The natural history collections of HU-TAF have global significance. It is one of the largest natural history collections among the Central and Eastern European institutions, comprising more than ten million natural history items, including 44,110 primary types. They have value at a European level as they hold the most important reference and historical collections for the whole of the Carpathian Basin, the Balkans, Central and Eastern Asia, which is regularly accessed by visiting international researchers.
In addition, HU-TAF holds important historical collections; many of them are 200–300 years old. They provide ecological and genetic reference data for comparison with more recent material. The best represented areas are the Palaearctic, Oriental and Ethiopian biogeographic regions and in case of soil animals also the tropical part of America.
