My understanding is that _forest_ and woodland habitats are usually slightly 
_warmer_ than the areas outside, and that the temperatures are more _stable_ 
due 
to the wind_breaking effect of the trees, and the canopy traps the air below 
which warms up. That's why balloonists like to use forests to gain lift.

What you state is true of isolated trees, but until man came along trees tended 
 
to grow in forests, I believe.
