Accuracy in Forestry Management

The Objective

This project considers a mathematical model that examines whether transect sampling of small forest areas statistically represents larger populations.

Methods/Materials

A model of 24 scale hectares with "tree" samples was created to represent a large population.

Random transect lines were drawn and smaller hectare samples were derived and t-tested for reliability.

Later stages of the project examined real data to examine whether the model duplicated actual field data.

Results

All of the smaller model samples failed the t-test at a 95% confidence level.

An examination of comparative real field data also indicated similar results in that most samples failed t-test reliability.

Conclusions/Discussion

Transect sampling may not adequately represent a medium size larger mother population.

This project considers a mathematical model that examines whether transect sampling of small forest areas statistically represents larger populations.
