A project that aims to compile and synthesize the existing knowledge on the structure and diversity of neotropical tree communities and the functional traits of their species. Currently, the project mainly contains information from the forests and shrublands of eastern South America, including the Atlantic Forest, Cerrado, Caatinga and Pantanal domains (i.e. extra-Amazonian neotropical domains). It includes surveys of all vegetation types, successional stages and sampling methods. The database is currently in version 4.0. Read More
IMPORTANT NOTE: This project is no longer funded and it is maintained in the free time of its coordinators. The database is currently being used by many projects and has received an increasing number of new requests, a number well above what the coordinators can manage. Therefore, from May 2021 the access to the database is suspended indefinitely. Exceptions can be made for species trait data, but replies to data requests may be delayed (weeks or more). Priority is given to proposals that can improve the quality of the database instead of just using it.
So far, TreeCo is composed by two main bodies of information:
Figure 1. The current geographical extent covered by TreeCo (top left), the distribution of all the quantitative vegetation inventories stored in the database (top right), the inventories with species abundance data already entered in the database (bottom left), and the inventories with information on Tree Above-ground Biomass (AGB), excluding data from state forest inventories (bottom right). Thick lines present the official limits of Latin America, while the grey lines define the Brazilian states. The number of inventories with geographical coordinates (N) is given for each panel.
The file below provides an example of how some TreeCo site, abundance and trait data are stored and the details on each of the information. This may be used to evaluate if TreeCo has the information you are looking for and how it is organized if you want to contribute data: TreeCo_tables_and_descriptions
TreeCo is available upon reasonable request from researchers interested in using the database for scientific purposes. We may share all the data available as long as there is no overlap with ongoing projects, and if references and funding sources are properly cited. We are also more prone to share TreeCo data with researchers willing to give their input on the quantity/quality of the database than only using it. Young and early-career researchers willing to use the database in their grad or post-doc projects are especially welcome, particularly those from institutions in the Global South.
TreeCo coordinators are also open for collaboration on the research topics listed below ('Future research topics'). We are glad to provide lists of references and to share pdf copies of any study we may have. The use of other information stored in the database, such as the species composition, abundance, trait and site information, is also possible. But in this case, it may imply the participation of the project coordinators in the investigation and related publications. These decisions are made on a case-by-case basis and they depend on the scale of the study propose and the actual participation of coordinators in the project.
To speed up the sharing process of TreeCo data, please read carefully the information above and provide with your request the title and goals of the project, the name of people, institutions, grad schools, and funders involved. For requesting access to TreeCo species trait data, please also provide a list of the plant taxa and traits.
The main scientific questions we want to answer using TreeCo are related to the following topics:
We are grateful for the hundreds of researchers, students and technicians that performed fieldwork, species identification and data analysis that resulted in the published and unpublished inventories that are included in TreeCo.
We also thank all people that have directly contributed to surveys and species data compilation, namely Gregory Pitta, Danilo Mori, Luiz Magnago, Markus Gastauer, Carolina Bello, Renato Toledo, Natália Targhetta and Geison Castro.
We are also greatly in debt with the researchers that provided their (un)published tree data: André Amorim, Andréia A. Rezende, Bruno R. Ribeiro, João A. Meira-Neto, João L.F. Batista, Marcelo Pansonato, Márcia C.M. Marques, Maria T.Z. Toniato, Maira C. Pardgurschi, Mario J. Marques-Azevedo, Markus Gastauer, Ricardo R. Rodrigues, Robson L. Capretz and Victor P. Zwiener.
TreeCo database was funded by the São Paulo Research Foundation (FAPESP) grant 2013/08722-5 and by the European Union’s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement no. 795114.
The forest inventories compiled by TreeCo were funded by many different agencies, such as the Coordination for the Improvement of Higher Education Personnel (CAPES), by the National Council for Scientific and Technological Development (CNPQ) and by the many state-specific research funding agencies, such as FAPESP, FAPEMIG, FAPESC, FAPERJ, etc. These agencies funded the scholarships, fieldwork and/or equipment used to conduct these inventories.
We acknowledge some specific funding that resulted in the (un)published data included in TreeCo: São Paulo Research Foundation (FAPESP), grants 1999/08515-0, 1999/09635-0, 2003/12595-7 and 2004/04820-3. Santa Catarina Research Foundation (FAPESC), grant 2017TR1922. Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), grant 312075/2013-8 and 484747/2011-8. US Department of Energy grant DE-FC26-01NT411151 (US Department of Energy).
