FRM 121 Timber Resource Inventory

What parameters are essential for understanding healthy forest dynamics?

Which factor most significantly influences the budgeting of a forest resource inventory?

What determines the periodicity of a forest inventory?

Given a circular plot with a radius of 5m, what would the area of the plot be?

If the Area Factor ($Af$) is 30ha and the Site Index ($SI$) is 10%, what is the significance of these values in a timber inventory?

Timber Resource Inventory

Essential for assessing forest dynamics through birth, maturation, and death parameters.
Requires data on productivity, including species composition, tree size distribution, and volume increment.
Provides the groundwork for effective forest management planning.

Forest Area Influence

The size of the forest directly affects the inventory budget.
Larger forest areas require more comprehensive resource inventory approaches.

Periodicity of Inventory

The timing of forest inventories is contingent on the inventory's objectives and management intensity.
High management intensity may necessitate more frequent updates to inventory data.

Circular Plot Sampling

Circular plots are used to estimate various forest parameters.
Plot specifications include radius (e.g., 5m), site index (e.g., 10%), and total area (e.g., 30ha).
The number of plots (Np) can be derived based on the sample area and predetermined plot size.

Example Problem Overview

An example problem posed involves understanding sample area and plot number within a specific forest context.
Circular plot types vary and are determined by specific area and management needs.

This quiz focuses on timber resource inventory essential for managing healthy forest dynamics. Participants will provide values related to the birth, maturation, and death parameters of trees, as well as analyze species composition and tree volume increment for effective forest management planning.
