THE KIND OF REGENERATION PLAN NEEDED BY SERIOUS INVESTORSThe secondmost important operation in making money growing trees (timber
sales procedure is first) is regeneration. You get only one shot at it,
and you're stuck with it for at least 20 years. The right plan often creates
an investment with a 12% annual real return (IRR); the wrong one usually
produces a real IRR of less than 6%. We prepared the following plan for
an actual tract in Georgia, and we present it almost in full to demonstrate
many important procedures. We have completed our site evaluation and reforestation plan for your tract
in Land Lot ___, ____ Land District, ______ County, Georgia. The recommended
management plan follows. We tested 480 different scenarios with various cultural treatments, tree
spacings, thinning ages, levels of thinning, and harvest ages. To evaluate
them, we first forecast by computer simulation the volume of timber produced
by each. We then applied current market prices and discounted future values
to the present at the 8% interest rate you chose to arrive at the bare land
values. Bare land value (BLV) is an important criterion for evaluating possible
management options. BLV is the net present value of all future crops assuming
that the practices be repeated indefinitely. Looked at another way, BLV
is a measure of what the land is worth when it is used in a given manner.
The best options are as follows:
NOTE: "H" = herbicidal site-prep, hand planting, no herbaceous release "HR" = herbicidal site-prep, hand planting, with herbaceous release "MB" = mechanical site-prep, bedded, machine planting, no herbaceous release "MBR" = mechanical site-prep, bedded, machine planting, with herbaceous
release Option 6 yields the highest BLV. If first-year seedling survival falls below
95%, however, the reduced stocking level will allow the trees to become
too limby, thus reducing the quality of the sawtimber trees. We recommend
option 8, as it provides a greater margin of safety on seedling survival
and reduces risk to the investment. We estimate the IRR for options 6 and 8 to be 11.92% and 11.67%, respectively.
This small reduction in return on capital is, we believe, a small price
to pay for greater security. Option 8 includes mechanically preparing the site by shearing the residual
vegetation and raking into windrows, bedding the area to be planted, machine
planting of 363 grade-1, second-generation coastal-plain, loblolly seedlings
per acre, and releasing them from herbaceous competition in the spring following
planting ("band spraying" by tractor.) The plan calls for thinning the trees at age 11 by removing those not suitable
for sawtimber plus enough small-diameter trees to reduce basal area to 80
square feet per acre. The residual stand should contain about 200 trees
per acre of the best-quality trees and should be harvested at age 21. Should you engage us to perform the reforestation work according to option
8, we will solicit bids for the work from vendors on our list and Georgia
Forestry Commission lists and submit the bids to you for approval. We will
specify the requirements of the work and supervise the vendor you choose.
We will inspect the prepared acreage and verify all work before you disburse
payment. We will order custom-grown seedlings, have the seedlings stored
in a refrigerated warehouse in Albany, deliver them fresh to the site, have
the vendor apply LiquaGel to the root systems, inspect for proper planting
techniques, and keep a record of the plots we take on the stocking. We will
also certify the average root-collar diameter of a sample of the seedlings.
Finally, we will cruise the planted areas approximately one year later to
report first-year survival. Our fee for supervising the work is 15% of all costs as incurred. A schedule
of estimated costs for each part of the planting operation is shown in the
attached management plan. We recommend that you apply for possible government subsidies to help offset
the cost of reforestation. You should do this by contacting the county ASCS
office. If approved, you will find that the Georgia Forestry Commission
will impose certain restrictions for you to qualify for payment. They may
approve only a limited acreage, insist on a higher number of planted trees
per acre, and specify other practices. If you wish, we will make an economic analysis of any GFC plan, so that
you can decide whether governmental restrictions attached to the subsidy
will reduce the bare land value by more than the payment you will receive.
We will quote you a price for the analysis before doing it. If you want us to proceed with the plan as described in option 8 above,
please sign, date, and return one copy of this letter to us, and keep the
other copy for your records. We will not begin soliciting bids for the work
until cutting operations have concluded and you receive a release from ______
Timber Company. The cutting contract will expire on 31 March 1997. THE VARDAMAN FOREST MANAGEMENT PLAN 28 April 1995 The following Management Plan is for approximately 76 pine plantable acres
in Land Lot ___, ____ Land District, ______ County, Georgia. The dominant soil type is Alapaha loamy sand. Using a soil auger, we verified
this according to SCS description: Typically, the surface layer is black loamy sand about 5 inches thick. The
subsurface layer is loamy sand and extends to a depth of about 28 inches.
It is dark gray in the upper part and gray in the lower part. The subsoil
is sandy clay loam and extends to a depth of 70 inches or more. The upper
part of the subsoil is gray with light yellowish brown mottles, and the
lower part is mottled brownish yellow, red, light gray and strong brown.
Plinthite is below a depth of about 46 inches and makes up 5 to 15 percent
of the lower part of the subsoil. To determine the normal site index, we searched for dominant and codominant
loblolly pines on which to measure their age and total height. As this tract
is dominated by slash pine with loblolly and longleaf as minor components,
relatively few loblolly trees were available to be measured. Also, many
trees exhibit mechanical injury from a windstorm or other event several
years ago. This is seen as a "crook" about 10 to 15 feet below the top of
the tree. While the damage has not reduced the merchantable volume of the
trees, it has affected total tree height. Of the several loblolly trees present, only three qualified for site index
measurement, being dominant or co-dominant in the stand, free of defect
and disease, and not over-crowded. These trees exhibit a site index, base
age 25, of 69.1 feet. Nevertheless, a sample of such small size is not sufficient
to establish site index for the entire tract. As data were lacking to establish site index from the existing stand, we
used data from the USDA Soil Survey for ______ County. First, we estimated
the percent of total area covered by each of the six soil types present.
Then using the site indices listed in the soil survey, we calculated the
average site index for the tract weighted by acreage. By this method, we
estimate the average normal site index, base age 25, for the pine plantable
area to be 66.6 feet. According to a chart prepared by Dr. Lee Allen of the North Carolina State
Forest Nutrition Cooperative, the practice of bedding on the Alapaha and
related soils will yield a weighted average gain in site index of 4.6 feet.
Adding the bedding gain to the estimated normal site index yields a total
of 71.2 feet. Since we recommend using 2nd generation improved seedlings,
we further revised the normal site index up 11% to 79.0 feet.

ECONOMIC ANALYSIS In our economic analysis, we estimated total regeneration costs (shearing,
raking, bedding, seedlings, planting, release and 15% supervision) to be
$281.35 per acre. We also used a real, compound discount rate of 8.0%, chosen
by you, annual property taxes of $2.78 per acre, assumed that no prices
would change and that this series of operations would be repeated every
22 years forever. Stumpage prices were derived from the sealed-bid sale
from this tract on 24 February 1995.

SULFOMETURON+IMAZAPYR Herbaceous Weed Control Prescription for Tractor Application
DuPont and American Cyanamid Sulfometuron 75% ai + Imazapyr 54% ai, 4 ae
lb/gal
Oust + Arsenal Applicators Concentrate
Apply 2 oz Oust + 6 oz Arsenal AC in 5 to 30 gallons of water per acre.
Use a minimum of .25% by volume of a non-ionic surfactant. Drift control
and anti-foaming agents may be added as needed.
Thoroughly clean application and mixing equipment immediately after use.
Prolonged exposure of this product to uncoated steel surfaces may result
in corrosion and failure of the exposed part.
Product can be applied throughout the growing season, but early season
weed control is generally considered best for optimum pine growth.
Herbaceous weed control is most effective when used in conjunction with intensive site preparation which exposes mineral soil and favors an influx of annual grasses and forbs. Imazapyr can stunt growth of pines when applied at the highest label rates. Lower rates tank-mixed with sulfometuron methyl (Oust) are recommended for effective weed control and maximum pine growth.
Resistant species: sicklepod, coffeeweed and tropic croton
SEEDLINGS TO BE USED
Should you engage us to perform the reforestation work, we will use 2nd-generation, genetically-improved, coastal-plain loblolly pine seedlings. The most important characteristic of such seedlings is how crowded they were in the nursery bed and how much this crowding affected development of vigorous roots and shoots. We currently have available seedlings that were grown at 15-20 trees per square foot in the nursery bed ("low density"). Our supplier guarantees a minimum average root collar diameter of 5.0 millimeters, which is sufficient to produce the projected results. We will measure and certify to you a sample of the seedlings showing the actual average root collar diameter. Our supplier will deliver these seedlings to a refrigerated warehouse in Albany, where we will pick up fresh seedlings each day and deliver them to the planting site.
SURVIVAL CONSIDERATIONS
The key to profitable forest management is regulation of competition of all kinds at all times. In addition to controlling competition from herbaceous plants and hardwood species, we must also regulate competition between planted seedlings themselves. If there are too many of these, their growth will be too slow. The ideal way to accomplish this last mission is to obtain, as closely as possible, the right number of living seedlings at the end of the first growing season.
Our analyses with PTAEDA2V+ECONV reveal that there is very little difference in IRR between planting 330 or 363 trees per acre. PTAEDA2V predicts that survival at age eight for these initial planting rates will be 293 and 317, respectively, and other data show that almost all mortality occurs during the first growing season. We recommend 363 initial trees to give you a small margin of safety, but of course, 300 live seedlings at the end of the first growing season will be enough to accomplish the financial results that we have predicted.
We will make every reasonable effort to ensure the best possible care and survival of the seedlings. We cannot, however, assume responsibility for events beyond our control, e.g., fire, drought, or flood, that adversely affect seedling survival.
Please call me if you need further clarification.
