Black Walnut Tree (Juglans nigra)
Observation
This walnut tree was observed on 25 September 2011 on my neighbor's property. I observed this tree for several minutes as it first caught my attention because squirrels climb it often looking for nuts. It also caught my attention because another tree occupies the same space as well.The ground below the tree is currently covered with leaves and nuts that have fallen. In the later half of the summer, the nuts begin dropping from the tree and hit the payment like a sledge hammer. I quickly took the picture to avoid being pummeled by any remaining fruit. The tree stands about 30 or 40 feet tall and provides shade in the summer months.
Questions
What is the primary use of the black walnut? How are the walnuts consumed? What are some uses of its shell?
Scientific Research
Williams, Robert D. Silvics of North America, Vol. 2, (Dec., 2001), pp. 390-397.
The Black Walnut Tree is widely used for it lumber and veneer. The wood is used in the manufacturing of furniture, interior paneling and gun stock. The nut is a source of food for wildlife and humans. Squirrels eat the nuts. Humans use the nuts for baking food and in ice cream
Walnut shells have many uses as well. The shell is ground for use in beauty products such as skin exfoliants and soap. The shells are used as abrasive blast media for cleaning. They are used as bedding for pets such birds, reptiles and some small animals because they resist mold and bacteria.
Also, the ground shell has industrial uses such as cleaning jet engines and as lost circulation material to combat operational problems associated with oil drilling.
