You want to be as far away from a tornado as possible. Trees will not protect you. A tornado can carry trees, cars, buses, semi trucks, whatever several miles and drop it on your house - or where your house used to be!!! There is no protection from tornadoes except for good luck.

If no underground shelter is available, like when in the woods, a ravine of some sort is the best shelter.

I've seen a two tornadoes in my life. One touched down - exploded a couple of farm buildings - and one didn't. Have seen the aftermath of several. Awsome...just awsome!

Wouldn't fathom a guess concerning forest fire.......
 
Depends on the forest type and aspect the house is placed if you are on say a hill. Most state forestry services have guidelines for defensible space. If you were in a predominantly pine forest, I would follow the guidelines. If you are in a mixed hardwood or hardwood pine, I wouldn't be as aggressive.

A great site from the National Interagency Fire Center in Boise.


Tornado? A basement, root cellar, or hurricane room is your only chance.

Funny that none of these shelters have inside opening doors? What if you have a tree or mobile home on top of your shelter after the storm passes? If you have a wood saw and a hacksaw in your shelter at least you could hack your way out with an interior opening door.
 
The best hope is to have underground or concrete dome type buildings. Both will stand up to trees falling or thrown fairly well, both will stand up to almost any tornado when properly executed.

A "normal" stick built house can not be expected to stand up to a "direct strike" from any natural disaster, whether it is fire, wind, flood, tornado, earthquake, insects or tree. Distance to the tree line, landscaping with fire resistant plants and trimming, many methods can be used to better the odds in your favor, but they are still odds. The only "sure" way is a totally different design philosophy. There are many earth bermed, underground, bunker, concrete dome, etc. types of designs that are orders of magnitude more survivable. Even an old fashioned log cabin will stand up to more things than a modern quarter million dollar flimsy stick construction home.
