When the improvement of the woodlot is seriously under consideration,
one of the first propositions is to determine just what purpose the
woodlot will serve in the economy of the farm. Ordinarily a woodlot
will be maintained for the following reasons: 1. To furnish fence
posts; 2. To furnish fuel; 3. As a shelter belt for certain areas
or for the whole farm; 4. As a protection on steep up-lands against
erosion; 5. As a means of regeneration of worn out land; 6. As an
investment pure and simple, without regard to immediate returns; 7.
For the aesthetic value. Any combination of these reasons may prevail
for the maintenance of a woodlot; however, each one of them will be
discussed in its turn as separate propositions.
1. Probably one of the chief reasons for maintaining the woodlot on
farms in Kentucky from the purely utilitarian standpoint will be to
obtain fence posts. These are a commodity on the farm which cannot be
dispensed with and for which the demand is staple. Concrete may and
will at some future date, supersede wood as fence posts, especially
in rich easily accessible agricultural regions where farming is very
profitable and conducted as a business, but it will do this only
slowly in remote regions, and at the present time concrete posts are
not extensively used in any locality. A woodlot can then be reasonably
maintained for the production of fence posts. Ordinarily the posts
are largely consumed on the home farm, since they are more valuable
to the producer at this point than if he should sell them; however,
if there is a surplus, a market for this will not be lacking and the
price obtained will more than justify the cost of the establishment of
the woodlot and its maintenance up to the time of harvesting the crop.
In considering the species which lend themselves most readily to the
production of this class of products in Kentucky, undoubtedly, black
locust (Robinia pseudacacia) sometimes locally called yellow locust,
lends itself most readily to this purpose. It is indigenous to the
State, grows fairly rapidly and lasts a long time in contact with the
soil, three prime requisites of any species which is to be used in the
growing of this class of material. Other species which may be used are
catalpa (Catalpa speciosa), walnut, osage orange, chestnut and juniper
(also known locally as cedar or red cedar).
2. As a general proposition, it appears that the maintenance of a
woodlot for the growing of fuel, so far as Kentucky is concerned,
is not an important consideration. So far as my observation goes
throughout the State――even in the rural districts――coal is the general
fuel in use on account of the abundance of supply and is in a large
number of ways cheaper and preferable to wood as a fuel. On this
account the woodlot will supply only a very small amount of fuel and
consideration of this matter is not important. If it does happen that a
supply of fuel wood is desirable or necessary on the farm, undoubtedly,
hickory and oak lend themselves most readily for this purpose. Any
species of hickory grows fairly rapidly, and certain species of oak, as
for instance red oak, makes a reasonably rapid growth. A woodlot for
this purpose would be managed as a sprout forest.
3. The removal of forests and wooded areas of Kentucky has undoubtedly
resulted in certain climatic changes. These are principally to be
noticed in the prevalence of high winds which formerly did not exist,
and such winds have a marked effect on certain farm activities, as for
instance the handling of an orchard or the handling of stock. A shelter
belt, therefore, offers protection to the farm house and surrounding
buildings. To be of use, the shelter belt or wind break must be in the
direction of the prevailing winds. Further, since in all probability
a shelter belt is of most use and is most desirable in the winter
time, the component species in the shelter belt should be, to a large
extent, evergreens, so that the effectiveness may be as great in winter
as in summer. In connection with an orchard, a shelter belt or wind
break, undoubtedly, protects against cold and destructive currents of
air which injure the orchard in various ways either by injuring the
blossoms of the fruit, or at a later period, by injuring the fruit,
which is blown from the trees by the wind and left in bad condition for
shipping.
The species then which should compose a shelter belt should, as far as
possible, have these characteristics. They should grow fast to furnish
the maximum amount of protection in the shortest space of time, and
should have as wide a usefulness as possible. So far as the majority
of instances are concerned, the shelter belt might have two objects.
The production of useful material for the farm as fence posts as well
as a wind break. In this case, it would be well to plant black locust
in conjunction with some evergreens, as white pine or Norway spruce,
hemlock or yellow pine. The number of evergreens which may be utilized
for this purpose in Kentucky are limited, but the number of hardwoods
which lend themselves to this purpose is very great, as for instance,
the hickories, ashes, black locust, poplars, tulip poplar, osage orange
and others. Beech also makes a good tree for the composition of a
shelter belt.

4. As a protection on a steep up-lands against erosion, the chief thing
is to establish a forest cover. The composition of the stand is more or
less immaterial although it is always desirable that the most readily
marketable species shall be used so that the woodlands in addition to
performing their protective function may also supply an actual revenue.
Therefore, as far as possible, the trees to be used should be the
ashes, oak, chestnut, hickories, maples and other species, whose value
in the lumber market is standard. The chief feature in regard to this
protective woodland is that the forest cover shall remain unbroken.
5. As a means of regeneration of worn out land, especially hillsides,
which are liable to erosion and do not lend themselves easily to a
scientific rotation of crops, a forest cover is a very important factor
since it furnishes to the soil the essential humus and, when such
species as the black locust or honey locust are planted, it furnishes
the nitrogenous elements to the soil, since the locusts are legumes and
produce on their roots nodules of nitrifying organisms similar to those
found on the roots of alfalfa, cow-peas or soy beans.
6. As a general proposition, the raising of lumber or timber by an
individual is out of the question on account of the length of time
which it takes to grow the better grades of this material. Ordinarily,
a tree fifty years old will furnish only the poorest grades of lumber
and usually only small dimension stock. Generally speaking, one hundred
years is not too small a calculation for the length of rotation when
lumber is the aim. In the event that any individual plants trees for
the production of the lumber, such planting is done as an investment
purely and simply since he can not expect to see the crop harvested
within his life time. The only monetary benefit that could possibly
accrue to the owner is from the material which may have to be thinned
out or in the event that he should desire to sell his farm when the
existence of a grove or woodland of healthy young trees would represent
an actual money value to the purchaser. In case planting for this
reason is made, the trees should be those which are the most valuable
lumber producing species, as for instance, the oaks, the ashes,
hickory, sweet gum, tulip poplar, white and yellow pines, basswood and
a few others.
7. It may be that in connection with the farm the presence of a
grove of trees thereon will represent a value from the aesthetic and
science standpoint where the beauty of the landscape is a matter of
consideration to the owner of the land, or to any one who might desire
to purchase it. In this event the kind of tree is not so important as
the actual presence of trees of some kind. The general effect is the
main consideration, without regard to the individual features which
compose this effect.
