She is known for her ability to bring an understanding and appreciation of the scientific complexities of nature to the general public. In the foreword to one of her books, Arboretum America, a Philosophy of the Forest, E. O. Wilson wrote, "Diana Beresford-Kroeger is one of the rare individuals who can accomplish this outwardly simple but inwardly complex and difficult translation from the non-human to human realms".
Beresford-Kroeger was orphaned at a young age and raised in Ireland by a bachelor uncle, Patrick O'Donoghue, who was a noted athlete, chemist, scholar, and bibliophile. He nurtured her quest for knowledge and encouraged her to read and discuss everything from Irish poetry, world religions, and philosophy, to physics and quantum mechanics. She attended private schools in Ireland and England. Her summers were spent in the countryside in West Cork and Kerry, which is where she received the lessons of her folk lineage. A great-aunt taught her the early Irish Brehon law as well as Druidic philosophy and ancient ethnobotanical medicine.
Beresford-Kroeger completed her undergraduate studies at University College Cork (UCC), was graduated first in her year (1963) with a Bachelor of Science first class honours in both, botany and medical biochemistry. She completed a Master of Science degree at UCC in 1965. Her thesis was: Frost Resistance and Gibberellins in the Plant Kingdom. She applied scientific testing to plant and human properties held in common. Her Ph.D. thesis completed in 1972, "The Importance of Indole metabolism in plants and its significance in the human condition."
While engaged in cardiovascular research (1973), she completed a diploma in experimental general surgery from the department of surgery at the University of Ottawa. Beresford-Kroeger completed a Ph.D. in biology at Carleton University in 2018. Her thesis was entitled, Myocardial Ischemia and the use of non-typing artificial blood in hemodilution.
Beresford-Kroeger worked as a research scientist at the University of Ottawa and then at the Canadian Department of Agriculture Electron Microscopy Centre, where she discovered cathodoluminescence in biological materials (1972).
From 1973 to 1982, she conducted research at the University of Ottawa physiology department in conjunction with the Ottawa Heart Institute, specializing in hemodynamics. This work led to more efficient organ transplants, cancer delivery of chemotherapy and oxygenation of damaged cardiac musculature.
In the early 1980s, Beresford-Kroeger refused a professorship in medicine to embark on a significant change in her life work. It began with an expansion of her private research garden and arboretum, Carrigliath. Having identified an absence in the scientific community of the ability to present science to the public and the urgent need to address the degradation of nature, she began her career in writing, broadcasting, and lecturing. Flowing from her research and experience at Carrigliath, Beresford-Kroeger published more than 200 articles in magazines, journals, and newspapers in Canada, the United States, and internationally. She also published seven critically acclaimed books on nature.
She has served as a scientific advisor to a number of organizations, including the Irish Woodland League, Ecology Ottawa, Hidden Harvest of Ottawa, Canadian Organic Growers, Archangel Ancient Tree Archive, the Acadian Forest Research Centre, and others.
Beresford-Kroeger has lectured widely throughout Canada, the United States, Europe, and Japan and has appeared on television and radio in North America, Europe, and elsewhere.
The theatrical documentary, Call of the Forest: The Forgotten Wisdom of Trees, released in 2016, was based on Beresford-Kroeger's book, The Global Forest. The documentary film was produced by Jeff Mckay, Edgeland Films, Merit Motion Pictures, and Treespeak Films. Beresford-Kroeger was principal presenter and created the Director's script. This film is accompanied by an extensive educational app on tree planting in North America, also developed by Beresford-Kroeger http://calloftheforest.ca/. She has also been featured in a number of documentaries, including the PBS documentary The Truth About Trees, produced and directed by Ross Spears.
