    The natural vegetation pattern of the Mornington Peninsula, with particular reference to the genus Eucalyptus
    Calder, Winifred B. ( 1972)
    The natural vegetation pattern of the Mornington Peninsula, Victoria, has been studied and presented in map form on the basis of: Environmental factors associated with eucalypt distribution and habit are discussed. Vegetation formations are described and evidence presented of dependence on changing equilibria of environmental factors particularly pedological factors. Data obtained from transects across salt marshes are discussed. This indicates the inadequacy of presently available information regarding the delicately balanced environment of this formation. Difficulties in determination and delineation of plant associations are discussed. Because of species gradations it was not possible to satisfactorily separate all associations by subjective determinations alone. Abrupt discontinuity in one or more environmental factors makes it possible to subjectively determine five plant associations. A further twenty associations were determined by computer analysis of qualitative floristic lists. Delineation and problems of field recognition of these twenty statistical associations is discussed with reference to the work of Braun-Blanquet and of Poore. A preliminary attempt is made to correlate environmental factors with distribution of Eucalyptus spp., of vegetation formations, and of plant associations. Appendices include descriptions of soil types in the region; historical evidence which relates to past condition and management of the vegetation; and field data.
