Madidi Project Full Dataset - version 4.1

This item contains version 4.1 of the Madidi Project's full
dataset.
The zip file contains: (1) raw data, which was downloaded from Tropicos
(www.tropicos.org) on September 7 2020; (2) R scripts used to modify,
correct and clean the raw data; (3) clean data that are the output of
the R scripts, and which are the point of departure for most uses of the
Madidi Dataset; (4) additional post-cleaning scripts that obtain some
additional but non-essential information from the clean data (e.g. by
extracting environmental data from rasters); and (5) a miscellaneous
collection of additional non-essential information and figures. This
item also includes the Data Use Policy for these data.
The core dataset of the Madidi Project consists of a network of ~500 forest plots distributed in and around the Madidi National Park in Bolivia. This network contains 50 permanently marked large plots (1-ha), as well as >450 temporary small plots (0.1-ha). Within the large plots, all woody individuals with a dbh ≥10 cm have been mapped, tagged, measured and identified. Some of these plots have also been re-visited and information on mortality, recruitment and growth exists. Within the small plots, all woody individuals with a dbh ≥2.5 cm have been measured and identified. Each plot has some edaphic and topographic information, and some large plots have information on various plant functional traits.

The
Madidi Project is a collaborative research effort to document and study
plant biodiversity in the Amazonia and Tropical Andes of northwestern
Bolivia. The project is currently lead by the Missouri Botanical Garden
(MBG), in collaboration with the Herbario Nacional de Bolivia. The
management of the project is at MBG, where J. Sebastian Tello
([e-mail]) is the scientific director and Olga Martha
Montiel ([e-mail]) is the administrative director.
The directors oversee the activities of a research team based in
Bolivia. MBG works in collaboration with other data contributors
(currently: Manuel J. Macía [[e-mail]], Gabriel Arellano
[[e-mail]] and Beatriz Nieto
[[e-mail]]), with a representative from the Herbario
Nacional de Bolivia (LPB; Carla Maldonado [[e-mail]]),
as well as with other close associated researchers from various
institutions. For more information regarding the organization and
objectives of the Madidi Project, you can visit the project’s website
