Maybe it depends, my experience was in the South of Portugal where you get a subsidy to plant olive trees (as an example). They get the big terraforming machines out and basically destroy complete hillsides and then plant the trees protected by 30cm high plastic tubes.
The only care I saw was done by a few farmers that would replant and generally remove the vegetation around them which is hard and noisy work with petrol bushcutters.
I also know someone whose plantation was burned down and he got a fine and had to replant because he forgot to notify the authorities.
These were the exceptions that stood out. There are thousands of hectares of destroyed and abandoned by the fraudulent ones. You can even see it from Google Earth.
