Monitoring and evaluating forest dynamics: the Estonian Network of Forest Research Plots (original) (raw)

Abstract

Forest research has long tradition in Estonia that can be followed back to 19th century. Data from long-term forest experiments is available since 1921. These studies were focused mainly on silvicultural treatments and the data has limited application for understanding and modelling ecological processes. Department of Forest Management of the Estonian University of Life Sciences has started the Estonian Network of Forest Research Plots in 1995. Monitoring plots have been continuously re-measured with 5-year interval. Approximately 100-150 permanent sample plots have been measured per year. In 2013, the long-term research network consisted of 714 permanent sample plots, of which 699 have been re-measured at least once, 654 plots - twice and 242 plots - three times. The total number of trees recorded in the network database amounts to 121,042. The plots are systematically distributed throughout the country. Detailed measurements including tree locations are part of the survey protocol...
