"Asset recovery ceiling: Maximum level of passive asset recovery in response to weed removal. Asset recovery threshold: Minimum level of weed removal required to initiate asset recovery. Ecological resilience: Magnitude of asset recovery in response to weed removal. Plant communities with low levels of resilience will experience limited recovery post weed removal and remain in a degraded state without active revegetation. Ecological resistance: Magnitude of change in asset condition in response to weed invasion, usually calculated as the difference in asset condition between weed-dominated and native reference sites. Management impact threshold: Level of weed removal beyond which management inhibits asset recovery. Recovery deficit: Difference between the asset recovery ceiling and the level of asset condition in native (i.e. non-invaded) reference sites. Recovery deficits can be bridged using active regeneration actions (e.g. by reintroducing plants with short-distance dispersal mechanisms as seed or nursery-grown seedlings). Regeneration trajectory: Pattern of change in asset condition through time in response to weed management. Weed removal ceiling: Maximum level of weed removal at which maximum asset condition (i.e. asset recovery ceiling) is reached."
