Biotechnology has the potential to be a part of the solution in protecting forest trees against destructive pest and disease outbreaks

The world's forests support the planet's diverse creatures, and keeping forests robust also could help humanity achieve some of its biggest goals.

The compilation of papers in this proceedings is based on a symposium sponsored by the Insect and Diseases Working Group (D5) at the 2007 Society of American Foresters (SAF) convention in Portland, Oregon. The selection of topics parallels the research priorities of the Western Bark Beetle Research Group (WBBRG) (USDA Forest Service, Research and Development), which had been recently formed at the time of the symposium. Reflecting a unique partnership within the Forest Service, each paper was jointly prepared by a research scientist with the WBBRG and one or more entomologists with Forest Health Protection (USDA Forest Service, State and Private Forestry). Among these papers is a description of the currently elevated impacts of bark beetles in the Western United States; descriptions of the current state of knowledge of bark beetle response to vegetation management and also to climate change; discussions of the complex interactions of bark beetles and fire and of the complex ecological and socioeconomic impacts of infestations; an overview of the use of semiochemical (behavioral chemicals)-based technology for conifer protection; and a case study exemplifying efforts to assess risks posed by nonnative invasive bark beetles.

In late-June, Delaware’s forests get an annual “physical” or “check-up” – just after spring’s “leaf-out" blankets the state in a wave of green color. Just as people should visit the doctor to be screened for potential diseases, trees are examined with a variety of tools to hopefully spot minor issues before they turn into major ones. Armed with a digital camera, GPS technology, and a tablet equipped with specialized software and satellite data, forest health specialist Bill Seybold boards a small plane for a sky-high view of the First State. The annual aerial survey is specifically designed to detect potential threats that can only be seen from the air. Fortunately, early results from the 2018 aerial forest survey indicate no major outbreaks of tree diseases or insect pests.
