Radio telemetry collars have allowed researchers to map detailed nightly movement patterns of large carnivores worldwide.
Telemetry and camera trap studies have documented the nocturnal movement patterns of Sumatran tigers. Individuals may travel over 10 kilometers during a single night while hunting or patrolling territory. Dense tropical vegetation does not significantly impede their movement. Such mobility is essential for locating prey and deterring rival males. However, roads and plantations interrupt these nightly circuits. Fragmented landscapes force detours that increase energy expenditure. What appears vast to humans is often barely sufficient to a territorial carnivore. Movement freedom defines survival.

Large nightly ranges highlight the importance of continuous habitat corridors. Even small infrastructure barriers can disrupt established routes. When highways bisect forests, vehicle collisions become additional risk factors. Conservation planning must account for movement ecology, not just static habitat maps. Protected areas that look sufficient on paper may fail if connectivity is severed. Spatial scale is central to predator persistence.
For local residents, a tiger’s 10-kilometer patrol may cross farmland, forest edge, and riverbanks within hours. The invisibility of such movement fuels both awe and anxiety. Knowing that a critically endangered predator can traverse significant distance overnight complicates coexistence planning. Survival depends not only on forest acreage but on uninterrupted pathways. In a fragmented world, distance becomes contested territory.
