Dinarska združba rušja je conalna združba Dinarskega gorstva na nadmorskih višinah med 1400 in 1750 m, neposredno nad gozdno mejo, ki jo gradi subalpinski bukov gozd. Na teh rastiščih so težke življenjske razmere, ki jih lahko označimo s kratko vegetacijsko dobo, velikim dnevno-nočnim nihanjem temperature in debelo snežno odejo. Samo poleglo in elastično rušje lahko uspeva na teh rastiščih. Celo posamezne bukve, ki uspevajo tod, so mu fiziognomsko podobni.

Diagnostična kombinacija rastlinskih vrst
Drevesna plast: redke bukve (Fagus sylvatica).
Grmovna plast: Daphne mezereum, Juniperus sibirica, Lonicera caerulea, Pinus mugo, Ribes petraeum, Rosa pendulina, Rubus saxatilis, Salix appendiculata, Sorbus chamaemespilus.
Zeliščna plast: Arabis scopoliana, Carex ferruginea, Erica carnea, Geranium sylvaticum, Homogyne sylvestris, Hypericum richleri subsp. grisebachii, Polygonatum verticillatum, Polystichum lonchitis, Ranunculus carinthiacus, Thymus balcanus, Vaccinium vitis-idaea, Veratrum album.
Mahovna plast: Dicranum scoparium.

Združba gradi skoraj neprehoden preplet poleglega rušja, ki dosega višino med dvema in tremi metri. Združba ima pomembno varovalno vlogo, saj varuje nižje ležeča gozdna območja z zadrževanjem vode ter s preprečevanjem talne erozije.

Združbo dinarskega rušja uvrščamo v zvezo Erico-Pinion mugi.

The Dinaric association of dwarf mountain pine (Pinus mugo) is a zonal association of the Dinaric Alps growing at altitudes between 1,550 and 1,750 meters directly above the forest border formed by subalpine beech forest. On these sites, there are severe ecological conditions including a short vegetation period with a high day-night temperature oscillation and thick blankets of snow. Only weather-beaten and flexible dwarf mountain pine can thrive on these sites. The individual beech and larch trees that grow here have a similar appearance.

Diagnostic combination of plant species
Tree layer: Fagus sylvatica (rare).
Shrub layer: Daphne mezereum, Juniperus sibirica, Lonicera caerulea, Pinus mugo, Ribes petraeum, Rosa pendulina, Rubus saxatilis, Salix appendiculata, Sorbus chamaemespilus.
Herb layer: Arabis scopoliana, Carex ferruginea, Erica carnea, Geranium sylvaticum, Homogyne sylvestris, Hypericum richleri subsp. grisebachii, Polygonatum verticillatum, Polystichum lonchitis, Ranunculus carinthiacus, Thymus balcanus, Vaccinium vitis-idaea, Veratrum album.
Moss layer: Dicranum scoparium.

The thick growth of weather-beaten dwarf pines reaching a height of two or three meters that constitute this association is almost impassable. The association plays an important protective role in protecting lower forest areas by retaining moisture and preventing soil erosion.

The Pinetum mugi croaticum is classified in the alliance Erico–Pinion mugi.
