For the past twenty years, the Laramie County Conservation District
has offered low-cost seedling trees and shrubs, technical
assistance and information to Laramie County citizens in an
effort to encourage the establishment of conservation tree
plantings such as shelterbelts, field or livestock windbreaks,
living snow fences and/or wildlife habitat areas.

Planning a Windbreak
The Conservation District provides free technical
assistance to design a windbreak for your
property. In addition, the district
provides consultations as requested to
determine tree health concerns for Laramie
County residents. For windbreak design
assistance, call Shaun Kirkwood at 772-2600, or
e-mail Kirkwood@lccdnet.org
to schedule an appointment.
If
you want to plan your own windbreak, below are some general
tips to follow:
Tips
On Planting Tree Rows
An average planting by the Conservation District
consists of at least three rows to achieve good wind protection.
A typical planting consists of shrubs or shorter trees comprising
the outer rows, while evergreens (the foundation of the windbreak)
should make up at least one inside row. Your tallest
trees should be in the inside row(s.)
You should not make all your tree rows the same species (i.e.
three rows of juniper.) This will help protect your windbreak
in the event of a disease or insect destroying all of one species.
Planting different types of trees in the same row can create
gaps and reduce windbreak effectiveness.
Spacing
Within and Between Rows
The district suggests the following tree spacing
distances to use when planting trees and shrubs in a row.
Windbreak rows should be planted 20 feet apart. Always
leave enough distance between rows and around your windbreak
to allow cultivating equipment passage.
Suggested Tree Spacing:
Shrubs (i.e.,
Caragana, Lilac, Cotoneaster, Buffaloberry, Native Plum, Chokecherry,
Serviceberry) - Plant 3-6 feet apart
Smaller Evergreen Species
(i.e., Rocky Mountain Juniper, Eastern Redcedar) - Plant
6-12 feet apart
Large Evergreen Species
(i.e., pine and spruce) - Plant 10-12 feet apart
Deciduous Trees
(i.e., Bur Oak, Green Ash, Hackberry, Golden
Willow, Siberian Elm, Cottonwood) - Plant 10-14 feet apart
Remember
that the above spacing recommendations are simply guidelines,
depending on how you want to utilize your planting.
For example: for a windbreak, trees will be spaced closer,
whereas trees in a wildlife planting are spaced a little farther apart.
If you have questions, please call the district for further
information.
Checklist
For Preparing Your Planting Site
Proper site preparation is very important for windbreaks.
Plows, disks, or rototillers can be used to achieve necessary
tillage and are available at rental equipment stores and landscape
companies. The district also has a list of contractors
who do site preparation work. Please call 772-2600
to receive a copy of this list. Fallowing the fall before
planting is essential for dry land windbreaks to allow moisture
to accumulate during the winter. Rows should be 8 feet
wide and 6-8 inches deep.
If
You Order Seedling Trees From The District
Your seedlings will be available the last week
in April .
If we are not planting your trees, you will receive a green
postcard in the mail approximately the second week in April
indicating when and where to pick up your trees. Please
note that the card will come to the mailing address you have
provided on your order form, so be sure and provide the district
with your correct mailing address.
Seedlings
come from the nursery packaged in protective wraps or containers
as either bareroot or potted stock.
| Bareroot
Stock- is packaged in plastic wrap in quantities
of 50 per species with a moisture holding medium (usually
sphagnum moss or polymers) to keep the roots moist.
Exposure to air and sunlight for even a brief period of
time can
kill a tree's root system, and eventually the tree. Immediately
upon receiving seedlings, add water to the moss for absorption. |
 |
Potted Stock- as they come from the nursery beds,
they are placed in special
potting soil and encased in individual 2" x 2" x 7" tar
paper pots or Styrofoam blocks of 30. Trees range
in top height from 4 to 10 inches. The soil in the
pots should be thoroughly moistened after you receive
your seedlings. |
 |
For best results, trees should be planted as soon as possible.
If you are unable to plant trees right away, place them in a shady
area out of direct sunlight.
Weed
and Moisture Management
Weed control is an extremely important factor for
tree growth and survival. Weed and vegetative competition
control should be provided for at least five years.
Remember that weeds are better competitors than seedlings
for moisture, nutrients and sunlight. They also provide
fuel for fires and habitat for tree-injuring pests.
Mulch, cultivation and herbicides are three basic methods
for controlling weeds. The district sells polypropylene
fabric mulch in 300 ft. rolls for $110 plus tax. These
materials are also available at local nurseries. Fabric mulch
has also significantly improved the survival of tree plantings.
Fabric mulch allows moisture to pass through to the soil but
minimizes moisture loss through evaporation. Mulch
should be installed after seedlings have been planted.
Pull seedlings through "X" shaped holes (no larger than 6
inches by 6 inches) cut into the fabric ("X" cuts ensure
the fabric will not rub against the seedling stem.)
The edges of the fabric can be secured with a covering of
soil. Wire staples, rocks, etc. can also be used to
hold fabric down in place.
Watering
Irrigation may be needed at planting time and is
often helpful throughout the first several growing seasons.
Generally, the district recommends 10 gallons of water for
every inch in tree diameter. Also, it is recommended
that you cease watering your trees at the end of August to
allow the tree to harden off. Watering beyond this
time can cause die back of new growth from an early
freeze.
Contact
the district at 772-2600 if you would like to have a free drip
irrigation design prepared in the fall or winter prior to
installing your tree planting. The district also
has a list of drip irrigation contractors and parts suppliers
available. Please call the office if you would like
a copy of this list.
Insect
and Disease Control
Examine trees for insect and disease problems during
the growing season while weeding and watering. Insects
and diseases can severely set young trees back. If you
suspect that your trees have insect or disease problems, call
the district for information on identification and treatment.
Detailed Information on Mountain Pine Beetle
Mountain Pine
Beetle (MPB) attacks any pine tree including Scotch or Scots pine, Lodgepole
pine, Ponderosa pine, Limber pine and Austrian pine. Initially, trees are
attacked by MPB when they are under stress from drought, root or trunk damage, soil
compaction, or herbicide damage. Healthier trees will be attacked as the insect
population increases in the area. Beetles first came into Cheyenne inside
firewood from trees that had been infested with MPB, usually from mountain forest
sources.
*Popcorn
like globs of sap or pitch oozing out of entrance holes made by Mountain Pine
Beetle (MPB) in Scotch Pine. MPB came into Cheyenne inside infested firewood.
Adult beetles
emerge from attacked trees in mid-June through mid-September. Mid-August on
average is the peak emergence time for beetles in Ponderosa pine. The adults
fly to green pine trees and chew a hole into the bark. Sometimes the sap oozing
out of the tree "pitches-out" the beetle.
Trees under
drought stress or in poor health may not ooze sap. If the attack is successful,
a beetle pair mates and the female chews a vertical tunnel where up to 75 eggs
are laid. The eggs hatch and the larvae feed horizontally away from the
vertical egg gallery. The feeding of hundreds if not thousands of larvae will
girdle the tree, cutting off the flow of food and water throughout the tree
trunk. MPB adults typically carry spores of blue stain fungus on their bodies.
The blue stain fungus helps weaken the tree by growing in tree cells that
function in food and water transport. The growth of the fungus aids a successful
beetle attack by possibly slowing or stopping the sap flow in the tree.
Heavily
attacked pines will not die immediately. A dying tree can stay green for up to 8
to 12 months after a heavy MPB attack. MPB spends the winter protected under
the bark in larvae stage and sometimes into the adult stage. In the spring, the larvae
begin to feed again. A few adult beetles survive the winter, allowing them to
continue to lay eggs in the spring or emerge from the trees and attack other
trees. The larvae enter pupae stage in June and July. Adult beetles emerge from
the pupae stage and chew their way out of the tree and fly to green pines.
Several adult beetles may use the same exit hole. The MPB have one generation
per year.
Spraying
Pine trees that
have a diameter of 5 inches or larger should be sprayed
no later than mid-June
with carbaryl (Sevin® and others,) permethrin (Astro®, Dragnet®, and others,) or bifenthrin (Onyx®) labeled for pine beetles. Thoroughly coat the trunk with the
insecticide formulation. Most of these insecticides should be applied by a
professional spray applicator licensed by the State of Wyoming. A spray
application no later than mid-June should provide protection for one adult
flight period or one growing season. Susceptible pines should only need one
spray application per year no later than mid-June.
Storing or Transporting Firewood
Ideally, pine
tree trunks destined to be firewood should have stood in place for at least one
year after the needles have fallen off of the tree (two years after bark beetle
attack,) or be well seasoned or dry. Otherwise, it should be assumed that any
pine tree wood has a possible life stage of MPB inside under the bark.
Firewood should
be securely covered with one or two layers of 6 mil thick clear plastic tarp
treated with UV inhibitors to make the plastic resistant to sun damage. MPB can
sometimes chew through the plastic, but at least the number of beetles attacking
green pines will be reduced.
vvvvv
Pine trunks
with the bark peeled off can be stored as firewood without being covered.
Transporting
uncovered firewood during the adult beetle flight period (mid-June through
mid-September)
could spread the beetle from the mountain forest to your yard. The
best precaution
is not to transport any wood that could contain Mountain Pine Beetle.
Take all
necessary precautions from spraying your pine tree trunks to carefully
selecting
and storing
your firewood, or next year's firewood may come from your own yard.
Winter
Care
Snow cover is helpful to the young trees.
A snow fence on the windward side of the windbreak the first
year or two will protect plants from desiccation and add soil
moisture.
Protection
from the wind - most
evergreen species require protection from wind, especially
during winter months. Sunlight reflected off snow and
wind can quickly dry unprotected conifer foliage. It
is recommended to install wind protection for evergreen trees
the first three years of establishment or until the trees
are taller than the protectors. The Conservation District
sells the mesh, bi-fold tree protectors for $2.00 each.
Please note that the district has no control over inventories
of these protectors, so be sure to call ahead of time to
check availability. Other items that can be used for wind protection
include wood shakes and bales of straw.
Replanting
Trees
If you need to replace trees in your windbreak,
count your dead trees in September or October each year to
know what species you will need to replant. Customers
are encouraged to place an order early, as species sell out
rapidly. If purchasing trees for replanting through
the district, you still must order the minimum that the district
offers (30 for Potted or 50 for Bareroot.)
The
district DOES NOT
order extras and sells only what is left over in the late
spring from our own plantings. Never allow a windbreak
gap to remain; replant as soon as possible.
The
district encourages ordering extra plants when first establishing
your windbreak. They can be grown in a separate nursery
area for a year or two. This will ensure that the replacement
trees (if needed) will be the same age as the tree and shrubs
in your windbreak.
IF
YOU HAVE ANY QUESTIONS OR CONCERNS ABOUT ANY ASPECT OF YOUR
TREE PLANTING, PLEASE FEEL FREE TO CONTACT OUR OFFICE at (307)
772-2600.
The
district provides this technical assistance FREE to Laramie
