[.ca] Fruit Key and Twig Key to Trees and Shrubs (ISBN 0486205118)

a technical field guide:
This is the guide I take with me on walks in the winter, when all the leaves are off the oak forest here in southeast Massachusetts. To be honest, I haven't had an opportunity to use the fruit key yet. Remember that this book is ONLY a key, so you'll need other references to learn. I've found the key to be technical and a bit unwieldy on occasion, but by the same token, it's opened a new level of detail to my observation: an eye loupe comes along for those walks...

What to do till spring comes:
If you're a tyro or a practiced botanist, you'll find this helpful. Take it along on walks in the dreary seasons, and you'll find a wealth of fascinating things to keep you busy bushwatching. Easy to use and not too technical.
