Sažetak
he paper lists biological and ecological features, distribution, use in landscape and economy, as well as forest growth characteristics for selected species of cypress and cedar trees that are the most frequently used in forestry and horticulture. Upon summing up the previously mentioned the following facts were identified: a common cypress tree reaches up to 30 m in height and is a heliophyte. It is a xerophyte species. In our country it can be grown on a scale of areal distribution of olive growing areas. It is grown in horticulture and is intended for forest melioration. Its seed is fire-adapted and hence it is easily restored after a fire. The Arizona cypress reaches from 12 to 15 m in height and it is not demanding in terms of soil. It is suitable for windbreak, forest meliorations and for the purpose of afforestation. The Atlas cedar is a tree that reaches up to 40 meters in height, growing in arid areas and hence it needs huge quantities of light for growth. It is an important conifer from the aspect of melioration. The cedar of Lebanon reaches up to 40 meters in height and grows in arid regions. It is a heliophyte species. From the aspect of melioration it is an important conifer. The Himalayan cedar (Deodar cedar) tree reaches up to 50 meters in height. In our country it is frequently grown in coastal tree nurseries. Moreover, in our country cedar trees are planted almost exclusively as ornamental horticultural species, while they are very scarce primarily in mixed cultures with pine trees, primarily in Istria and seldom also in coastal areas (Musapstan-Zadar) or on the islands. Summing up in general, these promising Mediterranean species need to be used more frequently in karst melioration, burned area restoration, in forestry as economically important species in mixed cultures and even in horticulture.
