Chilean huemul is an endangered species of deer with the population of only ca. 1300 (300 in Argentina, 100 in Chile). Prof. Zygmunt Giżejewski from the Institute’s department of Biodiversity Protection is the only Pole in an international group called Huemul Task Force, which takes advantage of the conservation biology methods successfully implemented in their host institutions, to impede extinction of this species. During his scientific visit in the region of Patagonia, shared by Argentina and Chile, Prof. Giżejewski presented latest results obtained in deer farming in Popielno, which may be used in the reproduction of huemul, its reintroduction to the natural habitat and creation of a bank gene of this species.  At the conference in Coyhaique (Chile) Professor delivered details on such kind of breeding method, together with a video broadcast featuring semen collection with the use of artificial vagina – a method developed in the PAS Research Station in Popielno. Following discussions with the researchers from DeerLab Argentina, a collaboration agreement has been concluded with the objective to launch a centre of huemul breeding in Shoon Park (Argentina), which will contribute to the protection of this endangered species and allow for studies on its still unknown biology.
