Spruce Pollen on Lake Iliamna
Every few years yellow/orange pollen forms on some spruce trees. When it releases and gets windblown streaks of it float on the lake water. What is this pollen? Why is it only on some trees? Why does it occur in some years, not all? Two pics are attached to help with the id.
I don't think this is pollen. I suspect it is some kind of fungal blight. Do you see this uniformly on the tree or most concentrated around the cones?
Thanks Stephen. The yellow/orange powder is all over the tree from low to high but mostly on the outside ends of the branches. There are no cones on the trees that I see, altho there were cones earlier but most if not all were blown to the ground on windy days. There are spruce trees all over the village. Not all have the "blight". It's very inconsistent. What is the blight called? If I see a picture I can compare it to what I'm seeing here. And what causes the blight? I'm attaching a few more pics.
Thanks Jesse for the informative response. Very interesting. Especially the connection between the spruce trees and Labrador tea.
