trees quintupling in size. Seeing the positive effects wolves had on trees, more national parks and states began facilitating this natural ecology management. By initiating a wolf presence in certain areas, a trophic cascade occurs and thus allows for tree recruitment and renewal. Yellowstone is not the only park to introduce wolves to affect trees, but allowed for the movement to gain popularity,…

12 years ago, in an isolated island, the robin population was happier than ever. They had the whole island to themselves and to many insects. The island was full of vegetation that gave them and the insects a home. The soil was soft and moist and easy for them to break apart. Food wasn’t a problem for them. They could easily pick off insects from leaves or pluck them out from the soil. Food was abundant and varied. Because of the accessibility of food, the robins had no special advantage one…

of me grew when I seen something that I thought was impossible. My heart was racing, my eyes were huge, the words coming out of my mouth were not making any sense, I was stuttering over and over again. There's a truck suspended from the mountain, a tree is holding it up, it looked like it was from lifetime ago. Suddenly the sounds of the waterfall snap me back to reality and I know that I am getting closer and closer to the breathtaking beauty that is known as Amicalola…

A mighty Oak. It’s limbs towered above the clouds and held itself above us like a giant. It was as broad as molasses and substantial like diamonds. Engraved on it was the word Friendship. “Stupid, stupid tree!” I thought. “You aren’t friendship. Your hatred and enmity!” Before Enonya even knew what hit her I screeched “Sorry!” As I was saying this a flock of crows flew out of the trees. They knew something was erroneous. Soon after she responded with an…

(875 words) Woolly Days ahead for the Hemlock Tree -Angela Cannon-Crothers I like bugs, ask anyone. I am awed by the mechanics of their life cycles, the biodiversity of the entire Order of Insecta, the magical beauty of so many of their kind. But there are a few that strike more than a few heebe-geebes -- some are downright frightening.

Once upon a time, there was a population of Ents (tree beasts) that inhabited trees. They could move through trees, and would protect a forest at any cost. They were huge, about the size of a large oak, and took on the form of whatever tree they were currently inhabiting. As soon as a Ent moved into a tree, the tree could move as the Ent it. Therefore, if there was a nearby forest, an attack from Ents was almost impossible to defend from, even if there were two or three Ents. Ents came in…

The sun was barley shining because of all of the dense fog, which was just above the tree tops. What sun did come through made the light seem almost as if you were in a dream. As I continued down the path, the smell the salty air of the ocean permeated my lungs. The salty sea air mingled with the smell of fresh earth and life. The…
