Bartlett Tree Research Laboratories

Bartlett Tree Research Laboratories. Established in 1927 by Francis A. Bartlett, the founder of The F.A. Bartlett Tree Expert Company, it is one of the oldest and most prominent private research institutions dedicated exclusively to the science of arboriculture. Its mission is to conduct scientific investigations into the health, care, and preservation of trees and shrubs, translating findings into practical applications for the industry. The laboratories have played a pivotal role in advancing the field through rigorous, evidence-based research on tree diseases, insect pests, soil management, and plant health care.

History

The institution was founded in 1927 by Francis A. Bartlett at the original company headquarters in Stamford, Connecticut, reflecting his deep commitment to applying scientific principles to the then-emerging profession of commercial arboriculture. Early work focused on combating devastating pests like the gypsy moth and Dutch elm disease, which were causing widespread damage to North American forests and urban canopies. In 1965, under the leadership of Robert A. Bartlett Sr., the research headquarters were relocated to a purpose-built facility in Charlotte, North Carolina, to be closer to a wider range of climatic zones and tree species. Throughout its history, it has maintained a continuous research program, collaborating with institutions like the University of Massachusetts Amherst and the USDA Forest Service to address emerging threats to tree health.

Research and Development

The core research programs are interdisciplinary, integrating plant pathology, entomology, soil science, and tree physiology to develop holistic plant health care strategies. Scientists investigate the biology and control of key pests such as the emerald ash borer, hemlock woolly adelgid, and Asian longhorned beetle, as well as diseases like oak wilt and Phytophthora root rots. A major focus is soil management, including the study of mycorrhizae, fertilization techniques, and the mitigation of soil compaction in urban environments. The development of diagnostic techniques, treatment thresholds, and best management practices for Integrated Pest Management are central outputs, directly informing the services provided by arborists worldwide.

Facilities and Locations

The primary research headquarters and main campus are located on a large property in Charlotte, North Carolina, featuring extensive laboratories, greenhouse complexes, and experimental field plots. This site allows for the study of a broad spectrum of temperate and subtropical tree species. Additional field research stations and collaborative trial sites are maintained in key geographic regions across North America and Europe to study local and invasive issues under varying environmental conditions. The facilities are equipped with modern instrumentation for molecular diagnostics, soil analysis, and entomological research, supporting both applied field studies and advanced scientific investigation.

Key Personnel and Leadership

The laboratories have been directed by notable scientists who have shaped modern arboriculture. Early leadership included figures like L.C. Chadwick, who contributed significantly to urban forestry practices. Later, directors such as Dr. Bruce R. Fraedrich, a renowned plant pathologist, and Dr. Christopher J. Luley, an expert on decay detection and tree risk assessment, expanded the scope and impact of the research. The scientific staff typically comprises Ph.D.-level researchers specializing in their respective disciplines, many of whom hold adjunct faculty positions at universities and are active in professional societies like the International Society of Arboriculture and the American Phytopathological Society.

Contributions to Arboriculture

Its contributions are foundational, having established many of the scientific protocols and treatment standards now considered industry norms. Pioneering research on tree injection and microinjection technology revolutionized the targeted delivery of pesticides and nutrients. The laboratories were instrumental in developing and refining soil amendment practices, cabling and bracing standards, and decay detection methods. Its ongoing Long-term research on tree responses to environmental stress, construction damage, and climate change provides critical data for sustainable urban forest management. By disseminating findings through its technical reports, the Arboriculture & Urban Forestry journal, and educational programs, it has elevated the entire practice of professional tree care.
