My favorite books on allergy-friendly landscapes

Why am I passionate about this?

I am now considered by many as the expert on creating allergy-free and allergy-friendly gardens and landscapes. I have lectured on the subject all across the US and Canada, and also in Israel, Ireland, the United Kingdom, New Zealand, and Australia. For 30+ years now I’ve been researching the connections between urban landscaping and allergies and asthma. My articles have appeared in dozens of fine publications, including The New York Times, The London Times, The Guardian, The Los Angeles Times, Atlas Obscura, Scientific American, Der Spiegel, and The New Scientist. I have owned two nurseries and taught horticulture for twenty years.

The books I picked & why

Book cover of Medical Botany: Plants Affecting Man's Health

Thomas Leo Ogren Why did I love this book?

This is the best book on medical botany. The authors are both top experts on biology and botany, and among his peers in biology, Walter H. Lewis is known as the medical botanist. Just packed with interesting, useful information not found anywhere else. Widely used as a university textbook for medical botany…but extremely readable. Highly recommended!

Book cover of Oxford Textbook of Nature and Public Health

Thomas Leo Ogren Why did I love this book?

Edited by Matilda van den Bosch and William Bird, Nature and Public Health. Each chapter was written by several top experts in the field.

What is this book about?

Human beings have always been affected by their surroundings. There are various health benefits linked to being able to access to nature; including increased physical activity, stress recovery, and the stimulation of child cognitive development. The Oxford Textbook of Nature and Public Health provides a broad and inclusive picture of the relationship between our own health and the natural environment. All aspects of this unique relationship are covered,
ranging from disease prevention through physical activity in green spaces to innovative ecosystem services, such as climate change adaptation by urban trees. Potential hazardous consequences are also discussed including natural disasters, vector-borne…


Book cover of Airborne and Allergenic Pollen of North America

Thomas Leo Ogren Why did I love this book?

Airborne and Allergenic Pollen of North America was the most important book I read (out of hundreds) when I was doing my original research for my own book. The material is extensive, accurate, scientific, and yet it is quite readable. Unlike so many other books, papers, or articles on pollen and allergy, this book takes into consideration all of the plants grown in North America, not just the trees. A classic, and yet, still the very best.

Book cover of A Natural History of Western Trees

Thomas Leo Ogren Why did I love this book?

I own hundreds of books on plants and trees. The two finest books written on American trees were both written by Donald Culross Peattie. His book on Western trees is amazing. When he looks at and writes about a particular tree, he mentions everything about it. What it looks like, where it grows, how big it gets, what it is used for, what animals, birds, insects use this tree. He also mentions in detail how it flowers, sets seeds, grows….he misses next to nothing. Totally recommended!

What is this book about?

A lovely reprint of Peattie's 1950 classic with the fine wood engravings and a new (4 page) introduction by Robert Finch. This editio printed on alkaline paper. Annotation copyright Book News, Inc. Portland, Or.


Book cover of A Natural History of Trees of Eastern and Central North America

Thomas Leo Ogren Why did I love this book?

A Natural History of Trees of Eastern and Central North America by author and naturalist Donald Culross Peattie is probably the very best book on trees that I have ever read. I used this book (and also his book on Western trees) as a marvelous resource when I was working on my books. 

I learned many a new thing from this book, things I could not find in books written by botanists or horticulturists. This in large part is because Peattie was first and foremost, a naturalist. He tells the reader things that others didn’t bother to mention (for example, that with Honeylocust trees, each branch is of only one sex). The author also has a wonderful way of writing that makes the text come alive…always interesting.  As a naturalist, Peattie looks at the whole picture; one of the few writers about trees who was also a dedicated ecologist. A great book!

Antonieta Contreras Author Of Traumatization and Its Aftermath: A Systemic Approach to Understanding and Treating Trauma Disorders

New book alert!

Why am I passionate about this?

As a trauma therapist and dedicated researcher, I love uncovering valuable insights within lesser-known books. There are hidden gems, free from the pressure of commercial success, crafted by authors deeply committed to research, understanding, and the art of writing itself. Their dedication resonates with me, as I believe in the profound value of information and the power of critical thinking. Through my own book, Traumatization and Its Aftermath, I aim to emphasize that psychological concepts often lose their depth in translation and my mission is spreading awareness and fostering a deeper understanding of trauma and its intricate facets. With that idea in mind, I chose these five titles. 

Antonieta's book list on uncovering the human experience and exploring the depths of trauma

What is my book about?

A fresh take on the difference between trauma and hardship in order to help accurately spot the difference and avoid over-generalizations.

The book integrates the latest findings in brain science, child development, psycho-social context, theory, and clinical experiences to make the case that trauma is much more than a cluster of symptoms to be tamed, but instead best understood as development gone off course, away from growth and towards (only) survival.

This book prompts a profound shift in perception, inviting to view trauma as an intricate and diverse experience, a point of view that ultimately leads to sharper treatment and, hopefully, more healing. It encourages a transition from asking, "What happened to you?" to the deeper question, "What is your relationship with what happened to you?"

Traumatization and Its Aftermath: A Systemic Approach to Understanding and Treating Trauma Disorders

By Antonieta Contreras,

What is this book about?

The book is comprehensive, bold, and practical-a much-needed resource for the assessment and treatment of trauma. Instead of the traditional focus on the overall importance of healing, Traumatization and its Aftermath decodes why some people don't heal as easily as others, analyzes the various failures of diagnosis, and explains how to make therapeutic interventions truly effective.

This book offers a systemic deep dive into traumatization that clarifies myths and misinformation about the entire spectrum of trauma and provides both clinicians and non-clinicians with the right level of validation, preventive measures, conceptualization methodology, assessment tools, and healing facts that have not…
