Threats
A broad genetic sampling of 95 wild Russian tigers found markedly low genetic diversity, with the effective population size extraordinarily low in comparison to the census population size, with the population behaving as if it were just 27–35 individuals. Further exacerbating the problem is that more than 90% of the population occurs in the Sikhote Alin mountain region, and there is little movement of tigers across the development corridor, which separates this sub-population from the much smaller sub-population found in southwest Primorye province.
The winter of 2006–2007 was marked by heavy poaching. Poaching of tigers and their wild prey species is considered to be driving the decline, although heavy snows in the winter of 2009 could have biased the data.

Famous quotes containing the word threats:
“Southerners, whose ancestors a hundred years ago knew the horrors of a homeland devastated by war, are particularly determined that war shall never come to us again. All Americans understand the basic lessons of history: that we need to be resolute and able to protect ourselves, to prevent threats and domination by others.”
—Jimmy Carter (James Earl Carter, Jr.)
“Do not extort money from anyone by threats or false accusation, and be satisfied with your wages.”
—Bible: New Testament, Luke 3:14.
John the Baptist to Soldiers.
“Among the best traitors Ireland has ever had, Mother Church ranks at the very top, a massive obstacle in the path to equality and freedom. She has been a force for conservatism, not on the basis of preserving Catholic doctrine or preventing the corruption of her children, but simply to ward off threats to her own security and influence.”
—Bernadette Devlin (b. 1947)
