Pteridophyta and Spermatophyta are the main representatives of flora of Aenos National Park estimated to be 400 species. For other important big families, like Fungi, Lichens and Bryophytes on mount Aenos, a few informationis known.
3 out of the 8 known endemic Cephalonian species and subspecies are exclusively endemic to Aenos National Park:
–Viola cephalonica Bornm.: it thrives at 1.500-1.600 m of altitude and grows in the cracks of limestone rocks, as well as in rocky positions. It’s spread in the area of Chionistra, around the antennas (Figure 1).
–Scutellaria rupestris Boiss. & Heldr. subsp. cephalonica (Bornm.) Greuter & Burdet: it thrives at 1.500-1.600 m in rocky and limestone substrate.
–Ajuga orientalis subsp. aenesia (Heldr.) Phitos & Damboldt: it thrives at 400-1.600 m in limestone substrate.
Except previously mentioned Aenos endemic species, there are also other endemic species of the Hellenic area. Some of these species were discovered and first described in Kefalonia, so that in their official scientific name it was comprised the name of the island. In particular, these species were first recorded in mount Aenos, and comprise Erysimum cephalonicum Polatschek, Astragalus sempervivens subsp. cephalonicus (C.Presl) Ascherson & Graebner, Campanula garganica subsp. cephallenica (Feer) Hayek, Poa cephalonica H. Scholz, ecc. Later on, the aforementioned species were also recorded in other Greek areas.Abies cephalonica Loudon makes part of this category, and will be further described on mount Aenos vegetation (Figure 2).

Viola odorata L. (Οικογ. Violaceae): Aenos, March
The Vegetation of Mt. Aenos National Park
The dominant type of Aenos National Park vegetation is the forest of kefalonian fir (Figure 4). Abies cephalonica confers considerable multiple values to Kefalonia where it was first described and got its name from. It is related to the history of the island and the scientific research because of the importance of Abies cephalonica forests thriving in an isolated small area. Because of its geographic isolation, Abies cephalonica has ensured its pure perpetuation in the “locus classicus”. Apart from Kefalonia, this species thrives to Peloponnese, Central Greece, Euboea, Thessaly and Epirus.
In Aenos National Park, Abies cephalonica grows in the northwest edges of mount Roudi, at 550 m of altitude, within the upper limit of macchie vegetation and reaches 1.600 m of altitude, near Aenos peak called Megas Soros. It’s outspread, in Roudi and Aenos main body, inconstant, but intermittent in the form of smaller or bigger clusters which are equally dense. The nudity of Aenos steep southwest slopes is impressive, and it is due to forest destruction from logging, overgrazing, fires and soil composition and inclination. In our days, apart from Abies cephalonica, no other forest species is observed in the National Park. In the saddle between Roudi and Aenos trees Quercus pubescens Willd grow individually or in clusters, descending to the east till 500 meters of altitude and below the road that starts from Saint Eleftherios direction Tsakarisianos, where population structure is still very dense. There is no doubt that in the past, the area was covered by an extended forest ofthe deciduous species Quercus pubescens.
Consistent shrubby vegetation thrivesfrom the municipal road linking Sami to Argostoli, in the north slopes of mount Roudi, spreading up to almost 750 m of altitude, forming the characteristic ecosystem of macquis vegetation (Figure 5). It consists of evergreen hard leaved shrubby or semi-arboreal species like: Pistacia lentiscus, Quercus coccifera, Quercus ilex, Phillyrea latifolia, Arbutus unedo, Arbutus adrachne, and a hybrid form of A. unedo and adrachne. From 700 m of altitude, this impenetrable vegetation gets gradually replaced first by the fir forest and then by small bushes of Quercus coccifera in the higher altitudes, where fir clusters are sparse or totally absent.
The project entitled: "PANAS - The monumental forests of the Ionian Sea as hotspots of biodiversity and high biopharmaceutical value of macrofruits: mapping, inventory, assessment, networking, conservation and sustainable use" has been included in the O.P.. Ionian Islands, 2014-2020 (Priority Axis 2 - "Environmental Protection and Sustainable Development") and is co-financed by 80% from the European Regional Development Fund and 20% from National Resources.
