253 Abstract Acidophytic alpine mat-grass swards are rare in the alpine belt of the predominantly calcareous Southeastern Alps of Slovenia, mostly occurring where limestone is admixed with marlstone or chert. Those for which we were able to make phytosociological relevés can be classified mainly into two syntaxa: Carici curvulae-Nardetum strictae vaccinietosum gaultherioidis and Sieversio-Nardetum strictae vaccinietosum. At slightly lower elevations, in the forest zone of the subalpine plateau Pokljuka, we found similar swards occupying small areas in frost hollows with luvisol on limestone. They include character species of various subalpine-alpine sward and snow bed communities and are classified into the syntaxon Homogyno alpinae-Nardetum scorzoneroidetosum croceae. Izvleček V pretežno karbonatnih Jugovzhodnih Alpah v Sloveniji so kisloljubna travišča v alpinskem pasu redkost in se pojavljajo tam, kjer je apnencu primešan laporovec ali roženec. Tiste, ki smo jih uspeli fitocenološko popisati, lahko uvrstimo predvsem v dva sintaksona: Carici curvulae-Nardetum strictae vaccinietosum gaultherioidis in Sieversio-Nardetum strictae vaccinietosum. Nekoliko nižje, še v gozdnem pasu visokogorske planote Pokljuka, smo podobna travišča našli na majhnih površinah v mraziščnih kotanjah z izpranimi tlemi na apnencu. V njih rastejo značilne vrste različnih subalpinsko-alpinskih združb travišč in snežnih dolinic. Uvrščamo jih v sintakson Homogyno alpinae-Nardetum scorzoneroidetosum croceae.

Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks Introduction Mat-grass (Nardus stricta) is one of the most characteristic species of acidophytic grasslands in Slovenia. This grass is quite widespread in the Slovenian mountains, despite of the predominantly calcareous bedrock of our Alps (with the exception of the Pohorje range) – Figure 1. Phytoso- ciologists classify alpine mat-grass swards into two classes: Nardetea strictae (secondary mat-grass swards in the for- est belt) and Juncetea trifidi (which comprises acidophytic subalpine and alpine swards). Šilc & Čarni (2012) in their conspectus of vegetation syntaxa of Slovenia list several Nardus stricta associations in the lowland and submontane to the lower montane belt of Slovenia, and only one association (Homogyno alpinae- Nardetum strictae), which stands are distributed also in the upper montane belt. Its largest areas are in northern and north-eastern Slovenia, in the Smrekovec Moun- tains, on the Pohorje Massif and Mt. Košenjak. The first phytosociological table of the montane-subalpine-alpine mat-grass swards and pastures for the territory of present- -day Slovenia was published by Aichinger (1933), who classified them into the association Nardetum strictae. He published two tables with relevés from the Austrian and the Slovenian part of the Karawanks and gave a detailed, still valid description of the characteristic species com- bination of these swards, their ecology and syndynamic processes. He pointed out that this community can also develop in calcareous mountains, on specific sites where limestone or dolomite is mixed with marl, claystone or chert, or where the soil is leached or acidified. These com- munities therefore vary considerably in the size of the areas they occupy, and in the alpine belt in particular they can colonise areas as small as a few square metres. Aichinger’s name Nardetum strictae is too general (as it comprises the entire range of mat-grass communities), so phytosociolo- gists who subsequently described several mat-grass domi- nated communities referred to it only as a synonym of the association Sieversio-Nardetum strictae (Grabherr, 1993: 361). This association could include Aichinger’s relevés from Mt. Peca and Ovčji Vrh (Kozjak) in the alpine belt (1940 m – 2050 m) – Table 35 on page 141 (Aichinger, ibid.). On the other hand, according to the current clas- sification some of his relevés from the montane-subalpine belt (Table 33 on page 134) probably belong to the as- sociation Homogyno alpinae-Nardetum strictae, which is documented with relevés and a table from the Pohorje Massif (Kaligarič & Škornik, 2002), Kozjak, Smrekovec and Košenjak (Škornik et al., 2006). Tone Wraber was the first to identify another type of acidophytic alpine sward on Jarečica under Mt. Mangart, which was dominated by mat-grass and Carex curvula. The latter is very rare in Slo- venia, occurring only under Mt. Mangart and on the upper edge of the Kriška Stena rockface to the northwest of Mt. Križ (Wraber & Skoberne, 1989: 88). Wraber named the community Curvuletum, emphasising that it was differ- ent from the eponymous community in the Central Alps and could be its southeastern-Alpine variety (geographical variant). He also listed its most frequent species (Wraber, 1983: 121, see also Dobravec, 1993: 48). At the beginning of the 21st century he aimed to study this community in more detail with Boštjan Surina and analyse their phyto- sociological relevés, but was stopped by his untimely death in 2010. Without his idea, which he had passed on to the youngest of the authors, and without his relevés, we would not have been able to write this article. He is therefore one of the authors of this article, although he can no longer participate in the analyses. Between 2005 and 2021, we made additional relevés of acidophytic subalpine-alpine swards on Jarečica and elsewhere in the Julian Alps and Figure 1: Distribution of Nardus stricta in Slovenia (source: FloVegSi database).

Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks the Karawanks (Figure 2). We processed them together with the relevés of Tone Wraber (kept at Wraber’s library at the Botanical Garden of the University of Ljubljana), using ordination and hierarchical classification methods. Our findings are presented below. Methods Acidophytic subalpine-alpine mat-grass swards in the Ju- lian Alps and partly in the western and eastern Karawanks (Figure 2), were surveyed applying the Central-European phytosociological method (Braun-Blanquet, 1964). We entered 91 relevés into the FloVegSi database (T. Seliškar et al., 2003). The releves were made between 1983 and 2020, mostly from the end of the June to the first part of August. The plot size was 5 to 30 m2, included were also mosses and lichens. The relevés were arranged into tables using hierarchical classification and ordination methods. We transformed the combined cover-abundance values into ordinal scale (1–9) according to van der Maarel (1979). Numerical comparisons were performed using the program package SYN-TAX 2000 (Podani, 2001) and Canoco software (Šmilauer & Lepš, 2014). The rele- vés were compared by means of “(unweighted) average linkage method” – UPGMA, using Wishart’s similarity ratio, and detrended correspondence analysis (DCA). For estimating the general environmental affinities of the relevés, indicator values (co-variables) for vascular plants (L – light, R – soil reaction, T – temperature, N – nut- rients, U – humidity, C – continentality) were assigned according to Pignatti (2005) and passively projected into the ordination biplot. The environmental value in a relevé (EVw) was estimated as a weighted average of the indica- tor values of all species present, using their abundances as weights (Lepš & Šmilauer, 2003). The identified communities were classified into a syn- taxonomic system comparing them to similar commu- nities in Slovenia (Kaligarič & Škornik, 2002, Škornik et al., 2006), Austria (Aichinger, 1933, Ellmauer, 1993, Grabherr, 1993), Friuli Venezia Giulia (Poldini & Oriolo, 1997), the Eastern Alps (Lüth et al., 2011) and the Dolo- mites (E. & S. Pignatti, 2014, 2016). The nomenclatural source for the names of vascular plants is the Mala flora Slovenije (Martinčič et al., 2007) and the FloVegSi database. The nomenclatural source for the names of mosses is Hodgetts et al. (2020), and Sup- pan et al. (2000) for the names of lichens. Mosses in some of the relevés were determined by Andrej Martinčič. Cer- tain lichen taxa were determined only to the rank of ge- nus. For the names of syntaxa we follow Ellmauer (1993), Grabherr (1993), Theurillat (2004), Šilc & Čarni (2012), and Mucina et al. (2016). In the classification of species into phytosociological groups (groups of diagnostic spe- cies) we mainly refer to the Flora alpina (Aeschimann et al., 2004a,b). The geographical coordinates of relevés were determined according to the Slovenian geographic coordinate system D 48 (zone 5) based on Gauss-Krü- ger projection and the Bessel ellipsoid using GPS receiver Garmin Vista HCx. The geological bedrock in the study area is mainly lime- stone or dolomite limestone, interlayered with marlstone, claystone and chert (Buser, 2009). The studied communi- ties occur mainly on dystric brown soil or dystric ranker (Vidic et al., 2015). The climate is montane, with mean annual precipitation of 2000 mm to 3000 mm (Zupančič, 1998) and mean annual air temperature of +2 ºC to -2 ºC (Cegnar, 1998). The amount of snowfall and snow cover duration have varied considerably in recent years, with generally milder winters, warmer summers and shorter average periods of snow cover than in the past, as can be observed from long-term annual averages. The growing season usually lasts from June to September (October). Results Hierarchical classification of 72 relevés and ordination of 91 relevés of acidophytic alpine mat-grass swards Based on the results in Figure 3 we arranged 71 relevés into three tables. Relevé 4 in Figure 3 (species-rich mon- tane sward under Planja above the Učja Valley) was not included in any of the tables and probably does not be- long to the association Nardetum strictae s. lat. Table 1 comprises relevés clustered on the left side of the den- drogram (Figure 3), except for the relevés that stand out in the middle of the dendrogram. Based on their species composition these relevés were classified into the associa- tion Sieversio-Nardetum strictae (SmNs in Figure 4). Table 2 comprises relevés from the right side of the dendrogram (Figure 3), with the exception of relevé 4. Most of the relevés were made on Jarečica under Mt. Mangart. In the main, Nardus stricta and Carex curvula have the highest mean coverage here, so these relevés are classified into the association Carici curvulae-Nardetum (CcNsVg in Figure 4). Table 3 comprises relevés that stand out in the middle of the dendrogram (Figure 3); some of them are still assigned to the association Sieversio-Nardetum (SmNs in Figure 4), but four relevés are classified into the asso- ciation Eriophoro angustifolii-Nardetum (EaNs in Figure 4). Table 4 comprises relevés from the subalpine belt and secondary sites in the forest belt (Homogyno alpinae-Nar- detum strictae), which were compared with other relevés using ordination – relevés HaNsSc in Figure 4. 21/2 • 2022, 253–295 256 Dakskobler et al.

Association Sieversio montanae-Nardetum strictae This association comprises subalpine-alpine mat-grass dominated swards (Grabherr, 1993; Lüth et al., 2011). Its diagnostic species are character species of the alliance Nar- dion strictae: Ajuga pyramidalis, Diphasiastrum alpinum (Lycopodium alpinum), Pseudorchis albida, Campanula barbata, Geum montanum (Sieversia montana), Ranun- culus villarsii, Agrostis capillaris, Carex pallescens, Gna- phalium sylvaticum (Omalotheca sylvatica), Scorzoneroides helvetica (Leontodon helveticus), Nardus stricta, Trifolium repens, Veratrum album. The dominant and constant spe- cies in this association include Carex sempervirens, Agrostis 21/2 • 2022, 253–295 257 Dakskobler et al. Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks rupestris, Anthoxanthum odoratum agg., Helictotrichon ver- sicolor (Avenula versicolor), Festuca nigrescens, Hieracium lactucella, H. pilosella, Homogyne alpina, Potentilla aurea, P. erecta and Vaccinium myrtillus. According to Poldini & Oriolo (1997) its diagnostic species are Scorzoneroides helvetica (Leontodon helveticus), Arnica montana, Geum montanum, Nardus stricta, Campanula barbata, Pseuodor- chis albida and Pulsatilla alpina subsp. austriaca. These authors distinguish between the altimontane, typical and subalpine forms, and the successional stage overgrown by shrubs. Lüth et al. (2011) distinguish four subasso- ciations: typicum, vaccinietosum, trifolietosum pratensis and seslerietosum albicantis. E. Pignatti & S. Pignatti (2014, 2016) use the name Geo montani-Nardetum and identify Nardus stricta, Festuca nigrescens and Carex pallescens as character species of the association. Our stands (Table 1) include most of the listed species with some exceptions, such as Campanula barbata and Gentiana acaulis (G. kochiana). The diagnostic species are Nardus stricta, Festuca nigrescens, Luzula expectata, Carex sempervirens and Geum montanum. The eastern-Alpine species Astrantia bavarica is the geographical differen- tial species. The relevés were made in the Tolmin-Bohinj mountains: under Tolminski Kuk, Dol under Kaluder; in the Trigrav Mountains: Kreda, mountain pasture Tosc, Cesar above Konjska Planina, Čisti vrh, Plazijanski Vršac; in the ridge of the Loška Stena: Plešivec, Spodnji Lepoč; in the Mangart group on Mangart Saddle and in Planje; in the Jalovec group: on Sleme; in the Škrlatica group: Na Jezerih (Na Gruntu) above Bivouac II; in the west- ern Karawanks under Stol, Potoški Stol (Figure 5), on Vajnež Saddle in the ridge of Belščica, and on Mt. Peca in the eastern Karawanks, at elevations between 1690 m (Spodnji Lepoč) and 2180 m a.s.l. (Plešivec in the ridge of Loška Stena). In the ordination diagram (Figure 4) the relevé from Plešivec (SmNs23) stands out significantly from other relevés of this association. The reason is the rich moss layer, which was not observed in most of the other relevés. With a few exceptions (under Mt. Man- gart) these swards occupy small areas, often in contact with swards on calcareous bedrock or with dwarf pine; most of them are used for grazing of small ruminants. The most common parent material is limestone mixed with marlstone, in places with chert, the soil is dystric. Partly, these swards are being overgrown by dwarf pine (Rhodothamno-Pinetum mugo) or by the Siberian juniper community (Rhodothamno-Juniperetum alpinae). Accord- ing to the division of the association Sieversio-Nardetum into four subassociations (Lüth et al., 2011) the stands in Table 1 can be classified into the syntaxon Siversio mon- tanae-Nardetum strictae vaccinietosum. Differential species of the subassociation are Vaccinium gaultherioides, V. myr- tillus, V. vitis-idaea and Anthoxanthum nipponicum. In terms of ecology, the stands of the association Siever- sio-Nardetum in the subalpine-alpine belt of the Slovenian Alps take the central position (Figure 4). Compared to physiognomically similar stands of the association Ho- mogyno-Nardetum they overgrow sites on more acid and nutrient-poor soils at higher elevations. The pronounced temperature gradient in Figure 4, which is probably re- lated to elevation, indicates that the stands of the associa- tion Sieversio-Nardetum occur on relatively warmer sites than the stands of the syntaxon Carici curvulae-Nardetum vaccinietosum. Association Carici curvulae-Nardetum strictae Grabherr (1993) reports three Carex curvula-dominated associations for Austria, which could correspond to the stands on Jarečica: Caricetum curvulae (character species Oreochloa disticha, Pedicularis kerneri, Veronica bellidioi- des), Loiseleurio-Caricetum curvulae (diagnostic species Loiseleuria procumbens, Vaccinium gaultherioides, Empe- trum hermaphroditum, Vaccinium vitis-idaea, partly also Avenella flexuosa, Carex sempervirens, Vaccinium myrtillus) and Carici curvulae-Nardetum (diagnostic species: Nardus stricta, Avenella flexuosa, Carex sempervirens, Arnica mon- tana, Campanula barbata, Gentiana acaulis). Most of the relevés in Table 2 are from Jarečica, an ex- tensive grassland plain under the southwestern wall of Mt. Mangart (Figure 6), some are from other localities un- der Mt. Mangart and one relevé is from the ridge of the Loška Stena (Konjsko Sedlo under Bedinji Vrh). Carex cur- vula was found only on Jarečica and on one relevé under Mali Vrh nearby. Its other known locality in Slovenia is north of Mt. Križ (2410 m) and south of height point 2403 Figure 5: Stand of the association Sieversio-Nardetum, Potoški Stol in the western Karawanks.

Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks m (Vrh Križa), to the east of the upper fringe of the Kriška Stena rockface, on a small patch of grass on a distinctly karstified terrain at the elevation of 2300 m, in the stand of the association Potentillo dubiae-Homogynetum discoloris (T. Wraber, 1969: 81, see also Dobravec, 1993) – Figure 7. In these relevés Carex curvula and Nardus stricta charac- teristically dominate in medium coverage, with either of them absent from only a few of the relevés. This is one of the characteristics of the stands of the association Carici curvulae-Nardetum. Some of the diagnostic species of this association, e.g. Campanula barbata, Gentiana acaulis, Avenella flexuosa, are absent from our relevés, as well as certain constant companions like Phyteuma hemisphae- ricum, Ligusticum mutellina. On the other hand, several character species of the association Loiseleurio-Caricetum curvulae, in particular Vaccinium gaultherioides and V. vi- tis-idaea, are frequent and abundant. Loiseleuria procum- bens is very rare and occurs in only one relevé. Taking into account the dominant species our relevés therefore cannot be classified into this association. This conclusion is further supported by our comparison with the stands of this association in Friuli (Poldini & Oriolo, 1997.), in which Loiseleuria procumbens has the constancy value of 100% and medium coverage value of 4, whereas Nar- dus stricta is absent. However, the compared stands have many species in common with our relevés, in addition to Carex curvula also Vaccinium gaultherioides, V. myrtillus, V. vitis-idaea, Scorzoneroides helvetica (Leontodon helveti- cus), Hieracium alpinum, Helictotrichon versicolor (Avena versicolor), Juncus trifidus, Potentilla aurea, Homogyne alpina, Solidago virgaurea subsp. minuta, Anthoxanthum odoratum agg., Agrostis rupestris, Salix retusa, Selaginella selaginoides, Rhinanthus glacialis, Euphrasia minima, E. picta, Carex sempervirens, Polygonum viviparum, Luzula alpinopilosa, Cladonia arbuscula, Campanula scheuchzeri, Homogyne discolor, Arnica montana, Soldanella pusilla and Poa alpina. In addition, Nardus stricta occurs only in two relevés of the association Caricetum curvulae from the Dolomites (E. Pignatti & S. Pignatti, 2014, 2016). In terms of their floristic composition the acidophytic al- pine swards on Jarečica are therefore transitional between swards from associations Carici curvulae-Nardetum and Loiseleurio-Caricetum curvulae. This transition is indi- cated by Vaccinium gaultherioides, which has the highest medium coverage there, together with Nardus stricta and Carex curvula. Based on the dominant species the stands in Table 2 are classified into the new subassociation Car- ici curvulae-Nardetum strictae vaccinietosum gaultherioidis (Figure 8). Its nomenclatural type, holotypus, is relevé 13 in Table 2. Differential species of the subassociation are Vaccinium gaultherioides, V. vitis-idaea, Helictotrichon ver- sicolor, Juncus trifidus, Luzula alpina, Juncus jacquinii and Hieracium alpinum. The elevation of the localities ranges from 1930 m to 2160 m, the parent material is limestone, mixed with marlstone and chert, the soil is dystric (Fig- ure 9). Expositions are mostly NW, W and SW, with in- clinations of 0 to 20º. The stands on Jarečica are closed, Figure 6: Jarečice under Mangart, stands of tha subassociation Carici curvulae-Nardetum vaccinietosum gaultherioidis. Photo: I. Dakskobler.

Similarly, other small localities of this subassociation are also grazed. Compared to other Nardus stricta-dominated communi- ties in the subalpine and alpine belt of the Slovenian Alps, the stands of the new subassociation (CcNsVg in Figure 4) occurs at the highest elevation, on the most acidic and nutrient-poor soil.

Relevés 1–4 in Table 3, all of them are from Spodnji Lepoč above the Bala valley, can be classified into the association Eriophoro angustifolii-Nardetum strictae, because they are a succes- sional stage in the overgrowing of a wetland, a fen that Figure 8: Stand of the subassociation Carici curvulae-Nardetum vaccinietosum gaultherioidis.

Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks lium it comprises two other species characteristic of fens: Calliergonella lindbergii and Carex canescens. As this is the only relevé for this community, relevé 5 can be assigned to the provisional subassociation Sieversio-Nardetum stric- tae caricetosum canescentis nom. prov., as a special succes- sional stage at the contact of fen and acidophytic alpine sward. The results of the DCA analysis (Figure 4) also indicate high soil moisture of the sites compared to other Nardus stricta-dominated communities. Indicator values suggest that the soil on these sites is more nutrient-rich, less acidic, while the sites have comparably poorer light conditions. This can be partly attributed to the position of Spodnji Lepoč in a hollow surrounded by higher slopes. Other relevés are from the mountain pasture Zgornji Viševnik in the Triglav mountains, Visoki Kurji Vrh in the western Karawanks, Breginjski Stol, Nemške Glave and the summit area of Tosc. Despite the absence of Geum montanum they are provisionally still classified into the association Sieversio-Nardetum strictae, where they be- long in terms of the elevation zone. The most distinct rel- evé is from the summit area of Tosc, 2215 m (the highest elevation of our relevés), which is differentiated by species from alliances Caricion firmae and Arabidion caeruleae (SmNs7 – Figure 4). Acidophytic subalpine mat-grass swards on the Alp Klek and its surroundings (Pokljuka plateau, the Triglav Mountains) Table 4 comprises relevés of acidophytic matt-grass swards from Alp Klek and its vicinity (HaNsSc in Figure 4). We discussed these swards in past (Dakskobler et al., 2010), when we published only two relevés and classified them into the association Homogyno alpinae-Nardetum stric- tae. Ellmauer (1993: 414–415) classifies into this asso- ciation acidophytic mat-grass (Nardus stricta) swards and pastures in the upper montane and lower subalpine belt, which comprise both species from the alliance Nardion (Caricetalia curvulae, Juncetea trifidi) and species from the alliance Violion caninae (Nardetalia strictae, Nardetea strictae), with character species of the order Nardetalia dominating over character species of the order Caricetalia curvulae. The potential natural vegetation of these sites is mixed beech-fir-spruce or spruce forest, which indi- cates that these grasslands are still in the forest zone and developed here after the forest was cleared. The species shared with mat-grass communities from the submontane and lower montane belt (Polygalo-Nardetum and others) include Briza media, Carex pallescens, C. pilulifera, Ga- lium pumilum, Hieracium pilosella, Veronica officinalis and other species, and the species shared with acidophytic subalpine swards from the alliance Nardion are Cam- panula scheuchzeri, Homogyne alpina, Potentilla aurea and Poa alpina. Species such as Crepis aurea, Poa alpina and Phleum rhaeticum link these stands to montane pasture communities from the alliance Poion alpinae. According to Poldini & Oriolo (1997) the differential species of the association Homogyno-Nardetum are Poa alpina, Cam- panula sceheuchzeri and Phleum rhaeticum. Kaligarič & Škornik (2002) and Škornik et al. (2006) list the follow- ing character and differential species of this association: Solidago virgaurea, Veratrum album subsp. album, Homo- gyne alpina, Hypochoeris uniflora, Gentiana pannonica and Potentilla aurea. Relevés from Klek have many species in common with the stands of the association Homogyno alpinae- Nardetum strictae from north-eastern Slovenia and Fri- uli. We identified Nardus stricta, Festuca nigrescens, Gen- tiana pannonica, Luzula expectata and Homogyne alpina as the diagnostic species of the association. Poa alpina, Campanula scheuchzeri and Veratrum album also occur in these stands, whereas Hypochoeris uniflora is absent. Scorzoneroides crocea, Carex montana, Soldanella alpina, Salix retusa and Homogyne discolor (differential species of the subassociation) discriminate these stands against the stands from north-eastern Slovenia and Friuli, to a lesser extent also Centaurea nervosa and Diphasiastrum alpinum as well as certain character species of the class Elyno-Seslerietea (Polygonum viviparum, Thymus praecox subsp. polytrichus, Polygala alpestris, Selaginella selaginoi- des and others). The swards are mostly secondary, still in the subalpine spruce and spruce-larch forest zone. They have a unique ecology, with most of the relevés made in a frost hollow, on dolomite-limestone bedrock with luvi- sol (leached soil), where a small area features a mosaic of diverse subalpine communities (Dakskobler et al., 2010). The species composition is subject to active grazing, in recent years mainly by horses. For now we confirm the original classification and assign all relevés with the excep- tion of relevé 1 in Table 4 (HaNsSc01 in Figure 4) into the association Homogyno alpinae-Nardetum strictae and new subassociation scorzoneroidetosum croceae subass. nov. hoc loco. Its nomenclatural type, holotypus, is relevé 5 in Table 4. Differential species of the new subassociation are Scorzoneroides crocea, Carex montana, Soldanella alpina, Salix retusa and Homogyne discolor. The elevation of the localities ranges from 1500 m to 1535 m, the parent ma- terial is limestone or dolomite limestone, in places mixed with marlstone and chert (Figure 11). Compared to other Nardus stricta-dominated communities in the subalpine- alpine belt these stands occur on relatively nutrient-rich and less acidic soils (Figure 4). The soil type is mainly leached brown soil (luvisol). Expositions are mostly NW, W and SW, but also NE and SE, with inclinations of 0 to 21/2 • 2022, 253–295 261 Dakskobler et al.

In view of the site specifics, they could also be classi- fied into the new association Scorzoneroido croceae-Narde- tum strictae, but this requires a more detailed comparison.

Both types are very similar in appearance. They are distinctly edaphic communities and consequently floristically homoge- neous. The differences in their species composition are in- significant, because many acidophytic species have a large vertical distribution range. This does not apply to Carex curvula subsp. curvula, a south-European montane spe- cies of acidic alpine grasslands, which in Slovenia occurs only on Jarečica under Mt. Mangart and to the northwest of Mt. Križ (east of the upper fringe of the Kriška Stena rockface) in the Škrlatica mountains. Due to their abun- dant presence on the extensive grassland plain of Jarečica under the northwestern rockface of Mt. Mangart the mat-grass stands there (classified into the syntaxon Carici curvulae-Nardetum strictae vaccinietosum gaultherioidis) have a very distinct appearance compared to the stands of another alpine mat-grass community, which is named after Geum montanum – Sieversio-Nardetum. Geum mon- tanum is quite rare in Slovenia (Figure 7), especially in the Julian Alps (the locality in quadrant 9749/4, Črna Prst, is historic, dating from the 19th century (Engel- thaler, 1874), and has no recent confirmations); most of its localities are in the alpine belt, only a few occur below the alpine belt. Also frequent in the stands of both asso- ciations is Homogyne alpina, which gave its name to the mat-grass community in the upper montane and lower subalpine belt, still in the forest zone – Homogyno alpinae- Nardetum. However, denomination under Homogyne al- pina does not sufficiently describe its vertical distribution range and the overall species composition is occasionally quite similar to the species composition of the stands of the association Sieversio-Nardetum. The differential spe- cies are mainly species of cultivated and dry grasslands on calcareous and neutral bedrock, i.e. companion spe- cies that are much more common in the altimontane belt than in the alpine belt. In special ecological conditions, in frost hollows, the acidophytic mat-grass swards occur also on small areas with pure calcareous bedrock, if the soil is leached (see Figure 4; these stands have the least calcifuge Figure 11: Stand of the subassociation Homogyno alpinae-Nardetum scorzoneroidetosum croceae, alp Klek (Planina Klek) on the Pokljuka plateau.

Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks flora). Their species composition features a number of character species of contact communities in the vicinity, and certain species of the alpine belt. One such example are the stands of the new subassociation Homogyno al- pinae-Nardetum scorzoneroidetosum croceae on mountain pasture Klek on the Pokljuka plateau. In addition to natural factors and successional processes grazing of small ruminants and occasionally horses is an- other ecological factor that could, if the density of animals is excessive or if they graze on small areas for too long, lead to degradation and dominance of ruderal species. So far, the surveyed pastures have avoided this process. They comprise many species of conservation importance (Anon., 2002, 2004): protected orchids (Pseudorchis al- bida, Coeloglossum viride, Gymnadenia conopsea), club mosses (Lycopodium annotinum, Huperzia selago, Dipha- siastrum alpinum) as well as Arnica montana and Gentiana pannonica. Red-listed rare or endangered species include Carex curvula, Juncus trifidus, Luzula alpinopilosa, Erioph- orum angustifolium and Scorzoneroides crocea. Povzetek Fitocenološka oznaka kisloljubnih alpinskih travišč v Julijskih Alpah in Karavankah Travišča z volkom (Nardus stricta) so si po zunanjem vide- zu precej podobna, ne glede na njihov izvor. To so izrazito edafske združbe, ki so zato floristično precej homogene. Lahko so drugotne, še na rastiščih nekdanjega gozda, ali primarne, nad zgornjo gozdno mejo ali v mraziščih. Tudi v vrstni sestavi med njimi niso tako velike razlike, saj ima precej kisloljubnih vrst velik višinski razpon uspevanja. To ne velja za upognjeni šaš (Carex curvula subsp. curvula), južnoevropsko montansko vrsto zakisanih alpinskih tra- višč, ki v Sloveniji uspeva le na Jarečici pod Mangartom in severno od gore Križ (vzhodno od zgornjega roba Kriške stene) v pogorju Škrlatice. Zaradi njegovega obilnega po- javljanja na obsežni travnati planjavi Jarečica pod severo- zahodno steno Mangarta so tamkajšnji sestoji volka, uvrš- čamo jih v subasociacijo Carici curvulae-Nardetum strictae vaccinietosum gaultherioidis, tudi po videzu prepoznavno drugačni od sestojev druge alpinske združbe volka, ki se imenuje po gorski sreteni (Geum montanum) – Siever- sio-Nardetum. Gorska sretena je v Sloveniji precej redka (slika 7), kar še posebej velja za Julijske Alpe (nahajališče v kvadrantu 9749/4, Črna prst je zgodovinsko, iz 19. sto- letja (Engel thaler, 1874), novejših potrditev nima) in ima večino nahajališč v alpinskem pasu, posamezna tudi niž- je. V sestojih obeh naštetih asociacij pogosto uspeva tudi alpski planinšček (Homogyne alpina), po katerem se ime- nuje združba volka v zgornjem montanskem in spodnjem subalpinskem pasu, torej še v pasu gozda – Homogyno alpinae-Nardetum. Imenovanje po tej vrsti ne označuje dobro višinskega pasu njenega uspevanja in tudi celotna vrstna sestava ponekod ni zelo različna od vrstne sesta- ve sestojev asociacije Sieversio-Nardetum. Razlikovalne so predvsem vrste gojenih in suhih travišč na karbonatni in nevtralni podlagi, torej spremljevalne vrste, ki jih je v al- timontanskem pasu precej več kot v alpinskem pasu. V posebnih ekoloških razmerah, mraziščih, se kisloljubna travišča na majhnih površinah pojavljajo tudi na čisti kar- bonatni podlagi, v primeru, da so tla izprana (glej sliko 4, ti sestoji imajo najmanj kalcifugno floro). V njihovi vrstni sestavi je precej značilnic stičnih okoliških združb in nekaterih vrst alpinskega pasu. Tak primer so sestoji nove subasociacije Homogyno alpinae-Nardetum scorzone- roidetosum croceae na pl. Klek na Pokljuki. Poleg naravnih dejavnikov in sukcesijskih procesov je pomemben ekološki dejavnik na rastiščih proučenih združb paša drobnice in deloma tudi konj, ki lahko, če je gostota živali prevelika ali se na majhnih površinah zadržujejo predolgo, povzroči degradacijo in prevlado ruderalnih vrst. Za zdaj so pašniki, ki smo jih popisali, pred tem večinoma obvarovani. V njih raste precej nara- vovarstveno pomembnih vrst (Anon., 2002, 2004): za- varovane kukavičevke (Pseudorchis albida, Co eloglossum viride, Gymnadenia conopsea), lisičjakovke (Lycopodium annotinum, Huperzia selago, Diphasiastrum alpinum) ter Arnica montana in Gentiana pannonica. Redke ali ogrožene vrste, ki so na rdečem seznamu, so Carex cur- vula, Juncus trifidus, Luzula alpinopilosa, Eriophorum an- gustifolium, Scorzoneroides crocea.
