Help! New Server created - Trees and boulders don't respawn

Just started playing again, haven’t played since legacy. Started up a new server and trees and boulders are not re-spawning. Obviously this causes a problem with building, refining etc… Does anyone know what is causing this? Is this working as intended? Is there anyway to fix this? So far server population is low so it’s not too much of a problem but it will become a problem eventually.
