Peterson First Guides are the first books the beginning naturalist needs. Condensed versions of the famous Peterson Field Guides, the First Guides focus on the animals, plants, and other natural things you are most likely to see. They make it fun to get into the field and easy to progress to the full-fledged Peterson Guides.
This was my first Peterson First guide and I found it an interesting read. I think it would be a very good basic field guide, but it is not particularly applicable to my area of Florida on the Gulf of Mexico. This book would be my go to book to narrow down family and species before continuing to a more detailed guide.
