Hi, ive got the following list of trees that can work fine as wind breaks for my place and climate ( arid tropical).

Sauce ( Salix)
Moringa
Lemon
Álamo
Yuca
Piñón - jetropha
Huaranguillo
Bamboo
Casuarina
Tagasaste
Ficus


Which one do you think its a good option for a edible forest garden that its starting?
I need a pioner specie that grow fast , but it would be nice if it would generate fertility,fix nitrogen, or provide multiple functions.

Which tree would you recommend?

Your lemons must be a lot tougher than ours:
citrus are one of the least wind-tolerant plants in my climate.
My number 1 from your list would be tagasaste-
tough as anything, grows really fast, coppices, stock/bee fodder, and...nitrogen-fixing.

I'd be looking at a multispecies, multi-height planting.

You want a decent depth of windbreak, not just a tall but narrow barrier as is seen with eg lines of poplar.

Wind is most effectively "broken" by being forced to trickle through a filter, rather than being deflected by a barrier. Denser plantings of ever greens tapering upwards to your tallest trees in the middle.

The "Permaculture Handbook" has an excellent section and diagrams on designing these to be effective and multi functional.
