In the desire to be scientific and orderly, forests have been managed to cut trees at the point at which wood producing biological processes slow down, and replanted with young and vigorous replacements, leading to a continual wood supply. In order to avoid any competition for nutrients, small and controlled fires are applied to clean things out, and the herbicides to prevent the regrowth of competitive understory. What could go wrong?
Thanks to the frequently unpopular study of "inefficient" and "untidy" old-growth forests, with fallen logs rotting, whatever growing everywhere, older trees, and occasional large fires, we learn a not particularly surprising answer: you've removed habitat for symbiotic creatures that are necessary for fixing nitrogen, cycling nutrients, and fighting pests, leading to a multiple-generation time-bomb as the soil becomes depleted without replacement, creating a system requiring many more inputs in a costly way.
Fortunately, we have a happier ending than in many cases. These discoveries lead to recommendation for a new forestry, which proposes that some logs grow old, the underbrush stays where it is, fallen logs stay where they are, and we make sure cycles stay intact, while still harvesting a reasonable amount of trees. Of course, it's disliked for being both too restrictive and too permissive in the way all fair trade-offs are, but it does have an encouraging influence on policy.
This book gets the narrative arc through the human story of scientific careers, to the ecological dynamics of the forest, to the conflicts of policy right. This book pushes the same buttons as "Eating the Sun" while taking on a topic that is more human scale. This change in scale (mostly talking about the scientists of one particular research forest, mostly discovering observable processes instead of requiring electron microscopes, mostly within the history of the past thousand years rather than since the Cambrian explosion, mostly requiring the forest policy of states and nations rather than the worldwide response to climate change) means that the book can be much smaller while still covering the subject cohesively.
Overall, it is an informative and pleasant story of things going right that is perfectly clear, perfectly paced, and right for our time.
