Flora Raetica Logo

A cit­i­zen sci­ence project for peo­ple inter­est­ed in plants.

Knowing the plant diversity in Graubünden, assessing it
and documenting it for the future —
that is the aim of Flora Raetica.

100 years ago, botanists Josias Braun-Blan­quet and Eduard Rübel com­pre­hen­sive­ly doc­u­ment­ed the flo­ra of Graubün­den for the first time. Now it’s time for an update.

The century update
of the Grisons plant world.
