SUMMARY: In line with the latest approach to the forestry of Europe, the
need to divide forests and forestland into seed units has been felt in Croatia,
too. At the 9 meeting held on December 9th , J 993, the Commission for scientific-
research work formed a Division Commission, which made a new programe
"Forest seed units in Croatia ". Seed units (regions) for the following nineteen
tree species were formed: Pedunculate oak (Quercus robur L.), Sessile oak
(Quercus petraea Liebl), Evergreen oak (Qercus ilex L.), Pubescent oak
(Quercus pubescens Thuili), Beech (Fagus sylvatica L.), Narrow-leaved ash
(Fraxinus angustifolia Wahl.), White ash (Fraxinus excelsior L.), Black alder
(Alnus glutinosa Garth. (Z.)), White wilow (´Salix alba L.), Black poplar (Popu-
lus nigra L.) with hybrids, Fir (´Abies alba Mill), common spruce (Picea abies
L.(Karsten)), Scots pine (Pinus sylvestris L.), Austrian pine (Pinus nigra
Arnold), Aleppo pine (Pinus halepensis Mill.), Brutian pine fPinus brutia Ten.),
Mediterranean cypress (Cupressus sempervirens L.), allochtonius species:
Weymouth pine (Pinus strobus L.), European larch (l^arix decidua Mill.) and
Douglas fir (Pseudotsuga menziesii Mirb. (Franco)), Maritime pine (Pinus
pinaster Ait.). After the division into seed units, the existing data were included
into the GIS (Geographic Information System). This resulted in accurate maps
for given tree species, and it is exspected that the project will be adopted by
forestry practice. The regulary updated HS database played a very important
role in drawing up these maps. It contains all informations about forest and
forestland in Croatia obtained by regular field measurements.


Key words : division of forests in the Republic of Croatia, seed areas
(districts), zones and units (regions), databases, GIS (Geographic Information
System), maps.
