urban wilderness

Urban wilderness describes undeveloped or neglected land within a city that has reverted to a wild state—vacant lots thick with weeds, abandoned rail corridors, overgrown industrial sites.

Unlike manicured parks, these spaces exist outside municipal management, hosting volunteer ecosystems of opportunistic plants and urban wildlife.

The term captures the paradox of wildness flourishing amid concrete: The old factory grounds had become an urban wilderness, home to foxes and native grasses.
