Management
be heavier users of nutrients and
water, resulting in long-term
reduction in site productivity.
One of the main uses for wood fiber
worldwide is in production of paper.
Paper is composed primarily of
cellulose fibers from the wood.
Cellulose and lignin are two of the
primary structural elements in wood
cells. Lignin acts like glue in holding
the cellulose fibers together. Costly
chemical and mechanical processes
are utilized to remove the lignin from
wood in order to make paper.
Researchers have developed GM
trees that not only have Tess lignin but
also contain more cellulose. These
trees could obviously result in
significant savings and increased
efficiency in the paper -making
process. Concerns have been raised,
however, that trees with lower lignin
content may be structurally weaker
and less able to withstand attack by
pathogens and insects.
While most GM forestry is likely
to target plantation forests, one of the
main concerns is the potential impact
on natural forests. GM trees certainly
may have potential to invade natural
areas or interbreed with trees in
native forests, whether adjacent to a
GM plantation or some distance away
(one study suggested pine pollen
could be transported 600 km in wind
currents). Could fast growing GM
trees become invasive and displace
natural species? Is it possible for
cross-pollination to reduce lignin
content in natural forests, resulting in
structurally weak trees that are more
susceptible to insects and disease?
Could cross-pollination introduce
insect resistance that disturbs
complex ecological systems and
impacts on non -target species plus
others that depend on those species
for food?
Agriculture crops are typically
annuals or short-lived perennials and
impacts of GM crops can be
evaluated fairly quickly. Trees must
be grown for many years before long-
term implications are more fully
understood. Could there be
undesirable side effects of GM trees
that don't become evident for many
years?
