Tropical forests harbour thousands of useful plants that are harvested and used in subsistence economies or traded in local, regional or international markets. The effect on the ecosystem is little known, and the forests resilience is badly understood. Palms are the most useful group of plants in tropical American forests and in this project we study the effect of extraction and trade of palms on forest in the western Amazon, the Andes and the Pacific lowlands. We determine the size of the resource by making palm community studies in the different forest formations and determine the number of species and individuals of all palm species. The genetic structure of useful palm species is studied to determine how much harvesting of the species contributes to genetic erosion of its populations, and whether extraction can be made without harm. We determine how much palms are used for subsistence purposes by carrying out quantitative, ethnobotanical research in different forest types and we also study trade patterns for palm products from local markets to markets that involve export to other countries and continents. Palm populations are managed in various ways from sustainable ones to destructive harvesting; we study different ways in which palms are managed and we will propose sustainable methods to local farmers, local governments, NGOs and other interested parties. Finally we study national level mechanism that governs extraction, trade and commercialization of palm products, to identify positive and negative policies in relation to resilience of ecosystems and use this to propose sustainable policies to the governments. ...

The Amazon Tree Diversity Network is an electronic network of 143 botanists, ecologists and taxonomists that share data and information on tree diversity in the pan-Amazon (Amazonia s.s. and the Guyana Shield). Our drive is to gain a better understanding of the processes that drive (patterns of) alfa- and beta-diversity in the region and, through this knowledge, contribute to better conservation strategies for the region. Currently we work with data from botanical 1-ha plots (and sometimes different sizes), forest inventories, and herbarium collections. In 2003 the work of ATDN resulted the first accurate and robust map of tree alpha-diversity of the Amazon. We unravelled relationships between climate and diversity. The combination of the above results and use of functional groups, successfully tried in some of our Guyana plots, and now also in the Amazon, can perhaps help us to predict the effect of global change in these important and beautiful forests. ...

Brazil will have the honor to host the XXV IUFRO World Congress in 2019, in Curitiba, PR. For the first time this congress will be held in Latin America and, for this reason, offers a unique opportunity for researchers in the region to show the importance of forestry research in promoting sustainable development. The host institutions of the event are the Brazilian Forest Service (SFB) and the Brazilian Agricultural Research Corporation (Embrapa). Other institutions support the event, such as government agencies, universities, research institutions and forestry companies, as well as local tourism entities and Embratur. ...
