Editing Reforestation (section)

=== Biodiversity loss ===
Reforesting sometimes results in extensive canopy creation that prevents growth of diverse vegetation in the shadowed areas and generating soil conditions that hamper other types of vegetation. Trees used in some reforesting efforts (for example, ''[[Eucalyptus globulus]]'') tend to extract large amounts of moisture from the soil, preventing the growth of other plants. The [[European Commission]] found that, in terms of environmental services, it is better to avoid [[deforestation]] than to allow for deforestation to subsequently reforest, as the former leads to irreversible effects in terms of [[biodiversity loss]] and [[soil degradation]].<ref>{{cite web|title=Press corner|url=https://ec.europa.eu/commission/presscorner/detail/en/MEMO_08_632|access-date=28 September 2020|website=European Commission – European Commission|language=en}}</ref>

The effects reforestation has on biodiversity is not limited to just other forms of vegetation, it can affect all forms of living organisms all contained in the present ecosystem.<ref>{{Cite journal |last1=Aerts |first1=Raf |last2=Honnay |first2=Olivier |date=2011-11-24 |title=Forest restoration, biodiversity and ecosystem functioning |journal=BMC Ecology |volume=11 |issue=1 |pages=29 |doi=10.1186/1472-6785-11-29 |issn=1472-6785 |pmc=3234175 |pmid=22115365 |doi-access=free |bibcode=2011BMCE...11...29A }}</ref> Due to the major role trees have on ecosystems it is important to better understand components like the ecosystem, waterways, and species present in areas that are being re-planted.&nbsp;Prior research helps limit the depletion of biodiversity which can hinder medicinal discoveries, and alter gene flow in organisms.<ref name="Cunningham 301–317" />

A debated issue in managed reforestation is whether the succeeding forest will have the same [[biodiversity]] as the original forest. If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a [[monoculture]] forest similar to agricultural crops would be the result. However, most reforestation involves the planting of different selections of seedlings taken from the area, often of multiple species.<ref name="kennethmarendefoundation.com">{{cite web |title=Archived copy |url=http://kennethmarendefoundation.com/index.php/reforestation-problem |url-status=dead |archive-url=https://web.archive.org/web/20141111185724/http://kennethmarendefoundation.com/index.php/reforestation-problem |archive-date=2014-11-11 |access-date=2013-03-27}}</ref><ref name="RTR">{{Citation |author1=Goosem, Stephen P |title=Repairing the rainforest |publication-date=2013 |year=2013 |edition=2 |publisher=Wet Tropics Management Authority; [Tarzali, Queensland] : Biotropica Australia |isbn=978-1-921591-66-2 |author2=Tucker, Nigel I.
