General Site Description: 

The LTER IAFA site has been running since 1999 and was the first long-term ecological research site in the Amazon. 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 – 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.

Purpose of Site : 

From the outset we have focused on integrated studies with broad spatial replication based on the Ducke Reserve RAPELD model (72 land plots every 1km, 26 aquatic plots, https://ppbio.inpa.gov.br/en/Methods/RAPELD), and incorporating permanent monitoring plots into the selective logging site at ZF2 (12 plots) and the forest fragmentation experiment at the BDPBFF reserves (38 plots in continuous forests and 11 plots in fragments from 1 to 100 ha). The main objective of this site is to understand the effects of anthropogenic impacts on the biodiversity and functioning of the rainforest ecosystem. At the beginning of the project, the focus was on documenting the distribution of biodiversity, its relationships with the environment, and environmental variability, forest responses to the impacts of logging and forest fragmentation. As long-term monitoring continues, we are being able to document and understand the effects of climate change, both on forests undisturbed by direct anthropogenic actions and those that have already suffered from them, and the synergies between direct anthropogenic impacts and climate change.
