Intermediate
Phase:
What to do in 30-50 years
Written by Anna Simon
In the intermediate term, the data from the
experimental
restoration sites should be analyzed to improve existing restoration
techniques. These techniques should be implemented in appropriate
areas. Research and monitoring should be continued, although they
might
not have to be funded so heavily.
Potential
for Future Scientific Advancements
Written by Sara

The wetlands of Louisiana
play a vitally important role in protecting the city from flooding and
storm
surges. But scientists and researchers
have just begun to tap into their potential.
If we work to prevent the further degradation of the
wetlands they will
provide an avenue for future study and a wealth of biological resources. Wetlands are complex ecosystems, and there is
still much that we don’t know about them.
The Louisiana wetlands
make up about
40% of the total wetland ecosystems in the United States (Thorpe,
2002), and
they are in an area of great geological activity. This
means that the area will be extremely
important for future study of geological and ecological processes such
as the
effect of subsidence on the wetlands, plate tectonics in areas of soil
instability, the role of different species in wetland ecosystems, and
many
other things.
There are also studies beginning now that
are looking into
the role of wetlands in carbon sequestration (Wetland Restoration,
Management,
and Carbon Sequestration , 2003This work is extremely important because
atmospheric carbon affects global warming, and the ability to store it
in
wetlands would help to remediate these affects.
In addition to naturally sequestering carbon, the wetlands
naturally
purify the water that flows through them.
For this reason they can be used for the treatment of
effluent from
cities. This process has been
implemented within small-scale artificial wetlands, and research is
being done
to evaluate the possibility of using natural wetland ecosystems for
this
purpose (Gustufson, 2002). If this could
be applied in New Orleans
or another city, then thousands of dollars could be saved in energy
costs
compared to conventional wastewater treatment facilities.
Finally, the wetlands are currently a
warehouse of genetic
information. Many of species that
inhabit the wetlands are currently endangered or threatened, like the
bald
eagle, or are commercially important to the area, like fish and
shellfish. As the ecosystems disappear so
do the species
that inhabit them. Future studies should
focus on preserving this biodiversity.
