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.
Undersøgelse af fortidige økosystemer gav f.eks. muligheder for at påvise, at talrige nutidige biotoper (som de “vilde” polske skove), som man anså for at være stort set urørte, i realiteten var meget langt fra deres oprindelige tilstand.
