Forests and Timber >
The goal of reforestation is to get
trees onto treeless forest lands as soon as possible, with
a number of trees that is acceptable to the land owner or
manager, of a species of trees that is desirable, and as
economically as possible. Although there are two types of
reforestation; "artificial" is when the trees
are regenerated by planting, and"natural" is when
the trees are regenerated by "seeding," in western
Oregon the vast majority of reforestation is carried out
through tree planting.
|In general, it's quite
simple: if you cut down a bunch of trees in a forest,
then you are responsible for making sure that trees
come back on that land! Oregon has laws and regulations
that require us to regenerate the forests successfully.
In 1941, Oregon was the first state in the entire nation
to require that we reforest all state and private forest
land. In 1971 the Oregon Forest Practices Act, administered
by the Oregon Department of Forestry, was passed in
order to strengthen existing laws and, among other things,
required even more aggressive reforestation following
In 1991 the standards for reforestation
were strengthened once again to require at least 200 live
seedlings per acre, shorter time frames for planting, and
additional stand maintenance after planting. It's the law
every acre of forest land must be replanted if it is logged.
Federal lands such as Forest Service and BLM lands, are
required to be replanted too.
"Oregon is one of the
nation's leaders in reforestation. Over 100 million
new seedlings are planted on forest land each year.
That is an area equal to a six-mile wide strip from
Portland to Salem planted each year."

So how do we do it? Well,
there are several steps to getting a seedling into the ground,
and these steps are part of our management plan, because
no timber harvest should be planned without preparing for
Getting the Seedling... When
we use natural regeneration, there must be a healthy supply
of seeds available from"seed trees," or perhaps
from trees growing on the edge of the harvest unit. When
planting trees we grow seedlings in nurseries, then we take
the trees from our nurseries and replant them in the forest.
Choosing the Seedling...
We always try to use the healthiest seedlings, because the
healthier the seedling the better it will grow in the forest.
We use seeds from parent trees that have shown that they
can grow well in that particular environment. When appropriate
we try to use seedlings representing several different species
of trees in order to maintain diversity in the working forest.
||Planting the Seedling...
We plant from the onset of wet weather in the late fall,
through winter months and into the spring. Seedlings
are planted while they are dormant so that later they
can take advantage of cool, wet weather conditions that
promote good root development (in the fall and spring).
In this way the seedlings will have grown some roots
into the deep, wet, soil before the hot, dry summer
months that follow! The first step in planting a tree
is loosening the soil...
|... and then we make
a hole deep enough to accommodate the roots of the seedling,
making sure that the roots lay deep and straight...
