Depending on the situation i may remove, leave or even plant thorn trees.
If the area is to be used intensively we will remove
If we can we clear them out a bit and interplant other species that will overgrow them and theyll die off eventually
And in areas that are truly wrecked and will be given up to nature, i will even plant them on purpose. To keep humans and goats away, privide habitat, soil stability, cover and a green backdrop
