The Hidden Company That Trees Keep: Life from Treetops to Root Tips

Rate this book
A spectacularly illustrated journey into the intimate communities that native trees share with animals, insects, fungi, and microbes

You can tell a lot about a tree from the company it keeps. James Nardi guides you through the innermost unseen world that trees share with a wondrous array of creatures. With their elaborate immune responses, trees recruit a host of allies as predators and parasites to defend against uninvited advances from organisms that chew on leaves, drain sap, and bore into wood. Microbial life thrives in the hidden spaces of leaf scales, twigs, and bark, while birds, mammals, and insects benefit from the more visible resources trees provide. In return, animals help with pollination, seed dispersal, and recycling of nutrients. The Hidden Company That Trees Keep blends marvelous storytelling with beautiful illustrations and the latest science to reveal how the lives of trees are intertwined with those of their diverse companions.

This book is very beautiful and the illustrations are lavish, but I can't help but feel that the author doesn't know who they are writing for as the text is quite dense and not extremely well structured and certainly not poetic or pretty and is paired with quite lovely illustrations which are normally very separate audiences. I quite a bit had to go through the book a second time to go through the illustrations as shifting attention to them from the text was difficult, but that may be a me issue

The book itself is a collection of stuff, if you like reading Wikipedia and clicking through all the related links, this is a fun but less detailed book. Paper quality and illustration quality 5/5

This book was far nerdier then I expected. But it's a testimony to its quality that I feverishly read it cover to cover in little time. Nardi covers a wealth of information and minute observations; a second reading of this book wouldn't begin to exhaust its value for me. I don't think this is an intro- to-ecology book, more like a, so-you-think- you-know-trees? book. The book tells very little about trees. But in a comprehensive nod to ecological interrelatedness, it tells you all about their neighbors. Illustrations on every page helped me visualize the infinite entomology. Bonus: there's a gazillion alive things.

This is a beautiful book. Almost every page has incredibly detailed illustrations done by the author of whatever subject he’s discussing. I learned a lot, and for the most part I enjoyed reading it. I particularly liked the little etymology lesson that came with every new species name.

At times, the book felt repetitive, but I also feel like you aren’t supposed to read it all the way through. If I was putting it down for months at a time (like I did in the very beginning, oops) the repetition would be beneficial.

Personally, I don’t think this one is very useful to me and my curriculum, sure I learned a lot, but mostly about insects. Especially parasitic wasps. I now know a lot about parasitic wasps. I flagged a couple things that could be useful but I don’t actually think this can be classified as a botany book- it’s mostly about bugs!

This book is full of interesting facts and sets out to show the interconnected relationships between between trees and many, many other organisms. I was expecting a more narrative approach but this was much more scientifically descriptive. It's beautifully illustrated throughout. Not quite a reference book, not quite a roadmap, not really a story or a giide either, I'm honestly not quite sure how to sum this one up but will refer to it many times in the future.

I’ll give this book five stars for the extraordinary research behind its pages as well as fabulous illustrations. But to be honest, it took me most of a year to read. I couldn’t read more than 1-2 pages at a time. Finally, 30 pages from the end, I had enough and couldn’t read it anymore. You really, really, really have to love bugs to like this book. I don’t.

An amazing book that gives a pleasantly detailed look at all the amazing lives that are intertwined with those of trees. I highly recommend this book for anyone who is interested in the wildlife in their yard and/or in nurturing the ecosystems around them.

This book is amazing, but it is slow reading as it really it more like a textbook. So much information about so many insects! It was a bit over my head. I plugged along slowly and did enjoy it.

Charming book covering in impressive detail the many other creatures of many different sizes that share space with trees. Beautiful pencil drawings.
