highest priority in most ecoregions. The proportion of Data
Deficient species was lowest in North America and most biologically diverse regions in
the most, especially in the group of amphibians. This paper added a new spatial
prioritization tool, which should be applied in other regions and scales and contribute to
decision makers, who will have the challenge of maximizing the use of available
resources for conservation in detriment of social and economic reality of each country.
