Short answer: yes. Long answer: you need to put in a bit more work than "just" buying it up. In the UK, Ireland, and other countries with out of control deer/grazer populations and no large natural predators, this means enclosing the land with deer fencing (allows smaller animals to pass, but not large grazers) and probably doing some initial remedial work (scattering seeds of native species, planting a few native trees, etc) to kind of "get things going". Usually after 5-6 years you can just let nature take over and go with traditional "ignore it" rewilding, once some kind of life is established. After maybe 10 years you can consider removing the fence.
