For the spatial modelling, we use empirical models based on field data, to create maps of the distribution, abundance or biomass of species and habitats. We model benthic species, adult and juvenile fish, harbor porpoises and benthic communities on scales ranging from local to Baltic wide. We have a strong emphasis on development and methodology of species distribution modelling, and we use several different modelling techniques, both uni- and multivariate as well as ensemble modelling.
Based on spatial models of species distribution, it is also possible to estimate total abundances or biomasses over larger areas. VALUES is a three year project which aims to map and quantify the production of ecosystem services. The project will result in hands on examples on how quantitative ecology in combination with economical valuation can be used for marine management and planning. Within SAMBAH we modelled distribution and abundance of harbor porpoises in the Baltic Sea in order to estimate the total number of animals as well as their distribution patterns.
