At the 2019 BSBI AGM, members voted to increase the membership subscription for the first time since 2015. The new rates are shown below and take effect immediately. We think this small increase will enable us to support our loyal members even more effectively in 2020. We hope you'll agree that the new rates still offer excellent value for money.

BSBI's membership special offer for 2019 opened on 1st October: 15 months for the price of 12. Find out about all the benefits of BSBI membership including how you can save money on some great new botany books.

Missed out in October? The November special offer is almost as good: 14 months for the price of 12. If you love British & Irish wild flowers, BSBI membership can help you learn more about them and support their conservation. And you can still save money on those botany books!
