Threats
The reasons for this species's
historical rarity are unknown because, until recently, large areas of
potentially suitable habitat remained. It is now severely threatened by
the massive destruction of the Brazilian Cerrado. The combined effects of
grazing, invasive grasses, annual burning and conversion to agriculture
for Eucalyptus plantations, soybeans and pastures for exportable
crops, encouraged by government land reform4,6, had
heavily or moderately altered two thirds of the Cerrado region by 19933.
Most of this destruction has occurred since 19502.
