The resulting monocultures have raised concerns about loss of biological diversity, through loss of acorns that mammals and birds feed on, absence of hollows that in oak trees provide shelter and nesting sites for birds and small mammals and for bee colonies, as well as lack of downed trees in managed plantations. These arguments have caused experts and citizens in California and the Bay Area to debate the merits of Eucalyptus removal versus preservation.
