Design Tool for Inventory and Monitoring (DTIM)
Step 1: Introduction
Welcome to the Design Tool for Inventory and Monitoring (DTIM). The DTIM Wizard will guide you step-by-step through the process of selecting the objectives, questions and metrics for your project. Once you have completed this task, your project will be imported into the full DTIM system for further analysis.
As you work through the screens, note that at any time you can go back and change your responses. And if you make your way completely through the wizard and are unhappy with your selections, know that you can cancel this wizard at any time and start the process anew. So, if this is your first time using this wizard, explore the screens with the knowledge that you can change any of your selections.
On the following screens, you will see this icon

Description:
The
National Forest Management Act of 1976 (NFMA)
requires each unit of the National Forest System to develop land management plans in accordance with the principles of the Multiple-Use, Sustained-Yield Act of 1960. These plans should be updated at least every fifteen years to reflect current conditions. Until recently, all land management plans have been guided by the 1982 Planning Rule. In order to reflect the advancements in ecology and conservation biology over the past 30 years, the Forest Service promulgated a new planning rule in 2012.

Step 7: Sampling Calculator
▶ Help
In order for users to calculate the required sample size for a new inventory and to generate estimates that meet precision requirements, one needs to implement the following equation: Required Sample Size = (CV% * t/E%)^2. 't' is the t value associated with a chosen confidence level and number of plots; CV is the sample standard deviation/sample mean, and E is the chosen allowable error, calculated as (the half width of the confidence interval)/(the estimate). The user selects E and the confidence level (and thus 't' is calculated), and must supply information that can be used to calculate CV.
This CV information can come from previous experience (for example, a user might know that the CV of volume/acre of forest in a particular area is roughly 50%), or alternatively, one can use information from ATIM to calculate CV. Needed information from ATIM includes the estimate, the sampling error %, and the sample size used to calculate the estimate. ATIM-derived CV’s are calculated as follows:
ATIM Sampling Error (%) X ATIM Estimate/100 = Standard Error
Standard Error X sqrt(sample size) = Standard Deviation
Standard Deviation X 100/Estimate = CV%(e.g., if SD/Estimate = 0.1, that is equivalent to 10% CV)
Thus with the estimate, sampling error and sample size obtained from ATIM, DTIM can calculate CV, and with this, the user-chosen allowable error and confidence level, calculate the required sample size.
The correct use of ATIM summaries to fill in the CV for this tool entails accepting certain assumptions. ATIM summaries are based on the FIA sample and plot design, in which FIA plots are located with an approximately uniform distribution across all land (both forest and nonforest) and water in the population. If the proposed plot design is substantially different or the population for which you are designing an inventory does not include all land and water, the CV coming from ATIM and used in the sample size equation may not be appropriate. Therefore, it is important to recognize that sample size estimates will be more accurate when the proposed plot design is similar to that of FIA and the definition of the population in which you plan to locate new plots is consistent with that from which the FIA sample was drawn.
Supply data for the collected fields and DTIM will calculate the sampling values. You can scroll through the output tables using the Previous and Next links.

Add your own custom objective to the current project. If you turn this project into a template, this objective will also belong to that template. Like standard objectives, your custom objective will need at least one question assigned to it in the next step of the DTIM Wizard to proceed. After creating this objective, more links will become available to edit the objective or associate questions to it under "Project Features."

A measure of variability. A value from ATIM or entered by you. Use either the ATIM CV or the CV from similar inventories as a starting point.
Equation: The standard deviation of the data divided by the mean multiplied by 100.
In order for users to calculate the required sample size for a new inventory and to generate estimates that meet precision requirements, one needs to implement the following equation: Required Sample Size = (CV% * t/E%)^2. 't' is the t value associated with a chosen confidence level and number of plots; CV is the sample standard deviation/sample mean, and E is the chosen allowable error, calculated as (the half width of the confidence interval)/(the estimate). The user selects E and the confidence level (and thus 't' is calculated), and must supply information that can be used to calculate CV.
This CV information can come from previous experience (for example, a user might know that the CV of volume/acre of forest in a particular area is roughly 50%), or alternatively, one can use information from ATIM to calculate CV. Needed information from ATIM includes the estimate, the sampling error %, and the sample size used to calculate the estimate. To calculate the CV from these data, the equation used is (Standard Error * sample size)/estimate, where Standard Error = (estimate * sampling error). Thus with the estimate, sampling error and sample size obtained from ATIM, DTIM can calculate CV, and with this, the user-chosen allowable error and confidence level, calculate the required sample size.
ATIM-derived CV’s are calculated as follows: ATIM Sampling Error (%) X ATIM Estimate/100 = Standard Error. Standard Error X sqrt(sample size) = Standard Deviation. Standard Deviation X 100/Estimate = CV% (e.g., if SD/Estimate = 0.1, that is equivalent to 10% CV).
