Well, given the location it is quite easy to find more info on the tortoises:
The local testudo graeca is listed as a vulnerable species by the IUCN.
So be happy that your land is inhabited by this fascinating endangered species!
Remember that the distinction between "useful" and "pest" is doomed to fail because the codependencies of species form a very intricate net, and with extracting one species that we consider "pest" we could endanger the balance of the whole system. Not to mention that one species may act both to our advantage and to our disadvantage depending on their lifecycle and other factors...
When a species becomes harmful it usually means that something has thrown the balance off, e.g. reduction of a predator, monoculture, introduction of non-native species etc.
I would suggest you do some reading on the habits of tortoises and maybe create a little habitat on your acreage for them? Good luck!
