Assessing the growth of Picea omorika [Panč.] Purkyně in the Masaryk Forest Training Forest Enterprise at Křtiny

Abstract

Plantations of Serbian spruce (Picea omorika [Panč.] Purkyně) reach an age over 70 years at the Masaryk Forest Training Forest Enterprise (TFE) at Křtiny. They occur at different sites of the TFE, which is situated north of Brno between Blansko, Jedovnice and Brno in the Czech Republic. The paper presents an assessment of primary mensurational values (diameter at breast height d.b.h., height h, Derbholz volume m3), fertility, mortality and general health condition. The present registered number of Serbian spruce trees is 425 (from originally 750 individuals) in 25 localities and 12 GFT (groups of forest types). A comparison of Serbian spruce mensurational data with growth tables indicated that Serbian spruce on GFT 4K makes up for the tabular mean values of Norway spruce (Picea abies [L.] Karst.) in yield class +1.
