natural heritage

The present-day Vipava Valley was in the remote geological past flooded by a Tertiary Sea. On the margin of the Vipava Valley and on the Vipava Hills, surrounding the Vipava Valley, you can find tertiary sedimentary rocks, such as flysch, various sandstones and limestones. Mountain range of the Trnovo Forest and of the Gora plateau is built of mesozoik limestones and dolomites, but the Nanos plateau and the Hrušica plateau are composed of cretaceous limestones. However, the oldest rocks are found in Smrekova draga dale which date from the Late Triassic period. There are also a lot of fossils all over the valley which are evidences of evolution and life in the remote past. In the Trnovo Forest a lot of various corals were found, however, on the Nanos Plateau and the Hrušica Plateau shells were found. Nevertheless, quite a few fossils were first discovered in this area and named after the places here.

The Vipava Valley is in the southwest open towards the Mediterranean Sea and therefore influeneces of the Mediterranean climate come up and reach the Vipava Valley. Mean annual temperature in Ajdovščina is thus quite high, 12°C, monthly average minimum temperature is never below zero and vegetational period is also quite longer than in the central Slovenia. The climatic conditions enable the growth of Mediterranean vegetation, such as fig trees, kaki, laurels and others. High karst plateaus conjoin Alpine, Mediterranean and continental climates and the result of this is a diversity of flora and fauna and among them also a great deal of endemic species could be found. There is also quite a lot of wild animals too: moufflons, chamois, stags, deers, rabbits, pheasants, partridges, capercaillies, lynxes, bears and somewhere also wolves.

Although the valley has generally mild climate, it is often changed with the outbreaks of the northeastern wind bora, whichs blow down the slopes of the surrounding plateaus. Bora blows 80 km/h on average, but gusts of wind can sometimes reach speeds of up to 200 km/h. Bora ventilates the valley on one hand and on the other it influences and dictates the lifestyle and habits of the local people. Because of this wind, settlements are located in places sheltered from the wind, houses front to the south and have stones on their roofs to prevent the roof tiles from being blown off and even the trees are inclined to the south. The Bora wind also interferred in making history, as it helped the Roman army led by Theodosius I. in the Battle of the River Frigidus in 394 AD against his opponent Eugenius and his pagan army who were advancing from the west. Bora blowing from the northeast impeded pagans' battling and gained victory to Theodosius I. and his army. This battle was a decisive battle in the universal Roman Empire, as it immediately split it into the Eastern and Western part.
