LETS Study Leysin

LETS stands for "Local Environmental Transect Survey". The Leysin American School is carrying out an elevation-based transect and study of the forest ecology of Leysin, Switzerland.

About the project

We have established 13+ 30m X 30 plots from 600m to 2300m in elevation. Inside these plots we are identifying, counting, and measuring the trees, as well as conducting complete species inventories. We do this twice a year with students in the school. Approximately 100+ students visit the plots in October and another 100+ in May.

How can citizens participate?

We welcome the public to help monitor our plots including inventorying species so that we can know when new species arrive. We also welcome other schools sharing our plots in order to contribute to this long-term research. But mostly we want to share our methodology so that other schools will launch their own Local Environmental Transect Surveys. We would like to see schools worldwide doing their own LETS Study ______ (fill in your town).

What happens with the results?

The results so far are in our Excel spreadsheets and in iNaturalist and will be shared on However, we are looking for ways to open up our data for others to use as they wish.
