How can you help?

Record flying squirrel observations in laji.fi or iNaturalist Suomi. This information supports management directly by discovering and monitoring the presence of flying squirrels.
Collect flying squirrel droppings from your area and send them to our lab at the University of Oulu. There, we are building a collection of samples that shape the basis of on-going and future research (see our flying squirrel research page), such as the development of new monitoring tools. Furthermore, we will share the results we have gathered from your samples with you as the research is progressing! Contact us in the form below, or directly via email.
Reach out and share your personal stories and insights about flying squirrels – both good and bad. Do you have concerns? Do you have questions? Let us know!
