Hi Katie, thank you so much for your reply. I believe the client’s request is related to the fact horses are more likely to eat decidous trees than evergreen ones. I didn’t realise the wind break effect could be necessary either, at least, not for horses. As for the sun, the site is in north est of Italy, so sunny days are not such a problem during winter time (and in june as well, like this year!).
Again, thanks!
Elena
