Plant fruitbearing trees during afforestation

It is important to plant fruit bearing trees to be planted during afforestation . But in certain regions where the atmosphere doesnot support such plants it should be avoided at the initial stage. Initially the plants which can survive harsh climate shud be planted . After these plants growup to 4-5 feet then the fruit bearing plants should be planted in between them.This will help the animals/birds living there to survive when that area becomes a jungle.
