Person who asked about wood-burning stoves and fires. Most campsites these days ban open fires, but most permit barbecues - I've never had to argue the point but if I did I'd argue that a stove should be regarded in the same way as a barbecue. But as with everything, use discretion and common sense. So don't use it in a tinder-dry forest in mid-august (but I'd be cautious about using any kind of stove in these conditions).
On stoves/barbecues in camp sites:
The point is going to be whether the grass gets damaged or not. Previous visitors may have left patches of dead grass despite making assurances that their stove was OK, so arguing the point may not work. Barbeques generally means proper ones, and doesn't include disposable ones that may be used on the ground or just a couple of bricks.
On wild camping:
When I was in the US, fire risk meant everything except gas was banned over large areas (on a national forest area basis), and is a couple of cases whole areas including minor roads were closed off. In between bans not starting until just after we left or ending just after we got left we only had a couple of no stove days.
Having watched UK TV fire coverage, and ridden through burned off areas in France & Spain, I think you would have to work on the basis that campfires, woodburning stoves, and possibly other stoves could get banned in any mediterranean area during the July/August/September period. As a foreign visitor you would be unlikely to know about the bans in advance, and possibly not after arrival either, and that the likely reaction to being caught breaching a ban would be confiscation.
