- Bear conservation
Bear conservation refers to the management of
bearsand their habitatwith a view to preventing their extinction.
Bears face serious threats on many fronts, most of which are due to human activity. Whether indirect, as in human encroachment on their natural habitats due to crop cultivation,
deforestationor timber harvest, or directly from their killing for protection of property or for unregulated or sport hunting, or for their use in primitive medicines and aphrodisiacs.
In a paper presented at the
International Bear Association’s Eighth International Conference on Bear Research and Management, Victoria, British Columbia, Canada, in 1989, Christopher Servheen, of the U.S. Fish and Wildlife Service, stated that
Conservation efforts on bears must be based on accurate biological information and knowledge of the habitat requirements of the species. Even when required biological data are available, implementation of conservation efforts requires an effective governmental commitment and incorporation of the needs of the local people into bear conservation. Management implementation and public education remain the greatest challenges in bear conservation.

According to Servheen, bear conservation efforts vary from the intensive and highly organized management of the grizzly bear in the United States to little or no management of most Asian species.
Likewise, successful international co-operation in conservation and management is exemplified by the work done on the polar bear in the Arctic. Several other species also need international cooperation to if they are to survive.
IUCN Red List
Of the world’s eight existing bear species, except for the
Polar bear(Ursus maritimus) and the American black bear(U. americanus), the other six, that is,
Giant panda(Ailuropoda melanoleuca)
Brown bear(U. arctos)
Spectacled bear(Tremarctos ornatus)
Asiatic black bear(U. thibetanus)
Sloth bear(Melursus ursinus)
Sun bear(Helarctos malayanus)
face varying degrees of vulnerability. The 2007
IUCN Red List, published on 12 September 2007, [ [http://www.iucn.org/en/news/archive/2007/09/12_pr_redlist.htm Extinction crisis escalates: Red List shows apes, corals, vultures, dolphins all in danger - IUCN News ] ] includes two species, the Giant panda and the Sun bear as threatened with extinction, and even "least concern" species such as the brown bear, although not considered to be at risk in North America and parts of Europe and the Soviet Union, are at risk of extirpationin certain countries or regions.
The process of decline and/or extinction of the brown bear in Europe is well-documented. Starting with their extinction in Denmark around 3000 B.C., in Great Britain during the 10th century, in eastern Germany in 1770, in Bavaria in 1836, in Switzerland in 1904, and in the French Alps in 1937.
Although the inclusion of the brown bear as of
Least Concernon the 2006 IUCN Red List of Threatened Species refers to their global population, the fact is that local populations are increasingly becoming scarcer. And as the IUCN itself adds
Least Concern does not always mean that species are not at risk. There are declining species that are evaluated as Least Concern.
Such regional variations are most obvious in Spain where the only remaining bear, the
Cantabrian brown bearis under threat.
Spain’s ministry of the environment, in its "Catálogo Nacional de Especies Amenezadas" [ [http://www.mma.es/portal/secciones/biodiversidad/especies_amenazadas/catalogo_especies/ Ministerio de Medio Ambiente:Biodiversity:Conservation of Endangered Species :National Catalogue of Endangered Species ] ] lists the brown bear as in danger of extinction in Spain.
According to an article published December 2007 in the Spanish national daily
El País, [ [http://www.elpais.com/articulo/sociedad/Denuncian/muerte/segundo/oso/Palencia/meses/elpepusoc/20071202elpepisoc_2/Tes Denuncian la muerte de un segundo oso en Palencia en cuatro meses · ELPAÍS.com ] ] 8 brown bears have been killed, either by poisoned bait or illegal hunting, in the Cantabrian Mountainssince the year 2000. The Cantabrian Brown Bear population is currently (2007) estimated at around 170, divided between the 140 in the Western section and 25-30 in the Eastern. Leading Spanish experts have warned that the bear population will not be viable until there are "several hundred". Their viability is further compromised by the regional authorities' keenness to allow construction of a ski resort at San Glorio, a project which has met strong opposition from many sectors, as well as that of the central government.
