This function calculates for each plot and year the volume logs and standing dead wood per hectare and per decay stage.

calc_deadw_decay_plot(plotinfo, data_deadwood = NA, data_dendro_calc = NA)

Arguments

plotinfo

dataframe on surveyed plots with variables plot_id, plottype, forest_reserve, survey_trees, survey_deadw, period and year_dendro (output of function load_plotinfo())

data_deadwood

dataframe on logs with variables plot_id, plottype, date_dendro, species, decaystage, calc_volume_m3, period and year (output of function load_data_deadwood())

data_dendro_calc

dataframe on stems (shoots and trees) as given from the function calc_variables_stem_level()

Value

dataframe with columns plot, year, decaystage, vol_log_m3_ha
