There are an estimated 8000 (nobody really knows) plant species in Spain, 2000 of which are endemic to the Iberian Peninsula and North Africa .
Potentially, 95% of Spain would be covered in some form of forest. 20-28% of forest cover remains today. 50% of this is pine forest.
Some 105 species of autochthonous trees grow in Spain (nobody agrees on the exact figure). 44 of these are capable of forming true woods. 33 grow in the Canaries
The most common tree in Spain is probably the holm oak ( encina ), estimated in 1995 at 682,881,000 specimens. However, despite these numbers many holm oak woods are made up of immature specimens.
50% of the 2000 plants found in the Canaries are endemic.
