Picea Mariana, commonly called black spruce, is a species of coniferous tree native to northern regions of North America. While this common name is widely recognized, there are several other synonyms used to refer to this tree species. Some of the alternative names include swamp spruce, bog spruce, jack pine spruce, and Canadian spruce. Additionally, the Latin name Picea nigra is often used interchangeably with Picea Mariana. Despite varied nomenclature, all of these names refer to the same hardy evergreen tree that thrives in cold and wet environments, and serves as important habitat and food source for various wildlife species.
