Nowadays it is relatively easy to get trees from any country in the world. But this, although it is very good since it allows us to have a greater number of species, it also has its negative side if we do not do it correctly. In fact, Trees such as ailanthus were first used as ornamentals, but today they are fighting to eradicate them. Why?
because this tree has been able to adapt too well to the climate of Spain, particularly from the Mediterranean region. It supports drought, and its seeds, which are produced in large numbers, germinate easily. There are people who hate it so much that it is not surprising that when they see one that looks a lot like it, like the toona sinensis, think that it is an ailanthus and look at it with bad eyes, despite the fact that T. sinensis is not invasive at all.
for that, and In order to avoid misunderstandings, in this section we will talk about invasive trees in Spain; not only of those that are included in the Spanish Catalog of Invasive Species, but also of those that have invasive potential.
