Relating to or characterized by an inability or unwillingness to regenerate; describing systems or organisms that do not restore themselves.
From 'a-' (without) combined with 'regeneratory' (from Latin 'regenerare' with the suffix '-ory' meaning relating to). A more formal variant of 'aregenerative.'
Some ecosystems become aregeneratory when they're damaged too severely—the soil loses nutrients faster than plants can rebuild it, creating what ecologists call 'dead zones' that take decades to recover.
