context_page_description: The Napo moist forests is an ecoregion in the western Amazon rainforest of Colombia, Ecuador and Peru.
context_section_description: The ecoregion is in the Neotropical realm, in the tropical and subtropical moist broadleaf forests biome.
  The Napo moist forests terrestrial ecoregion is part of the 367,000 square kilometres (142,000 sq mi) Napo Moist Forests global ecoregion of the northern Amazon basin, which also includes the Ucayali moist forests.
  The heavy but seasonal rainfall, diverse terrain and soil, and barriers formed by large rivers contribute to great diversity of flora and fauna.
  In the past the region has undergone large shifts in average temperature and humidity, with new species invading the region or evolving within the region.
  Large changes in river meanders in the Santa Cecilia region of the northwest of Ecuador may have created barriers that split species into population that then evolved independently.
