Madidi Project Full Dataset

This item contains <strong>version 2.2</strong> of the Madidi Project's full dataset. The zip file contains (1) raw data, which was downloaded from Tropicos (www.tropicos.org) on October 19, 2019; (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; and (5) a miscellaneous collection of additional non-essential information and figures. This item also includes the Data Use Policy for this dataset. 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]], and Gabriel Arellano [[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.

Sebastian Tello（[e-mail]）担任科学主管，Olga Martha Montiel（[e-mail]）担任行政主管。两位主管统筹位于玻利维亚的研究团队的各项活动。密苏里植物园还与其他数据贡献者（目前包括Manuel J. Macía [[e-mail]]与Gabriel Arellano [[e-mail]]）、玻利维亚国家标本馆代表（LPB；Carla Maldonado [[e-mail]]）以及来自各机构的其他密切合作研究者开展协作。如需了解马迪迪项目的组织架构与目标详情，可访问项目官方网站（www.madidiproject.weebly.com）。
