| Typical dryland or upland varieties (varieties grown in watered but not flooded fields) in Hawaii are ''lehua maoli'' and '''bun long''', the latter widely known as Chinese taro. ''Bun long'' is used for making taro chips. ''Dasheen'' (also called "eddo") is another "dryland" variety of ''C. esculenta'' grown for its edible corms or sometimes just as an ornamental plant. | | Typical dryland or upland varieties (varieties grown in watered but not flooded fields) in Hawaii are ''lehua maoli'' and '''bun long''', the latter widely known as Chinese taro.

− | The Hawaii Agricultural Statistics Service puts the 10-year median production of taro in the Hawaiian Islands at about 6.1 million pounds (2,800 t; Viotti, 2004). However, 2003 taro production in Hawaii was only 5 million pounds (2,300 t), an all-time low (record keeping started in 1946). The previous low, reached in 1997, was 5.5 million pounds (2,500 t). Yet, despite generally growing demand, production was even lower in 2005: only 4 million pounds, with ''kalo'' for processing into ''poi'' accounting for 97.5% (Hao, 2006). Urbanization has driven down harvests from a high of 14.1 million pounds (6,400 t) in 1948. But more recently the decline has resulted from pests and diseases. A non-native [[Ampullariidae|apple snail]] (''Pomacea canaliculata'') is a major culprit in the current crop declines.
