Population Declines
Sudden or dramatic population declines are a sign of a species under threat. The articles here focus on declining populations of animals recorded from around the world and examine what's being done to stop shrinking populations from turning into extinctions.
House Sparrows in Decline in Britain
In Britain, scientists have found that in urban and rural areas there are now ten million fewer house sparrows than there were a few decades ago. The decline is more rapid in urban areas when compared to rural regions. London's sparrow population has dropped by sixty percent during the past six years. In rural areas of Britain, populations have fallen the same amount over the past thirty years.

Plummeting Gorilla Population Draws Conservation Funding
Populations of eastern lowland gorillas have suffered tremendously over the past decade. Their numbers have fallen sharply, from 17,000 gorillas in 1994 to only 5,000 in 2004.

Ten Million Fewer House Sparrows
