Editing Periodical cicadas (section)

===Impact on other populations===
Cycles in cicada populations are significant enough to affect other animal and plant populations. For example, tree growth has been observed to decline the year before the emergence of a brood because of the increased feeding on roots by the growing nymphs.<ref name="Yang" /> [[Mole (animal)|Moles]], which feed on nymphs, have been observed to do well during the year before an emergence, but suffer population declines the following year because of the reduced food source.<ref>{{Cite web |url=http://news.nationalgeographic.com/news/2007/05/070530-cicadas-food.html |title=National Geographic: Cicada Outbreaks Linked to Other Animals' Booms, Busts. |access-date=23 June 2009 |archive-url=https://web.archive.org/web/20080722221700/http://news.nationalgeographic.com/news/2007/05/070530-cicadas-food.html |archive-date=22 July 2008 |url-status=dead }}</ref> [[Wild turkey]] populations respond favorably to increased nutrition in their food supply from gorging on cicada adults on the ground at the end of their life cycles.

Cicada broods may also have a negative impact. [[Eastern gray squirrel]] populations have been negatively affected, because the egg-laying activity of female cicadas damaged upcoming [[mast (botany)|mast]] crops.{{Citation needed|date=June 2011}}
