Projects
Forest Modeling
The forest gap model FORMIND is an individual-based vegetation model that simulates the growth of forests on the hectare scale. It allows to explore forest dynamics and forest structure including also processes like gap building (falling down of large trees).
More details about FORMIND at www.formind.org
Simulating the carbon stocks and fluxes of tropical rainforests at Mt. Kilimanjaro
Analyzing the carbon fluxes of a tropical forest in Tansania, Africa. We simulated biomass dynamics, forest productivity and carbon fluxes for a sub-montane forest at Mt. Kilimanjaro.
Modelling the dynamics of tropical rainforests in Madagascar under climate change
Simulating the dynamics of lowland tropical forest in a changing world. Analyzing the impact of drought and logging on rainforest structure and dynamics.

Evaluating the impact of selective logging on forest dynamics
Analyzing the mid- and long-term impacts of different management intensities on the dynamic and structure of a species-rich tropical lowland forest of French Guiana. High selective logging intensities prolong the recovery times of ecosystem functions such as biomass and productivity.
Grouping of tree species for modelling species-rich forests
The challenge of considering the high species diversity of tropical forests in forest models is often addressed by grouping species into plant functional types (PFTs). However, the number of PFTs affect the predictions of forest productivity and other carbon fluxes derived from forest simulations.
Remote Sensing
Emissions from the edge of the forest: global forest fragmentation
Deforestation has a correspondingly fatal effect, even for the remaining forest fragments. Vegetation at the edges is exposed to an unfavourable micro-climate: direct solar radiation and higher wind speeds mean that these areas dry out more readily. We analysed the state of tropical forest fragmentation and its impact on the global carbon cycle by using high-resolution remote sensing data. We have discovered that fragmentation of formerly contiguous areas of forest leads to carbon emissions rising by another third.

Press release
We found also similar patterns of fragment sizes in the tropics across all continents. These patterns follow exactly the analytical predictions of percolation theory. In our analysis we show that, beyond the critical point, continental tropical landscapes will in future consist of many more small and isolated forest fragments if deforestation continues as before.

Estimating forest structure from remote sensing
We investigated the potential of lidar and radar data to monitor forest biomass and forest structure and its temporal variations. Forest structure identification can be used to distinguish between different forest stages and different types induced by logging, natural disturbance, or forest management.

More methods regarding forest structure analysis was performed within the HGF Alliance “Remote Sensing and Earth System Dynamics” - improving the understanding and modelling of dynamic processes.
Linking Remote Sensing with Ecological Modeling
An innovative field is the combination of individual-based vegetation models with the latest remote sensing technology. For this purpose, the high degree of detail of the models in combination with the full-coverage measurement of the earth is used to determine the different ecosystem functions.
Estimating forest biomass and carbon fluxes from remote sensing
Forest models can help to better interpret remote sensing data. The linkage of models with remote sensing (e.g., lidar) allow to develop robust relationships between remote sensing metrics and forest variables like biomass. This can be done for local studies as well as for whole continents.

The role of forest structure for biomass and productivity
Future remote sensing missions will have the capability to provide information on forest structure (e.g., from lidar or radar). By linking remote sensing techniques with vegetation modelling, the role of forest structure for ecosystem services of forests can be investigated. This will lead to more accurate assessments of forest biomass and productivity around the globe.
