THE European bison, which used to roam across Europe until it was hunted to extinction in the wild in 1927, is now beginning to make a comeback thanks to an initiative taking place in Romania.

A small herd, 17 in total, of the continent's largest wild land mammal were recently brought into the Tarcu Mountain Reserve in Romania's Southern Carpathians, with a further 10 more due later this summer, as part of a complex rewilding operation.

Wildlife Worldwide has been invited by Rewilding Europe, and its partner WWF Romania, to be the only UK tour operator to offer trips to witness the further reintroduction of bison between the middle of next month and the end of August.

Wildlife Worldwide's brand new tailor-made five-day adventure will involve learning about the bison and their rewilding from the people who spearheaded the operation and will feature other fascinating wildlife in the remote TarcuMountains. The initiative is particularly exciting for the local community with bison more rare in the wild than the black rhino in Africa, as well as being an important part of Romania's natural heritage, through legends, myths and place names.

Extinct from the area for over 250 years, this new bison population has been brought in from several corners of Europe so that within 10 years there will be some 500 European bison living in total freedom in an area spanning 59,000 hectares of remote mountains, meadows and valleys.

Once released into the wild, the bison will not be fed or handled, so that they will become a full part of their natural ecosystem. Natural grazing by large herbivores is one of the key ecological factors in the landscapes upon which a large part of Europe's biodiversity is dependent. It’s anticipated that it will also stimulate a comeback of other wildlife species such as red deer, roe deer, chamois and the carnivores connected to them.

Having first been released into an acclimatisation zone, the bison will then progress to a larger zone to rewild; in other words learn the skills necessary for their survival and form a social herd structure. In early September 2014 the first bison will finally be released into the wild and become the first to roam the Tarcu Mountains since the 18th century.

By becoming a tourism attraction, the bison's introduction will help create business opportunities and employment for the local community. Indeed, some locals have already been trained as rangers and bison guides. Earlier this month, to welcome the project, the village priest blessed the animals and two local children opened the door of the truck used to transport them, while later the entire village celebrated their arrival at a massive evening 'Bison party'.

While the focus on the trip to the Tarcu Mountains Reserve will be the bison, there are other elements to this fascinating five-day trip when visitors will stay in a simple, clean guest house in Rusca village within walking distance of the bison. In the evenings there are talks on topics including bears (Romania has more brown bears than British Columbia), the bison reintroduction project and the region's biodiversity.

Accompanied by an expert, guests will be able to take a leisurely three-hour walk to see the bison at La Magura near the hamlet of Plopu and, after lunch, drive half-an-hour to the newly built Bison Centre to learn more about these mammals.

The following day the small group drives and walks to a hide, deep in the mountains, to try to find brown bears and learn about the other inhabitants of the forest. Due to the history of hunting in the region, the bear population is still shy, so there are no guaranteed sightings.

Other highlights of the trip include:-

• in the company of a guide and local forester, explore on foot a nearby area of virgin forest in the Hideg Valley which is highly populated with woodpeckers (nearly all European species), other rare birds and endemic plants;

• discovering the Domogled-Valea Cernei National Park one hour's drive away, a mountainous area famous for its great biodiversity and its beautiful peaks, cirques, valleys, waterfalls, sinkholes, limestone pavements and caves which shelter an extremely rich variety of flora and fauna including 1,500 species of butterfly;

• experiencing the fascinating local culture and traditions of the region, unchanged for hundreds of years and still relatively untouched.
