Imagine you have a special tree in your backyard that you really love. It gives you shade, makes oxygen for you, and even has a pretty shape that you enjoy looking at. Well, sometimes people want to cut down trees to make room for buildings or roads or just because they don't like the way the trees look. But if your special tree has a tree preservation order, it means that the people in charge can't just cut it down whenever they want. They have to follow special rules to make sure the tree is safe and healthy. For example, they might need to get permission from special tree experts, or they might need to give you a good reason why the tree needs to be cut down. Basically, the tree preservation order helps protect special trees from getting hurt or killed just because someone wants them gone.
