Alien plants of Fuerteventura, Canary Islands. Plantas extranjeras de Fuerteventura, Islas Canarias - korrigierte Fassung vom 23.01.2002 - Prof. Dr. Dietmar Brandes, Dipl.-Biol. Katrin Fritzsch. Arbeitsgruppe für Vegetationsökologie und experimentelle Pflanzensoziologie Botanisches Institut und Botanischer Garten der TU Braunschweig D-38023 Braunschweig. Abstract: The nowadays flora of Fuerteventura contains some 780 species. At least 119 species are aliens, some 150 further species of mediterranean and/or North African origin are probably introduced too. The estimated percentage of aliens therefore reaches 35 %.

Acta Botanica Malacitana 26 264-276. [English abstract] We have included also some unpublished recent data within this list. The species have been arranged first by their invasive character (from higher to lower). Within the most aggressive, species have been presented by their morphology (herbaceous, woody, and so on). Within species are alphabetically listed. Consideration of `Invasiveness' follows the recent proposal by Richardson, D., Pysek, P., Rejmanek, M., Barbour, M.G., Panetta, F.D. & West, C.J. 2000.

Pat Enwright (2003) Adventive species of the Wellington Conservancy ecological district. Project initiated by John Sawyer of D.O.C and further refined and updated by Colin Ogle of Wanganui before Ewen Cameron and Mei Nee Lee of the Auckland Museum herbarium very kindly provided lists of adventive species by ecological district for the Wellington Conservancy from the AK database. I must also thank Ewen Cameron and Rhys Gardner for identification of a number of specimens included in this list, Phillipa Crisp from W.R.C. also supplied information on species recorded by or on behalf of W.R.C and not already included in the database.
