== Effects == [[File:Rhino Killings.jpg|thumb|Memorial to rhinos killed by poachers near [[St Lucia Estuary]], South Africa]] {{Further|Species affected by poaching}} The detrimental effects of poaching can include: * [[Defaunation]] of forests: [[predator]]s, [[herbivore]]s and fruit-eating [[vertebrate]]s cannot recover as fast as they are removed from a forest; as their populations decline, the pattern of [[seed predation]] and [[seed dispersal|dispersal]] is altered; tree species with large seeds progressively dominate a forest, while small-seeded plant species become [[Local extinction|locally extinct]].<ref>{{cite journal |last=Redford |first=K. |title=The Empty Forest |journal=BioScience |date=1992 |volume=42 |issue=6 |pages=412–422 |jstor=1311860 |url=http://www.biology.ufl.edu/courses/pcb5356/2011fall/kitajima/Redford1992Biosci.pdf |archive-url=https://web.archive.org/web/20131111203443/http://www.biology.ufl.edu/courses/pcb5356/2011fall/kitajima/Redford1992Biosci.pdf |url-status=dead |archive-date=2013-11-11 |doi=10.2307/1311860 }}</ref> * Reduction of animal populations in the wild and possible extinction.<ref>Harrison, R., Sreekar, R., Brodie, J.
