Spruce Trees Report


The Spruce tree or the picea is a tree found commonly around the Jackson Hole area. The tree ranges from 20-60 meters tall, and is distinguished by its whorled branches and needles. The needles are attached to a single branch that is in a spiral fashion. They are sharp and have 4 sides with light stripes, and put out a bad smell when they are crushed. Cones of the tree usually hang at the end of the branch, have very thick scales, and grow separately or in pairs.
The spruce tree is commonly found in the eastern part of the Rockies and the west. The climate they live in is a continental climate which usually consists of dry winters that are very cold. Soil is very important to the tree and usually has to have aerated moisture, stream sides, and they don’t grow in marshes. Some different kinds of the Spruce are Blue spruce, Norway, Morinda, Wilson, Black, and Engelmann.
Spruces are used for many different reasons and support their niche. The tree is one of the most important uses for paper manufacture. They are also commonly used as Christmas trees. Larvas use the tree as a main food source and lie inside the tree in places called galls. These larvas do not cause that much harm to the tree.
How the tree reproduces is by the cones of the tree, and the ones with pollen are a reddish color. Then by succession most spruces burn due to there suitable habitat and grow close to the ground. This will cause the cones to fall and plant in the soil.

Great physical description of the spruce as well as its environment. More details could be added about the dependence of larvae on the spruce, and the impact and definition of galls. In addition, your last few sentences regarding succession are heading in the right direction, but are a little confusing.
