These examples are not suggestions of what to plant if they don’t already grow in your area. They are just examples of how trees can be made use of. If these trees do not grow in your area there may be a tree which can do the same things and does.
If you bring a tree into your area which has not already grown there for a long time it can spread very fast and become a weed. Sometimes, it may grow over people’s farmland and stop them using it. There are other good reasons for using trees from your area. For more information on this, you can look here.
There are lots of things to think about when choosing a type of tree to plant.
It is important to think carefully before cutting down trees if you don’t know how rare they are. This can also apply to trees on this list. They might be endangered.
Some of these trees may have many different names. Not all of these names can be listed for each tree.
Trees or their fruits can be poisonous. You should only do eat or use something from a tree if you are certain that it is safe to do so.
The countries that each tree is found in and the climate and soil it prefers are a rough guide only. A glossary of unusual words in this list can be found here.
