BETA-FOR_SPZ_Deadwood_Aggregated_2014/2024

This dataset contains per patch information of deadwood. The deadwood volume was assessed by measuring in the forest experimentally created dead trees (highstumps, logs, stumps, habitat trees, crowns) and trees that had died naturally (snags). For snags and highstumps the measured diameter is the diameter in brest height, for stumps it is the diameter of the cut surface and for crowns and logs it is the mean diameter. For standing deadwood, a taper of 1 mm per decimeter was assumed. The volume of crowns, logs, cracked snags and highstumps was calculated using the formula: mean diameter²/4 x pi x length. For stumps the formula: diameter²/4 x pi x 10cm was used. The volume of snags and habitat trees was taken from the “Krenn´sche Tarife“ (Hilfstafeln für die Forsteinrichtung, zusammengestellt für den Gebrauch in der Bayerischen Staatsforstverwaltung, herausgegeben vom Bayerischen Staatsministerium für Ernährung, Landwirtschaft und Forsten 1990). Deadwood with a diameter of less than 7 cm was excluded from the recording, and the volume of snags and logs was disregarded once their diameter reached 7 cm or less. In the table “single_objects” each single deadwood object is listed with its volume. In the table “patches” the columns stump_vol, log_vol etc. show the total volume of the measured objects of each deadwood type per patch. The column cwd_vol (coarse woody debris) shows the sum of all deadwood types. The columns stump_vol_ha etc. show the value per ha. The dataset is available for all 234 patches.
