You're going to have to give us some idea of where this is.
If you have land that has been allowed to fend for itself... I really doubt that it only has brambles and stinging nettle.
Property that has reverted to wild is where I prefer to spend my time... And that kind of land is never monoculture.
Suggest giving it more time, and get a plant person to point out the stuff that you are missing.
I'd do it... If you were nearby.
Re the brambles? lots of stuff eats the berries, and the entire plant is medicinal.
The stinging nettles are edible, and, Some people use them to feed the soil.

Your place sounds really nice... Hope that you don't go too nuts trying to make it be something else.
