potential natural vegetation
Potential natural vegetation (PNV) is an ecological concept referring to the vegetation that would be expected given environmental constraints (climate, geomorphology, geology) without human intervention or a hazard event.
The concept has been developed in the mid 50s by phytosociologist Reinhold Tüxen, partly expanding on the concept of climax.
==Concrete applications==
PNV is widely used in modern conservation and renaturation projects to predict the most adapted species for a definite ecotope. Native species being considered having optimum ecological resilience for their native environment, and the best potential to enhance biodiversity.
To determine "natural" vegetation, scientists research the original vegetation of a land through retrospective ecology.
