Red Listing crop wild relatives
It’s kind of buried in the IUCN press release, between giraffes and freshwater species, but there’s good news for researchers interested in crop wild relatives.
With this update, the first assessments of 233 wild relatives of crop plants such as barley, oats and sunflowers have been added to the IUCN Red List. Habitat loss, primarily due to agricultural expansion, is the major threat to many of these species. The assessments were completed as part of a partnership between Toyota Motor Corporation and IUCN, whose aim is to broaden the IUCN Red List to include the extinction risk of many species that are key food sources for a significant portion of the global population.
Crop wild relatives are a source of genetic material for new and existing crop species, allowing for increased disease and drought resistance, fertility, nutritional value and other desirable traits. Almost every species of plant that humans have domesticated and now cultivate has one or more crop wild relatives. However, these species have received little systematic conservation attention until now.
Four mango species have been listed as Endangered, and the Kalimantan mango (Mangifera casturi) has been listed as Extinct in the Wild. These species are relatives of the common mango (Mangifera indica) and are threatened by habitat loss. Native to South Asia, mangoes are now cultivated in many tropical and sub-tropical countries and they are one of the most commercially important fruits in these regions.
A relative of cultivated asparagus, hamatamabouki (Asparagus kiusianus), which is native to Japan, has been listed as Endangered due to habitat loss caused by urban expansion and agriculture. Loss of habitat is also the main threat to the Anomalus sunflower (Helianthus anomalus) which has been listed as Vulnerable and is a relative of the sunflower (H. annuus). Cicer bijugum, native to Iran and Turkey, is a wild relative of the chickpea (C. arietinum); it has been listed as Endangered due to habitat conversion to agriculture.
“Crop wild relative species are under increasing threat from urbanisation, habitat fragmentation and intensive farming, and probably climate change,” says Mr. Kevin Butt, General Manager, Regional Environmental Sustainability Director, Toyota Motor North America. “To conserve this vital gene pool for crop improvement we need to urgently improve our knowledge about these species. Toyota is pleased to provide support for the assessment of these and other species on The IUCN Red List.”
Unfortunately, there’s no way to search the Red List just for all crop wild relatives, but here’s the entry for Anomalous Sunflower for you, because I like the name.
