Description
| - This paper presents data on the total biomass and element pools (C, N, P, Ca, Mg, Na, K, Al, Fe, and Mn) of the tree layer in the catchment of Plešné Lake in the Bohemian Forest (Šumava, Bömherwald, Czech Republic). The results are based on terrain measurement and semi-automatic image analyses of aerial orthophotos. The catchment weighted mean total biomass of trees was low (133.6 t ha–1 dry weight). Needles represented 5.4 % (7.3 t ha–1), branches, roots 14.0 % (18.6 t ha–1), and stems 70.6 % (94.4 t ha–1) of the total forest biomass.The wood and bark represented 66.8 % (89.3 t ha–1) and 3.8 % (5.1 t ha–1), respectively, of the stem biomass. The catchment weighted mean element pools were 568.0 and 2.96 mol m–2 for C and N, respectively, and 76.4, 601.5, 133.0, 38.8, 347.0, 19.4, 6.2 and 35.4 mmol m–2 for P, Ca, Mg, Na, K, Al, Fe, and Mn, respectively. These pools represented lt;1-37% of their total pools (soil + forest and herb biomass) in the the catchment. Pools of Ca and Mg in the tree bio
