POPULATION SIZE
• In the 1890’s, the Amur Tigers
was a total number of more than
3000 individuals it declined
sharply within a century.
HABITAT LOSS
• To simulate habitat loss, conserves
developed five scenarios: reducing the
size of each patch by 10%, 20%, 30%,
40%, and 50%, respectively. In reality,
habitat loss inevitably leads to changes
in the degree of habitat fragmentation
or connectivity. However, to avoid the
compound effects of habitat
fragmentation, conserves assumed the
distances between patches remained
the same so that the effects of habitat
loss could be isolated.
HABITAT DEGRADATION
• Habitat degradation due to logging,
fires, and other human activities
leads to prey scarcity which in turn
results in a decrease in the
fecundity of tigers. Tigers may
adjust their behavior to cope with
the problem of declining habitat
quality by expanding their home
range within the distribution area of
suitable habitat
