Is it permissible to own date palm trees found in forests that are not owned by anyone, and what should we do with trees inherited from ancestors, even though they were not originally theirs?

Forests and palm trees that are not owned by anyone, and that have been cared for, rehabilitated, and pollinated, come into one's possession. The same applies to what ancestors owned by سبق (precedence) to it, based on the hadith: "Whoever precedes to something permissible, it is his." And what you have inherited of palm trees from your fathers and grandfathers is a legitimate inheritance that may be owned according to the legal division of inheritance.
