Objectif(s): The NWT component of this study is to examine how the anatomical features of wood from the genus Larix, vary with changes in latitude. This will be compared to work done on Axel Heiberg Island, Nunavut where a fossil forest of mummified wood approximately 45 million years old was found. Certain features of wood can provide clues to assess winter temperatures but these features vary with latitude. Therefore, assessing a set of Larix laricina from the full latitudinal range of this species will help determine the variability of modern Larix to fossil wood.

Increment cores will be taken from trees of varying diameters. Access to sampling sites will be by float plane.
