The Aspen Tree: A Closer Look
You are hiking along a gorgeous canyon in the foothills of the Sierra Nevada Forest. You come across a small creek. Surrounding that creek, you see a stand of hundreds of Aspen Trees slowly rustling in the wind. You wonder, are these trees part of something bigger?
Well, you’d be right to think that. In fact, Aspen trees are considered one of the largest organisms on the planet with an resilient life force that resides underground in the form of an extensive root system. These roots can remain dormant or inactive for many years until the right conditions, such as sufficient sunlight, allow for a stand of trees to grow above ground. A stand of trees is also called a “clone” because each individual tree is genetically identical, creating one large organism. Fungi also operate this way. Fascinatingly, if a single Aspen clone was removed from the stand, its tough root system would barely be affected because it reproduces so rapidly!
In deciduous forests, Aspen trees can quickly colonize recently burned or bare areas. Their thin, white outer bark protects a green photosynthetic layer underneath which helps the trees to create sugars and thrive in sub-optimal conditions, often times when other deciduous trees stay dormant. This sugary layer can then provide dire nutrients for wildlife such as deer or elk during hard winters or when food is scarce.
The oldest and heaviest known Aspen stand can be found in Utah's Fishlake National Forest. It is rumored to be over 80,000 years old and weigh nearly 6,600 tons.
What an awesome tree!

I would love to see a tree like this in a closer look! Will definitely go to this place.
Pruning is basically the act of removing dead and overgrown branches from trees and shrubs. Pruning trees encourages growth, and there are other reasons for doing it as well, such as to remove dangerous branches, branches that are rubbing against each other, branches that are too close to the roof or to power lines, and to get rid of weak or infected branches.

Nice! This will be a great addition to my knowledge about plants.

What an interesting blog! This should be spread more widely so that people are aware that there are trees that grow only in certain countries.
