The Sumatran tiger is the smallest surviving tiger subspecies, an adaptation to dense island forests.
The Sumatran tiger survives in increasingly fragmented patches of forest across Indonesia. Habitat fragmentation isolates breeding females into forest islands surrounded by plantations and roads. Small habitat blocks support fewer prey species, limiting food for nursing mothers. When prey declines, cub starvation risk rises sharply. Fragmented landscapes also expose tigers to higher poaching pressure at forest edges. Cub mortality in such conditions can exceed that of more contiguous habitats. Official national counts may show overall numbers, but they rarely detail survival disparities between regions. Genetic isolation further compounds the problem, reducing resilience. Each lost cub in a small fragment represents a significant blow to local persistence.

Fragmentation transforms survival from a biological challenge into a spatial puzzle. Even if anti-poaching efforts succeed, inadequate territory size limits reproductive success. Dispersing juveniles may encounter roads or human settlements before establishing territories. That increases mortality beyond the den stage. Conservation success therefore depends on reconnecting habitat corridors. Without connectivity, cub survival improvements in one patch cannot rescue another. Numbers on a national scale can hide local collapses.
There is also an economic irony. Palm oil expansion contributes to habitat loss while global markets rarely connect products to cub mortality. Consumers thousands of miles away indirectly influence survival odds in Sumatra. Transparent reporting on regional cub survival could sharpen policy debates. Protecting breeding landscapes is more complex than counting adults with camera traps. It requires land-use reform and cross-sector cooperation. For Sumatran tigers, survival is a geography exam with lethal grading.
