These are trees of the variety Niedda, i mentioned it in other topics.
Trees of this size are quite common here, mostly of this variety.
Unfortunately are abandoned, and some are damaged by fire and cattle, but are very productive.
To pick fruit isn't difficult due to the height, branches touch the ground.
The harvest:
In this field i found two great other varieties that there were no trees in my village, one white, that i don't know the name, and another called Murra (=grizzled in sardinian), because it's neither black or white, that i was looking for a long time. I'll talk about in august, when ripen fruits.
