In the canton of Thurgau about 1,700 ha of forest reserves have been established. Of these, about 250 ha are unmanaged forests. In the 1,450 ha of special forest reserves, the Forestry Department of the canton Thurgau undertakes specific measures to promote forest biodiversity, which will be intensifed in the coming years. The effects will be observed by means of success monitoring. In the article, we present the concept “biodiversity: success monitoring in forest”, which was developed in 2009 and which implements a standardized method for the success monitoring. It is based on forest target types which are defined by ecological objectives. To assess the bio-ecological conditions of a research area or to verify the achievement of objectives, characteristic and rare plants and animal species as well as habitat structures were defined as indicators in each forest target type. The success monitoring is carried out on ten sites of 1 ha each per forest type. Within these areas there are permanent plots with defined sizes. The indicators are monitored either on the 1 ha site or the smaller permanent plots. Since the beginning of 2010, success monitoring is conducted according to this concept. During the first phase, monitoring is concentrated on the relevant forest target types in the canton of Thurgau: “open forest”, “oak-dominated forest with old oaks”, “alluvial forest” and “forest margins”. Success monitoring will continue until 2020. Results and key findings of the monitoring are annually documented in a report.
