Rettet den Regenwald ist eine gemeinnützige Umweltorganisation, die die Lobby - und Informationsarbeit zur Aufklärung über die Abholzung der Regenwälder als einen ihrer Schwerpunkte ansieht. Ihr zweiter Schwerpunkt setzt direkt in den Regenwaldländern an, wo sie den Kauf von Regenwaldflächen, Protestkampagnen der indigenen Bevölkerung und ähnliche Projekte unterstützt. ...

The Amazon Forest Inventory Network is an international network that has been established to understand the biomass and dynamics of Amazonian forests. Since 2000 we have established a systematic framework for long-term monitoring of this region, which holds more biodiversity, water, and vegetation carbon, than any other region of the planet. RAINFOR has worked step-by-step, including partners across the nations of Amazon, taking account of the potentially strong modulating role of environmental variables like soil nutrition, and the need to help develop a new generation of Amazon ecologists. RAINFOR is curently supported by the Andes and Amazon Initiative of the Gordon and Betty Moore Foundation. ... [Information of the supplier]
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. ...

Rainforest Action Network (RAN) works to protect the Earth's rainforests and support the rights of their inhabitants through education, grassroots organizing, and non-violent direct action. RAN accomplishes its mission through dynamic, hard-hitting campaigns that work to bring corporate and governmental policies into alignment with popular support for rainforest conservation. RAN works in alliance with environmental and human rights groups around the world, including indigenous forest communities and non-governmental organizations in rainforest countries. ...

The Forest Ecosystems Research Center (Forschungszentrum Waldökosysteme or FZW) is part of the Forest Faculty of the University of Göttingen and carries out research into structural dynamics and element recycling processes in sylvan ecosystems as well as into the adaptability of forests in the face of environmental change. This includes study of the interaction between the ecosystems and their environment and the new types of forest damage. Last not least, these investigations also lead to an appraisal of commercial feasibility. The aim is to find out under which conditions sustainable forest management is possible. These conditions include natural factors such as climate and soil development as well as human factors such as the use of biomass and atmospheric pollution. Thus the Research Center studies the effects of atmospheric element deposition and forest management on sylvan ecosystems as well as the effects element outflow has on the environment of these ecosystems. An analysis of cause and effect is a condition for establishing critical loads and taking suitable measures for the stabilisation of sylvan ecosystems. Only in this way can detrimental environmental effects - such as on ground water - be avoided and sustainable forest management implemented. The Forest Ecosystems Research Center co-ordinates and integrates a number of different projects on this subject and supports close co-operation with institutions not belonging to the University. Activities include the organisation of conferences and the establishment of contacts with institutes and scientists. ... [Information of the supplier]
“forestknowledge.net” is a website run by forestry experts for forestry experts. We provide guaranteed quality, up-to-date information on forests, man and forest management. “forestknowledge.net” provides condensed, edited information on a wide range of topics regarding both forests and forestry in plain language.“forestknowledge.net” links research institutions, forest managers, forest owner associations and other non-governmental organisations to each other and provides access to experts. The editorial staff of the respective research institutes is responsible for the text content in “forestknowledge.net”. Each editorial office compiles expert information, edits it and then presents it on the web-portal. So called expert advisory boards, which are composed of at least two scientists, depending on the subject, guarantee the quality of the contributions. ... [Information of the supplier]
