Its Resolution VII.14 requires contracting
parties to, wherever possible, address within their jurisdictions the environmental,
economic and social impact of invasive species on wetlands. It also suggests to
“review existing legal and institutional measures and, where necessary, adopt legis-
lation and programmes to prevent the introduction of new and environmentally dan-
gerous alien species and the movement or trade of such species within their
jurisdictions”.
The
Bonn Convention for the Conservation of Migratory Species of Wild Animals
(
1979
) outlines in Article III(4)(c) that contracting parties are “to the extent feasible
and appropriate, to prevent, reduce or control factors that are endangering or are
likely to further endanger the species, including strictly controlling the introduction
of, or controlling or eliminating, already introduced exotic species”.
