The oldest and largest facility of its type at the University Forestry Enterprise, Křtiny is the Křtiny Arboretum located on the road between the market town of Křtiny and Jedovnice around 20 km to the north of the South Moravian metropolis Brno. It was established in 1928 by August Bayer, a professor at the then Faculty of Forestry at the University of Agriculture in Brno. The arboretum is set in 23 hectares covering meadows along a stream and the adjacent parts of the forest slopes, and also includes a fishpond. As many as a thousand taxa of trees are recorded here, including more than 200 species, hybrids and cultivars of willow which is one of the rarities of this unique collection. The rarest tree that can be seen by students and visitors is the Japanese umbrella-pine (Sciadopitys verticillata) that comes from distant Japan. The arboretum features an educational trail of Native Trees complete with information panels on each tree presented. Its natural beauty is suitably augmented by more than twenty-five wooden statutes and sculptures made by students from the Faculty of Forestry and Wood Technology at Mendel University in Brno during their sculpture symposia. The new peatbog and moorland are interesting additions, as are the outdoor study amphitheatre and the associated leisure and educational trail Praise Be to the Trees, devoted to individual tree species.
The Masaryk Forest University Forestry Enterprise, Křtiny was, in view of the exceptional value of this educational facility, forced into the essential replacement of fencing to secure the Křtiny Arboretum against uninvited visitors and large game animals. Work on its replacement was performed by the UFE Křtiny building centre at the end of 2004 on the basis of a state subsidy to the amount of 1,950,000 CZK from the Ministry of Education of the Czech Republic. The new two-metre-high fence is 2,300 metres in length. In the forest sections (a length of 1,200 metres) this fence is made from wire meshing on concrete fence posts. The front section (of a length of 1,100 metres), designed by renowned landscape architect Professor Ivar Otruba, is constructed of wooden posts on concrete bases, completed with wooden baulks and lathes.
During the course of the year, Křtiny Arboretum is open to the public one day a week – Saturday – throughout the entire vegetation period between its Open Day, held at the end of the month of May, and the beginning of the month of October.
This is the youngest and smallest arboretum (permanent research area) at the University Forestry Enterprise, Křtiny, covering a mere 2.5 hectares. It is located in the Moravian Karst by the Hraniční forest path in the Habrůvka forester’s district in the forests between Habrůvka and Rudice. It is, however, of unique importance as it is the only one of the comparable facilities of its kind in the area to be located in an acidic habitat. These conditions predispose the occurrence of different trees to those found in the Křtiny and Řícmanice arboreta. In view of the fact that Habrůvka Arboretum is still under construction, it is not as yet open to the public and serves merely students and lecturers for study and research purposes.
