Project
The main aim of this project is to test the general hypothesis that management history in the past 200 years has been a formative driving factor of temperate forest biodiversity at species and functional levels. Management effects are conceptually divided into two aspects: a) immediate influence as pulses – management events at time points in the history of studied forest sites, b) long-lasting legacy of particular management events. Historical management is considered in relation to other anthropogenic factors, such as changes in atmospheric deposition and climate change to assess the relative contribution of each of the major drivers.
