| Development of an inventory system for non-timber functions of forests in the frame of management inventories: the case of Greecevon Spyridon Galatsidas, 2001 The development of an inventory and evaluation methodology for non-timber functions of forests in the frame of management inventories is the main objective of the theses. Two systems of factors that can comprehensively describe forest ecosystems and their functions have been developed. The system of external factors comprises the major ecosystem components and provides for evaluation of ecosystem potentials with respect to a function. The system of internal factors includes structural attributes of forest stands and provides for the evaluation of the actual stand conditions regarding a function. Respective variables derived from both systems have been inventoried in the forest of Thessaloniki, Greece to test the evaluation of the functions water percolation and protection against erosion. Principal components analysis has been applied to derive interrelations among variables and reduce the number of variables to deal with. A consecutive cluster analysis resulted to homogeneous groups of land units and forest stands, for which similar management prescriptions as well as silvicultural treatments could be drawn.
