It is situated north of Manaus, central Amazon and includes three sub-sites, with undisturbed terra-firme forest (Reserva Ducke), selective logging (ZF-2 Forest Management Station), and forest fragmentation (Biological Dynamics of forest fragments \u2013 BDFFP sites) spread over around 30 x 30 km landscape. Both logging and fragmentation were carried out as controlled experiments to test their effects on biodiversity and ecosystem processes, and thus to outline recommendations for management. The 3 research areas together have 156 permanent monitoring plots, both terrestrial and aquatic, as well as grids of trails for large-scale process monitoring. The information produced has been stored on a public website (https:\/\/ppbio.inpa.gov.br\/repositorio\/dados) where anyone can search data and metadata about the research, as well as the list of publications and all the educational material ( books, identification guides, training course materials) for download.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1999,"yearClosed":null,"relatedSites":null,"siteName":"Anthropic impacts on the tropical forest of central Amazon","shortName":"IAFA","siteType":"Stationary land-based site","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/anthropic-impacts-tropical-forest-central-amazon-brazil_6830.jpg","alt":"Distribution of sub-sites of the IAFA LTER site"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":26,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":2543,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":null,"biome":"rainforest","ecosystemType":[{"label":"Forest","uri":null},{"label":"Rainforest","uri":null}],"eunisHabitat":[{"label":"Woodland, forest and other wooded land (G)","uri":null}],"landforms":null,"geoBonBiome":["Terrestrial"],"geology":"The site is located over the Alter-do-Ch\u00e3o geological formation, of Cretaceous age.","hydrology":"The hydrology if formed by a dense network of streams mostly from first to forth orders, dissecting the terrains and forming a complex undulating topography of plateaus incised by valleys.
