Introductory notes:

Tectonic setting of BulgariaThe Alpine Orogen of Southeast Europe splits in two on the Balkans. The Northern Branch consists of the Carpathian and the Balkanide Fold-thrust Belts. The Southern Branch consists of the Dinarides-Albanides- Hellenides Belt. Bulgaria belongs to the Northern Branch of the orogen.

Geology of Bulgaria Although small (110 000 km2) Bulgaria encloses the remains of various Phanerozoic and older rock complexes and terraines . The Paleozoic terraines are mainly of Peri-Gondwana origin and were docked to Europe, before the latest Carboniferous. They were heavily reworked in Alpine time. The Mesozoic evolution is marked by the opening and closing of several marginal Peri- Thetys basins.

Geomorphology and neotectonic features

Miocene - Quaternary and active structures are extensively developed throughout Bulgaria. Undergoing active extension is forming a system of horsts and grabens, similar to well- known extensional systems, like the Western United States.

Much of the present-day morphology is the immediate result of neotectonic events. In many places the topography is the direct result of expression of very young and active extensional structures

Protected geosites in Bulgaria

The richness of different various rocks, rock sequences, structural events and intensive present-day relief building has led to the occurrence of different in type geosites of both special scientific and aesthetic interests. They are split all over the country

Nature and Geoconservation in Bulgaria – a historical review

The idea for conservation of particular natural sites in Bulgaria dates from the beginning of last century. In 1927 the Society of the Bulgarian Foresters urged systematic activities. An Union of Native Nature Protection was created.

The first steps of the Union of Native Nature Protection were difficult by the lack of a special nature protection law. However, the first tworeserves were declared in 1933 with a special order of the Ministry of the Agriculture and State Estates.

In 1936 by governmental decree was proclaimed the first Bulgarian National Park, which is one of the first on the Balkans.

In 1933 a special complement dedicated to the protected territories as well as to the protection of some biota was included to the Law for the Forests.

Legal protection

First official legislation exists since 1937. Only 50 natural sites were protected then. Since, only the state has been entitled to do so.

In 1960 the so-called Decree on Natural Protection was passed and the number became already 200. In 1967, the New Nature Protection Law was approved and about 1500 natural sites were protected. In 1994 a National Service for Nature Protection with the Ministry of the Environment and the Waters, established as a state body responsible for the conservation of both the biological variety and the abiotic nature of Bulgaria.

Presently the number of the protected sites is over 1200. With the exception of some beautiful natural landscapes and rock formations, and few SSSI which are be regarded as elements of the geologicalheritage, the majority of the protected sites are above all biological sites.

Present-day legislation; List of protected geosites

• In 1998

a new legislation related only to the preserved territories was adopted. According to it the preserved territories

were divided into 6

categories: Reserves, National parks, Natural beauty spots, Supported reserves, Natural parks, and, Preserved sites. Four categories are of significance for the geosites. However, the geosites have little place in the text of the law. Nothing is mentioned about geoparks.

• The first list of geological heritage

in Bulgaria was published in 1964 and 55 geological sites

were included in it. Ten years later, in 1974, they

became 224

and now

stands at over 360.

List of the protected geosites

• Caves 107• water- falls73• ground “pyramids” 6• rock “pyramides” 44• upright rocks 4• rock “mushrooms” 4• karst valleys and canyons 12• rock bridges 18

• single rocks of specific feature 65

• lakes, marshes and limans 20• dunes 17• fossil site 12• karst springs 9• upright rock columns 4• other (moraines, palaeo -

volcanoes; mineral occurrences, etc.) 3

The different groups of geosites are quite irregularly represented. With few exceptions, these are mainly sites with geomorphological features. Only 5% are geosites of Special Scientific Importance

1998 –

UNESCO Geopark Program

During the ProGEO annual meeting the concept of UNESCO GEOPARK Program was firstly advertised and the idea for the creation of geoparks was adopted by the Bulgarian geologists. Potential geoparks are under active consideration, based mainly on the national Framework list.

The UNESCO Geopark Concept:

• A UNESCO Geoparks is a territory with well-defined limits and comprises a number of geological heritage sites of special scientific importance, rarity or beauty

• It may not be solely of geological significance but also of archaeological, ecological, historical or cultural value

• The sites are linked to one another in a formally managed park-type situation

• The Geopark is run by designated authority which adopts its own territorial policy for sustainable regional socio-economic development

European and Global Network of Geoparks

As a result of further development already 37 Geoparks in several European countries are created and united into the so-called European Network of Geoparks. This very impressive Geopark concept found further development and the Global Network of Geoparks was launched in 2004th.

? Unfortunately, up to date no European geoparks have been created in Bulgaria. However, potential geoparks are under active consideration.

Research projects in Bulgaria as a base for geopark creation

During 2001-2003 was accomplished the project “Register and Cadastre of the Bulgarian geological phenomena”. More than 200 geological sites have been described in details and registered in a data base form, using a unified registration form for evaluation.

A first project on geconservation “The Geological Heritage of Bulgaria: sites of Special Scientific Interest (SSI)”, was accomplished during 1996-2000

Unfortunately all projects aiming the creation of a European Geopark were not supported by the state institutions

In 2005 was published a framework list of the Bulgarian geosites

All these project as well as numerous publication provide a significant scientific base for the creation of geoparks.

After 2002 a project with the financial support of PHARE created some geotrails in a spectacular carstic area, declaring it as the first Bulgarian geopark. However, this territory has neither administrative, neither legal bases and is difficult to be considered as a geopark.

The general overview of all discussed areas is completed by the required numerous historical, archeological, cultural

and biological sites.

The Madara Horseman –

a UNESCO Monument

Some of the Bulgarian geosites represent a combination of sites of geological and biological interest (like some lakes on the Black Sea cost, National Parks Rila and Pirin,etc.), however they are under protection mainly for their significance for the biodiversity.

Multi valuable protected natural site

National Park Pirin a UNESCO site

Some other sites having mainly historical value are include in the UNESCO World Heritage List, but they have also a value as geological

sites in a broad sense.

Ivanovo rock churches –

a UNESCO World monument

Varna NecropolisThe oldest gold artifacts of the world – 5000 B.C.A discovery on the black Sea coast –is it related to the flooding of the Black Sea?

Final Notes:

Bulgaria has a divers and rich geological heritage.

Unfortunately, its geopark potential is still unexploited.

The creation of national geoparks is considered as a very important goal and several prospective areas are regarded as potential geoparks

The creation of geoparks will not only enlarge the opportunities for tourism in new areas as well as in such with already established touristic interest, but will also contribute to the sustainable development, thus meeting the requirements for a UNESCO GEOPARK.

Thank you for your attention!
