Rewilding vs management for biodiversity: Using a demographic forest model to support conservation planning in the Leipzig Floodplain forest

MSc thesis in forest modelling offered at iDiv Rewilding vs management for biodiversity: Using a demographic forest model to support conservation planning in the Leipzig Floodplain forest The Leipzig Floodplain forest has recently gained national and international prominence as a focal area of an intense debate on suitable strategies for protecting forest biodiversity. As forest under multiple protection schemes, the Leipzig Floodplain forest is considered by some as predestined for realizing a comprehensive rewilding strategy. This is in contrast to the existing FFH management plan which provides options for forest management to promote light-demanding characteristic floodplain tree species such as oak and ash. The problem of designing an optimal conservation strategy is aggravated by three anthropogenic drivers that fundamentally change ecological system dynamics: an artificially altered flooding regime, invasive pathogens, and climate change (Wirth et al. 2021). In collaboration with the head of the Leipzig City Forest Department, Andreas Sickert, the MSc thesis will parameterize a forest succession model (Purves et al. 2008, Rüger et al. 2020) for the Leipzig Floodplain forest. The model simulates the dynamics of unevenaged mixed-species forest stands driven by competition for light based on a small set of demographic rates (growth, mortality, recruitment) which can directly be derived from forest inventory data (Purves et al. 2008). Forest inventory data and tree ring data are available from the “Lebendige Luppe” project (UFZ) and Uni Leipzig and allow (at least partially) deriving the effects of groundwater depth, invasive pathogens, forest management, and climate on the demographic rates of the main tree species. The model will be used to explore the following questions to support optimal forest management under uncertainty: (1) What are expected trajectories of forest structure and species composition under the status quo and potential changes of the flooding regime, the prevalence of invasive pathogens, the forest management, and the climate? (2) Which are the best management options to maintain the characteristic hardwood floodplain tree species, especially oak?
