Editing Clearcutting (section)

===Negative impacts===
Clearcutting can have negative impacts, both for humans and local flora and fauna.<ref>[http://www.forestencyclopedia.net/p/p1818 Forest Encyclopedia Network Advantages and disadvantages of clearcutting]</ref> A study from the [[University of Oregon]] found that in certain zones, areas that were clear cut had nearly three times the amount of [[erosion]] due to [[Landslide|slides]]. When the roads required by the clearcutting were factored in, the increase in slide activity appeared to be about 5 times greater compared to nearby forested areas. The roads built for clearcutting interrupt normal surface drainage because the roads are not as permeable as the normal ground cover. The roads also change subsurface water movement due to the redistribution of soil and rock.<ref>{{cite journal |last1=Swanson |first1=F.J. |last2=Dyrness |first2=C.T. |year=1975 |title=Impact of clear-cutting and road construction on soil erosion by landslides in the western Cascade Range, Oregon |journal=Geology |volume=3 |issue=7 |pages=393–396 |publisher=Geological Society of America |doi=10.1130/0091-7613(1975)3<393:IOCARC>2.0.CO;2 |bibcode=1975Geo.....3..393S }}</ref> Clearcutting may lead to increased stream flow during storms, [[loss of habitat]] and species diversity, opportunities for [[Invasive species|invasive and weedy species]], and negative impacts on scenery,<ref>{{cite web |url= http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/apa3316 |title= Woodlot Harvest |first= Toso |last= Bozic |date= September 14, 2009 |publisher= Government of Alberta: Agriculture and Rural Development |access-date=2011-03-07}}</ref> specifically, a growth of contempt by those familiar with the area for the wooded, planet aftermaths,<ref>{{Cite journal|last=Hansis|first=Richard|date=1995|title=The Social Acceptability of Clearcutting in the Pacific Northwest|url=https://www.jstor.org/stable/44126577|journal=Human Organization|volume=54|issue=1|pages=95–101|doi=10.17730/humo.54.1.yj5338v42768002r|jstor=44126577|issn=0018-7259|url-access=subscription}}</ref> as well as a decrease in property values; diminished recreation, hunting, and fishing opportunities.<ref>Foothill Conservancy, Pine Grove, CA (2001).

In [[Temperateness|temperate]] and [[Taiga|boreal]] climates, clearcutting can have an effect on the depth of snow, which is usually greater in a clearcut area than in the forest, due to a lack of [[Interception (water)|interception]] and [[evapotranspiration]]. This results in less [[Frost line|soil frost]], which in combination with higher levels of direct [[sunlight]] results in [[snowmelt]] occurring earlier in the spring and earlier peak runoff.<ref>{{cite journal | last = Ottosson Löfvenius | first = M. |author2=Kluge, M. |author3=Lundmark, T.. | title = Snow and Soil Frost Depth in Two Types of Shelterwood and a Clear cut Area | journal = Scandinavian Journal of Forest Research | volume = 18 | pages = 54–63 | publisher = Taylor & Francis | year = 2003 | issn = 0282-7581 | doi =  10.1080/0891060310002345}}</ref>

The world's rain forests could completely vanish in a hundred years at the current rate of deforestation. Between June 2000 and June 2008, more than {{convert|150,000|sqkm|abbr=on}} of rainforest were cleared in the [[Amazônia Legal|Brazilian Amazon]]. Huge areas of forest have already been lost. For example, only eight to fourteen percent of the [[Atlantic Forest]] in South America now remains.<ref>{{cite web|title=Reforestation|url=http://www.arkive.org/reforestation/|publisher=Arkive|access-date=2013-01-10|archive-url=https://web.archive.org/web/20130302120215/http://www.arkive.org/reforestation/|archive-date=2013-03-02|url-status=dead}}</ref><ref>{{cite web|title=Brazil & the Atlantic Forest|url=http://www.nature.org/ourinitiatives/regions/southamerica/brazil/placesweprotect/atlantic-forest.xml|publisher=The Nature Conservancy|access-date=2016-01-11}}</ref> While deforestation rates have slowed since 2004, [[forest loss]] is expected to continue for the foreseeable future.<ref>[http://news.mongabay.com/2008/0801-amazon.html Future threats to the Amazon rainforest] {{webarchive|url=https://web.archive.org/web/20121101095911/http://news.mongabay.com/2008/0801-amazon.html |date=2012-11-01 }}</ref> Farmers slash and burn large parcels of forest every year to create grazing and croplands, but the forest's nutrient-poor soil often renders the land ill-suited for agriculture, and within a year or two, the farmers move on.<ref>[https://web.archive.org/web/20100509002310/http://environment.nationalgeographic.com/environment/habitats/rainforest-threats National Geographic:rain forest threats ]</ref>
