Book Description
An unusual die-off of tanoaks (Lithocarpus densiflorus (Hook. & Arn.) Rehd.) in the Mill Valley/Mount Tamalpais area of Marin County, California, was first documented in April 1995 (Svihra 1999b, 1999c, 2001), when homeowners reported scattered patches of dying tanoaks-with entire crowns dead and with bleeding basal cankers-to Pavel Svihra, University of California (UC) Cooperative Extension. The symptoms were also being reported by arborists and others on nearby tanoaks, including those at Muir Woods National Monument, and farther south in coastal Santa Cruz County and around Big Sur (Monterey County) in the same year. Heavy ambrosia beetle attacks and black fruiting bodies of a Hypoxylon fungus, later identified as Hypoxylon [Annulohypoxylon] thouarsianum (Swiecki 2001), were associated with the dying trees.

Book Description
Sudden oak death (SOD), caused by Phytophthora ramorum, was first discovered in Oregon forests by aerial survey in July 2001. Since then an interagency team has been working with landowners to eradicate the pathogen by cutting and burning all infected and nearby host plants. The Oregon SOD program now consists of the following elements: early detection; delimitation of infested areas; treatment; research and monitoring; and host reduction in areas of probable disease spread. The Sudden Oak Death Fourth Science Symposium provided a forum for current research on sudden oak death. Ninety submissions describing papers or posters on the following sudden oak death/P. ramorum topics are included: biology, genetics, nursery and wildland management, monitoring, ecology, and diagnostics.

Book Description
The oomycete genus Phytophthora represents one of the most notorious groups of tree pathogens in natural and semi-natural forest ecosystems. Since the discovery in the 1960s of the invasive P. cinnamomi, threatening some of the world’s richest plant communities in Australia, numerous Phytophthora diseases have been reported on forest trees worldwide, which were previously unknown to science. The most notable examples include the oak and beech declines triggered by different Phytophthora spp. in Europe and North America, the findings of sudden oak death and sudden larch death caused by P. ramorum in the Western USA and the U.K., respectively, and the association of P. austrocedri with mal del ciprés in Argentina and juniper decline in the U.K. All these epidemic events are driven by exotic invasive Phytophthora species, introduced through infested nursery plants from their native overseas environments. In recent years, many independent surveys have studied the diversity of Phytophthora species and the diseases they are causing across a diverse range of forests and other natural ecosystems. This Special Issue presents papers on Phytophthora surveys performed in different biogeographic regions and addresses the pathways, and ecological and economic impacts of these invasive forest pathogens.

Book Description
Fungal diseases have contributed to death and disability in humans, triggered global wildlife extinctions and population declines, devastated agricultural crops, and altered forest ecosystem dynamics. Despite the extensive influence of fungi on health and economic well-being, the threats posed by emerging fungal pathogens to life on Earth are often underappreciated and poorly understood. On December 14 and 15, 2010, the IOM's Forum on Microbial Threats hosted a public workshop to explore the scientific and policy dimensions associated with the causes and consequences of emerging fungal diseases.
