Phytophthora spp. in indigenous forests in Australia

Indigenous forests in Australia are managed primarily for timber production, water production, and conservation. Soil infestation by Phytophthora spp. has the potential to affect all of these. Infestation is widespread but is perceived to affect timber production only in the mixed species eucalypt forests in Victoria and the Eucalyptus marginata Donn ex Sm. (jarrah) forest in Western Australia. It is known to affect water production in Western Australia. As Phytophthora spp. have a very wide host range, site infestation leads to vegetation changes which reduce the conservation value of indigenous forests and similar plant communities in southern Australia
