  • One study in Taiwan found that halting pesticide use along with habitat management increased a population of Taipei frogs.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. 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.
