1761. Uspevanje omorike (Picea omorika (Pančić) Purk.) v generativnem semenskem nasadu Počivalnik pri PostojniSebastian Bambič, Kristjan Jarni, Gregor Božič, Robert Brus, 2020, original scientific article Abstract: Omorika (Picea omorika (Pančić) Purk.) je endemična drevesna vrsta z Balkanskega polotoka, ki dobro uspeva tudi v Sloveniji in bi bila na nekaterih rastiščih v manjših deležih lahko zanimiva alternativa navadni smreki (Picea abies (L.) Karst.). Raziskavo smo opravili v nasadu omorike pod vrhom hriba Počivalnik med Uncem in Postojno. Drevesa so bila posajena leta 1988 in so zdaj v fazi drogovnjaka. Izmerili smo jim prsni premer in ocenili zdravstveno stanje. Izračunali smo deleže dreves različnih zdravstvenih stanj za posamezne provenience in fenotipe, izdelali model nasada, napravili analizo variance in post hoc test. Ugotovili smo, da imajo provenience velik vpliv na vitalnost dreves, ne pa tudi na debelinski prirastek. Vitalnost dreves se prav tako razlikuje med posameznimi fenotipi. Korelacijo med fenotipi in prsnimi premeri smo potrdili pri dveh od petih fenotipov (B; tip 'semidichotomy', C; tip 'serbica'). Vpliv fenotipa na debelinski prirastek je v različnih proveniencah različen. Glede na našo raziskavo bi bil ob morebitni uporabi za Dinarski kras v Sloveniji najprimernejši semenski material provenience Šargan, najprimernejša fenotipa pa C (tip 'serbica') in F (tip 'argentea'), oba sicer najbolj zaželena tudi v hortikulturi.

1762. Close-to-nature forestry - participatory planning and educational outreach : using Forest Development Types (FDT) in communication and learningJ. Bo Larsen, Anders Busse Nielsen, 2011, original scientific article Abstract: Conversion from age-class forestry to close-to-nature forest management calls for new ways to describe and communicate long-term goals for stand development with forest owners, workers and managers, as well as stakeholders. Further, it is crucial to integrate goals and methods of close-to-nature forestry into education and training. In Denmark, Forest Development Types (FDT), illustrated by use of profile diagrams, has proved a useful concept forcommunicating such "novel" long-term goals thus being instrumental in facilitating and supporting dialogue and participation in planning processes. The concept has already been applied to 120,000 ha of state owned forests and used by the municipality of Aarhus - Denmark's second largest city - as part of a participatory planning process in agreeing upon long-term goals for 1,800ha of forest in and adjacent to the city. Further, the concept of forest development types is used as a planning and design tool for forest landscape restoration in teaching at the international master course "Urban Woodland Design and Management" at the University of Copenhagen. Drawing upon experiences gained from these actions, the paper describes and discusses the concept of Forest Development Types as a tool easing social learning between research and practice, promoting public involvement, and facilitating professional learning around close-to-nature forest management at the university level.

1763. Development of close to nature forestry and the role of ProSilva EuropeJean-Philippe Schütz, 2011, professional article Abstract: We present the different facets of close to nature forestry and the reasons for its practical success. They lie in using free natural processes, the so-called biorationalisation, to achieve multi- purpose aims. This vision is fully in line with promoting good governance, achieving optimal habitat conditions and thus to improve biodiversity. This appears to be the right model for multiple use in modern societies. It is also compatible with the current goal of good carbon management.

1764. Economic and ecologic advantages of small scale structured beech close-to nature forest management : the case of group selection systemFranz-Sales Froehlich, 2011, professional article Abstract: The District Forestry of the Duchy of Lauenburg (Schleswig-Holstein) changed silvicultural system in beech forests from "shelterwood with delayed clearance" to "group selection felling" due to economic, political and nature conservation reasons. The comparison of both systems showed advantages of group selection system regarding growth of valuable large diameter trees and higher overall income of about 10%, but small loss of regeneration growth and quality due to the effects of edging. The ecological values are in favour of group selection system due to similarities in forest horizontal structure withold-growth forest.

1765. Pregled jelovih rastišč v SlovenijiIgor Dakskobler, Aleksander Marinšek, 2009, review article Abstract: Članek vsebuje pregled jelovih rastišč na ozemlju Slovenije. Našteli in kratko opisali smo deset jelovih (bukovo-jelovih, smrekovo-jelovih) združb. Nekatere uspevajo na svežih do vlažnih, nevtrofilnih ali acidofilnih rastiščih podgorskega in gorskega pasu (Galio-Abietetum, Bazzanio-Abietetum, Polysticho setiferi-Abietetum), druge na zelo skalnatih karbonatnih ali silikatnih rastiščih z inicialnimi tlemi (npr. Ribeso alpini-Piceetum, Neckero-Abietetum, Calamagrostio-Abietetum, Paraleucobryo-Abietetum). Jelka ima pomembno ekološko, biotopsko in gospodarsko vlogo v nekaterih bukovih (jelovo-bukovih) združbah (npr. Omphalodo-Fagetum, Homogyno sylvestris-Fagetum, Anemono-Fagetum). Uspeva v večini smrekovih združb, v macesnovju (Rhodothamno-Laricetum) in alpskem ruševju (Rhododendro hirsuti-Pinetum prostratae = Rhodothamno-Rhododendretum hirusti).
