Since 1980 there has been a significant increase in the total area of woodland in the UK with a large part of this increase found on farmland. This guide details some of the key aspects of the planting process that should be addressed before planting begins.
Trees
for woodland planting are normally supplied between 30 and 60 cm in
height at about two years old. Typically these are bought from a nursery
in bundles of 25 or 50 during the winter months when the plant is dormant.
Plants are normally supplied having been previously undercut
or transplanted. Undercutting is a process where the roots
of the seedling are cut at the end of the first year. Transplanting
is similar but where the seedling is replanted in the nursery. Both
systems encourage the production of fibrous roots that reduce planting
losses when the young tree is planted in the new wood.
Most woodland planting is still done by hand utilising a planting spade. This is a robust tool designed to create a "notch" or narrow slot deep into the ground into which the tree roots are placed. The notch is then "heeled" in so that the soil firmly closes around the roots of the young tree. Some mechanical systems now exist that create a slot, although the tree is still placed by hand.
Young
trees are particularly vulnerable to pest damage in the early years
of the woodland. Protection is essential and this can either be through
perimeter fencing or through the protection of individual trees. Generally
it will be more economical to fence an area that exceeds one hectare,
whereas individual protection will be cheaper for smaller blocks.
When
planting it is important to ensure an appropriate spacing between trees.
Recent fashion, supported by a poor grant system has encouraged the
wide spacing of trees at 3 metres to reduce costs. This is false economy.
Widely spaced trees grow outwards and not upwards and take many years
to create a canopy (the first step towards the woodland environment).
They also suffer poor form and additional weed burden. By contrast trees
planted at close spacing form a canopy within a few years and in creating
a woodland environment grow more quickly and with better form. The image
illustrates trees seven years after planting spaced at 2 metres.
Perimeter
fencing providing effective protection from deer, hares and rabbits.
Whilst fencing like this is common around many new woodlands it may
not provide complete protection. Voles can still damage young trees
and later in life squirrels can ruin a new woodland. Effective protection
of the new wood from pest damage may also require habitat management.
Protecting
young trees with treeshelters is a slow task but shelters can provide
advantages over perimeter protection, namely:
Successful
weed control around young trees can dramatically enhance growth rates.
Without control 60cm transplants may be no more than 100cm tall after
five years whereas, with control the same tansplants could have reached
300cm in height. Weed control can be achieved by applying herbicides
or by mulching around the tree (usually with a plastic mat or woodchips)
although mulching is rarely viable on a larger scale.
A
more recent development for establishing new woodland has been through
the use of sowing tree seeds. These are broadcast onto an area and then
lightly incorporated into the soil. High seed rates are used and in
the initial years herbicide can be applied from a crop sprayer. The
advantage of this system is that it treats the trees as a crop and reduces
labour input - although at some point a significant amount of thinning
will be required.
After
planting, additional maintenance will be required for beating up. Beating
up is the process of replacing failed trees so that the planting density
can be maintained. This will occur only for the first two years after
which failures are unlikely. Ride management and maintenace will be
important from the start and a well maintained ride network through
the wood will provide access for management as well as for amenity and
wildlife gain.

Comment: Seems as though in the UK there is much more support for creating habitat and such.
Thanks for the info on this site. It's got some jewels I can use here.
