Organes and lemons

Curious question, 😶‍🌫️ There are so many orange and lemon trees on pavements etc (not on private property) in Cyprus. Are people allowed to pick the fruits from them? Do people actually pick the fruits from them? For the most part, i just see the trees overflowed by oranges/lemons and some even drop and are stomped on the floor. I did see a couple of foreign workers pick a few oranges from a tree but I'm wondering if it's even allowed. 🍋🍊
