Identification Resources: getting started

If you're just starting out with plant identification, check out our Helpful Hints here: you'll find a review of plant ID books in print, tips on ID resources, and links to some groups on social media which offer ID help or which talk you through the various stages in identifying a plant.

Then head over to our plant ID: getting started page for helpful ID sheets and webpages.

Identification Resources for experienced botanists

BSBI publishes a range of Handbooks for difficult plants as well as Floras, ID keys, a selection of Species Accounts and the Plant Crib.

Many of the files from the Plant Crib are available for you to download free of charge from the Plant Crib page.

We also have lots more resources for experienced botanists on this new page

*NEW* Help trial a new, free resource for identifying wetland plants. John Poland has teamed up with the Freshwater Habitats Trust to produce a draft Vegetative Key to Wetland Plants. Download your free copy from this page, test the key in the field and then ask to join this (closed) Discussion Group and tell fellow botanists how you got on. They are asking for feedback from botanists at all skill levels, beginner to expert, so please take part.
