Ussuri Taiga Habitat Compression Reduced Amur Leopard Territory to a Narrow Forest Strip

A predator that once roamed across three countries now survives in a forest corridor thinner than many urban metro lines.

The Ussuri region is also home to the endangered Amur tiger, sharing overlapping habitat.

The Amur leopard’s remaining habitat lies primarily within the Ussuri taiga of Russia’s Primorye region and adjacent Chinese forests. Historically distributed across northeastern China and the Korean Peninsula, its range contracted to a fraction of that territory by the early 21st century. Industrial logging, agriculture, and settlement fragmented contiguous forest into isolated patches. Leopards require expansive territories, with males covering large areas to access mates. Compression into a narrow corridor intensified competition and limited dispersal. Habitat contraction thus created both demographic and behavioral stress. The geographic shrinkage mirrored population decline.

Taiga ecosystems function as complex networks of coniferous forest, prey species, and seasonal climate cycles. Fragmentation interrupts these ecological interactions. Conservation authorities prioritized restoring landscape connectivity through protected corridors. Land management decisions began integrating predator mobility into zoning frameworks. The economic trade-off between timber extraction and biodiversity preservation became explicit. Habitat width now directly influences species survival probability.

The narrowing of territory reflects a broader global pattern of carnivore confinement. Large predators increasingly persist in ecological remnants rather than expansive ranges. For the Amur leopard, survival depends on preserving enough forest width to sustain natural behaviors. The species became geographically precise in a way evolution never intended. Its survival map now fits on a regional planning document. That compression is both measurable and precarious.
