Disturbance response in vegetation after a bog slide

In the mire of La Vraconnaz located in the Jura Mountains a bog slide occurred in September 1987 that affected 15 ha on the western part of the mire. The bog slide caused a total change in the hydrological and pedological conditions of the mire thus offering the opportunity to study the vegetation dynamics in relation with the disturbance. One hundred permanent plots were selected in 1988 and sampled at regular intervals. Secondary succession is followed on bare peat. With 20 years vegetation records we are now able to make detailed statements about vegetation succession.
