Old-Growth is a term used to describe forests that have not been subjected to the destruction of human hands or machinery. Old-growth forests have not gone through any forced alterations such as logging, burning etc. for over 100 to 150 years. Old forests are made up of a variety of aged trees, some young, some fully grown, and some expired trees that are still standing. These trees also provide habitation for an assortment of wildlife animals. One significant fact about these old forests is their ability to recover quickly from natural destruction such as windstorms or fires, however it can take decades to recover from the destruction of human hands such as logging. There is much controversy associated with the question of whether to leave these forests standing or cut them down and replace them with younger faster growing trees.
The controversy surrounding old-growth trees stems from which option is better at sequestering and isolating carbon from the atmosphere. There is much debate within the scientific groups as to whether old-growth forests or fast growth forests isolate carbon most efficiently. Some insist that the younger faster growing trees will store and capture more carbon. M. Harmon,
