Setting

The Peruvian Yungas occur on the eastern slopes and valleys of the Peruvian Andes. They form a transition zone between the Southwest Amazon moist forests and Ucayali moist forests at lower elevations to the east and the Central Andean puna and wet puna at higher elevations to the west.[1]

Climate

The climate in this ecoregion varies from a tropical rainforest climate in the north to a subtropical highland climate in the south. Precipitation ranges from 500 to 2,000 millimeters (19.7 to 78.7 in) per year.[1]

Flora

This ecoregion contains over 3,000 species of plants, including 200 species of orchids. Orchid genera include Epidendrum and Maxillaria. Tree ferns (Cyathea) and bamboo (Chusquea) are common. Below 2,700 metres (8,900 ft), the forest includes species such as cedar (Cedrela), trumpet tree (Tabebuia), and relatives of papaya (Carica). Above 3,500 metres (11,500 ft), there are scrublands and wet rocky thickets with shrubs and land orchids as well as forests of Podocarpus conifers.[1]

gollark: Yes, I'm aware it's better business-wise, and I don't want to support that.
gollark: They could at least support bridging to XMPP or something natively.
gollark: It works for XMPP.
gollark: You could, theoretically, have selfhostable Discord instances with federation.
gollark: Also because it would cost money.
