Major part count issue or no

Hello and morning/afternoon/night everyone
Id like to ask a question: is this part count in any way good for a large map? (half of it is fields other is forest etc)

All parts are anchored and a lot are ucollideable (leaves and bushes)

forgot to add, im in the process of removing about 18,000 other parts that are the branches of the bushes which arent visible
