A stable plant community that is maintained by regular human disturbance or intervention, preventing the area from reaching its natural climatic climax.
In ecology, an ecological community that persists due to recurring external forces (e.g., fire, grazing, mowing) which deflect the natural successional pathway. It represents a long-term, human-modified steady state.

FAQ
Frequently Asked Questions
It is a stable ecosystem, but it is not the 'natural' climatic climax. It is a human-influenced or biotically maintained steady state.
The terms are often used synonymously. Some ecologists use 'disclimax' more broadly for any deflected climax, while 'plagioclimax' sometimes emphasizes human agency, but the distinction is not strict.
Yes, if the maintaining disturbance (e.g., grazing, fire) is permanently removed, secondary succession would likely resume, potentially leading towards the climatic climax over time.
Yes, a closely mown lawn is a perfect small-scale example. It is a stable grass community maintained entirely by the recurring disturbance of mowing, preventing shrubs or trees from establishing.

Learning
Memory Aids
Mnemonic
Think of 'PLAGIO' as 'oblique' or 'off-course' (like plagiarise is 'off-course' copying) and 'CLIMAX' as the final stable state. A plagioclimax is a stable state that is 'off-course' from the natural climax.
Conceptual Metaphor
A DETOUR ENDING (The natural journey of ecological succession takes a permanent detour due to human 'roadblocks' like fire or grazing, leading to a different, but stable, destination).
