Norway Spruce

Basic Information
Tree ID: 
200
Family: 
Pinaceae (Pine)
Genus and species: 
Picea abies
Description: 
The Norway Spruce is a highly versatile and resilient tree. The Norway Spruce is a conifer gymnosperm and an evergreen tree that bears pine cones. This classification signifies that the tree relies on wind pollination and bears “naked seeds” on its large cones. It is monoecious, with both male and female cones on the same tree. This tree has a pyramidal form, and its leaves are opposite. The leaves are needle-like and are attached to the tree branch through a woody structure called the sterigma or the pulvinus. The bark of the Norway spruce is thick and flaky, with gray-brown scales.

Bark
The bark of the tree is in the form of thick scales and of a gray-brown color. The corners of the bark are flakier and thin. The bark of the tree gets thicker with age, starting as thin flakes and gradually thickening to the texture that it has during this moment of observation.
Twigs & branches
The Norway Spruce has several branches that originally grow upwards, and then outwards. This gives the tree the pyramidal shape that it exhibits. The Norway Spruce has tree branches that extend into several twigs, or branchlets, that bear green, needle-like leaves. These branches are horizontal or slightly upturned, depending on the weight that they bear. These leaves are described to be four-angled and in this tree, are about 1/2 inch long. As the tree grows and the branches extend, they tend to assume a "drooping" silhouette due to the weight of the branch, especially near the bottom of the tree. The branches are sturdy, allowing them to survive during snowstorms and avoid breakage during temperatures that fall below the freezing point.
Foilage
The foliage consists of dark green needles that populate the branches of the Norway Spruce. These needles are quadrangular, or four-angled, in cross section and assume opposite arrangement on the branch, extending toward the tip of the branchlet. On this tree, the needles are about half-an-inch long, but can extend up to an inch in length. The dense population of needles on the branch, as well as the drooping of the branches, gives the tree a pyramidal look with lush, green foliage. The needles are attached to the branch through small, wood structures called the sterigma or the pulvinus.
Reproductive Structures
The tree, as a gymnosperm conifer, produces "naked seeds" that reside in its cones. Unlike angiosperms, their seeds are not enclosed in fruit and do not rely on pollinators for fertilization. This species is particularly recognized for its larger cones. The tree relies on wind to disperse the seeds and spread them for reproduction. The cones are elongated and slender as well, ensuring the protection and wide dispersal of their seeds. The cones range from about 4 to 7 inches long and 2 inches wide. The tree is monoecious, which means that it has male and female cones on the same tree, with female cones on the upper branches and male cones on the lower ones to prevent self-pollination. The cones open in the warmer days of the late autumn or winter. The male cones are reddish-yellow and contain sporangia that produce microspores that develop into pollen for dispersal. The female cones are red or purple in color and contain ovules that point upright to catch the pollen in the spring. When they are pollinated, they transform into a brown color and turn downwards for maturation. This reproductive cycles spans two years.
Fruit
As a gymnosperm, this tree does not bear fruit, but instead produces cones with naked seeds.

Research
Natural range of distribution: 
Habitat: 
The Norway Spruce is accustomed to habitats that are cool and moderate in climate, aligning with its original region in northern, eastern, and central Europe. They thrive in mountainous regions and cooler climates such as boreal forests where the temperatures are freezing several months of the year. It typically occurs in pure stands, meaning it is the dominant tree in the total canopy of the forest area. In certain regions, it can be spotted with the Scotch pine, European beech, and the European Silver fir. Norway spruce thrive in nutrient-rich, moist soil.
Origin, history, and uses: 

The origins of the Norway Spruce trail back to northern, eastern, and central Europe. More specifically, however, it belongs to the European Alps, the Balkan mountains, and the Carpathian Mountains, which all run through Romania, Slovakia, Poland, Ukraine, Czech Republic, Serbia, and Austria, to name a few. It was said to be introduced to the British Isles in 1500 AD, and then introduced to America in the 18th and 19th centuries.  Now, it has spread to the northeastern region of the United States, southeastern Canada, the Pacific Coast states, and the Rocky Mountains. They are found in Connecticut, Hawaii, Illinois, Indiana, Maine, Massachusetts, Michigan, New York, and Pennsylvania. Its arrival occurred in Woods Hole, Massachusetts, for a large-scale planting project started by European immigrants. In the 1930s, the Civilian Conservation Corps planted several seeds as part of the reforestation project. The Norway spruce is fast-growing and adaptable to cold climates, making it a formidable and versatile tree for the project. 

In Ancient Europe, the tips of the Norway Spruce were used for brewing beer. The durability of the tree has made it a symbolic product as a part of culture. In fact, Norway has send a spruce tree to London every year since the end of World War II in 1947. This gesture is one of hope for their lasting relationship.  

 

The strong wood and rapid growth rate of the Norway Spruce make it a coveted forest product. Its wood is used for paper and as components of string instruments. In the cultural sphere, it is also a useful Christmas Tree. It is also suggested to have medicinal benefits, and its shoots are used to treat gastrointestinal and respiratory ailments.  

 
Phenology: 
The Norway Spruce is dormant during the winter and the buds of the cone are tightly closed. The needles remained intact and green during the winter. As the temperature rises in spring, pollination occurs from May to June, and new leaves emerge during this time as well. The cones open in late autumn where the seeds are released and matured.
