Prior to the Earth Summit and during the
period 1982 and 1988, the Scientific Committee
on Problems of the Environment (SCOPE)
engaged a large number of scientists in an
effort to document the nature of the invasive
species "problem" which has resulted in a
book entitled "Biological Invasions: A Global
Perspective" by Drake et al. (1989) (Mooney
2000). CBD Article 8h states that each
Contracting Party shall, as far as possible and
appropriate "present the introduction of, control
or eradicate those alien species which threaten
ecosystems, habitats or species.
