The completion of the Pan-American highway through Darién and the canalisation of the Truandó and lower Atrato Rivers, to make an inter-oceanic fairway, are currently on hold, but could have serious effects on the species if it is to be completed.
The eastern frontier of Tierra Firme also included the east side of the Gulf of Darién or Urabá, the east side of the Atrato and Truando rivers, ending in Cabo Marzo on the Pacific side.
