2.3 Survey and description of standing trees/stemsThe methodology distinguishes a tree from a stem. A tree represents an individual which comprises of one or more stems ? e.g. after bifurcation or in a polycormon. A stem is a stem base which enters the calculation of timber volume (breast height diameter (DBH) exceeds 100 mm) and which occupies a distinct position in the social structure of the vegetation e.g. a stem in a forked tree or one of the stems in a polycormon. All stems with minimal DBH of 100 mm are localized and described. Following attributes are recorded for each tree:identification number of a stemtree number ? every tree is marked by a birth? number of the tree to which all stems from a polycormon or stems from bifurcation belong. Thus these stems have the same tree numberstem position within a tree ? selection from a list Multi-stem type (see Appendix 2a)serial stem number ? indicates the serial number of a stem within a tree (e.g. stems in a forked tree will have serial numbers 1 2)breast height diameter 13 m above ground with an accuracy of 1 cmstem height with an accuracy of 0.5 mtree species ? selection from a list Species? (see Appendix 2b)character of the stem condition ? determines life condition of a stem selection from a list ?Stem feature (see Appendix 2c)upper thickness of a fracture or a stump with an accuracy of 1 cm ? is determined when the stem is in the form of a stump or a fracturecharacter of stem shape ? determines specific stem shapes selection from a list ?Stem distinctive (see Appendix 2d)social status of a stem in the stand ? classification according to condensed Zlatn?k?s scale selection from a list ?Social status (see Appendix 2e)note ? additional information about health status etc.2.4 Survey and description of lying trees/stemsLying stems with minimum DBH of 100 mm are localized; following attributes are recorded for each stem:identification number of a lying stemstem number ? every lying stem is marked by a birth? number of the tree to which it belongsDBH (in cm) in the length of 13 m from the stem baselength of the lying tree with an accuracy of 0.5 mtree species ? selection from a list ?Druh_d?eviny (see Attachement 2b)decomposition degree ? a state of decomposition is determined selection from a list ?Stupe?_rozkladu (see Appendix 2f)origin of the lying stem ? selection from a list ?P?vod_kusu (see Attachment 2g)note ? additional information2.5 Survey and description of regenerationPlots with uninterrupted regeneration of trees with a minimum height of 0.1 m are localized. Each plot is characterized by these attributes:identification number of the regeneration plottree species representation; representation is expressed in % of the number of individuals of each tree speciesdensity of individuals in the regeneration plot the average number of individuals per m2 is recordedaverage height in the regeneration plot with an accuracy of 0.5 mnote includes e.g. information about protection measures for restoration damage origin of restoration2.6 Survey and description of stumpsStumps ? stem bases with roots remaining after the fall of a tree and with a height up to 1.5 m are localized. Each stump is characterized by these attributes:identification number of a stumptree species ? if recognizable ? selection from a list ?Species (see Appendix 2b)stump diameter (in cm) at the cutting facestump origin ? we distinguish a stump formed naturally and a stump form artificially which was created by logging selection from a list ?Stump origin (see Appendix 2h)note ? additional information2.7 Survey and description of a transectTransects are selected in the most characteristic parts of the research objects in different development stages. Following objects are localized and/or described in each transect:borders of the transect; width and length are measuredvertical terrain profileposition of standing trees; position and attributes are known from the basic tree measurementshorizontal crown projections of individual treesvertical crown projections in the north-south directionvertical crown projections in the east-west directionlying trees; position and attributes are known from the basic measurements of lying dead treesplots with uninterrupted regeneration; position and attributes are known from the basic tree measurementsvertical profiles of uninterrupted regenerationindividuals of regeneration; attributes of tree species height (with an accuracy of 0.1 m) and a relevant note are recordedposition of stumps; positions and attributes of stumps are known from the basic measurement of stumps Unit of abundance = IndCountInt, Unit of biomass = AboveGroundBiomassCitation(s)
