## Forest Landscape Pathology

**Examiner: David Rizzo**

### Landscape-level disease management

Several papers on the landscape-scale approach to forest disease:

- Gilbert and Hubbell (1996)
- Hansen and Goheen (2000)
- Holdenrieder et al. (2004)
- Meentemeyer et al. (2012)

Case studies in forest from Tainter and Baker (1996). For each of these, read 1-2 refs to understand the relationships between tree-, stand-, and landscape-level processes, and how management approaches to the disease reflect these processes. How do the disease, ecosystem properties, and social context affect the efficacy of approaches such as resistance breeding, silvicultural treatment, eradication, spread-slowing?:

- Root system decay
- Needle Blight
- White pine blister and fusifirm rust
- Dwarf mistletoe

Do the same for insects from our forest outbreaks seminar

- Gypsy Moth
- Bark beetles

### Sudden Oak Death

In addition to ecological papers by David Rizzo about Sudden Oak Death ecology, papers and reviews on the biology of the organism:

- Rizzo et al. (2005)
- Grünwald et al. (2012)
- Swiecki and Bernhardt (2013)
