The Department of Ecology was established in 1993 and is part of the Institute of Environmental Sciences and Environmental Technology in Faculty 2 Environment and Natural Sciences at BTU.

Research in the Department focuses on the effects of anthropogenic (e.g. climate and land use change) and natural disturbances (e.g. wildfire) on biodiversity, biotic interactions and ecosystem processes in natural, forest and agricultural ecosystems. Major research areas include the provision of ecosystem services, predator-prey interactions, litter decomposition by soil fauna, and biodiversity conservation with a focus on terrestrial invertebrates.

Teaching at the Department focuses on Bachelor's, Master's and PhD courses in the international programme "Environmental and Resource Management" and the German-language programmes "Umweltingenieurwesen" and "Landnutzung und Wasserbewirtschaftung". Courses focus on basic knowledge in ecology and biology (ecology: ecosystems, biotic interactions & nature conservation; biology: soil biology, forensics & parasitology).
