Consequences of the decrease of endemic flora of the World, Ecuador and the Amazon

Abstract

The endemic flora is one that only lives in a certain place, that is to say whose distribution radius is delimited to a place, region or continent, the endemic term can be confused with native, however, the difference is that a native plant can be born in diverse places of the world and an endemic one is born in a single place.

They are vegetal species that populate a territory or a geographic region, considered from the systematic point of view. The flora will be rich or poor depending on whether the geographical region considered has many plant species or a small number of them.

The set of flora is very variable amplitude, according to the point of view from which it is considered.

Ecuador has 10 percent of all plant species on the planet. Of this percentage, the largest amount grows in the Andes mountain range, in the northwestern zone, where it is estimated that there are approximately 10 thousand species. In the Amazon region there is also a high number of plant species, around 8,200, for example, only orchids 2,725 species have been identified. In Galapagos, however, there are about 600 native species and another 250 introduced by man, approximately. Of the twelve key biodiversity zones identified by the naturalist Norman Myers, three are found in continental Ecuador. Climate diversity has given rise to more than 25 thousand tree species.
