About the collections

The Natural History Museum of Denmark is the main museum for natural history in Denmark and is responsible for the management of the national natural history collections, as well as associated research and public outreach.

The many specimens in the collections derive from all over the world, and make up the main part of Danish natural history heritage. The museum’s collections are also amongst the oldest in the world.

Many of the oldest specimens in the collections were collected or acquired due to their beauty, peculiarity or commercial value. But by far the largest part have been collected for scientific use and are part of a global research infrastructure, and in active use on many levels.

Collection-based research

Every year, the museum’s collections are visited by hundreds of researchers from all over the world, who use them in their research. Moreover, hundreds of loans are sent away to researchers around the globe. A loan can consist of anywhere between a single and thousands of specimens.

The collections allow the museum to engage in collection-based research. While the research at the museum depends on the collections, the opposite is also true. As more research is conducted upon the museum’s specimens, their value increases because of the additional associated information deriving from research results.

An extensive cooperation exists between natural history museums across the globe. The collections within them are a gigantic piece of research infrastructure, whose scope (and expenses) rivals that of the CERN facility in Switzerland or the giant telescope arrays in Chile.

Collection and growth

The employees of the museum have been collecting strategically and systematically at home and abroad for almost 400 years, and they continue in the present. Furthermore, the new accessions to the museum collections are supported by donations, exchanges and (at a very limited level) acquisitions of specimens. Therefore, the museum collections constantly grow as an unavoidable consequence of the museum’s task of developing them, in order to keep them representative and relevant.

Because earlier generations made systematic collections of natural history specimens, we have unique opportunities in the present to document changes in our nature over time. Many of the collections within the museum have times series of animals and plants which stretch 200 or 300 years into the past. Each individual specimen supplies a brief window in time of a species or community at a given date, and makes it possible for researchers to “travel in time” and reconstruct the past in relation to the present problematic, which is being studied.

Natural history collections play a major role in our understanding of biodiversity, evolution and population genetics, as well as the environmental consequences of climate changes, use of pesticides, amongst others. For example, the museum’s collections are a physical archive of the changes in our nature and environment, which took place during the Industrialization from the mid-1800’es until the mid-1900’es, continuing up to the present, where we are experiencing the effects og anthropogenic global climate change.

Collecting for the future

It is important to continue collecting strategically, in order to maintain the times series mentioned above. Time and again, natural history collections have turned out to be a fundamental resource in research projects.

We cannot tell which methods and techniques researchers of the future will develop. Therefore, specimens must be collected and preserved carefully and safely along with all possible information about their finding place and surroundings.

Collection-based outreach and exhibits

The collections make it possible for the museum to create exhibits with authentic natural history specimens, which are not otherwise available in similar quality or quantity. Plants, animals, rocks and fossils from the collections are also part of daily public outreach activities, where the museum staff show and tell, allowing visitors to experience natural history up close.

Therefore, the collections have an obvious value with regards to education and outreach to the general public.
