PRODUCTION OF FOREST SEEDLINGS

40 nurseries of  “Hrvatske šume”, covering an area of 424,05 ha produce annually ca 15 million seedlings. The nursery of the Forestry Research Institute Jastrebarsko produces another 1 milijun, amountig totally to 16 million seedlings. Broadleaved seedlings amount to 12,3 million of the total quantity, needleleaved amount to 1,5 million and 2,2 million of forest seedlings are intended to be afforestated in the Karst seaside region.


 
COLLECTING AND IMPROVING OF SEEDS

For the production of forest seedlings “Hrvatske šume” have for 20 needleleaved species totally 90 objects of acknowledged seed stands on the total area of 407 ha, or further 37 objects of selected forest seed on the total area of 943 ha. For the collection of seeds of 18 broadleaved species there are 113 objects of acknowledged seed stands on the total area of 3 731,50 ha, or 129 objects of selected stands for collection of forest seeds on the total area of 12 678 ha. All the objects are under supervision of the expert department of FRI Jastrebarsko. HŠ has a long term contract with the Institute covering the supervision of the seed objects. At the moment, a Rulebook of classification of seed objects is being developed, according to which the seed objects of “Hrvatske šume” will be newly classified.
