Abstract
We planned and implemented the SMEAR II and I measuring systems to measure material and energy fluxes between forest ecosystem and its surroundings and within the ecosystem. In addition, we measured the processes generating the fluxes and environmental factors affecting the processes. We constructed SMEAR I in 1991 and SMEAR II in 1994–1996. The mass and energy fluxes play an important role in our physical and physiological theory of forest ecology. The construction principle of SMEAR measuring stations is coherent with our theory, and this is why the data obtained at SMEAR stations have been useful in the development and testing of our theory.
