350px|Conceptual representation (2x2 table) of sources , sinks, ecological traps, and perceptual traps. Adapted from Patten and Kelly (2010) A perceptual trap is an ecological scenario in which environmental change, typically anthropogenic, leads an organism to avoid an otherwise high-quality habitat. The concept is related to that of an ecological trap, in which environmental change causes preference towards a low-quality habitat. History In a 2004 article discussing source-sink dynamics, James Battin did not distinguish between high-quality habitats that are preferred or avoided, labelling both "sources."Battin, J. (2004) "When good animals love bad habitats: ecological traps and the conservation of animal populations" (PDF), Conservation Biology, 18: 1482–1491 The latter scenario, in which a high-quality habitat is avoided, was first recognised as an important phenomenon in 2007 by Gilroy and Sutherland,Gilroy, J. J., and W. J. Sutherland. (2007) "Beyond ecological traps: perceptual errors and undervalued resources," Trends in Ecology and Evolution, 22: 351–356 who described them as "undervalued resources." The term "perceptual trap" was first proposed by Michael Patten and Jeffrey Kelly in a 2010 article.Patten, M.A., and Kelly, J.F. (2010) "Habitat selection and the perceptual trap," Ecological Applications, 20: 2148–2156. Hans Van DyckVan Dyck, H. (2012) "Changing organisms in rapidly changing anthropogenic landscapes: the significance of the ‘Umwelt’-concept and functional habitat for animal conservation," Evolutionary Applications, 5(2): : 144–153. argues that the term is misleading because perception is also a major component in other cases of trapping.
