“…Water surveys have been popularised across the world, particularly in regions where early detection of an infested area is important to the success of containment and eradication efforts. In Oregon, Washington and California, the USDA conducts annual surveys of Phytophthora species from soil and waterways to ascertain if P. ramorum has escaped into native ecosystems (Frankel 2008;Sutton et al 2009). …”

During one spring season, 12 Phytophthora species, two Phytophthora hybrids, three Halophytophthora species and three Phytopythium species, were isolated from 48 waterways across Western Australia. The waterways were sampled using nylon mesh bags containing leaf baits of up to six different plant species and were isolated by plating necrotic lesions on these onto Phytophthora-selective agar media. Phytophthora species were isolated from all except one waterway. Of the Phytophthora species isolated, eight are known while the remaining four are undescribed taxa. Six of the Phytophthora species and the two hybrids are from clade 6. The two hybrids and P. inundata were the predominant species recovered.Recoveries from different plant leaf baits varied with the best two baits being Pittosporum undulatum and Banksia attentuata; and from these two combined all Phytophthora species were isolated. There was a marked difference in the Phytophthora diversity in the waterways from different regions. This is the first comprehensive study from Australia to examine the Phytophthora communities in waterways, and advances our understanding of the role of these oomycetes in natural and anthropized ecosystems.

“…The same pattern applies to the proportion of forest-related studies mentioning "tree diseases." The stable proportion of forest-related studies mentioning forest health (or tree diseases) over the last two decades is remarkable, given the emergence of many new threats to forests, some of which have attracted considerable research interest (e.g., Sudden Oak Death [84], the Emerald Ash Borer [85] and European ash dieback [32]). Interestingly, fewer publications are retrieved when searching for "tree disease" compared to "tree health" (as well as for "forest disease" compared to "forest health").…”

Abstract:Maintaining forest health is a worldwide challenge due to emerging tree diseases, shifts in climate conditions and other global change stressors. Research on forest health is thus accumulating rapidly, but there has been little use of scientometric approaches in forest pathology and dendrology. Scientometrics is the quantitative study of trends in the scientific literature. As with all tools, scientometrics needs to be used carefully (e.g., by checking findings in multiple databases) and its results must be interpreted with caution. In this overview, we provide some examples of studies of patterns in the scientific literature related to forest health and tree pathogens. Whilst research on ash dieback has increased rapidly over the last years, papers mentioning the Waldsterben have become rare in the literature. As with human health and diseases, but in contrast to plant health and diseases, there are consistently more publications mentioning "tree health" than "tree disease," possibly a consequence of the often holistic nature of forest pathology. Scientometric tools can help balance research attention towards understudied emerging risks to forest trees, as well as identify temporal trends in public interest in forests and their health.

“…Previous tree disease outbreaks have been documented and commented on. In the USA for instance, the chestnut blight (Cryphonetrica parasitica) epidemic of the early twentieth century, which killed over 300 million native trees and profoundly altered the landscape of the eastern seaboard of the United States, is a frequently invoked point of historical reference in that country when present-day disease threats are under discussion (see, for instance [6,7]). In the UK, the Dutch elm disease (DED) outbreak of the 1970s, responsible for the death of some 30 million trees, has been the subject of various retrospective commentaries and expressions of regret [8,9], as well as an ongoing and very productive programme of plant pathology research.…”

Expanding international trade and increased transportation are heavily implicated in the growing threat posed by invasive pathogens to biodiversity and landscapes. With trees and woodland in the UK now facing threats from a number of disease systems, this paper looks to historical experience with the Dutch elm disease (DED) epidemic of the 1970s to see what can be learned about an outbreak and attempts to prevent, manage and control it. The paper draws on an interdisciplinary investigation into the history, biology and policy of the epidemic. It presents a reconstruction based on a spatial modelling exercise underpinned by archival research and interviews with individuals involved in the attempted management of the epidemic at the time. The paper explores what, if anything, might have been done to contain the outbreak and discusses the wider lessons for plant protection. Reading across to present-day biosecurity concerns, the paper looks at the current outbreak of ramorum blight in the UK and presents an analysis of the unfolding epidemiology and policy of this more recent, and potentially very serious, disease outbreak. The paper concludes by reflecting on the continuing contemporary relevance of the DED experience at an important juncture in the evolution of plant protection policy.
