FBRI Graduate Fellow: Halli Hemingway

Halli’s Project

Dr. James Arney developed a methodology for defining which tree growth factors are a result of good silviculture practices and which tree growth factors are a result of soil, water and other environmental factors.
In her FBRI Fellowship, Forestry Masters student Halli Hemingway conducted field studies to prove the methodology.
At the basic level, the methodology studies tree growth rings at 10 meter increments. For her study, Halli spent her time conducting tests in Idaho forests.

Halli has graduated and is currently working for Bennett Lumber Products. There is a link to Halli's published work in the SAF Forest Science Journal.

Halli compared traditional height-age modeled growth rates to observed growth rates in Northern Idaho. The modeled growth rates consistently underpredicted height growth.

Halli explored the accuracy of productivity predictions using 10-meter site index and a nonparametric approach. One method accurately predicted 100% of test sites and was chosen to create productivity maps of the region.

The new method of defining forest productivity is helpful to forest managers, ecologists, forest biometricians, and climate change experts by making their projections more accurate. More …

This project was done in collaboration with Mark Kimsey, Forestry professor at the University of Idaho.
