find their way into surface waters and the rivers, and should be inventoried.
Their specific threats and pathways to the human population must be under-
stood before money is allocated. We ought not to repeat the schistosomiasis
debacle of the Aswan High Dam project in Egypt or the Minimata mercury
disaster in Japan out of ignorance borne of preprocess oversights in the
interest of saving money.
A wide variety of preprocess baseline data on soils and preprocess site con-
ditions should be allowed for in each site-specific project. For example, the
potential for soil sodification or collapse following drainage and rewetting
should be anticipated to be crucial at some sites, but insignificant at other
sites. Site-specific data are essential.
Long-term management of these restored ecosystems will require plans for
monitoring and adaptive management consistent with the climate, soils, and
hydrological cycles.
The capabilities, needs, and cultures of the resident peoples will affect man-
agement strongly. Another demonstration of blatant American hubris will
simply poison all efforts to restore the Iraqi mesomarshes. We must listen
to the people who live there and follow their leadership. These restoration
efforts will not have the infrastructural support we take for granted in the
West. Adaptive management and a sense of humility will be as essential as
anything of a technical or science-driven nature that North Americans and
Europeans bring to this process.
