Northern European forests are pretty damp. Forests in the Mediterranean areas, though, such as Provence, actually reminded me a lot of Colorado west of the Continental Divide. No sagebrush, but lots of scrub oak, evergreens and other flammable brush such as broom. Those areas are normally tinder-dry by mid to late summer, and wildfires are common.
Colorado's conditions are unusual right now due to extremely low winter snowpack and a very dry late winter and spring. They have really severe drought conditions! If current conditions persist, I wouldn't be surprised if they ban all stoves pretty soon.
Here in the Pacific NW, we always expect a ban on campfires by late July or early August, especially on the east slopes of the Cascades. Even last year, one of the wettest on record, the Wenatchee-Okanogan National Forest instituted a ban that included even concrete fireplaces in front-country campgrounds. Any stove users need to be very careful when the forests are tinder dry. In some states, if you set a fire, even accidentally, you are liable for the costs of putting it out!
However, I never have understood why the fire ban is always lifted just before the start of the general hunting season, even if fall rains have not yet started!
