This publication presents a selection of papers from the conference "Mountain hay meadows – hotspots of biodiversity and traditional culture" held on 7-9 June 2010 in Boros Valley, Transylvania, Romania.
The conference was part of a project of the same name. The project had a dual goal: to carry out biological research on mountain hay meadows in two contrasting sites in the Eastern Carpathians; and to help local farmers to carry on traditional small scale agriculture. We also used our project and the conference to celebrate and promote the International Year of Biodiversity 2010.
