Abstract: One of the species that offer a unique feature to the Geopark Mehedinti Plateau is Testudo hermanni boettgeri (land turtle or Hermann’s turtle), a communitarian interest species, strictly protected, included in the Red Book of the Vertebrates in Romania.
Being a middle-sided vertebrate, it is about 4 cm long when it is born and about 15-30 cm long as an adult. It prefers the open spaces and it can be met at altitudes higher than 600-700 m. It is very sensitive regarding the temperature variations. It is mainly a vegetarian and it eats leaves, berries, vegetables and extremely seldom little invertebrates. Hermann’ turtle is a lonely species that hibernates from October to the end of April, buried in sandy soil under stones, at about 15 cm below. Usually it reproduces at the end of spring, but unfortunately its survival rate is very little, part of the eggs don’t lay and the young turtles have to face numerous predators (boars, foxes, raping birds etc.).
Key words: Testudo hermanni boettgeri, protected species, conservation, Geopark Mehedinti Plateau

Abstract: Biofuel can be defined as solid, liquid, or gas fuel created by biological material, most commonly plants. This distinguishes it from fossil fuel, which is derived from long dead biological material. Biofuel can be theoretically produced from any (biological) carbon source. Biofuels are also thought to be a big factor in the alarming rise in food prices, which is hitting poorer countries hard. Without doubt, more biofuels means higher food prices and more people on the brink of starvation.
Key words: biofuels, fossil fuels, food prices

Abstract: Geologic features play a key role in the establishment of a vegetation cover. The most obvious aspect about the relationship between geology and vegetation can be understood if we look at the way in which the geology influences the land forms and by this influences the microclimate and plant species.

Abstract: Soil is defined as the top layer of the earth’s crust. It is formed by mineral particles, organic matter, water, air and living organisms. It is in fact an extremely complex, variable and living medium. The interface between the earth, the air and the water, soil is a non-renewable resource which performs many vital functions: food and other biomass production, storage, filtration and transformation of many substances including water, carbon, nitrogen. Soil has a role as a habitat and gene pool, serves as a platform for human activities, landscape and heritage and acts as a provider of raw materials. These functions are worthy of protection because of their socio-economic as well as environmental importance.
Key words: soil layer, interface, vital functions, protection

Abstract: In the Târnava hydrographical basin it was differentiate five categories of water uses: water for population, industry, irrigation, zoo technology, pisciculture. The main uses in basin have the following percentages: 63,4 % of the total captivated volume is used for industry, 34 % of the total volume represents drinking water, 2 % for irrigation systems and other agricultural needs. Water alimentations are achieved by water captivation with the help of 28 surface water intake or 4 underground drilling. One type of special use constitutes the anthropic lakes. Important are the 6 accumulation lakes, the pools and ponds are much smaller and have agricultural-piscicle destinations.
Key words: Târnava hydrographical basin, water uses, anthropic lake

Abstract: The flash-floods were seldom signalled in the mountain basin of the Arieş river, becoming more frequent starting with the year 2002, especially on the streams in the middle basin of the Arieş River. Similar events were observed by the inhabitants in the past; to mention the flash-flood produced on the Valea Morii stream (Vidra commune) on June 19th, 1975, when seven people died. The flash-floods during June 18th, 2006 also had significant effects particularly at geomorphic level and were chosen for a detailed study.

Abstract: The Deva–Simeria–Hunedoara conurbation represents one of the most ambitiose urban planning project in recent years in Romania, bringing together ovrer 150.000 people from 3 towns and 12 vilages. This project is so important because its goal is to resolve most of the area’s environmental problems by better planing the use of the land and changing the use of the old and abondoned industrial space. The planning of this conurbation started in the summer of 2005 and now after almost three years of hard work we can say that the Deva–Simeria–Hunedoara conurbation is about to become reality and also it will be a source of inspiration for other planning projects in Romania.
Key words: conurbation, land, environment, industrial space

Abstract: The waters of the Danube, which flow into the Black Sea, form the largest and best preserved of Europe's deltas. Danube Delta is the youngest and least stabile territory of Europe, with three branches, the home of a lot of  species of birds, fish and plants. Behind of what it looks, Danube Delta has a long history of changings, most of them giving to those lands new forms, making it one from the most interesting place from Europe. In 1998, under UNESCO Programme on Man and the Biosphere, the 6264,03 Km2 of Danube Delta were established as Biosphere Reserve shared by Romania and Ukraine. This delta is a Paradise known all over the world.
Key words: Danube Delta, biodiversity, protection, Biosphere Reserve

Abstract: Ecology is an important issue in development of protected areas. Through education, mentalities, changing as well as self perfection human being will be able really reach an ecological behaviour. All the developed countries struggle against environment depreciation and for the protection going disappearance flora and fauna. In Romania have been created natural parks and reservation where many species of plants and animals are render protection. As for Olanesti river area there are four such reservations as well as the National Park Buila-Vanturarita. In order to keep safely Olanesti River area flora and fauna as well as the mostly attractive landscape it is compulsory to insert it among Romania’s natural reservation.

Abstract: The spruce is, without doubt, the most important coniferous tree from our parts and numerous other European countries. In our forests, the spruce is only second to beech trees in overall importance. It is remarkable that in the Romanian Carpathians, the spruce in not unitary by any means. For example, the spruce from the Oriental Carpathians presents production potential, possibility of regeneration and a superior vitality when compared with the spruce from the Meridional Carpathians, thought of by the famous forester Iuliu Moldovan as "a tired form". However, this should not be assimilated with the biological depression which is far from manifesting. The geographical landscape of the region to be studied is mountainous and is situated in the north-western part of the Oriental Carpathians, the north-western extremity of the Calimani Mountains this being one of the best landscapes for spruce development because both climatic and edaphic factors are at the optimum of the ecologic spectrum required by this species. Variability is a characteristic of the living world which represents the totality of phenotypical traits of an individual so that no two individuals are identical.
Key words: spruce, phenotypical varability, Calimani Mountains, environmental factors
