Phytosociological composition and affiliation of forest stands with domination of fir (Abies alba Mill.) in Lika area

Fitocenološko istraživanje sastojina s dominacijom jele na području gospodarskih jedinica ''Crno jezero-Marković rudine'' i ''Škamnica'' provedeno je prema principima standardne Braun-Blanquetove metode, a imalo je za cilj usporediti ih sa srodnim bukovim i bukovo-jelovim šumama hrvatskih Dinarida. Spomenute sastojine s potpunom dominacijom jele u prijašnjim radovima provizorno su opisane pod nazivom Pleurozio-schreberi Abietetum (Pelcer u Cestar i dr. 1977) u montanskom i altimontanskom pojasu velebitskog gorja i prigorja, a najveće površine rasprostiru se na području šumarija Otočac, manjim dijelom i Brinje. S obzirom da je glavna vrsta obična jela, a one dijelom pridolaze u pojasu bukovo-jelovih šuma, u komparativnoj analizi usporedili smo ih s ranijim Pelcerovim istraživanjima, kao i s dinarskim bukovo-jelovim šumama (Omphalodo-Fagetum) u kojima je jedan od edifikatora obična jela. Rezultati obuhvaćaju analitičke tablice i analizu flornog sastava snimljenih sastojina na temelju deset reprezentativnih ploha. Floristički sastav istraživanih sastojina uključuje vrste iz borealnih crnogoričnih šuma (razred Vaccinio-Piceetea i niže jedinice) i veliki broj vrsta iz bukovo-jelovih šuma dinarskog područja (sveza Aremonio-Fagion, red Fagetalia i niže jedinice), ističući prijelazni karakter zajednice između navedenih sintaksonomskih kategorija. S obzirom na heterogen florni sastav i istaknuta odstupanja, za konačno definiranje zajednice potrebno je provesti dodatna istraživanja, posebice na ostalim lokalitetima iznad 700 m nadmorske visine.Phytocoenological research of the stands dominated by fir in the area of econimic units „Crno jezero – Marković rudine“ and „Škamnica“ was conducted pursuant to the standard principles of Braun-Blanquet method, and was aimed to compare them with similar beech and beech-fir forests of Croatian Dinarides. Mentioned stands with total domination of fir in the previous papers were tentatively titled Pleurozio schreberi-Abietetum (Pelcer u Cestar et al. 1977) in montane and alti-montane mountains and hills of Velebit, with the largest areas extending over the area of Otočac forestry, and to the smaller extent over Brinje. Considering that the main type is common fir, and they partly accrue in a zone of beech-fir forests, in the comparative analysis we have compared them with the earlier research conducted by Pelcer, as well as with beech-fir forests of Dinara (Omphalodo-Fagetum) where one of the edificators is common fir. Results include analitycal tables and analysis of floral composition of taken stands based on the ten most representative surfaces. The floral composition of the studied stands includes species from boreal coniferous forests (class Vaccinio-Piceetea and lower units) and a large number of species from beech-fir forests of Dinara area (band Aremonio-Fagion, order Fagetalia and lower units), emphasizing the transitional character of the community between the previously named syntaxonomic categories. Given the heterogeneous floral composition and highligted deviations, for the final definition of community additional research needs to be conducted, especially at other sites at 700 m above the sea leve
