ASSESSMENT OF ACCURACY OF “VOLUME INCREMENT TABLES FOR PINE” BY ALBERT DUDEK IN PINE STANDS OF THE MUROWANA GOśLINA FORESTRY EXPERIMENTAL STATION

Keywords: volume increment, tables, accuracy, pine
Abstract: The study was an attempt to assess the accuracy of “Volume increment tables for pine” by Albert Dudek in pine stands aged 35, 50 and 88 years, from the Forestry Experimental Station Murowana Goślina. In the 35-year old stand the smallest secondary percentage error in the determination of current volume increment of the stand for a 5- -year growth period was obtained using variant IV of the tables (–2.69%) and in case of a 10-year period for variant I (1.62%). In the 50-year old stand for the shorter growth period it was variant II (–2.21%), while for the longer period it was variant V (–7.94%). In the oldest stand it was table variant III (12.60%) and IV (–6.77%), respectively. Using variants II, IV and V of the tables in the analysed stands current volume increment was determined in diameter subclasses. Irrespective of the applied table variant (in individual diameter subclasses), both positive and negative errors, and the biggest errors (absolute values) were found for trees from the lowest and higher diameter subclasses. In most cases the accuracy of the determination of current volume increment in the analysed stands using tables was consistent with the accuracy expected by their author. Variant V of the tables makes it possible to most accurately estimate volume increment of the stand, irrespective of its age and the length of the growth period.
