Stewardship - Vegetation Resources Inventory

The Vegetation Resources Inventory is designed to answer two questions:

  1. Where is the resource located?
  2. How much of a given vegetation resource (for example, timber or coarse woody debris) is within an inventory unit?

Process

The Vegetation Resources Inventory is carried out in two phases: 

  1. The photo interpretation phase involves estimating vegetation polygon characteristics, from existing information, aerial photography, or other sources.
  2. The ground sampling phase provides the information necessary to determine how much of a given characteristic is within the inventory area.

Net Volume Adjustment Factor (NVAF) sampling collects data on a number of selected trees to account for errors in the estimates of net tree volume.

Inventory projection (growth and yield) encompasses both the tools, models and their data requirements (permanent sample plots) that are used to estimate and predict tree and stand parameters, such as volume.
