The Forest Garden was established in 1922 at an area covering one hectare. Its main purpose is to provide students with an opportunity to gain insights into the basics of nursery production, and to enable scientific research. The surrounding Arboretum with over 300 kinds of trees and bushes is of particular value. The Forest Garden is mechanized, with two well-equipped plastic greenhouses used for plant propagation. Decorative trees and bushes for use in urban forestry are also produced here.
The nursery "Dotrscina" was founded in 1953 at an area of 1 hectare. Its characteristic terraced shape places it among the rarities of Croatia. Basically, horticultural plants to be used in urban forestry are produced here.
The nursery "Novi sumski vrt", covering an area of 4 hectares, is located in close vicinity to the Maksimir park-forest. Its main use is the production of horticultural plants and Christmas trees.
The "Zagreb" TRFF is the first and the oldest teaching and research forest facility to have been established at the Forestry faculty. Upon the foundation of the Agricultural and Forestry Faculty in 1919, a need arose for a teaching and research facility where forestry students could conduct their practical work. For this reason, as early as in 1921, a 140- hectare Maksimir estate was bought from the Zagreb bishopric by the state, soon followed by the purchase of a 160-hectare Mokrice lug forest, and a 90-hectare Sasinovecki lug, both located near Sesvete. For many long years, these facilities were the only ones where the forestry students of the Agricultural and Forestry Faculty did their practical work.
Today, the Zagreb TRFF consists of two more facilities: Dotrscina, with an area of 179 hectares, and Sljeme, with 386 hectares. In terms of hectares, this is the largest facility. Its spatial distribution is of great interest, as it comprises all the most important forest ecosystems in Croatia. Thus, associations of European black alder and dogwood (Frangulo- Alnetum glutinosae Raus 1968) and of Pedunculate oak and common hornbeam (Carpino betuli-Quercetum roboris Raus 1968) are found on the lowest terrains in the Sasinovecki lug forest, Sessile oak and hornbeam forests (Querco-Carpinetum Croaticum Horv. 1938) and mountain beech forests (Lamio orvale- Fagetum sylvaticae Ht. 1938) occur in Maksimir and Dotrscina, and the Pannonian variant of beech and fir association (Abieti- Fagetum panonicum Raus 1969) thrives on Sljeme. Apart from this, the facilities contain a number of successfully raised forest cultures of allochthonous deciduous and coniferous species, which clearly denote the possibility of introducing these species into the local area. Only some of the most successful cultures are listed here: red oak (Quercus rubra), Japanese cedar (Cryptomeria japonica), Oriental plane (Platanus orientalis), Pancic spruce (Picea omorica), and others.
Intensive research activities and student field instruction are carried out in all the facilities. The facilities are characterized by well-preserved forests containing normal or slightly higher values of growing stock. Two modern foresters' homes are currently being built offering ample accommodation for a number of people. Close vicinity to Zagreb makes them highly attractive for both scientists and researchers.
