Field notes

Picea glauca, the white spruce, is a species of spruce native to the northern temperate and boreal forests in Canada and United States, North America.

Picea glauca is native from west-central Alaska and east across western, southern/central and eastern Canada to the Avalon Peninsula in Newfoundland, and south to Montana, North Dakota, Minnesota, Wisconsin, Michigan, Upstate New York and Vermont, along with the mountainous and immediate coastal portions of New Hampshire and Maine, where temperatures are just barely cool and moist enough to support it. There is also an isolated population in the Black Hills of South Dakota and Wyoming. It is also known as Canadian spruce, skunk spruce, cat spruce, and in its varieties, Black Hills spruce, western white spruce, Alberta white spruce, and Porsild spruce.
