Koeru liigirikas salukuusik paikneb Kesk-Eestis. Seal on esindatud nii küps mets kui ka erinevas vanuses raiejärgsed metsad. Koeru salumetsas uuritakse taimekoosluse struktuuri, samuti metsamajanduse mõju alustaimestikule. Eriti põhjalikult on uurimise all aga taimejuurtes elavate sümbiontsete arbuskulaar-mükoriissete (AM) seente elurikkus. Praeguse informatsiooni kohaselt on Koeru salumets maailma kõige kõrgema AM seente mitmekesisusega ökosüsteem. Välieksperimentides püütakse selgitada, milline on AM seenekoosluste mõju alustaimestiku taimeliikide uuenemisele.
