Floral hazards: nootka lupin in iceland and the complex politics of invasive life

Once established in new spaces, exotic plants not only impact the "native" biota, but also affect environmental politics in often complex ways. This article looks into one instance of such politics: that of the Nootka lupin (Lupinus nootkatensis), a leguminous plant of North American origin. Imported to Iceland in 1945 to stem soil degradation and recover vegetation, it soon became firmly established in Icelandic landscapes. Its spreading was actively assisted by human actors as part of fulfilling a moral duty to heal a land scarred by unsustainable past land use practices. Changing perspectives in environmental management have brought about a radical reversal in the lupin's status. It is now seen by many as a "floral hazard", and has been declared an "invasive alien species" by the Ministry for the Environment. New lines of defence are being established to curb its spread into the deserts of the central highlands. A polarized debate has ensued about the politics of invasive life. Increased research by natural scientists has not led to any resolution. It is argued that such seemingly intractable controversies cannot be resolved unless close attention is paid to the historical construction of values and moralities underwriting the production of the discursive communities involved. Conditions of radical uncertainty with the advent of the Anthropocene further complicate the politics of invasive life.
