Number of species in IUCN Red List categories from Mediterranean countries
Mediterranean species and habitats face a number of pressures from human activities, including over-exploitation; degradation of critical habitats; invasive alien species; pollution, including excess nutrients, toxic pollutants, and litter; and the use of non-selective
fishery gear (e.g., drift nets and purse seine nets) (UNEP/
MAP/MED POL 2005).
While there is no evidence of species loss in the Mediterranean, the status of a number of speci...

Threatened species in Zimbabwe
Through the intensified conservation programmes, including the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE), the number of threatened species was reduced from 38 in 2000 to 32 in 2004. CAMPFIRE is a community-based natural resource management programme in which Rural District Councils, on behalf of communities on communal land, are granted the authority to market wildlife in their district to safari operators who then s...

Historical decline of the Caspian seal (Pusa caspica)
It is unclear how many seals remain in the Caspian Sea. From a population estimated at more than one million in the early years of the twentieth century, population estimates now vary between
110 000 and 350 000. For more than 100 years, hunting of seal pups was carried out in the frozen North Caspian area each winter. In the early twentieth century, nearly 100 000 seals were
hunted each year; later a quota was set at 40,000 pups per year, furt...

Biodiversity loss: state and scenarios 2006 and 2050
These projections of biodiversity loss from 2000 to 2050 were produced by the GLOBIO consortium for UNEP's Global Environment Outlook 4. Across the GEO scenarios and regions, global biodiversity continues to be threatened, with strong implications for ecosystem services and human well-being. All regions continue to experience declines in terrestrial biodiversity in each of the scenarios. The greatest losses are seen in Markets First, followed by ...

The economy of legal wildlife trade
The trade in wild species can contribute significantly to rural incomes, and the effect upon local economies can be substantial. The high value of wildlife products and derivatives can also provide positive economic incentives to provide an alternative to other land use options for the local people - to protect wild species and their habitats, and to maintain the resource for sustainable and profitable use in the medium and long term. Consequent...

Status of terrestrial ecoregions - threats and vulnerabilities
In a World Wildlife Fund for Nature (WWF) study, experts identified 200 periority terrestrial ecoregions - defined as large scale ecological systems with characteristic flora, fauna and climate with high priority for conservation. Furthermore, as presented in this map, the 200 ecoregions were ranked based on their current and future threats and conservation status. From the study - 47% of the terrestrial ecorgions are considered critical or endan...
