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 ttested 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 ttest at a 95% confidence level.
An examination of comparative real field data also indicated similar results in that most samples failed ttest 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.
