    此地點的物種說明:
    Lone manzanita (Arctostaphylos myrtifolia) is a rare, endemic, evergreen shrub restricted to Ione formation soils (infertile, acidic, sedimentary oxisols) in the foothills of the Sierra Nevada, the widely distributed A. viscida (whiteleaf manzanita) intermixes with A. myrtifolia at the margins of Ione formation soils. Root and crown rot caused by P. cinnamomi on A. myrtifolia and A. viscida has been reported, please see Swiecki & Bernhardt, 2003 for the first report of root and crown rot affecting native stands of A. myrtifolia and A. viscida.

    影響:
    降低本地生物多樣性: Ione manzanita (Arctostaphylos myrtifolia) is a rare, endemic, evergreen shrub restricted to Ione formation soils (infertile, acidic, sedimentary oxisols) in the foothills of the Sierra Nevada (near Ione). The widely distributed A. viscida (whiteleaf manzanita) intermixes with A. myrtifolia at the margins of Ione formation soils. Swiecki and Bernhardt (2003) examined mortality rates in this mixed vegetation and using scientific testing determined that wilting, foliage desiccation and root necrosis was being induced in the plants by the pathogenic fungus P. cinnamomi. This is the first report of root and crown rot caused by P. cinnamomi on A. myrtifolia and A. viscida. This disease will significantly impact conservation of the already threatened A. myrtifolia (Swiecki and Bernhardt 2003).
