Because of its special position, Velebit is influenced by a variety of climates and geographical areas, as reflected in the flora or the plant life covering the mountain. Velebit hosts plants characteristic of coastal, inland and mountain habitats. Species belonging to an area are called flora elements. Among the plants of North Velebit, boreal (northern) and arctic-alpine (northern-Alpine) flora elements are commonly found. The arrangement in which identical or closely related species grow in northern regions an on mountain tops is the result of glaciation, periods in which much of the earth was covered in ice. The plants in cold areas had then lost their living space and were forced to migrate southwards. When the ice started to melt, it become too warm for them, and only those plants growing on mountain tops, where the climate is similar to that of northern or polar regions, were able to survive. After withdrawal to the mountains, these plants became isolated, as if living on an island, surrounded by a large area of unfavourable warm habitats. In their isolation, each group of plants evolved independently from others, resulting in creation of unique species and subspecies – the endemics. Velebit is one of Croatia’s four centres of endemism.
So far over 950 species and subspecies have been recorded in the Park. Many of them are of limited, regional distribution, and some 40 are locally distributed, strict endemics. They account for 4.4 percent of North Velebit flora, which is high for European circumstances. According to the IUCN criteria – (International Union for the Conservation of Nature), 2.3 percent of species and subspecies are included in the national Red List of Threatened Plants compiled by the State Institute for Nature Protection. At European level, 5.1 percent of plant species of the Park are protected under the Bern Convention and the Habitats Directive, the two major pieces of European nature conservation legislations.

Forest Plant Communities of the Northern Velebit National Park
Much of Northern Velebit National Park (more than 80 percent of the total area) is covered in forests with easily observable altitude distribution (zoning). Biogeographically, they mostly belong to the Eurosiberian-North-American region and to a lesser extent to the Mediterranean region. Although no extensive studies of forest plant communities have yet been conducted in the Park, 14 different forest plant communities have been identified in the wider North Velebit area.
Downy Oak and oriental Hornbeam Forest (Querco-Carpinetum orientalis)
This forest community occupies large areas of the southern exposure of the Velebit mountain. Through the long centuries, even millennia, it has been intensively exploited by the local people – it was cut for timber, deforested, used for grazing cattle, etc. As a result, large areas of these plant communities today occur in form of stump forest, a forest where trees grow from the stump. They are very important for the protection of soil against erosion. In the tree layer, in addition to downy oak (Quercus pubescens) and oriental hornbeam (Carpinus orientalis) grow manna ash (Fraxinus ornus), Montpelier maple (Acer monspessulanum), Turkey oak (Quercus cerris) and true service (Sorbus domestica). The most common plant species in the shrub layer include: scorpion senna (Coronilla emerus subsp. emeroides), smoke-bush (Cotinus coggygria), Christ’s thorn (Paliurus spina-christi), bladder senna (Colutea arborescens), St Lucie cherry (Prunus mahaleb), cornelian cherry (Cornus mas) and blackthorn (Prunus spinosa). The most important ground vegetation species include: wild asparagus (Asparagus acutifolius), winter savory (Sataureja montana), spiked speedwell (Veronica spicata), red feather clover (Trifolium rubens), white dittany (Dictamnus albus) and others.
European Hop-hornbeam and Pubescent Oak Forest (Ostryo-Quercetum pubescentis)
This forest is also developed in various degraded forms of original forest. It occupies a layer above hornbeam and pubescent oak forests on the coastal slope of the Velebit mountain. It mainly occurs on calcareous soils, in the form of fragmented groves and thickets, and has great significance for the conservation of soil. In addition to European hop-hornbeam (Ostrya carpinifolia) and pubescent oak (Quercus pubescens), the most common species include: manna ash (Fraxinus ornus), Bosnian maple (Acer obtusatum), Turkey oak (Quercus cerris), Norway maple (Acer platanoides), Sessile oak (Quercus petraea) and common hornbeam (Carpinus betulus).
Beech Forest with Autumn Moor Grass (Seslerio autumnalis-Fagetum)
This forest covers the lower stratum of beech forests which grow on the coastal slopes of the Velebit mountain. It occurs at altitudes between 700 and 1300 meters and is characterized by the presence of thermophilic species of autumn moor grass (Sesleria autumnalis) which covers the whole ground like a carpet in autumn. The tree layer is dominated by common beech (Fagus sylvatica), with some patches of Bosnian maple (Acer obtusatum), European hop-hornbeam (Ostrya carpinifolia), sycamore (Acer pseudoplatanus), common whitebeam (Sorbus aria) and manna ash (Fraxinus ornus). The shrub layer is mainly composed of wayfaring tree (Viburnum lantana), cornelian cherry (Cornus mas), warted spindle (Euonymus verrucosus) and purging buckthorn (Rhamnus cathartica). Most important species in the ground vegetation layer include: autumn moor grass (Sesleria autumnalis), bastard balm (Melittis melissophyllum), fingered sedge (Carex digitata), corymbflower tansy (Tanacetum corymbosum), bastard agrimony (Aremonia agrymonoides), nettle-leaved bellflower (Campanula trachelium) and others.

This is a very interesting forest community containing a number of Mediterranean species, such as prickly juniper (Juniperus oxycedrus), Montpellier maple (Acer monspessulanum), terebinth (Pistacia terebinthus), scorpion senna (Coronilla emerus subsp. emeroides) and others. Next to them also grow typical „pinewood“ species such as: spring heath (Erica herbacea), hairy cotoneaster (Cotoneaster nebrodensis), june-berry (Amelanchier ovalis) and others. In North Velebit indigenous black pine forests are a relict - remains of what were once much wider spread forests.
Mountain Beech forest (Lamio orvalae–Fagetum)
This community occupies a very narrow belt on the inland-facing side of the Velebit mountain at heights between 600 and 900 meters above sea level. In addition to beech, sycamore (Acer pseudoplatanus), wych elm (Ulmus glabra) and other species are found, too.
Dinaric Beech and Fir Forest (Omphalodo vernae-Fagetum)

It occupies the highest regions of the Park where it grows at altitudes between 1200 to mostly 1500 meters in conditions characterized by large amounts of snow, low temperatures, short growing season and strong winds. The trees in this forest are typically curved in the lower part of the trunk due to the pressure of prolonged snow cover and wind. The tree layer is dominated by common beech (Fagus sylvatica), but sycamore (Acer pseudoplatanus) is also very common. The shrub layer is less developed and is composed of February daphne (Daphne mezereum), alpine honeysuckle (Lonicera alpigena), with bigleaf willow (Salix appendiculata), stone bramble (Rubus saxatilis), alpine rose (Rosa pendulina) and alpine currant (Ribes alpinum) growing at higher elevations. The most significant species in the ground vegetation layer include: holly fern (Polystichum lonchitis), round-leaved saxifrage (Saxifraga rotundifolia), alpine adenostyles (Adenostyles alpina), wood colt’s foot (Homogyne sylvestris), nettle-leaved speedwell (Veronica urticifolia), large white buttercup (Ranunculus platanifolius), yellow thistle (Cirsium erisithales), three-leaved valerian (Valeriana tripteris), broad-leaved garlic (Allium ursinum) and others.

In north Velebit this community grows around the village of Krasno.
Spruce Forest with Bastard Agrimony (Aremonio-Piceetum abietis)
Especially developed in Štirovača and on the fringes of numerous mountain meadows, it's a plant community of so-called frost pockets, wide valleys where the concentration of cold air is higher. The tree stratum is dominated by norway spruce (Picea abies) with some european silver fir (Abies alba) and common beech trees (Fagus sylvatica) of lesser vitality. The shrub layer is less well developed and comprises species such as common rowan (Sorbus aucuparia) and black-berried honeysuckle (Lonicera nigra). The ground vegetation layer is very lush and abounds in acidophilic species (those that thrive in acid soil), such as blue whortleberry (Vaccinium myrtillus), stiff clubmoss (Lycopodium annotinum), hairy woodrush (Luzula pilosa), with other important species comprising common wood sorrel (Oxalis acetosella), raspberry (Rubus idaeus), willow gentian (Gentiana asclepiadea), trifoliate bittercress (Cardamine trifolia) and many others. Bastard agrimony (Aremonia agrimonoides) is commonly found within the community, but not in great abundance.
Sub-alpine Spruce Forest with Listera (Laserpitio krapfii–Piceetum abietis)
The largest complexes of this forest are found in Smrčeve doline and Lubenovac. It develops in the cold, steep, enclosed northern sinkholes and valleys, with a high and long lasting snow cover. The tree layer is almost exclusively composed of norway spruce (Picea abies), and the shrub layer consists of black-berried honeysuckle (Lonicera nigra) and bigleaf willow (Salix appendiculata), with blue-berried honeysuckle (Lonicera borbasiana) found more rarely. The common plants in the ground vegetation layer are those belonging to coniferous forest acidophilic species: blue whortleberry (Vaccinium myrtillus), cowberry (Vaccinium vitis-idaea), stif clubmoss (Lycopodium annotinum), fir clubmoss (Huperzia selago), heart-leaved twayblade (Listera cordata) and species growing in pre-alpine beech forests: yellow thistle (Cirsium erisithales), three-leaved valerian (Valeriana tripteris), alpine clematis (Clematis alpina) and others. Commonly found are also different species of moss from the genera Plagiothecium, feather moss (Hylocomium sp.), peat moss (Sphagnum sp.), and haircap mos (Polytrichum sp.).
Spruce Forest with Small Reed (Hyperico griesebachii–Piceetum abietis)
It grows around Zavižan, on Hajdučki kukovi and Rožanski kukovi on steep calcareous blocks 1400 meters above sea level. The tree layer is dominated by norway spruce (Picea abies). Other species to be found include common rowan (Sorbus aucuparia), with occasional stunted – krummholz common beech trees (Fagus sylvatica). In the shrub and ground vegetation layers, pre-alpine species dominate such as: alpine rose (Rosa pendulina), reedgrass (Calamagrostis varia), alpine juniper (Juniperus communis subsp. nana), blue-berried honeysuckle (Lonicera borbasiana), european mountain pine (Pinus mugo), alpine currant (Ribes alpinum), large-leaved willow (Salix appendiculata), silvery yarrow (Achillea clavenae) and others.
Spruce Forest with Adenosytles (Adenostylo alliariae-Piceetum abietis)
It grows in wider bottoms of shallow sinkholes which are wetter, colder and richer in fertile soil – humus – than the surrounding habitats. In such forest habitats the snow cover lasts long and the ground is very wet. The dominant type of vegetation are tall herbs: Adenostyles (Adenostyles alliariae), alpine blue-sow-thistle (Cicerbita alpina), Austrian leopard's bane (Doronicum austriacum), lady fern (Athyrium filix-femina), white butterbur (Petasites albus), meadow grass (Poa hybrida), pond water crowfoot (Ranunculus platanifolius), whorled Solomon's seal (Polygonatum verticillatum), wood chickweed (Stellaria nemorum) and two-flower violet (Viola biflora). Unlike other spruce communities, this community is characterized by the absence of large moss complexes with blue whortleberry (Vaccinium myrtillus) and norway spruce (Picea abies) shrubs growing on trunks and fallen trees. In North Velebit, this community grows in a mosaic pattern with nicest stands to be found in the Lom area.
Mountain Pine Krummholz and Blue-berried Honeysuckle Forest (Lonicero borbasianae-Pinetum mugi)
This forest inhabits the uppermost peaks of North Velebit and forms the upper boundary of forest vegetation in the Dinaric mountains 1350 meters above sea level. It covers many rocky peaks, ridges and slopes. The dominating species is european mountian pine (Pinus mugo) which develops very long and low-lying branches under the influence of long-lasting snow cover and strong air currents and covers vast, impassable regions. In addition to mugo pine and a few scrubby norway spruce trees (Picea abies), and krumholz – stunted, shrubby common beech (Fagus sylvatica) other species to be found here include: large-leaved willow (Salix appendiculata), common rowan (Sorbus aucuparia), blue-berried honeysuckle (Lonicera borbasiana), alpine rose (Rosa pendulina), false medlar (Sorbus chamaemespilus), alpine currant (Ribes alpinum), alpine juniper (Juniperus communis subsp. nana), European cotoneaster (Cotoneaster intergerrimus), stone bramble (Rubus saxatilis), blue whortleberry (Vaccinium myrtillus), cowberry (Vaccinium vitis-idaea) and other species. Pine scrub has an immense protective function as it overgrows many steep and craggy areas containing countless Croatian endemics and rare plant species.
