Tree List Manager – Introduction


2.1 Introduction to Tree List Manager Ver. 2.0
OntarioTLM is the data translator component of FVS . The TLM tutorial will
help you understand the mechanics of translating an input data file into a
format that the model can use. Users who want a better understanding of
OntarioTLM should attend a FVS training course. TLM uses the same
editing features as most
popular spreadsheet
Data Inputs packages (e.g., Excel).

OntarioYou should be familiar used by FVS—the growth model at the heart of FVS . The minimum
with editing spreadsheets information needed in an FVS treelist is plot ID, tree ID, tree count (if
before using TLM. sampling with a prism), species, and DBH. TLM will generate estimates of
height, live crown ratio and crown width if those data are not provided as
part of the tree list.
Input files must be text files (i.e., non-binary) with one record of data per
tree, and columns must be either fixed width or delimited by spaces or
commas.
It is also possible (but time-consuming) to enter data directly into the TLM
data grid to create a treelist.
Data Translation
The translation process involves:
• identifying the characteristics of the input data (plot type and shape,
species codes, and programs (FVS / SVS) to which the data will be

(one record per tree) and • importing the input data file
translates them into a
treelist. • specifying how the input file columns are delimited, and identifying
columns and their units
• naming the treelist output file that will be exported, and determining
whether FVS and/or SVS files will be created, and
• correcting errors in the data
TLM uses four forms to input information about a translation:
The Project Setup form appears when TLM is opened, and is used to identify
the characteristics of the input data.
The Plot Info and Tree Data forms appear on the TLM – Tree List Manager
window. The Plot Info form requests Plot Identification information, how the

plots are grouped, and either plot area or basal area factor. The Tree Data
form identifies the information collected on each tree in the sample,
including such information as Plot Id., Tree Id., Species, Origin, Status, DBH,
Quality, Height, etc.. and asks you to identify the name and location of input
source files.
The Export Setup form allows you to name the file and direct whether files
Ontariowill be created for export to SVS and / or FVS .
By filling out these forms you create a list of commands that tell TLM how to
translate the input data file into a treelist.

Lesson 1: Preparing Data, Data File Input
Lesson Objective
This lesson describes how to identify input data characteristics and then
import the data file.
Overview of Steps
1. Start TLM.
2. Complete the Project Setup form.
3. Create the Tree List file by:
• selecting the source file type, directory and name
• ensuring mandatory field names are linked to correct source field names
on the Tree Data form
• completing the remaining fields on the Plot Info form
Step 1: Start TLM
You can access TLM in two ways:
Ontario• through the TLM folder in the FVS folder on your computer
(double-click on the TLM.exe icon)
Ontario• through the Start menu (Start 4All Programs 4FVS 4TLM).

Step 2: Complete the Project Setup Form
The Project Setup form appears as soon as you click the application file
(“TLM.exe”) icon and start up TLM. The Project Setup form allows you to
confirm the type of plot from which data is derived, whether alpha or
numeric species codes are used, and whether you want SVS to display the
tree list in a circular, square or rectangular format. After inputting your
intention to have data exported to FVS and / or SVS, you are given the
option of developing basic or full set tree list formats for the creation of FVS
or SVS files. The default tree list input is basic.

Many OPC records use
Alpha species codes.
Numeric is the default in
TLM, so double check the
type of input under
Species Codes before
clicking “OK” to save
time later.

For this exercise, select Prism Plot using DBH as the Plot Type, Alpha as the
format for the Species Codes, Export Data to FVS and Export Data to SVS,
choose Basic tree list formats for both, and indicate that SVS is to display the
tree list in Circular format.
Click OK.
Step 3: Create the Tree List File
The TLM – Tree List Manager window will now come to the front.
There are two ways to create tree list files with TLM – by either direct data
entry, or by importing data from other Microsoft applications. For this
exercise, data will be imported from a ft Excel spreadsheet.

Data Entry, Importing a File
TLM has been developed in a spreadsheet format. It is based on rows and
columns. The columns have pre-assigned field names that are required for
OntarioSVS and FVS .
There are two spreadsheets to complete, one for plot level information and
one for tree level data. The form below illustrates the information to
complete when data is collected from prism plots, and basic data is to be
exported to FVS and SVS. The top portion of the form is structured to hold
plot level (either fixed-area or prism) information.
The * below or beside the field name indicates that information is
required for each of these columns.
Import Data to TLM.
