A landscape model for quantifying the trade-off between conservation needs and economic constraints in the management of a semi-natural grassland community (2008) Biological Conservation 141 (3), S. 719-732.
DOI: 10.1016/j.biocon.2007.12.017
We present a landscape model to investigate the ecological consequences and costs of different management regimes in semi-natural grasslands. The model integrates dynamic abiotic conditions, management (i.e. disturbance) regime and response of more than 50 characteristic plant and insect species by modelling the dynamics of relevant niche parameters as predictors for species distribution models. We compare our results for exemplary scenarios differing in spatial and temporal scales and exemplary species belonging to different functional groups through several steps of aggregation. Our analysis aims at the question whether an infrequent massive disturbance by rototilling can serve as a less expensive alternative to annual mowing for preserving the characteristic species composition of open dry grasslands in Southern Germany. Rototilling results in a shifting mosaic determining the habitat quality for plant and animal species that may reduce the survival of local or regional populations. For some meadow species as well as the encroaching shrub species, rototilling has a detrimental effect on regional habitat quality. Other species, e.g. weeds and annual pioneers, strongly benefit or show only negligible reaction. Since this is a multi-objective problem, there is a no magic bullet in selecting an optimum scenario of measures. But by visualising the trade-off between ecological consequences and costs, our model is a valuable tool for conservation managers providing a sound scientific basis for management decisions relying on available ecological knowledge. It is also an interesting example for a model describing complex communities in a relatively simple way, simultaneously considering the main driving factors.

Integrated Grid Based Ecological and Economic (INGRID) Landscape Model - A tool to support landscape management decisions (2007) Environmental Modelling & Software 22 (2), S. 177-187.
DOI: 10.1016/j.envsoft.2005.07.016
The aim of the INGRID landscape model is to simulate the ecological effects of management schemes for dry grasslands and to calculate costs in order to serve as decision tool for nature conservation agencies. To predict the local and regional risk of extinction of plants and animals with respect to different management scenarios/disturbance regimes, we apply modelling approaches on different scales and levels of hierarchy. We integrate abiotic and biotic state variables, processes and complex interactions in a spatially explicit way into the INGRID modelling shell. Data and parameters necessary for reliable modelling were determined empirically in a study site in southern Germany. Subsystems of the overall model are empirically parameterised and validated by means of extensive field surveys. The INGRID landscape model is still in development to be customised to administrative application. In this paper we give an overview on the landscape modelling shell and demonstrate the general structure of the INGRID landscape model. Preliminary results are exemplified with respect to habitat modelling, nature conservation evaluation, and economic modelling of two management scenarios. 2005 Elsevier Ltd. All rights reserved.
