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.

Explore the progress of mapping in each region and find out where observations are still needed.
