CHARMEY

This wetland is home to the rare sanguisobre butterfly, which flies when the burnet flowers are in bloom. It's a 30-minute walk and 120 metres of ascent.
The life cycle of the Sanguisobre blue butterfly contributes to its vulnerability. It lays its eggs in July on the flowers of the sanguisobre officinale. Once they have hatched, the caterpillars fall to the ground and attract ants to take them away and feed them. After spending a winter in the anthill, the caterpillar continues its growth and becomes a chrysalis before starting the cycle all over again.

The Lidderey area is made up of low marshes, areas typically caused by excess water. Rainwater feeds the low marshes, but also the water table and run-off water, which is richer in nutrients. This allows different plant species to thrive. The presence of reeds, sedges, mullein and marsh marigold are examples of plants adapted to wet conditions.

Man's impact on the marshes, particularly through farming, is endangering these environments. [Nevertheless, low marshes need to be maintained. Late mowing is necessary to prevent overgrowth. Lack of water and the direct impact of man - trampling, drainage and filling in - are major threats to the survival of the low marshes.

The marsh is accessible by public transport: get off at the Village stop.
