Timber - one of the cornerstones of many a great nation. The stuff Lord Nelson's fleet was made of as they bravely fought off invaders, and the stuff that is quite possibly holding the roof over your head. If you want good wood, you will have to fell a good tree. Remember they suck up an awful lot of climate-changing CO2 too, so prepare to plant as you prepare to fell.
A FEW COMMON MISTAKES...
NOT KNOWING YOUR TREE
You don't want to be felling hazel for Lord Nelson's warships when he wants oak, so identify your tree before you start to chop.
DOING IT YOURSELF
If in doubt seek professional advice. And don't hire a beaver, they are most unreliable.
DOING IT FOR FUN
Trees are big and often unpredictable. Trees should not be cut down willy-nilly. Unless you are planning to do it for the greater good (fuel, sunlight, housing) leave the tree be. And remember, you've got another to plant.
IGNORING THE LAW
Even if it's in your back garden, it may be covered by a tree preservation order. Not in a garden? You might need a felling licence. A quick chat with your local authority should help. Better that than a hefty fine.
