How Tree Needles Age

Needle age impacts how effective the tree needle is at performing photosynthesis. Bjartmar Sveinbjornsson and Benjamin Russell research white spruce tree growth trends in Alaska’s Chugach Mountains.

How Tree Needles Age

Benjamin Russell, Rockford University, Chicago, Illinois, was in Alaska researching white spruce biology for the National Science Foundation’s Research Experience for Undergraduates program under the direction of Bjartmar Sveinbjornsson, a professor of biological sciences and the director of the Environment and Natural Resources Institute at the University of Alaska Anchorage.

In our Boreal Forest Growth project, Sveinbjornsson, Russell and Bonavia are researching growth trends of boreal forest trees in the Chugach Mountains of South Central Alaska. They look to define the specifics of how white spruce trees are growing above the treeline. Russell describes his work checking the age of tree needles in the ‘How Tree Needles Age’ video; needle age impacts how effective the needle is at performing photosynthesis.
