Selecting the right Trees
One good place to find baby deciduous trees is under a conifer plantation, shortly before it is felled. Here the conifers have already been thinned, allowing a mass of baby trees to grow.
Please note that, trees will not survive this procedure if it is the growing season. A good guideline to follow is tree collecting should be done between the Acorns and the Daffodils when their are no leaves, or during the rainy season if you're in the tropics.
Just in case the forestry company decides to turn the site back into a deciduous woodland, I have to be very careful not to decimate toe deciduous tree population, so I have to choose the trees I'm going to take very carefully & only take the smaller trees (but not leggy specimens, which are struggling) or if they are growing right by a foot path, where they will not be allowed to grow.
The trick is to cut a circle around the tree, with a spade and then gently lift the young tree out. In the picture, I am digging up a Birch tree, which has no real tap root, however with Oak or Hawthorn this method is very good as it dose not damage the taproot. Be careful, when digging up a tree with a tap root, not to dig under the tree as this will damage the taproot. The lateral roots don't mind being trimmed by the spade, but the taproot is the most 
important root. Once a circle is cut around the tree, the tap root should be able to be gently lifted out.

It dose make things more fun and allot quicker if you have some help, also it is good to keep a ball of soil around the root (root ball).
It is very important to cover up the roots with some damp plastic and best to transport and plant them in their new location as soon as possible.

Trees need to be a little bit higher than the vegetation they are to be planted in. These trees are going to be planted in a clump of Rose Bay willow Herb, which is why they are so big, But normally 1/2 meters is enough to penetrate through grass or bramble.
