- REFORESTATION
-
- The purpose of this written report is to inform the reader about the concerns and facts involved with
- reforestation. Reforestation began in Ontario after World War II. What happened was, professional foresters
- were assigned to an area and became responsible for its well being. Under the Crown Timber Act, long term
- management was prepared. Then the many steps needed to rebuild a forest began.
- Included in this report will be information on the effects of cutting and replanting, such as Carbon Dioxide,
- and Global Warming. Following this will be methods for planning a forest, and how they are conveyed before
- planting in a forest begins.
- There are many reasons why forests are cut down. One is to benefit economically, with furniture and home
- building. But there is also another reason. Arguments say "the United States could help slow the atmospheric
- accumulation of carbon dioxide by replacing old-growth forests with faster-growing young trees". A new study
- of young and old forests says how this is in fact not true. Loggers have said that new trees pull the carbon
- dioxide better than old trees, and this may seem true, but it is not. There is one point being overlooked from
- all of this. The older, larger trees can store much, much more carbon dioxide than a new tree could. By cutting
- and burning these magnificent seasoned trees, the CO2 is being released back into the atmosphere. These releases
- of carbon dioxide add up in our surroundings, only to intensify Global Warming. Although this shows what happens
- when one burns and cuts down old forests, one must still plant new trees for long term plans, not letting them
- grow for a few years, to then cut them down.
- There are many methods for planning a forest. The simplest method of replanting a forest is to leave it to
- nature. A suitable seed bed in which trees will readily take root is integral for successful regeneration.
- Reducing competition by eliminating grass, weed or shrubs is another requirement in securing a new crop of trees.
- These will sprout to produce seedlings. Though the weeds were eliminated before, they still grow back, and
- because of this poor, quality trees will grow. Another method though, is to create a planned forest, where new
- conifers are grown from seed in a special nursery. Seeding is a reforestation technique used mainly in the Boreal
- forest area where fire or logging tends to leave no or very little seeds for growth. In specific cases, Ministry
- staff seed the area with treated tree seeds. Following this is the planting. In many cases, planting is the
- only means of initiating a new forest. Up to 80 000 000 trees are planted annually in Ontario on Crown and
- private land. Usually immature forests have to be tended to. Once situated, a new crop needs intermittent care
- for the next 60 to 100 years. This means continuing protection from fires, disease and insects and routine
- thinning to focus the growth on selected crop trees.
- Before a forest can be grown, certain procedures must first occur. Collecting and processing seeds is one of
- them. Tree flowers fertilized by blowing winds or insects generate seed, in a time of somewhere within 1 to 2
- years. Seed collecting from the woods must be timed with periodically occurring good seed years. Angus, near
- Barrie, is where all forest tree seed collection is co-ordinated. Stock of seeds can value up to $500 000.
- Usually this is around 3 billion seeds from 59 tree classes.
- In summary of the aforesaid, trees are very valuable to the human race economically and for health. Without trees
- the environment could worsen to the point where we would be living on one large dessert. We must remember that
- forest do not grow as easily as they used to because of fires and other disasters. This is why many forests are
- planned, and cared for. Most of us will never now how they turn out because for a forest to completely grow,
- it needs within anywhere from 60 to 100 years or more.
- There are many reasons why we should have reforestation. One being mostly that we need forest to live! Without
- forests, or any type of plant, the carbon cycle can't result. There are not many arguments against reforestation,
- but there can be some opposition for the land being used between a large business company and the Ministry.
- I feel replanting of forests is very crucial to the human race. The earth depends on many cycles, where one
- organism depends on the other because of what it does. We, exhale carbon dioxide which the trees take in, while
- they give off vital oxygen.
- In closing, we live in an age of technology, leaving behind us the past. With the past we are forgetting forests;
- we must make sure this doesn't happen.
