MANAGED FORESTRY
In the 20 years between 1935 and 1955, timber
volumes in Michigan’s upper peninsula decreased, while during this time
sawtimber volumes in the lower peninsula increased
substantially. Why the difference? The bottom of the
sawtimber supply barrel in the (northern) lower peninsula had been reached
a number of years earlier and industrial activity and sawtimber demand had
dried up. Early cutting and fires had been much worse there, but still the
forests came back. After the big mills were gone, the timber grew, while
in the UP aggressive demand and cutting continued to seek out the
remaining old growth and good quality wherever it existed, cutting at a
rate much faster than wood was being replaced by growth of the remnants
and young trees in second growth stands. But here the comparison ends. The
bottom of the barrel was never reached in the UP, and consequently
industrial activity and demand did not disappear. Yet a dramatic change
did occur. Shortly after 1930, some of the large forest landowners began
to make conscientious efforts to adopt improved management practices in
cutting old growth stands. To the extent possible under local conditions,
a growing forest was left after the oldest trees were removed. This
practice is called "selective management," and from that time on it had
spread in use to more and more lands. These lands, even though recently
cut (selectively) have in many cases produced a second crop, and will
continue to do so at regular, fairly short intervals. This is the essence
of good hardwood management, and the foundation of the recovery of the
Upper Peninsula’s forest wealth. Today, Michigan's
forestry industry is dominated by privately-owned lumber and paper
companies. Mead and Champion are two of the largest, and together
they own many thousands of acres of forest throughout Michigan (but
especially in the UP).
