196 Forests
Reforestation
Ancient forests (old forests that have never been cleared or seriously damaged)
are increasingly rare. Once an ancient forest is gone, it will never grow back to
contain the variety of plant and animal life that it had before. But secondary
forests (forests that have been damaged but are growing back) can provide
many of the same resources as ancient forests if they are allowed to grow and
maintain biodiversity. And forests planted by people and managed well can
also provide many resources to support community health.
A healthy forest takes a long time to grow, but there are things you can do
to give it a good start. Controlling erosion, preparing the soil, and planting
native trees or trees that are appropriate to your area will help a forest grow
well. Following the natural order of tree growth in forests is another way to
help produce a healthier forest (see Chapter 11).
Is planting trees always helpful?
Before beginning a community reforestation project, be sure it will meet the
needs of your community and your local environment. Trees may compete with
crops for limited water and land. Sometimes it is too much work to care for
young trees in harsh environments. Planting trees where they cannot or will
not be cared for leads to failed projects and dead trees.
If your community relies on forest products, such as timber or fruit,
planting trees may be a good way to quickly bring back forest resources. If
your community mainly relies on the forest for providing hunting grounds or
protecting soil, air, and water, then you may benefit more by protecting areas
of land from being used while trees regrow on their own.
Forests are not right for all places. Few trees grow naturally in deserts,
marshes, or grasslands. If people try to plant trees in these places it may disturb
the balance of plants and animals. But in other places where there are few trees,
such as in cities and towns, planting trees along roads, near factories, and in
parks may greatly improve the health and well-being of the community.
Who owns the land, and what are the laws?
If you want to reforest land and use its products later, be sure you will be
allowed to use the forest once it is grown. Knowing who legally owns the land
and getting permission before planting trees can help avoid problems later.
Land that once was poor and barren will become valuable once it is covered by
healthy forest. Also, some places have laws that prohibit people from cutting or
using certain trees, even if they planted them themselves. Find out if there are
such laws where you live.
