Research overview: infrastructure expansion and felid habitat fragmentation

Roads, railways, dams, and energy infrastructure are expanding rapidly through tropical and montane cat habitat, fragmenting landscapes and opening forests to settlement and hunting. This overview surveys research on the ecological footprint of infrastructure, the contagious development that follows new roads, and how these pressures intersect with cat ranges from the Amazon to Asia. It reviews planning tools that seek to steer development away from critical habitat and corridors. The synthesis frames infrastructure as a leading edge of land-use change for cats, explaining why a single new highway can trigger a cascade of deforestation and isolation, and why proactive spatial planning is promoted to reconcile development with the connectivity wide-ranging felids require.
