Habitat recovery and related conservation efforts: 4
Résumé
Most lamprey and shad species are evaluated at a global scale by the IUCN red list of threatened species (www.iucnredlist.org), but at a national level this is not consistently done between countries. Below we present the conservation status (IUCN categories) of lampreys (sea lamprey Petromyzon marinus, river lamprey Lampetra fluviatilis and brook lamprey Lampetra planeri) in 2012 in the countries where such information exists (Table 4.1; from Mateus et al. 2012), and the conservation status of shads (allis shad Alosa alosa and twaite shad Alosa fallax) in 2003 (Table 4.2 to Table 4.4; from Aprahamian et al. 2003 and Baglinière et al. 2003). For lampreys, the information on the conservation status, even though rather complete, sometimes does not follow the IUCN categories, and some countries tend to adopt alternative categories that have limited comparability due to the lack of sub-criteria and standardization across countries or regions.
