By killing and decaying roots, root rotting fungi reduce growth, decrease tree vigor, and cause windthrow and death.

  2. Pest risk assessment of the importation into the United States of unprocessed Eucalyptus logs and chips from South America

    In this report, we assess the unmitigated pest risk potential of importing Eucalyptus logs and chips from South America into the United States. To do this, we estimated the likelihood and consequences of introducing representative insects and pathogens of concern. Nineteen individual pest risk assessments were prepared, eleven dealing with insects and eight with...

  3. Ecology of Guam’s Casuarina equisetifolia and research into its decline

    On Guam, the estimated lifespan of Casuarina equisetifolia subsp. equisetifolia is 35 to 90 years and trees may reach a height of 24 m and a diameter at breast height of 92 cm. The majority of its trees are monecious. In 2002, it was noticed that many trees were in a slow decline and when felled, droplets often formed on their fresh stumps. In 2009, this condition was...

  4. New diagnostic tools have led to important new discoveries

    Although sudden oak death has been the primary concern for California oak woodlands over the last 20 years, other fungal pathogens of oak (Quercus spp.), California bay (Umbellularia californica), and tanoak (Notholithocarpus densiflorus) also occur in California. Many cosmopolitan...
