Range and habitat

The Hungarian birch mouse was formerly found throughout the Pannonian Basin, among them most of Hungary, Austria, Slovakia, and Serbia. The Transylvanian birch mouse was likely found throughout the Transylvanian Plateau in the past, but its range has likely shrunk due to agriculture. Its full range has not yet been fully established.

In crisis

It was once found throughout Central Europe and Romania, but is now only known from two isolated populations in Hungary and Transylvania in Romania, each of that belongs to its own subspecies. The Transylvanian birch mouse is also threatened by intensive agriculture, as well as overgrazing by sheep. Both populations, that were later classified into this species, were feared to be extinct throughout most of the 20th century until being rediscovered in the 21st century. The Hungarian subspecies was not seen for over 70 years until being rediscovered in 2006, whilst the Transylvanian subspecies was only rediscovered in 2014.
