However, many of them have been canalised in the last 200 years or so as a measure against flooding and to gain cultivated land. This destroyed valuable biotopes and many plant and animal species were greatly reduced in their populations or disappeared.
Today, numerous watercourses are being revitalised in Graubünden. In these often complex projects, new solutions must be found jointly for all those involved and affected. This effort is worthwhile, because numerous, often rare plants and animals as well as people react positively to upgrading.
During the excursion, experienced experts from the Graubünden Office for Nature and the Environment will provide information about river restoration projects that have been carried out in the Engadine. They will report on their positive effects on animals and plants and show the possibilities and limits of such projects.
