Editing Nature reserve (section)

=== Brazil ===
In Brazil, nature reserves are classified by the [[National System of Nature Conservation Units]] as [[Ecological station (Brazil)|ecological stations]] ({{langx|pt|estações ecológicas}}) or [[biological reserve (Brazil)|biological reserves]] ({{langx|pt|reservas biológicas}}). Their main objectives are preserving fauna and flora and other natural attributes, excluding direct human interference. Visits are allowed only with permission, and only for educational or scientific purposes. Changes to the ecosystems in both types of reserve are allowed to restore and preserve the natural balance, biological diversity and natural ecological processes.<ref name=ICMBio>{{citation|url=http://www.icmbio.gov.br/portal/unidadesdeconservacao/categorias|language=pt|title=Categorias|publisher=[[ICMBio]]|access-date=16 July 2016|archive-url=https://web.archive.org/web/20160713092433/http://www.icmbio.gov.br/portal/unidadesdeconservacao/categorias|archive-date=13 July 2016|url-status=live}}</ref> Ecological stations are also allowed to change the environment within strictly defined limits (e.g. affecting no more than three percent of the area or {{convert|1500|ha}}, whichever is less) for the purpose of scientific research.<ref>{{citation|ref={{harvid|Ecological Station – ISA}}|title=Ecological Station|publisher=ISA: Instituto Socioambiental|url=http://uc.socioambiental.org/en/prote%C3%A7%C3%A3o-integral/ecological-station/|access-date=30 April 2016|archive-url=https://web.archive.org/web/20181023080037/https://uc.socioambiental.org/en/prote%C3%A7%C3%A3o-integral/ecological-station/|archive-date=23 October 2018|url-status=dead}}</ref>
A [[Wildlife reserve (Brazil)|wildlife reserve in Brazil]] is also protected, and hunting is not allowed, but products and by-products from research may be sold.<ref name=ICMBio/>

Wildlife refuges in Brazil have as their objective the protection of natural flora and fauna where conditions are assured for the existence and reproduction of species or communities of the local flora and the resident or migratory fauna. The refuges can consist of privately owned land, as long as the objectives of the unit are compatible with the landowners' usage of the land and natural resources. Public visits are subject to the conditions and restrictions established by the management plan of the unit and are subject to authorisation by and regulations of the main administrative and scientific research body.<ref>{{Cite web|url=http://uc.socioambiental.org/sites/uc.socioambiental.org/files/snuc_sistema%20nacional%20de%20unidades%20de%20conservacao.pdf|archive-url=https://web.archive.org/web/20130330014401/http://uc.socioambiental.org/sites/uc.socioambiental.org/files/snuc_sistema%20nacional%20de%20unidades%20de%20conservacao.pdf|url-status=dead|title=Brazil 2000.
