Ceja de la Montaņa

The Ceja de la Montaņa or "eyebrow of the mountain" is essentially a
transition zone between the eastern lowland forests or Selva Alta and
the highlands of the Andes [1800-3600 m]. The overall structure is much
like "elfin forest" with small trees, shrubs, arborescent ferns, and abundant
epiphytes. In Peru, the formations are almost in constant fog as the clouds
rise from the lowlands each day. As one would expect, the formation is
made up of representatives from upland and lowland plant families. These
communities typically contain many endemics.
