Protecting Mediterranean Monk Seals

Two Mediterranean Monk Seals

This sight is becoming more frequent again: monk seal with offspring

Monk seals are among the most mysterious mammals in Europe. Little is known about the way of life of this species. The seals, which once had a population covering the whole Mediterranean region and neighbouring seas, are now greatly endangered. Until a few years ago, it was considered one of the rarest marine mammals. Thanks in part to the conservation efforts of EuroNatur, populations have recovered in recent years.

Many Dangers

Habitat destruction, pollution of sea waters and overfishing are challenging the survival of the monk seal. Undisturbed sandy beaches and rocky coastal cliffs and grottos have become rare in their entire area of distribution. Scuba divers, tourists and fishermen are increasingly invading the remotest spots. This means that not only are the valuable quiet places for the seals to rest under threat but the very rearing of their young.

Our efforts show success

The largest colony of Mediterranean monk seals is not in fact in the Mediterranean but at Cap Blanc, a peninsula on the Atlantic coast of Mauritania. It is estimated that 40% of the total population lives in the colony. This is one of the focal points of EuroNatur's work for the protection of these seals. Alongside this are there is also a further central area of distribution and that is in Greece. Since the beginning of the 1990s EuroNatur has been working on the Greek island of Alonnisos for the protection of the monk seal colony living off the coast there.

These measures are proving successful, which results in a growing seal population and an increase of their geographic range. In order to continue to enable this favourable development, EuroNatur and their partner organisations in South East Europe have joined forces in 2017 to campaign for the protection and exploration of the Mediterranean monk seals in Greece, as well as their dispersal into the northeastern waters of the Adriatic.

Protecting Bats

EuroNatur also works to protect bats in the German-Polish border area. January 2018 saw the launch of the Project Natura Viadrina+ which is being carried out within the framework of the cooperation programme INTERREG VA BB-PL 2014–2020. The project is being promoted jointly by the Landscape Conservation Association of the Middle Oder River (Landschaftspflegeverband Mittlere Oder e.V.), the Polish conservation organisation Liga Ochrony Przyrody, EuroNatur and the Association of the Landscape Parks of the Lubuskie Province in Poland (Vereinigung der Landschaftsparks der Provinz Lubuskie).

Saving bat roost buildings from deterioration

The project area has two important winter bat roosts. One of these is the Nietoperek reserve, the most important northern European winter roost with over 35 000 individuals (including c.29 000 greater mouse-eared) which is located in a 36 km long bunker complex at Pniewo (7200 ha). The other is to be found in the Old Brewery (0.25 ha) in Frankfurt (Oder). The building, which is part of the former Ostquell Brewery and owned by EuroNatur, is of national importance for its c.700 hibernating greater mouse-eared bats.

As endangered species, all bats are protected across Europe. The safeguarding and maintenance of their winter roost is therefore of great importance. The building structures of both these roosts are under severe threat from vandalism or decay, and represent a risk for the bat conservationists who enter the buildings once a year to carry out a population count of these nocturnal mammals. The poor structural state of both winter roosts also means that they cannot be used in publicity work. It is therefore vital in the long term that one of the main components in the renovation project is the structural repair of the two winter bat roosts.

Nature conservation on your doorstep - EuroNatur projects in Germany


With its soft rolling hills, luxuriant beech and hornbeam woods, varied waters valleys, wet meadows, sand and heathland Brandenburg captivates the visitor with the sheer variety of its precious natural landscapes. The many different forms of habitats offering a home to numerous endangered species such as the European Otter, White-tailed Eagle, Osprey, Kingfisher and Black stork.

At the end of the 1990s these natural paradises were in serious danger. The Federal Government had planned the privatisation of large, ecologically valuable conservation areas which had remained state property in GDR times. Reacting to the numerous protests of nature conservation associations, in 2000 the Federal Government created the legal basis for these areas to become the property of the Länder and Nature Conservation Trusts.

EuroNatur declared its willingness to take over a total area of around 1000 hectares and in this way prevent the fragmentation and destruction of nature reserves so rich in species. In these areas, among other things, we are working on the gradual conversion of pure pine stands into species-rich and site-appropriate mixed deciduous forests or on the renaturation of peatlands - an important contribution to climate protection.

A place to breathe: the vast heath landscape of the Senne

A decommissioned tank: military training areas have developed into refuges of biodiversity, not only in the Senne.

At the foot of the Teutoburg Forest there is the sandy heath country of the Senne. The ancient cultured landscape developed largely as a result of grazing methods which began as early as the Neolithic period (around 3 500 B.C.) and which changed the country dramatically: where previously extensive forests had been the dominant feature, with the advent of heathland sheep farming, now largely lost, extensive areas of heathland soon prevailed.

From the middle of the 19th century bit by bit the areas were reforested and open heathland was gradually transformed back into a woodland landscape. With the retreat of the heath its characteristic animals and plants grew rarer. Today for instance Maiden Pink, Hairy Greenweed, the Sand Lizard and many insect species, such as the Small Emperor Moth, are on the Red List.

The original heathland only remains on a few sites. In the Senne the establishment of a military training area 100 years ago was of benefit for the retention of heathland. Military use ensured that the area remained open land. Outside the training area there are comparatively few areas of heathland left. EuroNatur has been supporting the Paderborn-Senne Biological Station for many years now in the care and preservation of this valuable heritage with its wealth of species.
