Trees can be [[Pollination|pollinated]] either by wind or by animals, mostly insects. Many angiosperm trees are insect pollinated. Wind pollination may take advantage of increased wind speeds high above the ground.<ref>{{cite web |url=http://www.treesforlife.org.uk/forest/ecological/pollination.html |title=Pollination |publisher=Trees for Life |access-date=14 November 2017 |archive-date=6 October 2014 |archive-url=https://web.archive.org/web/20141006130745/http://www.treesforlife.org.uk/forest/ecological/pollination.html |url-status=live }}</ref> Trees use a variety of methods of [[seed dispersal]]. Some rely on wind, with winged or plumed seeds. Others rely on animals, for example with edible fruits. Others again eject their seeds (ballistic dispersal), or use gravity so that seeds fall and sometimes roll.<ref name="NathanSeidler2006">{{cite journal |last1=Nathan |first1=Ran |author1-link=Ran Nathan |last2=Seidler |first2=Tristram G. |author-link2=Tristram G.
