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
