This guide was produced by UKCEH and JNCC as part of the Natural Capital and Ecosystem Assessment Programme. Monitoring pollinators is important. Data on pollinators contributes to research, conservation, and policy. Understanding more about pollinators helps us to protect them and restore their populations. Citizen science is a fantastic way to collect data on pollinators whilst engaging the public in science and conservation. There are many different approaches that can be tailored to your needs, and many existing pollinator monitoring schemes that you can participate in. This guide will help you decide if citizen science is the right approach for you, and to help you choose the best methods. It was written with the users, for the users. We thank all the stakeholders who shared their experience and needs with us during focus groups. They included conservation practitioners, community group leaders, educators, researchers, and policy advisors.
