DNAmark establishes the basis for applying environmental DNA analysis in biodiversity research and nature management 

Environmental DNA analysis is a sensitive, economic and efficient method to reveal the presence of species in nature via samples from, for instance, sediment, soil, freshwater, seawater and faeces. DNA analyses can also be used for species determination of bulk samples of invertebrates caught in net or pit fall traps and for assessing the stomach content of bloodsucking and carnivorous invertebrates. In such studies DNA is an efficient tool for revealing the presence of rare, invasive and indicator species, determine biodiversity within and between locations as well as access the effects of climate change.

An extensive DNA reference database is however essential for the strength of environmental DNA analysis. The DNAmark project creates the basis for applying environmental DNA analysis in Danish nature management by establishing a DNA reference database for Danish animal, plant and fungi species and by developing methods for applying environmental DNA analysis in prioritising and managing Danish biodiversity.
