I give this book 9 out of 10 acorns
This is the book that sums up most of Martin Crawford's lifelong work in forest gardening in cool/cold temperate climate. When Martin took his PDC in 1992, he visited Robert Hart's forest garden and probably that is the day he was struck by this never ending story of interacting with natures untold rules, and the day he devoted his life to forest gardening in a scientific way. The book is a recollection of extensive work he has done in the past twenty years at the agroferestry research trust. Martin Carwford has published a lot of his work in small pamphlets divided by plant specifics, they are visible on the site of the agroforestry research trust, here the link to the useful plants booklets:

But in this work he recollects all these single pubblications in one volume of enciclopedic value.
The book is intended for the designer of a forest garden but can be easily read by the home gardener, and found inspirational.
The author takes us through a walk in a forest garden, starting from the design basics, and then hopping through the layers of the forest garden, listing the plants that go in each layer: canopy, shrub, groundcover and herbaceous, and annuals, biennials and climbers. Every list has then its section on designing the specific layer.
There is then a section on extra design elements ans paths, clearings and fungi. I reckon this work as a useful companion of Dave Jacke's and Eric Toensmeiers book, Edible forest gardens. The work of Martin results in being more accessible and direct, maybe less in depth on all the possible plants we can fit in a forest garden, but very thorough and clear on the plants it lists.
The book has 336 pages in full color, and this really makes the difference. The great boxed info for every plant is well edited, the reader finds a quick reference on plant specifics: Deciduous/Evergreen, climate zone, Sun/shade preference, Shade tolerance, Performance rating and Fertility. Then we get into the descritpion of size, width and height as an adult, uses, harvest and storage secondary uses, etc.
There is the nice info on how much in good condition one can harvest from a single plant for many species, and thats the sort of info I really appreciate.
The book is a must fr those interested in forest gardening, even if not based in UK. There is a good list of resourses and links to nurseries and seed sellers that have online shops that isn very useful.
