Guiana Shield
In the highlands, mountains, such as Bakhuys Mountains, Van Asch Van Wijck Mountains, Julianatop, are part of the Guiana Shield. The Guiana Shield is one of the regions of highest biodiversity in the world, and has many endemic species. It can be said that the white-faced saki is endemic to the Guianas. The Guianan piculet ("Picumnus minutissimis") is probably endemic to Suriname. It has not been confirmed for neighboring countries.
