Tree consultants regularly evaluate trees in order to establish tree value. The value is
dependent upon many specific attributes. Some that can affect tree value are species type, size,
location and condition. The effects of the tree on the local environment, natural and cultural history,
position of the tree in the landscape relative to other structures and other landscape plants, and
aesthetic value of the tree will all affect tree value. There are many other attributes that lend value to
The Urban Tree Valuation Program is a guide for estimating the value of a standing tree in a
yard, along a street or in a wooded lot, and for estimating values of trees lost to storms, pests and
humans. This guide will help a tree owner, horticulturist, urban forester or arborist estimate a value for
a tree, made on the basis of several assumptions. This guide is not meant to replace a qualified
appraiser. Select a tree appraiser that is associated with the Council of Tree and Landscape
Appraisers, 1250 I Street, N.W. Suite 504, Washington D.C. 20005.
Every effort has been made to provide the best information available in a usable format. The
tree value estimates which this program calculates should be used for providing the basis for a range
of tree values from the data input. The primary basis for the work is the International Society of
Arboriculture Handbook entitled "Guide for Establishing Values of Trees and Other Plants" (ISA P.O.
Box 71-5, Lincoln Square, Urbana, IL 61801) and the related Extension Folder 445, Agricultural
Extension Service, University of Minnesota, entitled "Shade Tree Evaluation" by Patrick J. Weicherding.
The folder is superseded by Extension Folder CD-FO-0726 (University of Minnesota Room 3, Coffey Hall,
1420 Eckles Ave., St. Paul, MN 55108). These materials are indispensable aids for further information.
We strongly recommend purchasing and using these materials along with this software.
Tree species are valued differently in north, central and south Florida due to climatic differences.
The program will first ask you to choose the area of the state for which you are calculating values and
will place you in the appropriate part of the program.
The user of this program must enter the species name, it's size, condition and location in the
landscape. The tree species ratings included in the program for your convenience were averaged from
the values given them by 26 Florida tree-care professionals in a survey conducted by the authors. The
species ratings should be used as a guide in estimating tree value. When calculating values for trees
with less than about 12' caliper, the replacement cost may be the best estimate of value, since these
smaller trees can be successfully transplanted by an experienced tree mover. This program is to be
used on trees which are generally considered too large to transplant.
HARDWARE AND SOFTWARE REQUIREMENTS
To operate the Urban Tree Valuation software, you will need an IBM PC or compatible with
256 K memory. DOS version 2.1 or higher and an Urban Tree Valuation diskette are required to run
It is advisable to make a backup copy of the Urban Tree Valuation diskette before you proceed
with these instructions. Use a double-side double density diskette for your backup.
To make the backup for a two floppy-drive computer:
1) Insert the DOS disk (2.1 or higher) into Drive A.
2) Boot the disk by turning on the computer.
3) At the A>, remove the DOS disk from Drive A.
4) Insert the Urban Tree Valuation diskette into drive A. Insert a formatted blank
diskette into drive B. Then type: copy a:*.* b: . The computer will copy the
files onto the diskette in Drive B.
After copying is complete, check to see that 7 files are on the new disk. To check the files, switch
At A> type:
At B> type:
This will list the files on the disk in drive B. The files should include: CTREE.DTA, CTREE.IDX,
NTREE.DTA, NTREE.IDX, STREE.DTA, STREE.IDX AND URBTREE.EXE. All following instructions
referring to the Urban Tree Valuation diskette imply use of a backup.
RUNNING URBAN TREE VALUATION
Two floppy drive systems
1) Turn the computer on with DOS (ver. 2.1 or higher) in Drive A.
2)- Insert Urban Tree Valuation in Drive B and type: b:URBTREE .
This will start the program.
Hard drive systems To load the program into the hard drive:
1) Turn computer on. After the system has booted, insert the Urban Tree Valuation
diskette into Drive A.
2) Make an URBTREE subdirectory:
Type: cd\ , then type: md\URBTREE .
3) Copy files from the Urban Tree Valuation diskette into the URBTREE subdirectory:
Copy a:*.* c:\URBTREE
Installation is complete; seven files are now loaded into the hard drive. The program is ready to run
from the hard drive. Remove the Urban Tree Valuation diskette from the A drive and use it as the
Once the program has been loaded into the hard drive, follow the procedure below to start the program
in all subsequent sessions:
1) Turn computer on.
2) After the system has booted, type: CD\URBTREE .
3) Then type: URBTREE .
This will start the program.
PROGRAM SCREENS/SAMPLE RUN
After you scroll through the first three screens by pressing the space bar as indicated on each
screen, the program asks you to choose the part of the state in which values will be calculated for, 1)
north, 2) central or 3) south (Figure 1). Simply type a 1, 2 or 3 and press the key. The main
menu appears on the next screen (Figure 2). Make a choice by pressing the appropriate function

The databases in this program take into account
geographic and climatic conditions which differ
substantially in three regions of Florida. This
program will work best if you choose the correct
region. Select the region in which the trees are

key. Then, follow the instructions on each screen as you move through the program.
The QUICK-CALC procedure enables you to quickly calculate tree value by entering the
following parameters: tree common name (optional), genus, species, trunk diameter, height (optional),
merchantable height (optional), the condition of the tree and a location value. The multiplier is set at
one (1), but can be changed to any number up to 10,000. The program multiplies the calculated tree
value by the value of the multiplier. Foresters. are most likely to utilize this option. Value per unit area
has been set at $27 since this is the current accepted value per square inch of cross-sectional trunk
area, 4 1/2' above the ground. A report can be printed (pressing the
key) containing the
calculated tree value and the parameter values which went into the calculation. The program uses built
in species values; however, you are given the option of changing the values for the current running of
quick calc. Instructions for moving through the program are clearly given on each screen. A detailed
description of each parameter i.e. species, size, condition and location is obtained by selecting
from the main menu. This will help in selecting values for each of the parameters included in the value
Selecting allows you to view and/or change the species rating values for each of the 108
trees included in the species catalog. Additional trees and their associated species rating can be
easily added to the program by following the instructions on the screen. Never change the species
ratings on the original Urban Tree Valuation diskette; always work with a copy.
ENDING THE PROGRAM
Press the key to end a session. The computer beeps and asks:
Are you sure you want to exit the program? (y/n). Pressing the key exits Urban
Tree Valuation to DOS.
