and from last year, US specific, endangered species:

A comparative assessment with data from the 2010 Red List reveals an increase in the proportion of threatened species recorded as being impacted by certain threats. Notably, the incidence of hunting and trapping as a documented threat has increased from 34% to 41% of threatened species. Similarly, the proportion of species assessments with fire/fire suppression, climate change, pollution, invasive alien species and energy production have each increased by 3-5 percentage points.
