Otter

Otter

The Otter (Lutra lutra Linnaeus, 1758) is one of the most common mammals in the Old World. In the second half of 20th century there was a decrease of the range and visible decline in the numbers of this species, especially in North Africa, Western and Central Europe. The main reasons were water pollution, habitat loss, and poaching.
This is a species of high conservation status, being a current object of study. The species is listed in Appendix II to the Bern Convention, Appendix I on the Convention on Illegal Trade in Endangered Species, and Annexes 2 and 4 to the Council Directive on the conservation of natural habitats and of wild fauna and flora. The Otter is one of the priority species in the establishment of NATURA 2000 European Ecological Network; it is included in the IUCN Red List of Threatened Species under the “near threatened” category. Often, the species given as an indicator of the state of entire catchment areas, as it is reflected on the Otter population.



We contribute to the conservation and studying of this species by participating in the following projects:

Gathering and analyzing available data on the habitats of otter (Lutra Lutra) in Bulgaria and participating in the development of a concept for the conservation of this species in Bulgaria within NATURA 2000. Dilyan Georgiev (Green Balkans) and Yordan Koshev (Balkani), 2006: (Report on NATURA 2000, submitted to the Ministry of Environment and Waters).

Studying the Otter (Lutra Lutra L.) in parts of the rivers valleys of Yantra, Russenski Lom, Beli Lom, Cherni Lom and  "Mechka" fish-breeding ponds, in order  to expand the park territory and  designate new protected areas. Yordan Koshev (Balkani) and Dilyan Georgiev (Green Balkans) 2006: (under a project run by “Russensky Lom” Nature Park).
