+  * What do we know about forest growth and biodiversity?
+  * How do forests interact with the climatic system?
 ==== Abstract ====
+Forests play an important role in the global carbon cycle as they store large amounts of carbon.
+Understanding the dynamics of forests is an important issue for ecology and climate change research.
+In this presentation we will give an overview on the knowledge on global forests and their carbon balance.
+We will explain typical methods to model forests and their dynamics.
+Using an individual based forest model (FORMIND) we developed an approach to simulate dynamics of around 410 billion individual trees within 7.8 Mio km² of Amazon forests.
+We combined the simulations with remote sensing observations in order to detect different forest states and structures caused by natural and anthropogenic disturbances.
+Under current conditions, we identified the Amazon rainforest as a carbon sink, gaining 0.56 Gt C per year.
+We found that successional states play an important role for the relations between productivity and biomass.
+Simulated values can be compared to observed local carbon fluxes.
