Study of past ecosystems allowed to demonstrate, for instance, that numerous contemporary
biotopes (like the "
wild" Slovenian forests for instance), supposedly largely untouched, were in fact very remote from their
natural vegetation. In Japan,
Akira Miyawaki demonstrated after study that, on the one hand, long supposed "native species" had in fact been
introduced on account of human intervention since over 1000 years (especially,
coniferous being privileged over
deciduous). On the other hand, that
reforestation with
"original" species gives good and often spectacular results.
Maps of potential natural vegetation are used worldwide for improved ecosystem comprehension and
management. ==Criticism==
