A study in 1999–2006 of a water lily paddy field in Taipei County, Taiwan (Lin et al. 2008) found that stopping using pesticides along with habitat-improvement work doubled a population of Taipei frogs Rana taipehensis. In 2002, a farmer stopped using herbicides and pesticides on his field, which was at the centre of the frogs’ breeding habitat. By August 2003, the Taipei frog population in the field had more than doubled (from 28 to 85) and the farmer fully adopted organic-farming practices. Pollution from river construction work resulted in a drastic decline in the population in 2004–2005 (20 to 4), but by 2006 the population appeared to be recovering (19). Habitat-improvement work included cutting weeds in the field.
