Included here are the Canaries, a group of twelve volcanic islands situated in the eastern Atlantic. Among the largest from west to east are La Palma, Tenerife, Gran Canaria, Fuerteventura, and Lanzarote.
Canarian Erica arborea Heath
At its upper limit the xerophytic zones gives way to a forest scrub zone of Erica arborea (tree heath) and Juniper phoenicea. Other common components are Myrica faya and the endemic Ilex canariensis (Aquifoliaceae). In some of the more exposed areas shrubs of Erica may be no more than 1 m high, but more typically it forms a dense forest scrub up to 12 m high. Other endemic species in this zone include tall shrubs of Teline stenopetala (Fabaceae).
