The island of Tenerife has a remarkable ecological diversity in spite of its small surface area, which is a consequence of the special environmental conditions on the island, where its distinct orography modifies the general climatic conditions at a local level, producing a significant variety of microclimates. This diversity of natural microclimates and, therefore, habitats, means that a rich and diverse flora (1400 species of plants). Before the arrival of the aborigines, the Canary Islands and especially the island of Tenerife, were inhabited by endemic animals now mostly extinct. These specimens reached larger than usual sizes, because of a phenomenon called island gigantism.
