Gozd bukve in kresničevja je aconalna gozdna združba, ki uspeva na strmih do zelo strmih osojnih pobočjih v nadmorskih višinah do 900 m, ki so presekana z globokimi jarki. Prevladuje mezoklima gorskega sveta Slovenije: sveža poletja, zmerno hladne zime in dovolj vlage celo vegetacijsko obdobje. Matična podlaga so dolomiti, na njih prevladujejo srednje globoke skeletne rendzine z zelo ugodno obliko humusa. Globlja tla so le ob vznožju pobočij in v širših jarkih, kamor jih iz višjih leg nanaša voda.

Diagnostična kombinacija rastlinskih vrst
Drevesna plast: bukev (Fagus sylvatica), beli javor (Acer pseudoplatanus), črni gaber (Ostrya carpinifolia).
Grmovna plast: Daphne mezereum, Euonymus latifolia, Lonicera alpigena, L. xylosteum, Rosa pendulina.
Zeliščna plast : Actaea spicata, Anemone nemorosa, Aruncus dioicus, Cyclamen purpurascens, Dentaria bulbifera, D. enneaphyllos, Dryopteris filix-mas, Euphorbia amygdaloides, Galium sylvaticum, Helleborus niger subsp. niger, Laserpitium krapfii, Lilium martagon, Melampyrum velebiticum, Mercurialis perennis, Mycelis muralis, Paris quadrifolia, Phyteuma ovatum, Polygonatum multiflorum, Polystichum aculeatum, Prenanthes purpurea, Senecio ovatus.

Na ekstremnih grebenih se lahko po goloseku razvije drugotni gozd črnega gabra in malega jesena.

Mestoma so lepo gojeni enodobni bukovi gozdovi; veliko je tudi panjevcev, posebno v bližini kmečkih naselij.

Gozdno združbo bukve in kresničevja uvrščamo v zvezo Aremonio-Fagion.

The Arunco–Fagetum is an azonal forest association thriving on shady and steep to very steep slopes dissected by deep gullies up to an altitude of 900 meters. This is a mezzo-climate of the mountain region of Slovenia with fresh summers, moderately cold winters, and plenty of precipitation during the vegetation period. The geological material consists of dolomite covered with medium deep to skeletal rendzic Leptosols with well decomposed form of humus. Deeper soils are found only at foot of slopes and in wider gullies where they are deposited by water from higher locations.

Diagnostic combination of plant species
Tree layer: Fagus sylvatica, Acer pseudoplatanus, Ostrya carpinifolia.
Shrub layer: Daphne mezereum, Euonymus latifolia, Lonicera alpigena, L. xylosteum, Rosa pendulina.
Herb layer: Actaea spicata, Anemone nemorosa, Aruncus dioicus, Cyclamen purpurascens, Dentaria bulbifera, D. enneaphyllos, Dryopteris filix–mas, Euphorbia amygdaloides, Galium sylvaticum, Helleborus niger subsp. niger, Laserpitium krapfii, Lilium martagon, Melampyrum velebiticum, Mercurialis perennis, Mycelis muralis, Paris quadrifolia, Phyteuma ovatum, Polygonatum multiflorum, Polystichum aculeatum, Prenanthes purpurea, Senecio ovatus.

On extreme ridges, secondary forests of the Ostryo–Fraxinetum can develop after clearing operations.

In places, even-aged beech forests are well cultivated. There are also many coppiced forests, in particular close to farms.

The Arunco–Fagetum is classified in the alliance Aremonio–Fagion.
