A Bark Thickness Model for White Spruce in Alaska Northern Forests

الملخص EN

Here we developed a simple linear model to estimate white spruce bark thickness in the northern forests of Alaska.

Data were collected from six areas throughout interior and southcentral Alaska.

Geographic variation of bark thickness was tested between the Alaska statewide model and for each geographic area.

The results show that the Alaska statewide model is accurate, simple, and robust, and has no practical geographic variation over the six areas.

The model provides accurate estimates of the bark thickness for white spruce trees in Alaska for a wide array of future studies, and it is in demand by landowners and forest managers to support their management decisions.
