Distribution:
It occupies an ample extension, that would include
the palearctic zone, extending through all Europe until the Arctic
Circle by the north and until Asia and Japan by the east, although
in these zones is not very clear if it is the same species or
another. Also appears in northwestern África.In mainland Spain it is
in all provinces, and traditionally three subspecies have been
recorded:
- Buffo buffo buffo; in the western North
third.
- Buffo buffo gredisicola; endemism of the
Sierra of Gredos.
- Buffo buffo spinosus; that it would occupy
the rest of the regions and reaches the greater size of all. At the
moment its separation in three subspecies is not very clear, because
the existing genetic differences among them are not very significant
and it is considered rather that they are only different geographic
races. In Granada it has an area of very ample distribution. Their
main populations are also in Sierra Nevada, being frequent in other
mountainous systems, Tejeda, Almijara, Baza and mountains of the
provincial northeast. Every time it is but rare to find it in
valleys and low zones like the Vega of Granada, the river deep
valley of the Guadiana Menor, the limit with Almeria and certain
zones of the region of Montes, where it undergoes a severe
regression.
